N74F280BD,623

Overview

The N74F280BD,623 is a 9-bit odd/even parity generator and checker manufactured by NXP USA Inc. It operates within a supply voltage range of 4.5V to 5.5V and features high-impedance NPN base inputs with a typical propagation delay of 5.5ns. The device provides separate Even (∑E) and Odd (∑O) outputs for error detection in data transmission systems. It is housed in a 14-pin plastic small outline package (SO) and supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides simultaneous even and odd parity generation or checking for up to nine data bits
• Features buffered inputs that present only one normalized load to the driving circuit
• Supports cascading multiple devices to expand word length capabilities for larger data words

Applications

• Error detection in high-speed data transmission systems
• Data retrieval system integrity verification
• Cascaded parity checking for extended word sizes

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm the specific suffix matches the required commercial or industrial temperature rating. Ensure the 14-pin SO package dimensions align with the target PCB footprint. Check for RoHS compliance status relative to current environmental regulations.

Selection Notes

Select this component when 9-bit parity processing is required within the 74F logic family. Consider the 5.5ns typical propagation delay for timing constraints. Evaluate the need for industrial temperature ratings (-40°C to +85°C) versus standard commercial ranges. Assess input loading requirements against the driving source capabilities.

Part Context

This part belongs to the 74F series of high-speed TTL-compatible logic ICs originally developed by Philips Semiconductors. The N74F280B variant specifically addresses parity generation needs. The 'D' suffix indicates the 14-pin plastic small outline package configuration used for surface-mount applications.
