CD74AC161M

Counter Dividers Overview

The CD74AC161M is a synchronous 4-bit binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 1.5 V to 5.5 V and supports counting in the up direction. The device features an asynchronous reset function and utilizes positive edge triggering for clock synchronization. It is housed in a 16-SOIC surface-mount package, suitable for industrial temperature ranges from -55°C to +125°C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with up-direction capability
• Asynchronous reset functionality for immediate state clearing
• Positive edge-triggered clock operation
• Wide operating voltage range supporting low-power applications

Counter Dividers Applications

• Digital frequency division circuits
• Sequential timing control systems
• Binary data storage and processing modules

Counter Dividers Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status as manufacturing processes may vary. Check for obsolescence notices or lifecycle changes before finalizing procurement plans to ensure long-term availability.

Counter Dividers Selection Notes

Select this component when a wide voltage range including sub-3V operation is required compared to standard 5V-only logic families. Ensure the design accommodates the synchronous nature of the counter and the specific pinout of the SOIC-16 package. Verify that the asynchronous reset meets system timing requirements.

Counter Dividers Part Context

This part belongs to the Texas Instruments 74AC logic family, known for high-speed CMOS performance. It serves as a fundamental building block for digital counters within the broader 74xx series ecosystem, offering compatibility with other AC-series logic components while providing enhanced speed over older HC variants.
