74F163APC

Overview

The Fairchild Semiconductor 74F163APC is a high-speed synchronous modulo-16 binary counter belonging to the F/FAST series. It features a 4-bit architecture with positive edge triggering and operates within a TTL logic family. The device utilizes a 16-pin Plastic Dual-In-Line (PDIP) package. Key functional attributes include synchronous presettable loading, two count enable inputs, and a terminal count output for multi-stage expansion. It incorporates a synchronous reset input that overrides counting and parallel loading, allowing simultaneous output reset on the clock rising edge.

Feature Summary

• Synchronous counting and loading mechanism
• High-speed synchronous expansion capability
• Synchronous reset input functionality

Applications

• Programmable frequency dividers
• Synchronous multi-stage counter formation
• Digital timing control circuits

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status as historical data indicates potential non-compliance for specific variants. Ensure the DIP-16 package matches design requirements. Cross-reference ordering suffixes with current ON Semiconductor nomenclature due to Fairchild integration changes.

Selection Notes

Select this component for applications requiring high-speed synchronous binary counting with precise reset control. The synchronous reset feature distinguishes it from asynchronous counterparts like the 74F161A. Consider the F/FAST series speed characteristics against power consumption constraints. Verify voltage supply compatibility with standard TTL levels.

Part Context

This part belongs to the 74F163A family of synchronous presettable binary counters. It serves as a high-speed version of the standard 74F163. The 'PC' suffix denotes the PDIP-16 plastic dual-in-line package. Fairchild Semiconductor manufactured this component before its acquisition by ON Semiconductor.

Replacement Considerations

The 74F161A is a related variant but features asynchronous reset instead of synchronous reset. Direct pin-compatible substitutes may include other 74F163 equivalents from different manufacturers, provided they meet the same F/FAST speed and TTL interface specifications.
