74AC399 • 74ACT399

Quad 2-Port Register

General Description

Features

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.

■ I_CCreduced by 50%

■ Select inputs from two data sources

■ Fully positive edge-triggered operation

■ Outputs source/sink 24 mA

■ AC/ACT399 has TTL-compatible inputs
