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

with Preset, Clear and Complementary Outputs

General Description

This device contains two independent positive-edge-trig-

gered D-type 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

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

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.

Function Table

Note 1: This configuration is nonstable; that is, it will not persist when either

the preset and/or clear inputs return to their inactive (HIGH) level.

LOW Logic Level

Positive-going transition of the clock.

Either LOW or HIGH Logic Level

HIGH Logic Level

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

established.
