SN74HC4040NSRE4

Counter Dividers Overview

The SN74HC4040NSRE4 is a 12-stage asynchronous binary counter from the Texas Instruments SN74HC4040 series. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40°C to 85°C. The device features a maximum clock frequency of 33 MHz at 6 V and typical propagation delays of 12 ns. It utilizes a 16-pin Small Outline (SO) package with negative edge-triggered counting and asynchronous clear functionality.

Counter Dividers Feature Summary

• Provides 12 external output stages for asynchronous binary counting
• Features asynchronous clear input that resets all outputs to low state
• Supports wide operating voltage range from 2 V to 6 V
• Capable of driving up to 10 LSTTL loads

Counter Dividers Applications

• Time-delay circuits
• Counter controls
• Frequency-dividing circuits

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'RE4' against the latest TI Package Option Addendum to confirm active production status, lead finish specifications, and moisture sensitivity level ratings. Ensure compatibility with RoHS requirements and check for any recent documentation updates or revision history changes affecting the component's electrical characteristics or packaging details.

Counter Dividers Selection Notes

Select this component when a 12-bit asynchronous binary counter is required with external access to all stage outputs. It is suitable for designs needing operation across a 2 V to 6 V supply range and temperatures down to -40°C. Consider the 16-pin SO package dimensions and thermal resistance values if board space or heat dissipation are critical constraints in the application layout.

Counter Dividers Part Context

This part belongs to the SNx4HC4040 family of 12-bit asynchronous binary counters manufactured by Texas Instruments. The HC logic series offers CMOS performance with standard TTL-compatible inputs. The device is distinct from synchronous counters like the SN74HC163 and other bit-counters such as the SN74HC4020 or SN74HC4060 within the same product portfolio.

Counter Dividers Replacement Considerations

Direct functional equivalents include SN74HC4040D, SN74HC4040DR, and SN74HC4040DBR. Verify pinout compatibility and package dimensions before substitution.
