The 74HC4040; 74HCT4040 are high-speed Si-gate CMOS devices and are pin

compatible with the HEF4040B series. They are specified in compliance with JEDEC

standard no. 7A.

The 74HC4040; 74HCT4040 are 12-stage binary ripple counters with a clock input (CP),

an overriding asynchronous master reset input (MR) and twelve parallel outputs (Q0 to

Q11). The counter advances on the HIGH-to-LOW transition of CP.

A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the

state of CP.

Each counter stage is a static toggle flip-flop

1. CPD is used to determine the dynamic power dissipation (PD in μW):

PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where:

fi = input frequency in MHz

fo = output frequency in MHz

∑ (CL × VCC2 × fo) = sum of outputs

CL = output load capacitance in pF

VCC = supply voltage in V

2. For HC the condition is VI = GND to VCC

For HCT the condition is VI = GND to VCC − 1.5 V
