MAX202CDR

Drivers, Receivers, Transceivers Overview

The MAX202CDR is a dual line driver and receiver integrated circuit manufactured by Texas Instruments, designed for RS-232 communication interfaces. It operates on a single 5 V power supply with a voltage range of 4.5 V to 5.5 V. The device features two drivers and two receivers, supporting full-duplex data transmission at rates up to 120 kb/s. It utilizes a charge pump architecture requiring only four external capacitors. The component is housed in a 16-pin SOIC package and supports surface mount installation. It functions within an industrial temperature range of -40°C to +85°C and includes ±15 kV ESD protection on all pins.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual drivers and receivers for full-duplex RS-232 signaling
• Operates from a single 5 V supply using internal charge pumps
• Provides robust ±15 kV electrostatic discharge protection across all interface pins

Drivers, Receivers, Transceivers Applications

• Connecting asynchronous communication controllers to serial port connectors
• Industrial equipment requiring reliable serial data exchange
• Embedded systems utilizing standard RS-232 protocols

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CDR' corresponds to the commercial temperature grade (-40°C to +85°C) and SOIC-16 tape-and-reel packaging configuration. Confirm RoHS compliance status and REACH registration details against the latest manufacturer documentation prior to integration. Ensure ordering specifications match the required operating environment constraints.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 transceiver is required for space-constrained surface-mount designs. It serves as a direct replacement for legacy through-hole variants like the MAX202CPE. Consider the 120 kb/s speed limit and 15 mA supply current when evaluating power budgets and baud rate requirements for the target application.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202 family of low-power RS-232 transceivers. It shares functional compatibility with other variants such as the MAX202IDR and MAX202CD, differing primarily in temperature ratings and packaging formats. The series is widely used in legacy serial communication interfaces where standard voltage levels must be converted for microcontroller connectivity.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX202IDR offers identical electrical performance but supports an extended industrial temperature range. The MAX202CD provides the same functionality in tube packaging rather than tape-and-reel format.
