Features & Applications

The HEF4040B is a 12-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and twelve fully buffered 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 CP. Each counter stage is a static toggle flip-flop.

The clock input is highly tolerant of slow rise and fall times due to its Schmitt trigger action. It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input. It is also suitable for use over the full industrial (40 C to +85 C) temperature range.


  • Tolerant of slow clock rise and fall time
  • Fully static operation
  • 5 V, 10 V, and 15 V parametric ratings
  • Standardized symmetrical output characteristics
  • Operates across the full industrial temperature range 40 C to +85 C
  • Complies with JEDEC standard JESD 13-B


  • Frequency dividing circuits
  • Time delay circuits
  • Control counters
