SN74HC161NSR

Counter Dividers Overview

The SN74HC161NSR is a high-speed CMOS logic device manufactured by Texas Instruments, functioning as a 4-bit synchronous binary counter. It operates within a supply voltage range of 2V to 6V and supports clock frequencies up to 36 MHz. The component features an asynchronous reset input and positive-edge triggering for its flip-flops. Designed for surface-mount applications, it utilizes a 16-SOIC package with a width of 5.30mm. The device is rated for operation across a temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting architecture with positive-edge triggering
• Asynchronous reset capability for immediate state clearing
• High-speed CMOS technology supporting operation up to 36 MHz

Counter Dividers Applications

• Digital timing and sequencing circuits
• Frequency division networks
• Event counting systems

Counter Dividers Procurement Notes

Verify the specific suffix NSR indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Texas Instruments to ensure compatibility with standard 74HC logic families. Check datasheet revisions for any updates on electrical characteristics or recommended operating conditions prior to final design integration.

Counter Dividers Selection Notes

Select this component for designs requiring synchronous counting with a dedicated asynchronous reset function. Ensure the system voltage falls within the 2V to 6V range to maintain specified performance levels. Consider the SOIC-16 package dimensions for PCB layout constraints and verify thermal requirements against the -40°C to +85°C operational limit.

Counter Dividers Part Context

This part belongs to the Texas Instruments 74HC series of high-speed CMOS logic devices. The 74HC161 specifically provides a 4-bit binary count function. It is distinct from decade counters like the 74HC190 which support decimal counting. The 'NSR' designation typically denotes the SOIC package variant supplied in reel format for automated assembly processes.

Counter Dividers Replacement Considerations

Direct functional equivalents include other 74HC161 variants such as SN74HC161N or SN74HC161D, provided pinout and package compatibility are verified. Cross-reference with CD74HC161 series parts for similar specifications from the same manufacturer.
