MAX202CPW

Drivers, Receivers, Transceivers Overview

The MAX202CPW 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 source, eliminating the need for external negative voltage supplies. The device features two drivers and two receivers, supporting data rates up to 120 kbps. It includes ±15-kV electrostatic discharge (ESD) protection on all pins. Packaged in a 16-pin TSSOP, it operates within a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Single-supply operation enabled by internal charge pump circuitry
• Integrated ±15-kV ESD protection on all serial port pins
• Compliance with TIA/EIA-232-F interface standards

Drivers, Receivers, Transceivers Applications

• Serial communication interfaces between microcontrollers and DB9 connectors
• Industrial control systems requiring robust ESD protection
• Battery-powered devices utilizing single 5V logic supplies

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CPW indicates the commercial temperature grade and TSSOP-16 package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering quantities align with tube packaging specifications provided by authorized distributors.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 transceiver is required with integrated ESD protection. It is suitable for designs constrained by space due to the compact TSSOP footprint. Verify that the 120 kbps maximum data rate meets system timing requirements before finalizing the bill of materials.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202 family of RS-232 transceivers. It shares functional compatibility with other variants such as MAX202CD and MAX202IDR, differing primarily in temperature ratings and package types. The CPW suffix specifically denotes the plastic thin-shrink small-outline package variant intended for surface-mount assembly.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible alternatives include MAX202CD and MAX202IDR. Verify that substitute parts meet the same thermal and electrical specifications. Cross-reference datasheets to ensure equivalent ESD protection levels and drive capabilities.
