12-Stage Binary

Counter

The TC74HC4020A/TC74HC4040A are high speed CMOS

BINARY COUNTER/DIVIDERs fabricated with silicon gate

They achieve the high speed operetion similar to equivalent

LSTTL while maintaining the CMOS dissipation.

The TC74HC4020A is a 14-STAGE BINARY COUNTER, and

the TC74HC4040A is a 12-STAGE BINARY COUNTER.

Setting CLR to high resets the counter to low.

A negative transition on the CK input brings one increment

into the counter.

The TC74HC4020A provides 12 divided outputs: 1’st stage and

stage 4 thru stage 14. At Q14, a 1/16384 divided frequency will

be output.

The TC74HC4040A provides all divided output stages, and at

Q12, a 1/4096 divided frequency will be output.

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 4020B/4040B

Note: xxxFN (JEDEC SOP) is not available in

Japan.
