SN74HCS165PWR TI Shift Register | 16-TSSOP | 8-bit, Parallel-In/Serial-Out

Product Overview

The SN74HCS165PWR from Texas Instruments is an 8-bit parallel-in/serial-out shift register with Schmitt-trigger inputs, designed for high-speed data acquisition and serialization in digital systems. Housed in a compact 16-TSSOP package, it operates over a wide supply voltage range of 2V to 6V, making it suitable for both 3.3V and 5V logic systems. The device features an asynchronous parallel load capability, allowing simultaneous loading of 8 bits of data, which is then shifted out serially on the rising edge of the clock. With a typical propagation delay of 12 ns at 5V, it supports clock frequencies up to 100 MHz, enabling high-speed data transfer. The Schmitt-trigger inputs provide noise immunity and slow input signal conditioning, enhancing reliability in noisy environments.
