74HC4040; 74HCT4040
12-stage binary ripple counter
Rev. 03 — 14 September 2005
Product data sheet
1. General description
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.
2. Features
■ Multiple package options
■ Complies with JEDEC standard no. 7A
■ ESD protection:
◆ HBM JESD22-A114-C exceeds 2000 V
◆ MM JESD22-A115-A exceeds 200 V
■ Specified from −40 °C to +85 °C and from −40 °C to +125 °C
3. Applications
■ Frequency dividing circuits
■ Time delay circuits
■ Control counters

VI = GND to VCC − 1.5 V
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.

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.
