SN74ABT18502PM

Universal Bus Functions Overview

The SN74ABT18502PM is an 18-bit universal bus transceiver from the Texas Instruments SCOPE family, housed in a 64-pin LQFP package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended industrial temperature range from -40°C to +85°C. Designed for high-speed data transfer, this device features three-state outputs and is moisture sensitive, requiring appropriate handling during surface-mount assembly processes.

Universal Bus Functions Feature Summary

• Provides 18-bit bidirectional data transmission capability via universal bus architecture
• Integrates three-state outputs to facilitate direct connection to system buses
• Supports operation across the full industrial temperature range for reliable performance

Universal Bus Functions Applications

• High-density memory interface circuits
• Data acquisition systems requiring wide bus width
• Industrial control network nodes

Universal Bus Functions Procurement Notes

Verify the specific suffix 'PM' corresponds to the LQFP-64 tray packaging configuration. Confirm RoHS compliance status through official documentation. Ensure ESD protection measures are implemented due to moisture sensitivity classification. Validate that the 4.5V to 5.5V supply requirement matches the target system design constraints before procurement.

Universal Bus Functions Selection Notes

Select this component when an 18-bit wide bus interface is required within standard 5V logic families. The LQFP-64 package offers a compact footprint suitable for dense PCB layouts. Consider the extended temperature range if the application environment exceeds commercial limits. Verify pin compatibility with existing board designs utilizing the SCOPE series architecture.

Universal Bus Functions Part Context

This part belongs to the SN74ABTH18502A series, representing a specialized function logic category distinct from standard buffers or flip-flops. It shares architectural similarities with other SCOPE devices but provides a fixed 18-bit width optimized for parallel data paths rather than serial conversion or simple buffering tasks.

Universal Bus Functions Replacement Considerations

The SN74ABTH18502APM is a verified equivalent variant within the same product line. Both parts share identical functional specifications and electrical characteristics. Ensure the replacement maintains the same LQFP-64 package outline for mechanical compatibility.
