74HC4040; 74HCT4040  
12-stage binary ripple counter  
Rev. 7 — 26 May 2021  
Product data sheet  
1. General description  
The 74HC4040; 74HCT4040 is a 12-stage binary ripple counter 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. Inputs include clamp diodes that enable the use of current limiting resistors to interface  
inputs to voltages in excess of VCC  
.
2. Features and benefits  
Wide supply voltage range from 2.0 V to 6.0 V  
CMOS low power dissipation  
High noise immunity  
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B  
Complies with JEDEC standards:  
JESD8C (2.7 V to 3.6 V)  
JESD7A (2.0 V to 6.0 V)  
Input levels:  
For 74HC4040: CMOS level  
For 74HCT4040: TTL level  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115-A exceeds 200 V  
Multiple package options  
Specified from -40 °C to +85 °C and from -40 °C to +125 °C  
3. Applications  
Frequency dividing circuits  
Time delay circuits  
Control counters
