54F398 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 Select inputs from two data sources Y Fully positive edge-triggered operation Y Both true and complement outputs ’F398 Y Guaranteed 4000V minimum ESD protection ’F399 Commercial 74F398PC 74F398SC (Note 1) 74F399PC 74F399SC (Note 1) 74F399SJ (Note 1) Military 54F398DM (Note 2) 54F398FM (Note 2) 54F398LM (Note 2) 54F399DM (Note 2) 54F399FM (Note 2) 54F399LM (Note 2) Package Number N20A J20A M20B W20A E20A N20A J20A M20B M20D W20A E20A Package.
