74F398 • 74F399

Quad 2-Port Register

General Description

Features

■ Select inputs from two data sources

■ Fully positive edge-triggered operation

■ Both true and complement outputs—74F398

The 74F398 and 74F399 are the logical equivalents 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-flops on the rising edge of the clock. The 74F399 is the

16-pin version of the 74F398, with only the Q outputs of the

flip-flops available.
