5474/DM5474/DM7474

Dual Positive-Edge-Triggered D Flip-Flops

with Preset, Clear and Complementary Outputs

General Description

This device contains two independent positive-edge-trig-

gered D flip-flops with complementary outputs. The informa-

tion on the D input is accepted by the flip-flops on the posi-

tive going edge of the clock pulse. The triggering occurs at a

voltage level and is not directly related to the transition time

of the rising edge of the clock. The data on the D input may

be changed while the clock is low or high without affecting

the outputs as long as the data setup and hold times are not

violated. A low logic level on the preset or clear inputs will

set or reset the outputs regardless of the logic levels of the

other inputs.

Features

Alternate Military/Aerospace device (5474) is available.

Contact a National Semiconductor Sales Office/Distrib-

utor for specifications.

High Logic Level

Either Low or High Logic Level

Low Logic Level

Positive-going transition of the clock.

This configuration is nonstable; that is, it will not persist when either the preset and/or clear

inputs return to their inactive (high) level.

The output logic level of Q before the indicated input conditions were established.
