SN74HC161NS

Counter Dividers Overview

The SN74HC161NS is a synchronous 4-bit binary counter manufactured by Texas Instruments in the 74HC series. It features an asynchronous reset and operates on positive-edge triggering. The device supports a supply voltage range of 2 V to 6 V and functions within an operating temperature range of -40°C to +85°C. It is housed in a 16-SOIC package with a maximum clock frequency of 36 MHz.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with positive-edge triggering
• Asynchronous reset capability for immediate state clearing
• High-speed CMOS logic construction for low power consumption

Counter Dividers Applications

• Digital timing sequences
• Frequency division circuits
• Event counters

Counter Dividers Procurement Notes

Verify the specific suffix 'NS' corresponds to the 16-SOIC surface-mount package variant when sourcing. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the selected distributor provides genuine Texas Instruments products to avoid counterfeit risks associated with legacy logic families.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with an asynchronous reset is required in a surface-mount design. The 74HC series offers compatibility with standard 5V logic systems while supporting lower voltages down to 2V. Consider the SOIC-16 footprint constraints and thermal performance requirements for your PCB layout.

Counter Dividers Part Context

This part belongs to the Texas Instruments 74HC family of high-speed CMOS logic devices. The 74HC161 specifically denotes a 4-bit synchronous counter with parallel load capabilities, distinct from asynchronous counter variants. The 'NS' suffix identifies the specific plastic small-outline package type used for surface-mount technology applications.
