SN74AS163NG4

Counter Dividers Overview

The SN74AS163NG4 is a synchronous 4-bit binary counter from the Texas Instruments AS Logic Series. It features positive edge triggering and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a 16-pin Plastic Small Outline (PSOP) package with green plastic construction. It supports synchronous preset and synchronous clear functions, allowing for precise control over counting states without asynchronous interference.

Counter Dividers Feature Summary

• Synchronous 4-bit binary up-counter architecture
• Positive edge-triggered clock operation
• Synchronous preset and clear capabilities

Counter Dividers Applications

• Digital timing circuits requiring precise synchronization
• Frequency division networks in digital systems
• Event counting applications in industrial control

Counter Dividers Procurement Notes

Verify the specific suffix 'G4' against official Texas Instruments documentation to confirm compliance with RoHS directives and manufacturing standards. Ensure the component matches the exact PSOP-16 package dimensions and pinout configuration required by the design. Cross-reference the datasheet revision to validate electrical characteristics and operating temperature ranges before integration.

Counter Dividers Selection Notes

Select this component when high-speed performance is required alongside synchronous control features. The AS series offers faster propagation delays compared to standard TTL or HC logic families. Verify that the system power supply strictly maintains the 4.5 V to 5.5 V range to ensure reliable operation and prevent damage to the bipolar input structure.

Counter Dividers Part Context

This part belongs to the Texas Instruments SN74AS163 family of synchronous counters. It shares functional similarities with other 4-bit binary counters but distinguishes itself through the AS logic technology, which provides superior speed. The 'G4' suffix typically indicates environmental compliance and specific manufacturing lot attributes defined by the manufacturer.

Counter Dividers Replacement Considerations

Direct substitutes include SN74AS163NSR and SN74ALS163BNSRE4. Verify pin compatibility and electrical specifications before substitution. Note that ALS variants may have different switching speeds and drive strengths compared to the AS series.
