SN74HC4040PWT

Counter Dividers Overview

The SN74HC4040PWT is a 12-stage asynchronous binary counter from the Texas Instruments 74HC series, housed in a 16-pin TSSOP package. It operates on 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 an asynchronous clear input that resets all outputs low and advances the count on high-to-low clock transitions. Key electrical characteristics include a maximum supply current of 80 µA, typical propagation delay of 12 ns, and output drive capabilities of ±4 mA at 5 V.

Counter Dividers Feature Summary

• Provides 12 external outputs for full stage visibility in asynchronous counting applications
• Features an asynchronous clear input to instantly reset all outputs to a low state
• Supports driving up to 10 LSTTL loads with standard CMOS inputs and outputs
• Designed for low power consumption with minimal supply current requirements

Counter Dividers Applications

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

Counter Dividers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific package type and marking against official datasheets. Check for RoHS compliance status and ensure handling precautions are followed due to electrostatic discharge sensitivity. Review the latest product life cycle status as availability may change.

Counter Dividers Selection Notes

Select this component when a 12-bit asynchronous binary counter is required within the HC logic family. Ensure the design accommodates the specified 2 V to 6 V supply voltage range. Verify that the TSSOP-16 package fits the board layout constraints. Consider the asynchronous clear functionality for system reset requirements.
