Quad 2-Port Register

General Description

Features

The 74F399 is the logical equivalent of a quad 2-input mul-

tiplexer feeding into four edge-triggered flip-flops. A com-

mon Select input determines which of the two 4-bit words is

accepted. The selected data enters the flip-flops on the ris-

ing edge of the clock.

■ Select inputs from two data sources

■ Fully positive edge-triggered operation
