Shift Registers

8-bit shift registerparallel loadSchmitt triggerTSSOP-162 V to 6 V

SN74HCS166PWR is a 16-pin TSSOP 8-bit parallel-load shift register operating from 2 V to 6 V, with Schmitt-trigger inputs and asynchronous active-low clear.

Best for

  • Microcontroller input expansion
  • 8-bit digital data storage
  • Slow or noisy digital input signals

Avoid if

  • A communication-interface I/O expander is required
  • Supply voltage is outside 2 V to 6 V

Check before use

  • Assert CLR during initialization if a known zero state is required
  • Keep unused inputs at a defined logic level
  • Observe clock, setup, output-current, and capacitive-load limits
