74F398 Product details

Description

The ’F398 and ’F399 are the logical equivalents of a quad 2-input multiplexer feeding into four edge-triggered flipflops A common Select input determines which of the two 4-bit words is accepted The selected data enters the flipflops 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

Features

Y Y Y Y Select inputs from two data sources Fully positive edge-triggered operation Both true and complement outputs ’F398 Guaranteed 4000V minimum ESD protection ’F399 Commercial 74F398PC Military Package Number N20A Package.
