Shift registers are a form of digital integrated circuit that can store and shift out many bits of data simultaneously. They’re frequently used to increase the number of digital outputs on a microcontroller or other digital device, and they can be cascaded to control even more outputs. The MC74HC595ADR2G is a high-speed 8-bit shift register with a popular serial-in, parallel-out (SIPO) feature.

The MC74HC595ADR2G is a popular choice for managing multiple digital outputs due to numerous significant features. These features include a wide supply voltage range (2V to 6V), low power consumption (4.5mA average at 5V), and a 3-state output. It also features a Schmitt-trigger input, which aids in noise reduction and ensures consistent operation. This post will cover the MC74HC595ADR2G in detail, including electrical properties and uses.

MC74HC595ADR2G Description

An eight-bit shift register and an eight-bit D-type latch with three-state parallel outputs make up the MC74HC595A. The shift register inputs and outputs serial data in a single stream. Data is simultaneously fed from the shift register to the 8-bit latch. The shift register’s and latch’s clock inputs are distinct. Additionally, this device has an asynchronous shift register reset. CMOS MPUs and MCUs immediately communicate with the HC595A via the SPI serial data port.
