MM74HC393

Dual 4-Bit Binary Counter

as well as pin equivalent to the 74LS393. All inputs are pro-

tected from damage due to static discharge by diodes to

General Description

The MM74HC393 counter circuits contain independent rip-

ple carry counters and utilize advanced silicon-gate CMOS

technology. The MM74HC393 contains two 4-bit ripple

carry binary counters, which can be cascaded to create a

single divide-by-256 counter.

_CCand ground.

Features

■ Typical operating frequency: 50 MHz

Each of the two 4-bit counters is incremented on the HIGH-

to-LOW transition (negative edge) of the clock input, and

each has an independent clear input. When clear is set

HIGH all four bits of each counter are set to a low level.

This enables count truncation and allows the implementa-

tion of divide-by-N counter configurations.

■ Typical propagation delay: 13 ns (Ck to Q_A)

■ Wide operating supply voltage range: 2–6V

■ Low input current: <1 µA

■ Low quiescent supply current: 80 µA maximum (74HC

Series)

■ Fanout of 10 LS-TTL loads

Each of the counters outputs can drive 10 low power

Schottky TTL equivalent loads. This counter is functionally
