Dual Binary Counter

The TC74HC393A is a high speed CMOS 4-BIT BINARY

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.

Features

• Output drive capability: 10 LSTTL loads

•

• Pin and function compatible with 74LS393

Pin Assignment

Note: xxxFN (JEDEC SOP) is not available in

Japan.
