Dual JK Negative Edge-Triggered Flip-Flop
with Common Clocks and Clears
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
prevents clocking and forces Q or Q HIGH, respectively.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
