74HCT4020BQ,115

Counter Dividers Overview

The Nexperia 74HCT4020BQ,115 is a 14-stage binary ripple counter in the 74HCT logic family. It features a clock input (CP), an overriding asynchronous master reset input (MR), and 12 buffered parallel outputs (Q0, Q3 to Q13). The counter advances on the HIGH-to-LOW transition of CP. Each stage utilizes a static toggle flip-flop with inputs including clamp diodes for voltage interfacing. It operates within a supply voltage range of 4.5 V to 5.5 V, supports a maximum frequency of 47 MHz at 4.5 V, and functions across temperatures from -40 °C to +125 °C. The component is housed in a DHVQFN16 package.

Counter Dividers Feature Summary

• Provides 14-stage binary counting capability with 12 buffered parallel outputs
• Features an overriding asynchronous master reset input that clears all stages independently of the clock state
• Includes input clamp diodes to enable current limiting resistor usage for voltages exceeding VCC
• Delivers high noise immunity and robust latch-up performance compliant with JESD 78 Class II Level B

Counter Dividers Applications

• Frequency dividing circuits
• Time delay circuits
• Control counters

Counter Dividers Selection Notes

Select this part when a 14-bit binary count is required with TTL-compatible input levels. The HCT variant ensures compatibility with standard TTL logic families while maintaining CMOS low power dissipation characteristics. Ensure the design accommodates the DHVQFN16 package dimensions and thermal requirements for the intended operating environment.

Counter Dividers Part Context

This component belongs to the Nexperia 74HCT4020 series, which includes variants in SO16, TSSOP16, and DHVQFN16 packages. The 74HCT designation indicates Transistor-Transistor Logic compatible input levels, distinguishing it from the HC series which uses CMOS levels. All variants share identical functional specifications and timing characteristics as defined in the product data sheet.

Counter Dividers Replacement Considerations

Equivalent parts include other manufacturers' 74HCT4020 devices in DHVQFN16 or equivalent leadless packages. Verify pinout compatibility and electrical parameters against the original datasheet before substitution.
