SN74ABTH182504APM

Universal Bus Functions Overview

The SN74ABTH182504APM is an 18-bit universal bus transceiver from the Texas Instruments SCOPE family, designed for high-speed data transfer in scan test equipment. It operates within a supply voltage range of 2.7V to 3.6V and supports an operating temperature range from -40°C to +85°C. The device utilizes a 64-pin LQFP package with surface-mount installation. It features Schmitt trigger inputs on port A to accept slow or noisy signals, while port B provides standard CMOS outputs. The component is rated as catalog quality and is humidity sensitive.

Universal Bus Functions Feature Summary

• Provides 18-bit bidirectional data transmission capability between two ports
• Incorporates Schmitt trigger inputs on Port A to filter noisy signal transitions
• Designed specifically for integration into automated scan test equipment architectures

Universal Bus Functions Applications

• Automated Test Equipment (ATE) scan chains
• High-speed board-to-board data interconnects
• Bus-oriented memory and I/O expansions

Universal Bus Functions Procurement Notes

Verify the specific suffix 'APM' corresponds to the 64-LQFP tray packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure the design accommodates the specified 2.7V to 3.6V supply voltage constraints. Check for any lead-free manufacturing specifications required by the target application environment.

Universal Bus Functions Selection Notes

Select this component when an 18-bit wide bus interface with noise-immune input characteristics is required. The inclusion of Schmitt triggers on one port makes it suitable for environments with signal integrity challenges. Compare against similar SCOPE devices if different pin counts or voltage ranges are needed. Ensure the LQFP-64 footprint matches the PCB layout constraints.
