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 SD or CD prevents clocking and forces Q or Q HIGH, respectively.

Simultaneous LOW signals on SD and CD force both Q and Q HIGH.

Asynchronous Inputs:

LOW input to SD sets Q to HIGH level

LOW input to CD sets Q to LOW level

Clear and Set are independent of Clock

Simultaneous LOW on CD and SD

makes both Q and Q HIGH
