Overview
The 74LVC595APW112, 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 designed for versatile use in digital circuits, allowing for both serial and parallel data output. It features separate clocks for the shift and storage registers, enabling precise control over data transfer. The device 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, without affecting the register states.
