SN74S163N3

Counter Dividers Overview

The SN74S163N3 is a synchronous 4-bit binary counter belonging to the Texas Instruments SN54/74S series. It features positive-edge triggering and operates within a supply voltage range of 4.75 V to 5.25 V. The device includes synchronous clear and parallel data load capabilities, along with ripple clock outputs for cascading applications. It is housed in a standard 16-pin dual in-line package (DIP) suitable for through-hole mounting.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting architecture with positive-edge clock triggering
• Parallel data loading capability for direct preset input values
• Synchronous clear function that resets all outputs simultaneously upon command
• Ripple clock outputs provided to facilitate multi-stage counter cascading

Counter Dividers Applications

• Digital timing sequences and event counters
• Frequency division circuits
• Cascaded multi-digit counting systems
• Pulse generation logic

Counter Dividers Procurement Notes

Verify the specific suffix 'N3' against current manufacturer documentation, as it may indicate a legacy or restricted variant. Confirm RoHS compliance status and availability through authorized distributors, as older S-series components may have limited production runs or require cross-referencing with equivalent active parts.

Counter Dividers Selection Notes

Select this component when high-speed synchronous counting is required using Schottky TTL technology. Ensure the design supports the 5 V logic family requirements and through-hole packaging constraints. Compare performance metrics against modern HC or ALS alternatives if space or power efficiency are critical factors.

Counter Dividers Part Context

This part belongs to the SN54/74S series of synchronous 4-bit counters, which utilizes Schottky diodes to achieve faster switching speeds compared to standard TTL families. The N3 designation typically identifies the specific package style and manufacturing revision within the broader SN74S163 product line.

Counter Dividers Replacement Considerations

SN74S163N is the primary functional equivalent without the specific suffix. SN74LS163N offers lower power consumption but reduced speed. SN74HC163N provides CMOS compatibility with wider voltage ranges.
