74HCT4020PW,118

Counter Dividers Overview

The Nexperia 74HCT4020PW,118 is a 14-stage binary ripple counter housed in a 16-lead TSSOP package (SOT403-1). It features an asynchronous master reset input and twelve buffered parallel outputs. The device operates on the HIGH-to-LOW transition of the clock input. Recommended supply voltage ranges from 4.5 V to 5.5 V. Operating temperature spans -40 °C to +125 °C.

Counter Dividers Feature Summary

• Provides 14-stage binary counting with an overriding asynchronous master reset function that clears all stages independently of the clock state.
• Accepts TTL-level input signals compatible with standard logic families while maintaining CMOS low power dissipation characteristics.
• Includes input clamp diodes to facilitate interfacing with voltages exceeding the supply rail using current limiting resistors.

Counter Dividers Applications

• Frequency dividing circuits
• Time delay circuits
• Control counters

Counter Dividers Selection Notes

Select this component when a 14-stage count is required within a 16-pin surface-mount footprint. Ensure the design utilizes a 5 V supply environment to match the HCT logic family specifications. Confirm that the application requires TTL-compatible input thresholds rather than standard CMOS levels.

Counter Dividers Part Context

This part belongs to the 74HCT series, which bridges HC logic performance with TTL input compatibility. The PW suffix indicates the TSSOP16 plastic thin shrink small outline package variant. It shares functional similarities with the 74HC4020 but differs in input voltage threshold requirements.

Counter Dividers Replacement Considerations

The 74HC4020PW serves as a logical alternative if CMOS input levels are acceptable. Other manufacturers may offer equivalent 14-stage counters in TSSOP16 packages, though pinouts and electrical characteristics must be verified against the official datasheet.

Counter Dividers FAQ

How does the master reset input affect the counter operation?

A HIGH signal on the master reset input overrides the clock input and forces all counter outputs LOW, clearing the counter immediately regardless of the clock state.

What type of clock transition triggers the count?

The counter advances its state on the HIGH-to-LOW transition of the clock pulse input.
