DS89C386TMEA

Overview

The DS89C386TMEA is an RS-422/RS-485 interface integrated circuit manufactured by Texas Instruments, formerly National Semiconductor. It features twelve drivers and zero receivers in a 48-pin SSOP package. The device operates at a supply voltage of 5 V with a maximum operating current of 1.5 mA. It supports data rates up to 25 Mbps and functions within a temperature range of -40°C to +85°C. The component is classified as obsolete and does not comply with RoHS standards.

Feature Summary

Provides twelve differential line drivers for high-speed serial communication
Supports both RS-422 and RS-485 bus protocols
Designed for surface-mount installation in compact electronic assemblies

Applications

Industrial control systems requiring multi-drop communication
Building automation networks utilizing RS-485 buses
Data acquisition modules interfacing with central controllers

Procurement Notes

Verify the obsolete status and RoHS non-compliance before procurement. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing 5V logic levels and thermal requirements for the target application environment.

Selection Notes

Select this component when a high-density driver solution is required for RS-422 or RS-485 networks. Consider the 48-SSOP package constraints and the specific need for twelve independent drivers. Evaluate alternative active components if RoHS compliance is mandatory for the final product.

Part Context

This part belongs to the DS89C387 family of interface ICs. It shares similar functional characteristics but differs in pinout or specific electrical parameters compared to its counterparts. The manufacturer transition from National Semiconductor to Texas Instruments affects documentation lineage.
