54F/74F398 54F/74F399

Quad 2-Port Register

General Description

Features

Select inputs from two data sources

The ’F398 and ’F399 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 ’F399 is the 16-pin

version of the ’F398, with only the Q outputs of the flip-flops

available.

Fully positive edge-triggered operation

Both true and complement outputsÐ’F398

Guaranteed 4000V minimum ESD protectionÐ’F399
