MAX202CD

Drivers, Receivers, Transceivers Overview

The MAX202CD is a dual RS-232 transceiver manufactured by Texas Instruments, designed for single-supply operation. It integrates two line drivers and two line receivers with an internal charge pump circuit that converts a +5V supply to the required ±10V levels, eliminating the need for external negative voltage sources. The device supports data rates up to 120 kbps and complies with EIA/TIA-232-F standards. It features ±15-kV electrostatic discharge (ESD) protection on all pins. The component operates within a supply voltage range of 4.5V to 5.5V and draws a typical supply current of 15 mA. It is housed in a 16-pin SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual line drivers and dual line receivers with an internal charge pump for single-supply operation
• Provides ±15-kV ESD protection on all serial port connection pins including ground
• Supports asynchronous communication controller interfacing via standard serial connectors

Drivers, Receivers, Transceivers Applications

• Interfacing asynchronous communication controllers with serial port connectors
• Battery-powered systems requiring RS-232 communication without negative voltage supplies
• Industrial control systems utilizing EIA/TIA-232-F compliant interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CD' indicates the commercial temperature range and SOIC-16 package configuration. Confirm RoHS compliance status as manufacturing revisions may alter environmental declarations. Ensure the source document explicitly lists the part number as active or obsolete to determine long-term availability viability.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 interface is required from a single 5V supply. It is suitable for applications needing moderate data rates up to 120 kbps. Consider alternative models if higher speed, lower power consumption, or extended industrial temperature ranges are necessary for the specific design constraints.

Drivers, Receivers, Transceivers Part Context

The MAX202 belongs to the Maxim Integrated RS-232 transceiver family, now under Texas Instruments. It serves as a foundational component for legacy serial communication interfaces. The device simplifies board design by integrating the charge pump, reducing the external capacitor count compared to earlier generations like the MAX201.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX202IDR is a pin-compatible alternative available in tape-and-reel packaging. Other variants such as the MAX202CPE offer different package options. Verify electrical specifications and temperature ranges match before substitution.
