54F109DMQB Datasheet – Dual JK, Flip-Flop ( PDF )

Part Number: 54F109DMQB

Function: Dual JK (Note Overbar Over the K) Positive Edge-Triggered Flip-Flop

Package: DIP 16 Pin Type

Manufacturer: National ->Texas Instruments


54F109DMQB datasheet



The 54F109DMQB 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 flip-flop (refer to ’F74 data sheet) by connecting the J and K inputs.

Asynchronous Inputs :

(1) LOW input to SD sets Q to HIGH level

(2) LOW input to CD sets Q to LOW level

(3) Clear and Set are independent of clock

(4) Simultaneous LOW on CD and SD makes both Q and Q HIGH
