SN74ABTH18502APMR

Universal Bus Functions Overview

The SN74ABTH18502APMR is an 18-bit universal bus transceiver from the Texas Instruments SCOPE family, designed for high-speed asynchronous communication. It operates within a supply voltage range of 2.7V to 3.6V and supports TTL input levels. The device features three-state outputs and is housed in a 64-pin LQFP package with dimensions of 10x10 mm. It is rated for operation between -40°C and +85°C and carries Moisture Sensitivity Level 3 certification.

Universal Bus Functions Feature Summary

• Provides 18-bit data transfer capability via a universal bus architecture
• Supports scan test equipment applications through integrated test functionality
• Features three-state outputs to facilitate bus line driving

Universal Bus Functions Applications

• Scan test equipment systems
• High-speed asynchronous communication interfaces
• Universal bus data transfer architectures

Universal Bus Functions Procurement Notes

Verify the specific suffix 'PMR' indicates tape-and-reel packaging distinct from tray variants. Confirm moisture sensitivity level 3 requirements during storage and handling. Ensure the 2.7V to 3.6V operating range aligns with target system power rails before finalizing procurement orders.

Universal Bus Functions Selection Notes

Select this component when 18-bit parallel data transfer is required in space-constrained designs utilizing the 64-LQFP footprint. It serves as a suitable alternative to standard bus transceivers where scan test capabilities are necessary. Verify that the 3.6V maximum supply voltage meets the logic interface requirements of the connected system components.

Universal Bus Functions Part Context

This part belongs to the SN74LVTH18(2)502A series, which integrates ABT technology with universal bus transceiver functions. The SCOPE branding denotes its specialization for scan test environments. It shares architectural similarities with other 18-bit devices in the Texas Instruments logic portfolio but offers specific voltage and pinout configurations.

Universal Bus Functions Replacement Considerations

The SN74ABTH18502APM is a compatible tray-packaged variant within the same functional family. Cross-reference datasheets to confirm identical electrical characteristics and pin assignments before substituting packaging types.
