SN74LS163AD

Counter Dividers Overview

The SN74LS163AD 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 synchronous preset and synchronous reset capabilities, triggered on the positive edge of the clock signal. It is housed in a 16-SOIC surface-mount package with a narrow body width of 3.90 mm. The component functions as an up-counter and includes ripple carry outputs for cascading applications.

Counter Dividers Feature Summary

• Synchronous four-bit binary counting architecture with positive-edge clock triggering
• Integrated synchronous load and synchronous clear control inputs
• Ripple carry output functionality designed for multi-stage counter expansion

Counter Dividers Applications

• Digital timing sequence generation circuits
• Frequency division and pulse counting modules
• Cascaded digital system state tracking

Counter Dividers Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and temperature rating. Confirm RoHS compliance status through current datasheets, as legacy variants may differ. Ensure the procurement channel provides valid traceability for obsolete or end-of-life components. Cross-reference ordering part numbers with distributor databases to avoid substitution errors during acquisition.

Counter Dividers Selection Notes

Select this component when a low-speed synchronous binary counter is required for standard 5V logic systems. The LS series offers moderate speed suitable for general-purpose timing applications. Consider alternative packages if surface-mount constraints are not met. Evaluate power consumption requirements relative to other 74-series families before finalizing the design choice.

Counter Dividers Part Context

This device belongs to the Texas Instruments 74LS163A family of synchronous counters. It shares functional compatibility with other 74LS163 variants while differing in packaging and manufacturing revisions. The AD suffix specifically denotes the SOIC-16 surface-mount configuration. This part represents a standard solution for basic binary counting tasks in industrial and consumer electronics.
