This two-bit non-inverting bus transmitter has two power rails that can be set separately. The A port can be used to follow the VCCA signal. The range of voltages that VCCA can accept is from 1.2 V to 3.6 V. The B port is set up to follow the signal from VCCB. VCCB can work with voltages as low as 1.2 V and as high as 3.6 V. This lets you translate at low voltage in both directions between any voltage values, such as 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V.
The SN74AVC2T245 was made so that two data lines can talk to each other at different times. Depending on the logic levels of the direction-control (DIR) input and the output-enable (OE), one or both of the output ports can be set to the B-port outputs, the A-port outputs, or the high-impedance mode.
When the device’s B-port outputs are active, data is sent from the A bus to the B bus. When the A-port outputs are active, data is sent from the B bus to the A bus. To keep ICC and ICCZ from getting too high, a logic HIGH or LOW signal must always be sent to the input circuits on both the A and B ports. The SN74AVC2T245’s control pins (DIR1, DIR2, and OE) get their power from VCCA. All of the requirements for Ioff-based partial power-down activities are met by this device.
When the power is turned off, the Ioff circuitry stops the outputs so that electricity doesn’t flow back through the gadget and damage it. If either VCC input is linked to GND, the VCC isolation function makes sure that both ports are in the high-impedance state. To maintain high-impedance during power-up and power-down, OE must be connected to VCC with a proper pull-up resistor. The minimum value of this resistor is determined by how much current the driver can sink.
The SN74AVC2T245 is a two-bit, two-supply, non-inverting, bidirectional voltage level translator. VCCA supports pins A and control pins (DIR and OE), and VCCB supports pins B. The I/O values that can be used with the A port range from 1.2 V to 3.6 V, and the same is true for the B port. When OE is set to low, a high on DIR lets data go from A to B, and a low on DIR lets data go from B to A. If OE is set to high, both A and B are in the high-impedance state. This device meets all the requirements for partial-power-down apps that use off output current (Ioff). The VCC isolation function makes sure that both ports are in a high-impedance state if either VCC input is at GND.
Whether you need voltage translation between nodes with low voltages like 1.2 V, 1.8 V, 2.5 V, or 3.3 V, both VCCA and VCCB can be provided at any voltage within this range. This high level of adaptability makes sure that it works well in a wide range of uses.
This part was made and tried carefully to meet the needs of partial-power-down applications, where power consumption needs to be carefully managed. The gadget’s off output current (Ioff) electronics keeps current from flowing backwards. In partial power-down mode, it protects reliably and makes better use of power by turning down the I/O output circuits. You can count on our device to give you the consistency and efficiency you need for your partial-power-down apps.
With the VCC isolation feature, the device guarantees a high level of protection and signal integrity. In the event that either VCCA or VCCB is at GND, both ports are automatically placed in a high-impedance state (IOZ). This crucial functionality eliminates the possibility of false logic levels being transmitted to either bus, ensuring reliable and accurate data transmission. Count on our device to maintain the integrity of your signals and prevent any unwanted disruptions or errors in your system.
The SN74AVC2T245 is a voltage level translator that can work with a wide range of voltage levels. For both VCCA and VCCB, it can handle voltages from 1.2 V to 3.6 V. The device has features like direction control and output allow control to make sure that it translates signals correctly. The action of the part is controlled by these control inputs. The table below shows how the part works in different control input states. The SN74AVC2T245 is a great choice for smooth voltage level translation in your application because it has a wide range of features and exact control.
The SN74AVC2T45 is a safe way to change the voltage level between two voltage domains. It makes it easy for IO voltage levels to change from one area to another. Bus A and bus B can be charged separately, which gives you more options for how to set them up. By using a direction pin, you have full control over the direction of data flow, which makes it easy for the two buses to talk to each other.
To make sure everything works right, it’s important to remember that any data ports that aren’t being used shouldn’t be left hanging. It is best to connect the inputs and outputs of ports that are not being used straight to ground. The SN74AVC2T45 is a great choice for voltage level shifting uses because it is easy to set up and works reliably.
You can use the following methods to figure out how long the SN74AVC16T45 is on:
In a bidirectional program, these enable times show how long it could take to get an output after the DIR bit is changed. For example, if the SN74AVC2T245 is sending data from bus A to bus B and then the DIR bit is changed, the B port of the device must be turned off before it can receive data from another source. Once the B port has been turned off, an input signal sent to it will show up on the A port after the transmission delay.
By using these methods, you can figure out the exact enable times for your application, making sure that the buses are timed and synchronized correctly.
In short, the SN74AVC2T245 gives voltage level translation applications a lot of freedom, reliable performance, and precise control. This device provides on all fronts, whether you need smooth communication in both directions, good power management, or accurate signal integrity. Choose the SN74AVC2T245 if you need to change the voltage level in a safe way and take advantage of its advanced features and wide range of functions.
