74F166 Datasheet 8-bit Bidirectional Universal Shift Register

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS 74F166 8-bit bidirectional universal shift register Product specification IC15 Data Handbook 1991 Feb 14 Philips Semiconductors Philips Semiconductors Product specification 8-bit bidirectional.

General Description

The 74F166 is a high speed 8–bit shift register that has fully synchronous serial parallel data entry selected by an active low parallel enable (PE) input.

When the PE is low one setup time before the low–to–high clock transition, parallel data is entered into the register.

When PE is high, data is entered into 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.

Key Features

  • High impedance NPN base inputs for reduced loading.
  • (20µA in high and low states) Synchronous parallel to serial.
