General Description

The VHC393 is an advanced high speed CMOS 4-bit Binary Counter 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. It contains two independent counter circuits in one package, so that counting or frequency division of 8 binary bits can be achieved with one IC.

Features

■ High Speed: fMAX 170 MHz (typ) at TA 25°C

■ Low power dissipation: ICC = 4 μA (max) at TA 25°C

■ High noise immunity: VNIH = VNIL = 28 VCC (min)

■ Power down protection is provided on all inputs

■ Pin and function compatible with 74HC393
