MAX3237EIDBR

Overview

The MAX3237EIDBR is a low-power RS-232 transceiver manufactured by Texas Instruments, designed for full-duplex communication. It integrates five drivers and three receivers within a single package, supporting data rates up to 1 Mb/s. The device operates from a single 3 V to 5.5 V supply and features a shutdown mode that reduces power consumption significantly. It includes ESD protection rated at 15 kV on all pins and utilizes small external capacitors. The component is housed in an SSOP-28 surface-mount package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates five independent line drivers and three line receivers for multi-channel serial communication
• Features 15 kV human-body model ESD protection on all RS-232 lines to enhance system reliability
• Includes a dedicated shutdown pin to minimize power consumption during idle periods
• Operates with small external charge-pump capacitors for efficient voltage generation

Applications

• Industrial control systems requiring robust serial communication interfaces
• Portable instrumentation and battery-powered devices utilizing low-power operation modes
• Data acquisition systems connecting multiple sensors via RS-232 protocols
• Embedded computing platforms needing high-density interface solutions

Procurement Notes

Verify the specific suffix IDBR indicates the reel packaging format when sourcing components. Confirm the manufacturer designation as Texas Instruments to distinguish from legacy Maxim Integrated versions. Ensure the order quantity aligns with standard reel sizes provided by authorized distributors. Check for RoHS compliance status relevant to current manufacturing batches.
