MAX202CDW

Drivers, Receivers, Transceivers Overview

The MAX202CDW is a dual RS-232 line driver and receiver manufactured by Texas Instruments, designed for asynchronous communication controllers. It operates on a single +5V power supply, utilizing internal charge pumps to generate the required ±10V output levels for RS-232 signaling. The device features two drivers and two receivers, supporting data rates up to 120 kbps with a maximum output slew rate of 30 V/µs. It is housed in a 16-pin SOIC package and complies with TIA/EIA-232-F standards.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge pump circuits to convert a single +5V supply into the ±10V voltage levels necessary for RS-232 communication without external high-voltage sources.
• Provides robust electrostatic discharge (ESD) protection rated at ±15 kV on all pins, including ground, ensuring signal integrity in high-noise environments.
• Includes built-in receiver input hysteresis to filter noise and ensure clean logic transitions during signal reception.

Drivers, Receivers, Transceivers Applications

• Connecting microcontrollers or DSPs to serial ports on PCs and peripherals.
• Industrial control systems requiring reliable serial communication interfaces.
• Data acquisition systems interfacing with modems or barcode scanners.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' indicates the wide-body SOIC-16 package variant. Confirm RoHS compliance status through official TI documentation, as manufacturing revisions may affect environmental certifications. Ensure the source provides valid datasheets matching the exact part number to avoid pinout mismatches.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single +5V supply is available and ±12V rails are absent. It is suitable for applications requiring moderate data rates up to 120 kbps. Consider alternative packages like ID or IP if narrower footprints or industrial temperature ranges (-40°C to +85°C) are required instead of the commercial range.

Drivers, Receivers, Transceivers Part Context

The MAX202 belongs to the Maxim Integrated MAX202 family of RS-232 transceivers. It serves as a foundational interface solution for legacy serial communications. The CDW suffix specifically denotes the commercial temperature grade and wide-body SOIC packaging, distinguishing it from industrial variants like the IDW or IPW.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX202IDR and MAX202IPW are direct functional substitutes within the same family. Verify that the replacement matches the required operating temperature range and physical package dimensions before integration.
