TC74HC4020AP/AF/AFN TC74HC4040AP/AF/AFN TC74HC4020AP/AF/AFN 14-STAGE BINARY COUNTER TC74HC4040AP/AF/AFN 12-STAGE BINARY COUNTER The TC74HC4020A/TC74HC4040A are high speed CMOS BINARY COUNTER/DIVIDERs fabricated with silicon gate CMOS technology. They achieve the high speed operation similar to 16 equivalent LSTTL while maintaining the CMOS dissipation. 1 The TC74HC4020A is a 14-STAGE BINARY P(DIP16-P300A) COUNTER, and the TC74HC4040A is a 12-STAGE BINARY COUNTER. Setting CLEAR to high resets the counter to low. 16 16 A negative transition on the CLOCK input brings one increment into the counter. ; 1 1 The TC74HC4020A provides 12 divided outputs: 1st stage and stage 4 thru stage 14. At Q14, a 1/16384 divided F(SOP16-P-300) FN(SOL16-P~180) 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.
