Overview
The 74AHC595PW-Q100,11 from Nexperia USA Inc. is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. This device is designed to operate in a wide range of applications, including automotive, industrial, and consumer electronics. It features separate clocks for the shift and storage registers, enabling flexible data transfer and storage. The device includes a serial input (DS) and a serial output (Q7S) for cascading, as well as an asynchronous reset MR input. The output enable input (OE) controls the output state, allowing the outputs to be in a high-impedance OFF-state when OE is HIGH.
