SN74HC4020NS

Counter Dividers Overview

The SN74HC4020NS is a 14-stage asynchronous binary ripple-carry counter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features an operating temperature range of -40°C to 85°C. The device advances on the negative-going edge of the clock pulse and resets to zero when the clear input goes high. It is housed in a 16-pin Small Outline Package (SO) with dimensions of 6.20 mm × 5.30 mm.

Counter Dividers Feature Summary

• Provides 14-stage binary counting functionality advancing on the negative-going edge of the clock pulse
• Features asynchronous reset capability that clears all outputs to low independently of the clock input
• Supports driving up to 10 LSTTL loads with low power consumption characteristics

Counter Dividers Applications

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

Counter Dividers Procurement Notes

Verify the specific ordering suffix NS corresponds to the 16-pin SOP package. Confirm RoHS compliance status as indicated in the manufacturer's documentation. Check current production status, as availability may vary between active and NRND classifications depending on the specific revision.

Counter Dividers Selection Notes

Select this component for designs requiring a 14-bit asynchronous counter in a surface-mount format. Ensure the application voltage remains within the 2 V to 6 V range. Consider the maximum clock frequency limitations at the chosen supply voltage when designing timing-critical paths.

Counter Dividers Part Context

This part belongs to the SNx4HC4020 family of 14-bit asynchronous binary counters from Texas Instruments. The family includes variants such as SN74HC4020D, SN74HC4020N, and SN74HC4020PW, which differ primarily in packaging options like SOIC, PDIP, and TSSOP while maintaining identical logical functionality.
