MAX202CPWR

Drivers, Receivers, Transceivers Overview

The MAX202CPWR is a dual RS-232 line driver and receiver manufactured by Texas Instruments, designed for single-supply operation. It integrates two charge pumps to generate the required ±10V levels from a single +5V supply, eliminating the need for external negative voltage sources. The device supports data rates up to 120 kbps and features ±15-kV electrostatic discharge (ESD) protection on all RS-232 lines. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum quiescent current of 15 mA. The component is housed in a TSSOP-16 surface-mount package and is rated for an industrial operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge pumps to convert a single +5V supply into the ±10V output levels required for RS-232 communication.
• Provides robust ±15-kV ESD protection on all RS-232 signal pins, including ground, ensuring reliability in harsh environments.
• Supports full-duplex asynchronous communication with data signaling rates reaching up to 120 kbps.
• Complies with TIA/EIA-232-F standards while requiring only four small external capacitors for operation.

Drivers, Receivers, Transceivers Applications

• Serial communication interfaces between microcontrollers and PC serial ports.
• Industrial control systems requiring reliable RS-232 connectivity.
• Embedded devices with limited power supply options needing single-supply RS-232 conversion.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CPWR' against the manufacturer's official datasheet to confirm the TSSOP-16 package and industrial temperature grade (-40°C to +85°C). Ensure that the ordering information matches the exact pinout and electrical specifications defined in the latest TI documentation before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 transceiver is needed for single-supply applications. It is suitable for designs requiring high ESD immunity and compact surface-mount packaging. Compare against similar models like the MAX202IDR or MAX202IPW based on specific package requirements and temperature ranges.

Drivers, Receivers, Transceivers Part Context

The MAX202 series is a legacy family of RS-232 transceivers widely used in serial communication applications. The MAX202CPWR variant specifically denotes the commercial/industrial temperature range and TSSOP-16 package. This part belongs to the broader class of low-power, single-supply RS-232 drivers developed by Texas Instruments and its predecessor Maxim Integrated.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements include the MAX202IDR and MAX202IPW. Verify that the substitute part number meets the same TSSOP-16 package and temperature range requirements as specified in the original design constraints.
