SN74LS163AN

Counter Dividers Overview

The SN74LS163AN is a synchronous 4-bit binary counter from the Texas Instruments SN74LS163A series. It operates within a supply voltage range of 4.5 V to 5.25 V and supports an operating temperature range of 0°C to +70°C. The device utilizes a 16-pin DIP package for through-hole mounting. It features synchronous preset capability, allowing data loading on the clock edge, and includes synchronous reset functionality. The logic family is LS TTL, designed for standard digital counting applications requiring reliable performance.

Counter Dividers Feature Summary

• Synchronous four-bit binary up-counter architecture
• Synchronous parallel data preset capability
• Synchronous clear/reset function

Counter Dividers Applications

• Digital timing sequences
• Frequency division circuits
• Event counting systems

Counter Dividers Procurement Notes

Verify the specific suffix 'AN' corresponds to the PDIP-16 through-hole package variant. Confirm RoHS compliance status as documentation may vary by production batch. Ensure the design accommodates the specified 4.5 V to 5.25 V supply voltage range and industrial temperature limits. Cross-reference with official Texas Instruments datasheets for pinout accuracy before finalizing procurement specifications.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter with parallel load and synchronous clear is required in a through-hole configuration. The LS logic family offers moderate speed suitable for general-purpose digital designs. Consider alternative packages like SOIC if surface mount technology is preferred, or verify compatibility with existing board layouts requiring 16-pin DIP footprints.

Counter Dividers Part Context

This part belongs to the SN74LS163A family of synchronous 4-bit binary counters. It shares functional similarities with other members of the 74LS163 series but differs in packaging and specific manufacturing revisions. The SN74LS163AN specifically denotes the through-hole DIP variant, distinguishing it from surface-mount equivalents like the SN74LS163AD.

Counter Dividers Replacement Considerations

SN74LS163AD is a surface-mount equivalent. SN74ALS163BN offers faster switching speeds in a similar form factor.
