MM74HC393

Dual 4-Bit Binary Counter

General Description

Features

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.

■ Typical operating frequency: 50 MHz

■ 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)

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.

■ Fanout of 10 LS-TTL loads

Each of the counters outputs can drive 10 low power

Schottky TTL equivalent loads. This counter is functionally

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

tected from damage due to static discharge by diodes to

V_CCand ground.
