HEF4040B

12-stage binary ripple counter

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. Inputs are overvoltage tolerant to 15 V. This enables the device to be used in HIGH-to-LOW level shifting applications.

Features and benefits

  • Wide supply voltage range from 3.0 V to 15.0 V

  • CMOS low power dissipation

  • High noise immunity

  • Tolerant of slow clock rise and fall time

  • Fully static operation

  • 5 V, 10 V, and 15 V parametric ratings

  • Standardized symmetrical output characteristics

  • Complies with JEDEC standard JESD 13-B

  • ESD protection:
    • HBM JESD22-A114F exceeds 2000 V

    • MM JESD22-A115-B exceeds 200 V

  • Specified from -40 °C to +85 °C

Applications

  • Frequency dividing circuits

  • Time delay circuits

  • Control counters
