Overview

TC74HC4020,4040AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC4020AP, TC74HC4020AF TC74HC4040AP, TC74HC4040AF TC74HC4020AP/AF TC74HC4040AP/AF 14-Stage Binary Counter 12-Stage Binary Counter The TC74HC4020A/TC74HC4040A are high speed CMOS BINARY COUNTER/DIVIDERs fabricated with silicon gate C2MOS technology.
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 vo...
