74F114

Dual JK Negative Edge-Triggered Flip-Flop

with Common Clocks and Clears

Simultaneous LOW signals on S_Dand C_Dforce both Q and

Q HIGH.

General Description

The 74F114 contains two high-speed JK flip-flops with

common Clock and Clear inputs. Synchronous state

changes are initiated by the falling edge of the clock. Trig-

gering 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 affect-

ing the flip-flop, provided that they are in the desired state

during the recommended setup and hold times relative to

the falling edge of the clock. A LOW signal on S_Dor C_D

Asynchronous Inputs:

LOW input to S_Dsets Q to HIGH level

LOW input to C_Dsets Q to LOW level

Clear and Set are independent of Clock

Simultaneous LOW on C_Dand S_D

makes both Q and Q HIGH

prevents clocking and forces Q or Q HIGH, respectively.
