SN74ACT74 Datasheet (Texas Instruments) - DUAL POSITIVE-EDGE-TRIGGERED D-TYPE FLIP-FLOPS

SN74ACT74, DUAL POSITIVE-EDGE-TRIGGERED D-TYPE FLIP-FLOPS

ordering information NC * No internal connection The ’ACT74 dual positive-edge-triggered devices are D-type flip-flops.

A low level at the preset (PRE) or clear (CLR) input sets or resets the outputs, regardless of the levels of the other inputs.

When PRE and CLR are inactive (high), data
