74F112
Dual JK Negative Edge-Triggered Flip-Flop
General Description
The 74F112 contains two independent, high-speed JK flip-
flops with Direct Set 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
