SN74LS161ANG4

Counter Dividers Overview

The SN74LS161ANG4 is a 4-bit synchronous binary counter from the Texas Instruments 74LS series. It operates with a supply voltage of 4.75 V to 5.25 V and supports counting rates up to 25 MHz. The device features asynchronous reset, parallel load capability, and two count enable inputs. It is housed in a 16-pin DIP package and functions on positive edge triggering.

Counter Dividers Feature Summary

• Synchronous four-bit binary counting with positive edge clock triggering
• Asynchronous master reset for immediate output clearing
• Parallel data loading via dedicated input pins
• Carry output generation for cascading applications

Counter Dividers Applications

• Digital frequency division circuits
• Event counting systems
• Timing sequence generation
• Cascaded multi-stage counter designs

Counter Dividers Procurement Notes

Verify the G4 suffix indicates lead-free manufacturing compliant with RoHS standards. Confirm the 'AN' designation corresponds to the 16-pin PDIP package type. Ensure the component matches the specific 74LS logic family requirements for your circuit design before integration.

Counter Dividers Selection Notes

Select this component when a synchronous binary counter with parallel load and asynchronous reset is required. It is suitable for standard 5V logic environments. Consider package availability if surface mount options are preferred over through-hole DIP configurations.

Counter Dividers Part Context

This part belongs to the SN74LS161 family of integrated circuits manufactured by Texas Instruments. It is a variant within the broader 7400-series logic line, specifically designed for high-speed digital counting operations using Low-power Schottky technology.

Counter Dividers Replacement Considerations

Compatible substitutes include SN74LS161ADRE4 and SN74LS161ANSR. Verify pin compatibility and electrical specifications match before substitution.
