74HC4024

7-stage binary ripple counter

The 74HC4024 is a 7-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and seven fully buffered parallel outputs (Q0 to Q6). 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. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Features and benefits

  • Low-power dissipation

  • Complies with JEDEC standard no. 7A

  • CMOS input levels

  • ESD protection:
    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
  • Specified from -40 °C to +80 °C and from -40 °C to +125 °C.

Applications

  • Frequency dividing circuits

  • Time delay circuits.
