74VHC393

Dual 4-Bit Binary Counter

Features

General Description

■ High Speed: f

= 170MHz (Typ.) at T = 25°C

The VHC393 is an advanced high speed CMOS 4-bit

Binary Counter fabricated with silicon gate CMOS tech-

nology. It achieves the high speed operation similar to

equivalent Bipolar Schottky TTL while maintaining the

CMOS low power dissipation. It contains two indepen-

dent counter circuits 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 CLOCK pulse. The counter can be reset

MAX

■ Low power dissipation: I = 4µA (Max.) at T = 25°C

■ High noise immunity: V

= V

= 28% V (Min.)

NIH

NIL CC

■ Power down protection is provided on all inputs

■ Pin and function compatible with 74HC393

to “0” (Q –Q = “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

voltage. This device can be used to interface 5V to 3V

systems and two supply systems such as battery back

up. This circuit prevents device destruction due to mis-

matched supply and input voltages.
