SN74LS163ADR

Counter Dividers Overview

The SN74LS163ADR is a synchronous 4-bit binary counter from the Texas Instruments 74LS series. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum counting rate of 25 MHz. The device features positive-edge triggering, synchronous preset, and synchronous reset capabilities. It is housed in a 16-SOIC surface-mount package and functions as an up-counter. The component is rated for operation between 0°C and +70°C.

Counter Dividers Feature Summary

• Synchronous four-bit binary counting with positive-edge clock triggering
• Independent synchronous preset and synchronous clear inputs for precise control
• Carry output provides ripple-free timing for cascading multiple counters

Counter Dividers Applications

• Digital frequency division circuits
• Timing and sequencing logic systems
• Cascaded multi-stage digital counters

Counter Dividers Procurement Notes

Verify the specific suffix 'ADR' against the manufacturer's official datasheet to confirm the SOIC-16 package and tape-and-reel orientation. Ensure the design environment strictly maintains the 4.75 V to 5.25 V power supply range. Confirm that the 0°C to +70°C operating temperature aligns with system requirements before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a standard TTL-compatible synchronous counter is required for low-cost applications. It serves as a direct replacement for legacy designs using the 74LS163 family. Consider alternative LV or HC series variants if lower power consumption or wider voltage tolerance is necessary for the target application.

Counter Dividers Part Context

This part belongs to the widely adopted 74LS (Low-power Schottky) logic family, known for balanced speed and power dissipation. The SN74LS163ADR variant specifically denotes the surface-mount SOIC packaging configuration. It represents a mature technology node suitable for established industrial and consumer electronics platforms requiring reliable binary counting.

Counter Dividers Replacement Considerations

The SN74LS163AD is a tube-packaged equivalent offering identical electrical performance. Verify pinout compatibility when transitioning between reel and tube formats.
