TC74HC4020AP, TC74HC4040AP 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 voltage.

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
