Overview
The 74HCT595BQ,115 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs, manufactured by Nexperia USA Inc. This device is part of the 74HCT logic family and is designed to operate within a supply voltage range of 4.5V to 5.5V. It features separate clocks for the shift and storage registers, enabling flexible data transfer and output control. The device includes a serial input (DS), a serial output (Q7S) for cascading, and an asynchronous reset input (MR). The outputs can be set to a high-impedance OFF-state using the output enable input (OE).
