74HC166; 74HCT166

8-bit parallel-in/serial out shift register

Rev. 5 — 9 August 2021

Product data sheet

1. General description

The 74HC166; 74HCT166 is an 8-bit serial or parallel-in/serial-out shift register. The device

features a serial data input (DS), eight parallel data inputs (D0 to D7) and a serial output (Q7).

When the parallel enable input (PE) is LOW, the data from D0 to D7 is loaded into the shift register

on the next LOW-to-HIGH transition of the clock input (CP). When PE is HIGH, data enters the

is LOW data is shifted on the LOW-to-HIGH transitions of CP. A HIGH on CE disables the CP input.

Inputs include clamp diodes which enable the use of current limiting resistors to interface inputs to

voltages in excess of V_CC
