Features

■ ICC reduced by 50%

■ Outputs source/sink 24mA

■ ACT109 has TTL-compatible inputs

General Description

The AC/ACT109 consists of two high-speed completely independent transition clocked JK flip-flops. The clocking operation is independent of rise and fall times of the clock waveform. The JK design allows operation as a D-Type flip-flop (refer to AC/ACT74 data sheet) by connecting the J and K inputs together.

Asynchronous Inputs:

– LOW input to SD (Set) sets Q to HIGH level

– LOW input to CD (Clear) sets Q to LOW level

– Clear and Set are independent of clock

– Simultaneous LOW on CD and SD makes both Q and Q HIGH
