74ACT11286D

Overview

The SN74ACT11286D is a 9-bit parity generator and checker featuring a bus driver parity I/O port. It operates within a supply voltage range of 4.5 V to 5.5 V. The device provides local output for parity checking and supports high-drive current capabilities with low-level output current of 24 mA and high-level output current of -24 mA. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Universal 9-bit parity generation and checking functionality
• Integrated bus-driving parity I/O port for external communication
• Local output capability dedicated to internal parity verification

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature grade. Confirm that the component matches the required logic family specifications for your design. Cross-reference the part number with the latest datasheet revision to avoid discrepancies in pinout or electrical characteristics during procurement.

Selection Notes

Select this component when 9-bit parity handling is required alongside bus driving capabilities. Ensure the system voltage aligns with the 4.5 V to 5.5 V operating range. Consider the SOIC-14 package constraints for PCB layout. Verify that the propagation delay and drive strength meet the timing requirements of the target application interface.

Part Context

This device belongs to the Texas Instruments 74ACT logic family, designed for high-speed CMOS applications. It integrates parity functions with bus drivers, distinguishing it from standard logic gates. The 74ACT series offers performance comparable to LS-TTL but with lower power consumption and wider voltage tolerance suitable for modern digital systems.

Replacement Considerations

Check for direct equivalents within the same 74ACT family. Verify pin compatibility and logical function equivalence before substitution. Consult the manufacturer's cross-reference guide for validated alternative part numbers.
