Download the TC74HC4040AFN datasheet PDF. This datasheet also covers the TC74HC4020AP variant, as both devices belong to the same cmos digital integrated circuit silicon monolithic 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) = 2~6 V.
  • Pin and function compatible with 4020B/4040B Note: xxxFN (JEDEC SOP) is not av.

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.
