74HC280FP-E

Overview

The CD74HC280FP-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 nine-bit odd/even parity generator and checker with complementary outputs. The component is housed in a 14-lead plastic dual in-line package (PDIP). 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 expansion capability through cascading

Applications

• Parity generation and checking for 25-line systems
• Parity generation and checking for 81-line systems

Procurement Notes

Verify the specific suffix 'FP-E' against official Renesas documentation to confirm package type and material specifications. Ensure compatibility with existing system voltage levels and operating temperature ranges before procurement. Confirm RoHS compliance status if required by project standards.

Selection Notes

Select this component when a nine-bit parity solution is required with complementary outputs. Consider the HC/UH series characteristics for high-speed operation. Verify that the PDIP-14 package fits the available board space and manufacturing constraints.

Part Context

This part belongs to the widely used 74HC280 family of parity generators. It serves as a standard logic component for error detection in digital communication and data processing systems. The Renesas variant maintains pin compatibility with industry-standard equivalents.

Replacement Considerations

Compatible substitutes include the NXP 74HC280 and Texas Instruments CD74HC280. Verify pinout and electrical specifications match before substitution.
