74LVTH18502APMRG4

Universal Bus Functions Overview

The SN74LVTH18502APMRG4 is an 18-bit universal bus transceiver from the Texas Instruments SCOPE family, designed for low-voltage ABT logic applications. It operates within a supply voltage range of 2.7 V to 3.6 V and supports surface-mount installation in a 64-LQFP package measuring 10x10 mm. The device functions as a scan test equipment component with universal bus transceiver capabilities. It is rated for an extended operating temperature range from -40°C to +85°C and complies with RoHS3 standards. The component features three-state outputs and is moisture sensitive with an MSL rating of 3.

Universal Bus Functions Feature Summary

• Provides 18-bit bidirectional data transfer capability between external buses and internal logic circuits.
• Supports high-speed scanning test equipment architectures through integrated universal bus transceiver functionality.
• Features three-state outputs to facilitate direct connection to system data lines without additional buffering.

Universal Bus Functions Applications

• Scan test equipment interfaces
• High-density data bus systems
• Universal bus transceiver implementations

Universal Bus Functions Procurement Notes

Verify the specific ordering suffix 'G4' confirms RoHS3 compliance and lead-free status during procurement. Confirm the package variant matches the 64-LQFP (10x10) footprint requirements for your PCB layout. Ensure moisture sensitivity level 3 handling protocols are followed if the component has exceeded shelf life limits prior to soldering.

Universal Bus Functions Selection Notes

Select this component when designing systems requiring 18-bit wide data paths at low voltages. It is suitable for applications needing ABT performance characteristics within the 2.7 V to 3.6 V supply range. Consider the LQFP-64 package constraints regarding board space and thermal dissipation compared to smaller logic families.

Universal Bus Functions Part Context

This part belongs to the SN74LVTH18(2)502A series, which includes variants like the SN74LVTH18502APM and SN74LVTH182502APMR. The 'G4' suffix typically denotes environmental enhancements such as lead-free packaging and specific manufacturing lot traceability within the Texas Instruments product line.

Universal Bus Functions Replacement Considerations

Direct replacements include the SN74LVTH18502APM or SN74LVTH182502APMR, provided the package type and pinout compatibility are verified. Ensure any substitute maintains the same 2.7 V to 3.6 V operating voltage range and 18-bit width specification.
