74HC280P-E

Overview

The CD74HC280E96 is a 9-bit parity generator/checker from the HC/UH series, featuring complementary outputs and housed in a PDIP-14 package. It operates within a temperature range of -55 °C to +125 °C and exhibits a propagation delay of 300 ns.

Feature Summary

• Generates odd or even parity for nine data bits
• Word-length easily expanded by cascading
• Similar pin configuration to the “180” for easy system up-grading

Applications

• 25-line parity generator/checker
• 81-line parity generator/checker

Procurement Notes

Verify the exact manufacturer designation, as the model number corresponds to NXP Semiconductors while the prompt specifies Renesas Electronics Corporation. Confirm if the intended component is the Hitachi-derived HD74HC280P-E or the Texas Instruments CD74HC280E96. Ensure the package type and electrical specifications match the specific project requirements before procurement.

Selection Notes

Select this component for applications requiring high-speed CMOS logic with LSTTL compatibility. The device supports standard output capabilities and MSI integration levels. Consider the wide operating voltage and temperature ranges when designing for industrial or commercial environments requiring robust parity checking functions.

Part Context

This component belongs to the 74HC280 family of logic integrated circuits. These devices are designed for high-speed operation and are pin-compatible with low power Schottky TTL standards. They are specified in compliance with JEDEC standard no. 7A, ensuring interoperability within broader digital logic systems.

Replacement Considerations

Compatible substitutes include the 74AC280, 74ACT280, and MM74HC280. Verify pinout compatibility and electrical characteristics against the original design specifications to ensure seamless integration without circuit modification.
