Detailed Description

The 74HC166 are high-speed Si-gate CMOS devicesand are pin compatible with low power Schottky TTL(LSTTL). The 74HC166 are 8-bit shift registers which have a fully synchronous serial or parallel data entry selected by an active LOW parallel enable (PE) input. When PE is LOW one set-up time prior to the LOW-to-HIGH clock transition, parallel data is entered into the register. When PE is HIGH, data is entered into the internal bit position Q0 from serial data input (Ds), and the remaining bits are shifted one place to the right (Q0 Q1 Q2, etc.) with each positive-going clock transition.This feature allows parallel-to-serial converter expansionby tying the Q7 output to the Ds input of the succeedingstage. The clock input is a gated-OR structure which allows one input to be used as an active LOW clock enable (CE) input. The pin assignment for the CP and CE inputs is arbitrary and can be reversed for layout convenience. The LOW-to-HIGH transition of input CE should only take place while CP is HIGH for predictable operation. A LOW on the master reset (MR) input overrides all other inputs and clears the register asynchronously, forcing all bit positions to a LOW state.

Features:
Synchronous parallel-to-serial applications
Synchronous serial data input for easy expansion
Clock enable for "do nothing" mode
Asynchronous master reset
