SN74AS74A - Dual Positive-Edge-Triggered D-Type Flip-Flops

Download the SN74AS74A datasheet PDF. This datasheet also covers the SN74ALS74A variant, as both devices belong to the same dual positive-edge-triggered d-type flip-flops family and are provided as variant models within a single manufacturer datasheet.

General Description

These devices contain two independent positive-edge-triggered D-type flip-flops.

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