Download the TC74HC4040AF datasheet PDF. This datasheet also covers the TC74HC4020AP variant, as both devices belong to the same 12-stage binary counter family and are provided as variant models within a single manufacturer datasheet.

Key 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 mA (min).
  • Balanced propagation delays: tpLH ∼.
  • tpHL.
  • Wide operating voltage range: VCC (opr) = 2 to 6 V.

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.
