CD74AC280M96G4

Overview

The CD74AC280M96G4 is a parity generator and checker manufactured by Texas Instruments, belonging to the 74AC logic family. It features nine data inputs and provides both even and odd parity outputs. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports a high-level output current of -24 mA and a low-level output current of 24 mA. Propagation delay is specified at 263 ns. It is housed in a 14-pin SOIC package and functions across an operating temperature range of -55°C to +125°C.

Feature Summary

• Generates and checks parity for nine-bit data streams
• Provides simultaneous even and odd parity outputs
• Features balanced propagation delays for system timing consistency

Applications

• Data integrity verification in digital communication systems
• Memory error detection circuits
• High-speed data routing applications

Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS status against the manufacturer's official documentation. Confirm the M96 suffix corresponds to the tape and reel packaging format rather than tube packaging. Ensure the component meets the required environmental specifications for the intended application environment before procurement.

Selection Notes

Select this component when nine-bit parity checking or generation is required within the AC logic family constraints. Consider the 1.5 V to 5.5 V operating range for compatibility with various power supplies. Evaluate the 263 ns propagation delay against system clock speeds to ensure timing requirements are met without signal integrity issues.

Part Context

This part belongs to the Texas Instruments 74AC series of high-speed CMOS logic devices. The AC series offers performance improvements over earlier HC families while maintaining similar pinouts. The CD74AC280 specifically addresses parity functions, distinguishing it from standard logic gates or flip-flops within the same broader product category.

Replacement Considerations

Check for CD74AC280 variants with different suffixes that may offer alternative packaging options such as tubes instead of reels. Verify cross-compatibility with other manufacturers' 74AC280 equivalents if supply chain diversification is necessary.
