The device provides bidirectional drive capabilities for bus-oriented microprocessor systems, ensuring reliable data transfer across digital logic interfaces.

Feature Summary

• High-speed Schottky transistor-transistor logic construction
• TRI-STATE output capability for bus isolation
• Bidirectional data transmission support

Applications

• Bus-oriented microprocessor systems
• Digital logic interface circuits
• Data bus buffering applications

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor assets are now part of Texas Instruments. Confirm the specific package type matches your PCB footprint requirements. Ensure the datasheet version corresponds to the original National Semiconductor specifications rather than updated TI revisions if legacy compatibility is critical for your design integration.

Selection Notes

Select this component when an 8-bit wide bidirectional buffer with TRI-STATE control is required for TTL-compatible logic levels. Consider the Schottky speed characteristics for timing-sensitive bus applications. Verify that the power supply voltage and current drive capabilities align with the connected load requirements in the target system architecture.

Part Context

This device belongs to the broader family of 8-bit bus transceivers designed for digital signal routing. It serves as a standard interface solution between different logic domains or memory banks in embedded systems. The TRI-STATE feature allows multiple devices to share a common data bus without electrical contention during inactive periods.

Replacement Considerations

Check for direct pin-compatible equivalents such as the SN74LS245 or similar 8-bit transceivers. Verify logical equivalence regarding direction control and enable signals before substitution. Ensure the replacement maintains the same TRI-STATE behavior and voltage level compatibility.
