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 dissipation.
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. Triggering 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 with-
out affecting 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. 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
voltage. This device can be used to interface 5V to 3V
systems and two supply systems such as battery
backup. This circuit prevents device destruction due to
mismatched supply and input voltages.
Ordering Information
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the
