SN74AS163NSR

Counter Dividers Overview

The SN74AS163NSR is a synchronous 4-bit binary counter from the Texas Instruments AS Series. It features positive edge triggering and operates within a standard 5V logic environment, typically between 4.5V and 5.5V. The device is housed in a 16-pin Green Plastic Small Outline (SOP) package with RoHS compliance. Key functional attributes include synchronous preset capability, synchronous clear, and ripple clock outputs for cascading applications.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting architecture with positive edge triggering
• Integrated synchronous preset and synchronous clear control inputs
• Dedicated ripple clock output terminals to facilitate multi-stage cascading

Counter Dividers Applications

• Digital timing sequence generation circuits
• Frequency division and pulse counting modules
• Cascaded digital system expansion designs

Counter Dividers Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and environmental compliance status. Ensure the component matches the required logic family specifications for your circuit design before procurement.

Counter Dividers Selection Notes

Select this component when high-speed switching performance is required compared to standard TTL or HC families. Consider the SOP-16 surface mount footprint for automated assembly processes and verify voltage compatibility with the target system power supply.

Counter Dividers Part Context

This part belongs to the Texas Instruments SN74AS series, representing Advanced Schottky technology. It serves as a high-performance alternative to older logic families, offering improved speed while maintaining standard pinouts compatible with existing 74-series designs.

Counter Dividers Replacement Considerations

Check for SN74AS163N or SN74AS163NS variants for through-hole alternatives. Verify SN74ALS163 equivalents if lower power consumption is prioritized over switching speed.
