Overview
The 74HC595BQ-Q100,115 is an 8-bit serial-in/serial or parallel-out shift register produced by Nexperia USA Inc. This integrated circuit features a storage register and 3-state outputs, making it versatile for various digital circuit applications. The device includes separate clocks for both the shift and storage registers, enabling precise control over data transfer. It also 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 when necessary.
