CD74AC280M96

Overview

The CD74AC280M96 is a single 9-bit odd/even parity generator or checker from the Texas Instruments 74AC logic family. It operates within a supply voltage range of 1.5 V to 5.5 V, supporting standard voltages of 1.8 V, 2.5 V, 3.3 V, and 5 V. The device features a propagation delay of 263 ns and provides output drive currents of -24 mA for high levels and 24 mA for low levels. It is housed in an SOIC-14 surface-mount package and functions as a single circuit with nine bits. The component supports operation across a temperature range of -55 °C to +125 °C.

Feature Summary

• Performs 9-bit odd or even parity generation and checking functions
• Operates with balanced noise immunity at 30% of supply voltage
• Features anti-latch-up CMOS design with ESD protection exceeding 2 kV

Applications

• Data integrity verification in digital communication systems
• Parity error detection in memory subsystems
• High-speed data routing applications requiring parity checks

Procurement Notes

Verify the specific suffix M96 corresponds to the required tape and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOIC-14 footprint matches the target PCB layout constraints. Validate that the operating temperature range meets the environmental requirements of the final assembly.

Selection Notes

Select this component when a 9-bit parity function is required within the AC logic family specifications. Consider the 263 ns propagation delay for timing analysis in the target circuit. Evaluate the SOIC-14 package dimensions against available board space. Compare performance metrics against other parity generators if lower delay times are necessary for the application.

Part Context

This part belongs to the CD74AC280 series, which includes variants such as CD74AC280M and CD74AC280NSR. These devices share the same core parity functionality but differ in packaging options like SOIC, NS (SOIC), and PW (TSSOP). The M96 designation specifically identifies the surface-mount variant intended for automated assembly processes.

Replacement Considerations

Compatible substitutes include CD74AC280M and CD74AC280NSR. Verify pinout compatibility and electrical characteristics before substitution.
