74AC399 - Quad 2-Port Register

This page provides the datasheet information for the 74AC399, a member of the 74AC Quad 2-Port Register family.

Datasheet Summary

Description

The AC/ACT399 is the logical equivalent of a quad 2-input multiplexer feeding into four edge-triggered flip-flops.

A common Select input determines which of the two 4-bit words is accepted.

The selected data enters the flip-flop on the rising edge of the clock.

Features
