SN74S163N

Counter Dividers Overview

The SN74S163N is a synchronous 4-bit binary counter from the Texas Instruments SN54/74S162 and SN54/74S163 series. It features positive-edge triggering, synchronous preset capability, and synchronous reset functionality. The device operates within a standard temperature range and utilizes Schottky TTL technology for high-speed performance.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with positive-edge clock triggering
• Synchronous parallel data loading via dedicated preset inputs
• Synchronous master reset that clears all outputs simultaneously

Counter Dividers Applications

• Digital frequency division circuits
• Event counting systems
• Timing sequence generation logic

Counter Dividers Procurement Notes

Verify the manufacturer source carefully as this component belongs to an older legacy logic family. Confirm the specific revision level and package integrity upon receipt. Ensure compatibility with existing system voltage levels before integration into new designs.

Counter Dividers Selection Notes

Select this part when high-speed Schottky TTL performance is required alongside synchronous control features. Compare against SN74LS163 variants if lower power consumption is prioritized over switching speed. Verify pinout compatibility with existing PCB layouts during the design phase.

Counter Dividers Part Context

This component is part of the broader SN54/74S16x family of synchronous counters. It shares functional similarities with other 4-bit binary counters but distinguishes itself through Schottky clamping diodes that enhance switching speed and reduce propagation delay compared to standard TTL counterparts.
