SEMICONDUCTOR TECHNICAL DATA

J SUFFIX

CERAMIC PACKAGE

CASE 632–08

High–Performance Silicon–Gate CMOS

The MC54/74HC393A is identical in pinout to the LS393. The device

inputs are compatible with standard CMOS outputs; with pullup resistors,

they are compatible with LSTTL outputs.

This device consists of two independent 4–bit binary ripple counters with

parallel outputs from each counter stage. A ÷ 256 counter can be obtained

by cascading the two binary counters.

N SUFFIX

PLASTIC PACKAGE

CASE 646–06

Internal flip–flops are triggered by high–to–low transitions of the clock

input. Reset for the counters is asynchronous and active–high. State

changes of the Q outputs do not occur simultaneously because of internal

ripple delays. Therefore, decoded output signals are subject to decoding

spikes and should not be used as clocks or as strobes except when gated

with the Clock of the HC393A.
