74VHC112
Dual J-K Flip-Flops with Preset and Clear
General Description
The VHC112 is an advanced high speed CMOS device
fabricated with silicon gate CMOS technology. It achieves
the high-speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissi-
pation.
The VHC112 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 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 dur-
ing the recommended setup and hold times relative to the
falling edge of the clock. The LOW signal on PR or CLR
prevents clocking and forces Q and Q HIGH, respectively.
Simultaneous LOW signals on PR and CLR force both Q
and Q HIGH.
An input protection circuit ensures that 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery backup. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
