MAX202IDR

Drivers, Receivers, Transceivers Overview

The MAX202IDR is a dual RS-232 line driver and receiver manufactured by Texas Instruments, designed for asynchronous communication controllers. It operates from a single 5V supply using internal charge pumps and four external capacitors. The device provides full-duplex communication with two drivers and two receivers, supporting data rates up to 120 kb/s. It features ±15 kV ESD protection on all pins. Electrical specifications include a supply voltage range of 4.5 V to 5.5 V, a maximum operating current of 15 mA, and an operating temperature range of -40°C to +85°C. It is housed in a 16-SOIC surface-mount package.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual line drivers and receivers with internal charge pump circuitry for single-supply operation
• Provides ±15 kV electrostatic discharge (ESD) protection on all serial connector pins
• Supports full-duplex asynchronous data transmission at speeds up to 120 kb/s
• Complies with TIA/EIA-232-F interface standards

Drivers, Receivers, Transceivers Applications

• Connecting microcontrollers or DSPs to serial port connectors
• Interfacing asynchronous communication controllers with modems
• Point-to-point data communication links requiring ESD protection

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix ID against the manufacturer's datasheet to confirm the industrial temperature grade (-40°C to +85°C) and SOIC-16 package variant. Ensure that the required four external capacitors are included in the design, as they are mandatory for the internal charge pump operation. Confirm RoHS compliance status through official documentation before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 transceiver is needed with robust ESD protection for serial interfaces. It is suitable for applications requiring operation from a single 5V source without negative voltage generation. Consider the 120 kb/s speed limit and 16-pin footprint constraints during PCB layout planning.

Drivers, Receivers, Transceivers Part Context

The MAX202IDR belongs to the MAX202 family of RS-232 transceivers. This series is characterized by its ability to generate the necessary positive and negative voltages for RS-232 signaling directly from a single 5V supply. The 'I' designation indicates the industrial temperature range, while 'DR' specifies the tape-and-reel packaging format for automated assembly.
