Advance Information

Dual 4−Bit Binary Ripple

Counter

The MC74VHCT393A is an advanced high speed CMOS dual 4−bit

binary ripple counter fabricated with silicon gate CMOS technology. It

achieves high speed operation similar to equivalent Bipolar Schottky TTL

while maintaining CMOS low power dissipation.

MARKING DIAGRAMS

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.

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 VHC393.

The VHCT inputs are compatible with TTL levels. This device can be

used as a level converter for interfacing 3.3 V to 5.0 V because it has full 5

V CMOS level output swings.

The VHCT393A input structures provide protection when voltages

between 0 V and 5.5 V are applied, regardless of the supply voltage. The

output structures also provide protection when V = 0 V. These input and

output structures help prevent device destruction caused by supply

voltage—input/output voltage mismatch, battery backup, hot insertion, etc.

The internal circuit is composed of three stages, including a buffer

output which provides high noise immunity and stable output., The inputs

tolerate voltages up to 7 V, allowing the interface of 5 V systems to 3 V

systems.
