74HC4040; 74HCT4040

12-stage binary ripple counter

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.

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

Applications

  • Frequency dividing circuits
  • Time delay circuits
  • Control counters
