5474/DM5474/DM7474 Dual Positive-Edge-Triggered D Flip-Flops with Preset/Clear and Complementary Outputs
This document describes the 5474/DM5474/DM7474 Dual Positive-Edge-Triggered D Flip-Flops, which contain two independent flip-flops with complementary outputs. The device accepts information on the D input on the positive-going edge of the clock pulse and allows data changes while the clock is low or high, provided setup and hold times are met.
