SN74LVTH18502APM

Overview

The SN74LVTH18502APM is an 18-bit universal bus transceiver from the Texas Instruments SCOPE family, designed for 3.3-V ABT logic applications. It operates within a supply voltage range of 2.7 V to 3.6 V and supports an operating temperature range from -40°C to +85°C. The device is housed in a 64-LQFP package with surface-mount installation. It features high-speed data transfer capabilities suitable for memory and microcontroller-to-peripheral interfaces.

Feature Summary

• Provides 18-bit bidirectional data transmission between external buses and internal logic circuits
• Supports 3.3-V ABT technology for low power consumption and high noise immunity
• Includes configurable direction control to manage data flow direction dynamically

Applications

• Memory interface connections in embedded systems
• Microcontroller-to-peripheral communication links
• High-density data routing on system boards

Procurement Notes

Verify the specific suffix 'APM' corresponds to the LQFP-64 tray packaging configuration. Confirm moisture sensitivity level requirements align with your assembly line reflow profiles. Ensure the 3.3-V supply rail matches the component's rated maximum voltage specifications before integration.

Selection Notes

Select this component when an 18-bit wide data path is required at 3.3-V logic levels. Compare against the SN74ABTH18502APM if 5-V operation is necessary instead of 3.3-V. Consider the SN74LVTH18646A if integrated register storage functionality is needed alongside the bus transceiver features.

Part Context

This part belongs to the SN74LVTH18502A series, which utilizes ABT (Advanced BiCMOS Technology) to achieve high speed with low power dissipation. The SCOPE branding indicates its suitability for complex system-on-package or system-in-package designs requiring dense interconnectivity.

Replacement Considerations

The SN74ABTH18502APM serves as a compatible alternative for 5-V applications using the same pinout and package.
