CD74HC280MT

Overview

The CD74HC280MT is a high-speed CMOS logic device manufactured by Texas Instruments, functioning as a 9-bit odd/even parity generator and checker. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -55°C to 125°C. The component is housed in a 16-SOIC surface-mount package with 16 pins. It features a propagation delay of 26 ns at 6 V and maximum output currents of 5.2 mA for low-level and 4 mA for high-level states.

Feature Summary

• Performs simultaneous generation and checking of odd or even parity across nine data bits
• Provides dedicated outputs for both odd and even parity conditions
• Supports operation over an extended industrial temperature range

Applications

• Digital communication systems requiring error detection
• Data transmission interfaces utilizing parity verification
• Computer memory systems implementing error checking protocols

Procurement Notes

Verify the specific suffix 'MT' against the official Texas Instruments datasheet to confirm the tape-and-reel packaging configuration and ensure it matches the required manufacturing assembly process. Confirm RoHS compliance status and check for any recent product change notices that may affect pinout or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a single integrated circuit is needed to handle both parity generation and checking functions for nine-bit data streams. Ensure the system design accommodates the specified 2 V to 6 V supply voltage range and requires the extended temperature capability provided by the HC series logic family.

Part Context

This part belongs to the Texas Instruments CD74HC series of high-speed CMOS logic devices. The series is characterized by fast switching speeds and low power consumption, making it suitable for general-purpose digital logic applications where reliability and performance are critical requirements.

Replacement Considerations

Compatible alternatives include the SN74HC280 and SN74HCT280 from Texas Instruments, or the 74HC280 from Nexperia. Verify pin compatibility and electrical specifications before substitution.
