74HC/HCT4040; 12-stage binary ripple counter
Philips Semiconductors Product specification
12-stage binary ripple counter 74HC/HCT4040
FEATURES Output capability: standard ICC category: MSI
GENERAL DESCRIPTIONThe 74HC/HCT4040 are high-speed Si-gate CMOS
devices and are pin compatible with “4040” of the “4000B”
series. They are specified in compliance with JEDEC
standard no. 7A.
The 74HC/HCT4040 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.
APPLICATIONS Frequency dividing circuits Time delay circuits Control counters
QUICK REFERENCE DATAGND= 0 V; Tamb =25 °C; tr =tf= 6 ns
Notes CPD is used to determine the dynamic power dissipation (PD in μW): =CPD× VCC2×fi +∑ (CL× VCC2× fo) where:= input frequency in MHz= output frequency in MHz
∑ (CL× VCC2×fo)= sum of outputs= output load capacitance in pF
VCC= supply voltage in V For HC the condition is VI= GND to VCC
For HCT the condition is VI= GND to VCC− 1.5 V

Note to HCT typesThe value of additional quiescent supply current (ΔICC) for a unit load of 1 is given in the family specifications.
To determine ΔICC per input, multiply this value by the unit load coefficient shown in the table below.
