54AC11112 Datasheet DUAL J-K NEGATIVE-EDGE-TRIGGERED FLIP-FLOPS

Manufacturer: Texas Instruments

General Description

1CLK 1CLR NC V CC 2CLR These devices contain two independent J-K negative-edge-triggered flip-flops.

A low level at the preset (PRE) or clear (CLR) inputs sets or resets the outputs regardless of the levels of the other inputs.

When preset and clear are inactive (high), data at the J and K inputs meeting the setup time requirements are transferred to the outputs on the negative-going edge of the clock pulse.
