74HC280FPEL-E

Overview

The 74HC280FPEL-E is a high-speed silicon-gate CMOS logic device belonging to the HC/UH series, manufactured by Renesas Electronics Corporation. It functions as a 9-bit odd/even parity generator and checker with complementary outputs. The component is housed in a 14-pin plastic dual in-line package (PDIP-14). It operates within a temperature range of -55 °C to +125 °C and features a propagation delay of 300 ns.

Feature Summary

• Generates or checks odd and even parity for nine data bits
• Provides complementary output signals
• Word length can be easily expanded through cascading

Applications

• Parity generation and checking in digital communication systems
• Data integrity verification in memory interfaces
• Error detection circuits in microprocessor-based systems

Procurement Notes

Verify the specific suffix 'E' against the manufacturer's official documentation to confirm environmental compliance status and exact pinout compatibility. Ensure the PDIP-14 package dimensions match the target PCB footprint requirements. Confirm that the operating temperature range meets the system's thermal specifications before finalizing procurement.

Selection Notes

Select this component when a 9-bit parity solution with complementary outputs is required. The HC series offers high-speed performance suitable for general-purpose logic applications. Consider the wide operating temperature range if the environment exceeds standard commercial limits. Verify voltage compatibility with the host system logic levels.

Part Context

This part belongs to the Renesas 74HC/UH series of high-speed CMOS logic devices. These components are designed to be pin-compatible with low-power Schottky TTL standards, facilitating upgrades in existing designs. The 74HC280 specifically addresses parity generation needs within this family, offering a standardized solution for data validation tasks.

Replacement Considerations

Compatible equivalents include the NXP 74HC280 and Texas Instruments CD74HC280. Verify pin compatibility and electrical characteristics before substitution.
