Overview
The 74HC595D-Q100, 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 to meet the stringent requirements of automotive and industrial applications, having been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1). It operates over a wide temperature range from -40 °C to +125 °C and features separate clocks for both the shift and storage registers. The device includes a serial input (DS), a serial output (Q7S) for cascading, and an asynchronous reset MR input. The output enable input (OE) allows the outputs to be set to a high-impedance OFF-state when HIGH.
