TC74HC4020,4040AP/AF/AFN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC4020AP,TC74HC4020AF,TC74HC4020AFN TC74HC4040AP,TC74HC4040AF,TC74HC4040AFN 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 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. Features - High speed: fmax = 73 MHz (typ.) at VCC = 5 V - Low power dissipation: ICC = 4 μA (max) at Ta = 25°C - High noise immunity: VNIH = VNIL = 28% VCC (min) - Output drive capability: 10 LSTTL loads - Symmetrical output impedance: |IOH| = IOL = 4 m A (min) - Balanced propagation delays: tp LH ∼- tp HL - Wide operating voltage range: VCC (opr) = 2~6 V - Pin and function patible with 4020B/4040B Note: xxx FN (JEDEC SOP) is not available in Japan.
