SN74LS163ANSR

Counter Dividers Overview

The SN74LS163ANSR is a synchronous 4-bit binary counter from the Texas Instruments 74LS series. It features a positive-edge-triggered clock input and operates within a supply voltage range of 4.75 V to 5.25 V. The device provides parallel data inputs for synchronous preset capability and includes dedicated outputs for ripple carry and terminal count. Designed for surface-mount applications, it utilizes a 16-pin SOIC package and supports an operating temperature range from 0°C to +70°C.

Counter Dividers Feature Summary

• Synchronous four-bit binary counting with positive-edge triggering
• Parallel load functionality via synchronous preset inputs
• Dedicated ripple carry output for cascading multiple counters
• Terminal count output indicating completion of a full cycle

Counter Dividers Applications

• Digital timing sequences and event counters
• Frequency division circuits in digital systems
• Cascaded multi-stage counting applications
• Control logic for sequential state machines

Counter Dividers Procurement Notes

Verify the specific suffix 'ANSR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the supply voltage strictly adheres to the 4.75 V to 5.25 V limit to maintain signal integrity. Confirm that the operating environment remains within the specified commercial temperature range during deployment.

Counter Dividers Selection Notes

Select this component when a synchronous reset and parallel load are required for precise timing control. The LS series offers standard TTL compatibility suitable for legacy or mixed-logic designs. Consider alternative HC or HCT variants if lower power consumption or wider voltage ranges are necessary for the target application.

Counter Dividers Part Context

This part belongs to the widely used 74LS163 family of synchronous binary counters. It serves as a fundamental building block for digital electronics requiring reliable up-counting operations. The device distinguishes itself through synchronous control signals, preventing race conditions common in asynchronous designs.

Counter Dividers Replacement Considerations

The SN74LS163AD is a documented pin-compatible surface-mount alternative. Verify electrical characteristics and package dimensions before substitution.
