DM74LS112A

Dual Negative-Edge-Triggered Master-Slave J-K Flip-Flop

with Preset, Clear, and Complementary Outputs

General Description

This device contains two independent negative-edge-trig-

gered J-K flip-flops with complementary outputs. The J and

K data is processed by the flip-flop on the falling edge of

the clock pulse. The clock triggering occurs at a voltage

level and is not directly related to the transition time of the

falling edge of the clock pulse. Data on the J and K inputs

may be changed while the clock is HIGH or LOW without

affecting the outputs as long as the 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.

H = HIGH Logic Level

L = LOW Logic Level

X = Either LOW or HIGH Logic Level

↓ = Negative Going Edge of Pulse

= The output logic level before the indicated input conditions were

established.

Toggle = Each output changes to the complement of its previous level on

each falling edge of the clock pulse.

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

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