SN74ABTH18504APM

Overview

The SN74ABTH18504APM 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 2.7 V to 3.6 V and supports an extended industrial temperature range from -40°C to +85°C. The device features three-state outputs and is designed for high-speed data transfer applications requiring low power consumption and robust performance in complex digital systems.

Feature Summary

• Provides 18-bit bidirectional data transmission capability for system interconnects
• Incorporates three-state outputs to facilitate direct connection to system buses
• Designed with low power consumption characteristics suitable for portable applications

Applications

• High-speed data acquisition systems
• Memory mapping architectures
• Complex digital signal processing interfaces

Procurement Notes

Verify the specific suffix 'APM' corresponds to the LQFP-64 tray packaging configuration. Confirm moisture sensitivity levels and reflow soldering profiles align with your assembly process requirements. Ensure the operating voltage range matches your system's power rails before integration.

Selection Notes

Select this component when an 18-bit wide data path is required between logic devices. Compare against similar SCOPE family members like the SN74ABTH18502A for pin compatibility or channel count differences. Consider the LQFP-64 footprint constraints during PCB layout design to ensure adequate thermal dissipation and signal integrity.

Part Context

This part belongs to the SN74ABTH1850xA series of universal bus transceivers. It shares functional similarities with other 18-bit transceivers but offers specific electrical characteristics tailored for ABT technology. The device complements Texas Instruments' broader portfolio of specialty function logic ICs designed for high-performance computing and communication equipment.

Replacement Considerations

Check for direct cross-references within the SN74ABTH1850xA series. Verify pin-to-pin compatibility with legacy 18-bit transceivers if upgrading existing designs. Consult official substitution guides for any minor parameter variations that might affect system timing.
