age. This device can be used to interface 5V to 3V systems

and two supply systems such as battery back up. This cir-

cuit prevents device destruction due to mismatched supply

and input voltages.

General Description

The VHC393 is an advanced high speed CMOS 4-bit

Binary Counter fabricated with silicon gate CMOS technol-

ogy. It achieves the high speed operation similar to equiva-

lent Bipolar Schottky TTL while maintaining the CMOS low

power dissipation. It contains two independent counter cir-

cuits in one package, so that counting or frequency division

of 8 binary bits can be achieved with one IC. This device

changes state on the negative going transition of the

Features

■ High Speed: f_MAX= 170 MHz (typ) at T_A= 25°C

■ Low power dissipation: I_CC= 4 µA (max) at T_A= 25°C

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

CLOCK pulse. The counter can be reset to “0” (Q₀–Q₃

■ Power down protection is provided on all inputs

■ Pin and function compatible with 74HC393

“L”) by a HIGH at the CLEAR input regardless of other

inputs.

An input protection circuit ensures that 0V to 7V can be

applied to the input pins without regard to the supply volt-
