DUAL JK NEGATIVE

EDGE-TRIGGERED FLIP-FLOP

The MC74F112 contains two independent, high-speed JK flip-flops with Di-

rect Set and Clear inputs. Synchronous state changes are initiated by the fal-

ling edge of the clock. Triggering occurs at a voltage level of the clock and is

not directly related to the transition time. The J and K inputs can change when

the clock is in either state without affecting the flip-flop, provided that they are

in the desired state during the recommended setup and hold times relative to

thefalling edge of the clock. A LOW signal on S or C prevents clocking and

forces Q or Q HIGH, respectively. Simultaneous LOW signals on S and C

force both Q and Q HIGH.

Asynchronous Inputs:

LOW Input to S sets Q to HIGH level

LOGIC SYMBOL

LOW Input to C sets Q to LOW level

Clear and Set are independent of clock

Simultaneous LOW on C and S makes both Q and Q HIGH

H = HIGH Voltage Level

L = LOW Voltage Level

= Bit time before clock pulse

+ 1 = Bit time after clock pulse
