74AC280SC

Overview

The Fairchild Semiconductor 74AC280SC is a high-speed CMOS logic device functioning as a 9-bit parity generator and checker. It operates within a supply voltage range of 2V to 6V, ensuring compatibility with standard AC logic families. The component utilizes a 14-pin Small Outline Integrated Circuit (SOIC) package, providing a compact footprint for surface-mount applications. Designed for robust performance, it supports data rates suitable for various digital communication protocols requiring error detection capabilities.

Feature Summary

• Performs simultaneous generation and checking of parity bits for 9-bit data words
• Utilizes high-speed CMOS technology for low power consumption and fast switching
• Features a single output pin indicating the parity status of the input data

Applications

• Digital communication systems requiring error detection
• Data bus monitoring circuits
• Microprocessor interface designs

Procurement Notes

Verify the manufacturer datasheet to confirm the specific electrical characteristics and thermal limits for the 74AC280SC. Ensure the SOIC-14 package dimensions match your PCB layout requirements. Cross-reference the part number with official distributor catalogs to validate authenticity and current production status before procurement.

Selection Notes

Select the 74AC280SC when a dedicated 9-bit parity solution is required in a compact surface-mount form factor. Consider its operating voltage range and speed specifications relative to other system components. Verify that the logic family compatibility aligns with existing circuit design constraints.

Part Context

This component belongs to the 74AC series of high-speed CMOS logic devices manufactured by Fairchild Semiconductor. The series is characterized by operation speeds comparable to LS TTL but with lower power consumption. The 74AC280SC specifically addresses parity functions within this logical family.

Replacement Considerations

The 74AC280SCX is an alternative ordering option from the same manufacturer, typically differing only in packaging format such as tape and reel configuration rather than functional parameters.
