MAX3237ECDB

Overview

The MAX3237ECDB is a true RS-232 transceiver manufactured by Texas Instruments, designed for operation with supply voltages ranging from 3 V to 5.5 V. It integrates five drivers and three receivers in a single package, supporting full-duplex communication at data rates up to 1 Mb/s. The device operates within an industrial temperature range of 0°C to +70°C and features low power consumption with a typical operating supply current of 2 mA. It includes a shutdown mode to minimize power usage during idle periods. The component provides robust protection against electrostatic discharge (ESD) with ratings up to 15 kV, ensuring reliable performance in demanding environments.

Feature Summary

• Integrates five independent line drivers and three line receivers for multi-channel serial communication
• Supports full-duplex data transmission at speeds up to 1 Megabit per second
• Features low-power shutdown mode to reduce energy consumption when not in use
• Provides high-level electrostatic discharge protection rated at 15 kilovolts

Applications

• Industrial control systems requiring multiple RS-232 connections
• Portable instrumentation and battery-powered devices
• Communication modules in embedded systems
• Data acquisition equipment with serial interface requirements

Procurement Notes

Verify the exact suffix 'DB' corresponds to the TSSOP-28 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering part number matches the specific temperature grade and packaging format required for your assembly process. Cross-reference with Texas Instruments datasheets to validate pinout compatibility.

Selection Notes

Select this component when designing circuits that require five transmit channels and three receive channels on a single IC. It is suitable for applications needing 3V to 5.5V operation without external charge pumps. Consider the TSSOP-28 package constraints for PCB layout. Compare against similar MAX3237 variants if different package types or extended temperature ranges are needed.

Part Context

This device belongs to the MAX3237E family of true RS-232 transceivers from Texas Instruments. The family shares core electrical characteristics but differs in packaging options such as SOIC, SSOP, and TSSOP. The ECDB designation specifically identifies the commercial temperature grade and surface-mount TSSOP-28 form factor within this product line.

Replacement Considerations

Direct substitutes include other MAX3237E variants with different packages like MAX3237ECDW or MAX3237ECPWR. Verify pin-to-pin compatibility before replacement. Alternative interfaces may require checking driver/receiver counts and voltage levels.
