1. Functional Description

•

Dual Binary Counter

2. General

The 74HC393D is a high speed CMOS 4-BIT BINARY COUNTER fabricated with silicon gate C2MOS technology.

It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power

dissipation.

It contains two independent counter circuits in one package, so that counting or frequency division of eight binary

bits can be achieved with one IC.

This device changes state on the negative going transition of the CK pulse. The counter can be reset to "0" (QA

to QD = "L") by a high at the CLR input regardless of other inputs.

All inputs are equipped with protection circuits against static discharge or transient excess voltage.

3. Features

(1)

Wide operating temperature range: Topr = -40 to 125 � (Note 1)

(2)

High speed: fMAX = 72 MHz (typ.) at VCC = 5 V

(3)

Low power dissipation: ICC = 4.0 µA (max) at Ta = 25 �

(4)

Balanced propagation delays: tPLH

≈ tPHL

(5)

Wide operating voltage range: VCC(opr) = 2.0 V to 6.0 V

Note 1: Operating Range spec of Topr = -40 � to 125 � is applicable only for the products which manufactured after

July 2020.
