SN74HC4020PWT

Counter Dividers Overview

The SN74HC4020PWT is a 14-stage asynchronous binary ripple counter manufactured by Texas Instruments. It advances on the negative-going edge of the clock pulse and resets to zero when the clear input goes high, independent of the clock. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature from -40°C to 85°C. It features low power consumption with a maximum ICC of 80 µA and typical propagation delay of 12 ns. The component is housed in a 16-pin TSSOP package.

Counter Dividers Feature Summary

• Provides 14-stage binary counting functionality advancing on negative clock edges
• Features an overriding asynchronous master reset input that clears all outputs independently of the clock signal
• Designed for wide operating voltage ranges compatible with standard logic families

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation for digital clocks
• Event counting systems

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'PWT' against the manufacturer's current Package Option Addendum to confirm availability status. The datasheet indicates this specific tape-and-reel variant may be obsolete; ensure the active equivalent SN74HC4020PWR is selected if production continuity is required. Confirm RoHS compliance and moisture sensitivity levels prior to procurement.

Counter Dividers Selection Notes

Select this component for designs requiring a 14-bit asynchronous counter with a single DFN or TSSOP footprint. Ensure the application circuit provides adequate bypass capacitance near the VCC terminal to prevent power disturbances. Verify that the clock signal transition times meet the specified limits for the chosen supply voltage to guarantee reliable operation.

Counter Dividers Part Context

This part belongs to the SNx4HC4020 family of 14-bit asynchronous binary counters. It shares functional characteristics with other variants such as SN74HC4020D and SN74HC4020N, differing primarily in packaging and manufacturing status. The HC series denotes high-speed CMOS technology, offering improved speed over legacy counterparts while maintaining low power consumption.
