The CD74HC595SM96 is an 8-bit, serial-in/parallel-out shift register manufactured by Texas Instruments. It is a high-speed logic device with inputs and outputs capable of 2.7V to 5.5V operation. It is designed to be used in applications requiring operations such as parallel loading, serial output data, shifted input data, and data transfer between stages. The device has a built-in counter, which is used to keep track of data movement during shifting operations. The package comes with two 8-bit shift registers and a counter, allowing for a maximum output of 48 bits. The shift registers have common clock and storage registers, allowing for easy data transfer. This logic device is often used to simplify interfacing with multiple devices, as it allows for faster and more efficient data transmission.
