5474 - Dual Positive-Edge-Triggered Flip-Flops

Description

This device contains two independent positive-edge-triggered D flip-flops with complementary outputs The information on the D input is accepted by the flip-flops on the positive going edge of the clock pulse The triggering occurs at a voltage level and is not directly related to the transition time
