It operates within a supply voltage range of 2.5 V to 3.3 V and utilizes BiCMOS technology for high-speed performance. The device features 3-state outputs and is housed in a 56-pin SSOP package. It supports industrial operating temperatures from -40°C to +85°C. This component integrates multiple logic functions into a single chip, facilitating efficient data transfer in low-voltage systems.

Feature Summary

• Supports 2.5-V and 3.3-V power supplies for low-voltage system integration
• Provides 18-bit bidirectional data transmission capability
• Features 3-state outputs to prevent bus contention
• Utilizes BiCMOS technology for enhanced switching speed

Applications

• High-performance memory mapping applications
• Clock drivers and buffering circuits
• Bus-oriented architectures requiring 18-bit width
• Low-voltage embedded control systems

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status when ordering. Confirm the package type matches the required PCB footprint, as variations exist between SSOP and TSSOP formats. Ensure the voltage domain aligns with the 2.5 V or 3.3 V operational requirements specified in the datasheet. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component for designs requiring wide bus widths in low-voltage environments. Compare propagation delay specifications against system timing constraints. Evaluate the pin count and package dimensions against available board space. Consider the industrial temperature range if the application operates in harsh conditions. Verify compatibility with existing logic families regarding input/output voltage levels.

Part Context

This device belongs to the ALVTH series of universal bus transceivers. It serves as a bridge between different logic domains in complex digital systems. The 18-bit configuration reduces component count compared to using multiple 8-bit or 9-bit transceivers. It is designed for applications demanding high throughput and reliable data integrity in compact form factors.

Replacement Considerations

Check for direct substitutes such as the SN74ABT16601 series for higher voltage operation. Verify pin-to-pin compatibility before replacing with other 18-bit transceivers. Ensure electrical characteristics like drive strength and delay times meet original design specifications.
