74VHC112

Dual J-K Flip-Flops with Preset and Clear

Simultaneous LOW signals on PR and CLR force both Q

and Q HIGH.

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.

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.

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.

Features

■ High speed: f_MAX= 200 MHz (typ) at V_CC= 5.0V

■ Low power dissipation: I_CC= 2 µA (max) at T_A= 25°C

■ High noise immunity: V_NIH= V_NIL= 28% V_CC(min)

■ Power down protection is provided on all inputs

■ Pin and function compatible with 74HC112
