SN74LV161ADR

Counter Dividers Overview

The SN74LV161ADR is a low-voltage CMOS synchronous 4-bit binary up-counter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and supports LVTTL/TTL input compatibility with LVCMOS outputs. The device features asynchronous reset, synchronous preset, and positive-edge triggering. Packaged in a 16-pin SOIC surface-mount format, it functions as a single-element counter with unidirectional counting capability.

Counter Dividers Feature Summary

• Synchronous 4-bit binary up-counting operation
• Asynchronous reset and synchronous parallel load capabilities
• Wide operating voltage range from 2 V to 5.5 V
• Input compatibility with LVTTL and TTL logic levels

Counter Dividers Applications

• Digital timing and sequencing circuits
• Frequency division networks
• Event counting systems
• General-purpose digital counters

Counter Dividers Procurement Notes

Verify the specific package suffix 'A' corresponds to the required SOIC variant and confirm the 'D' suffix indicates reel packaging. Ensure the component meets RoHS3 compliance standards for your assembly process. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and current production status before procurement.

Counter Dividers Selection Notes

Select this component when a wide supply voltage range including 2 V operation is required. It is suitable for designs needing synchronous control with asynchronous reset functionality. Verify that the 16-pin SOIC footprint fits the PCB layout constraints. Confirm that the input logic levels match the system's LVTTL or TTL requirements for proper interface compatibility.

Counter Dividers Part Context

This part belongs to the Texas Instruments 74LV series of low-voltage CMOS logic devices. It is functionally related to other 74LV161 variants such as SN74LV161AD and SN74LV161APWRE4, differing primarily in package type and reel specifications. The series provides high-speed performance with low power consumption for general-purpose digital applications.

Counter Dividers Replacement Considerations

SN74LV161AD is a verified alternative offering identical logical functionality in a standard SOIC package.
