N74F280BN,602

Overview

The N74F280BN,602 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 loading of 20μA in both Low and High states. The device provides Even (∑E) and Odd (∑O) outputs for data integrity verification. Typical propagation delay from data inputs to outputs is 5.5ns, with a typical total supply current of 26mA. It is housed in a 14-pin plastic dual in-line package (DIP).

Feature Summary

• Generates or checks even and odd parity on up to 9 bits of data.
• Features buffered inputs providing one normalized load per pin.
• Allows word length expansion by cascading multiple devices.

Applications

• Error detection in high-speed data transmission systems.
• Data retrieval system error checking.
• Parity generation for digital logic circuits.

Procurement Notes

Verify the specific suffix '602' against official manufacturer documentation to confirm commercial temperature range availability and exact packaging specifications. Ensure compatibility with existing 74F series logic levels and power supply constraints before integration into designs requiring industrial temperature ranges.

Selection Notes

Select this component when 9-bit parity checking is required within standard 74F logic families. Consider cascading capabilities for larger word sizes. Verify that the commercial temperature range meets application requirements, as industrial variants may require different ordering codes.

Part Context

This part belongs to the 74F series of high-speed TTL-compatible logic ICs. It serves as a specialized functional block for data integrity monitoring within broader digital processing architectures, distinct from general-purpose gates or memory components.
