Overview
The 74HCT595DB-Q100J, produced by 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 part of the 74HCT series, which operates at TTL logic levels. It is designed for a wide range of applications, including automotive, industrial, and consumer electronics, due to its robust performance and versatility.
The device features separate clocks for the shift and storage registers, allowing for flexible data transfer and output control. It includes a serial input (DS), a serial output (Q7S) for cascading, and an asynchronous reset input (MR). The output enable input (OE) allows the outputs to be set to a high-impedance OFF-state without affecting the register states.
