CD74ACT280M96

Overview

The CD74ACT280M96 is a single-circuit, 9-bit odd/even parity generator and checker from the Texas Instruments CD74ACT280 logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports standard operating voltages of 1.8 V, 2.5 V, 3.3 V, and 5 V. The device features buffered inputs and delivers high-level output currents of -24 mA and low-level output currents of 24 mA. Typical propagation delay is 10 ns at VCC = 5V, TA = 25°C, CL = 50pF. It exceeds 2kV ESD protection per MIL-STD-883, Method 3015. Power dissipation is 115 mW with maximum supply current of 8 uA. Operating temperature ranges from -55°C to +125°C.

Feature Summary

• Performs 9-bit odd or even parity generation and checking functions
• Features buffered inputs for signal integrity
• Provides high drive capability with ±24 mA output currents
• Exceeds 2kV ESD protection standards

Applications

• Data transmission systems requiring parity verification
• Memory modules for error detection
• Digital communication interfaces
• Microprocessor-based system data buses

Procurement Notes

Verify the specific suffix M96 indicates tape and reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the ACT logic family voltage requirements (4.5V–5.5V) match the target system design constraints before procurement.

Selection Notes

Select this component when 9-bit parity processing is required in high-speed digital applications. The ACT series offers faster performance than standard AC/HC families while maintaining CMOS power efficiency. Verify that the SOIC-14 package fits the PCB layout and that the 4.5V–5.5V supply range aligns with the system power rails.

Part Context

This part belongs to the Texas Instruments CD74ACT280 family of parity generators/checkers. It is designed for high-speed digital logic applications requiring reliable data integrity checks. The device integrates nine parity bits into a single IC, simplifying circuit design compared to discrete solutions.

Replacement Considerations

CD74AC280M96: Similar function but AC family has different speed and voltage characteristics. CD74ACT280M: Same logic family without reel packaging suffix; verify package compatibility.
