TXS0108EPWR Description

This device is a non-inverting 8-bit level translator that uses two separate power supply rails that can be set up in different ways. The A port keeps track of the source voltage on the VCCA pins. Any voltage between 1.4 V and 3.6 V can be used to power the VCCA pin. The B port tracks the voltage on the VCCB pin. Any energy between 1.65 V and 5.5 V can be used to power the VCCB pin. Two input supply pins let you translate between any of the 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V voltage nodes at low voltage. When the input for enabling output (OE) is low, all of the outlets are in a state called “high impedance” (Hi-Z). Use a pull-down resistor to connect OE to GND. This will maintain the Hi-Z state during power-up and power-down. The minimum number of resistors is set by how much current the driver can supply.

TXS0108EPWR Features

  • No direction-control signal is needed.
  • (VCCA, VCCB) 1.4 V to 3.6 V on port A and 1.65 V to 5.5 V on port B.
  • There is no need to sequence the power source; either VCCA or VCCB can be ramped first.
  • As per JESD 78, Class II, the latch-up performance is more than 100 mA.

● ESD Ratings

The TXS0108EPWR’s ESD (Electrostatic Discharge) ratings make sure that it can handle electrostatic discharge events and keep it from damage. These numbers show how much static electricity the IC can handle before it gets permanently damaged. In the device’s datasheet, you can find the TXS0108EPWR’s ESD ratings. These ratings tell you how to handle and protect the device safely during making, assembly, and use.

TXS0108EPWR Conditions for Recommended Use

The TXS0108EPWR will work reliably within its specified performance range if it is run under the suggested operating conditions. Most of the time, voltage levels, temperature ranges, and other important factors are part of these conditions. The suggested operating voltage range says what levels of power supply are okay for the device, making sure it works right. The temperature range shows the safe and effective temperatures at which the IC can work. By using the TXS0108EPWR in these ways, you can make sure it works well and lasts as long as possible.

Details about the temperature

Thermal information tells you about the device’s temperature needs and how it works. It takes into account things like thermal resistance, thermal conductance, and how much power is lost. The IC’s ability to get rid of heat is shown by its thermal resistance, and the link between temperature and power loss is shown by its thermal impedance. This information helps design and apply the right thermal management techniques to keep the TXS0108EPWR from overheating and keeping it working well. It is very important to make sure there is enough cooling or heat sinking, especially when the device is used at high ambient temperatures or in applications that use a lot of power.

Typical characteristics

● Give Voltage

The TXS0108EPWR usually works within a suggested supply voltage range, which makes sure that it works reliably and consistently. The typical voltage range shows the normal levels of voltage at which the gadget can be powered to work at its best.

● Logic Voltage Levels

The IC can translate voltages in both directions between different logic families. Typical characteristics define the logic voltage values for input and output signals. This makes sure that different logic domains can work together and communicate without problems.

● Propagation Delay

Propagation delay is the amount of time it takes for a signal to move from the input to the output of an IC. The average propagation delay under normal operating conditions is given by the typical characteristics. It helps measure how fast and responsive the IC is, so makers can build circuits that take into account any delays in signals.

● Performance of Voltage Conversion

Typical features include information about how well voltages are translated, such as voltage-level thresholds and the ability to change voltage levels. These specs show that the device can accurately and reliably translate voltage levels between different logic families, which is important for making sure that signals are correct and data is transferred correctly.

● Current Consumption

The typical current consumption specifications give an idea of how much power the gadget needs when it is working normally. This information helps with power budgeting and making sure the TXS0108EPWR has the right power source setup.

Suggestions for a Power Supply

Make sure that VCCA > VCCB at all times while the device is running. During the power-up process, the order of the power supplies won’t hurt the gadget, so either one can be turned on first. The input circuit for output-enable (OE) is set up so that it gets its power from VCCA. All outputs have high impedance when OE is low. To make sure that the outputs are in a high-impedance state when the power is turned on or off, the OE input pin must be connected to GND with a pull-down resistor that must not be switched on until VCCB and VCCA are both fully up and running and stable. How much power the driver can source determines the minimum value of the pull-down resistor to ground.

Measuring parameters

● Load Circuits

Load circuits give you a standard way to test and measure how well the TXS0108EPWR works under certain load situations. Most of the time, these circuits are made up of resistors, capacitors, and other parts that mimic the load conditions that the IC is likely to face in real life. The load circuits listed in the manual help make sure that voltage levels, the amount of current used, and the propagation delay are measured accurately and consistently.

● Voltage Waveforms

Voltage waveforms show what the electrical signals look like at different places in a circuit as it works. Usually, the manual for the TXS0108EPWR tells you how to test it and set it up so that you can measure voltage waveforms. This includes information about the features of the input and output signals, such as their amplitude, rise and fall times, and how they work with time. With these voltage patterns, designers and engineers can figure out how the IC’s signal integrity, voltage levels, and timing needs change when it is used in different ways.


The TXS0108EPWR from Texas Instruments is an 8-bit, bidirectional, non-inverting-level translator. It is made to translate voltages between different logic types. It has two power supply lines that can be set up. The A port follows VCCA (1.4 V to 3.6 V), and the B port follows VCCB (1.65 V to 5.5 V). The device doesn’t need a direction-control input, and according to JESD 78, Class II, it can latch up at more than 100 mA. It can be used for level translation on phones, tablets, desktop PCs, and cellphones.

The device works within the recommended voltage and temperature ranges, and it is advised to set up the power supply and pull-down resistor for the OE pin in the right way. The datasheet has information about load circuits for making accurate readings and voltage waveforms for figuring out what a signal is doing.
