12-stage binary ripple counter
Rev. 6 — 8 June 2020
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
