MAX202IPWR

Drivers, Receivers, Transceivers Overview

The MAX202IPWR is a dual RS-232 line driver and receiver manufactured by Texas Instruments, designed for single-supply operation. It integrates two drivers and two receivers within a TSSOP-16 package, supporting full-duplex communication at data rates up to 120 kb/s. The device operates on a single 5 V supply voltage, with an acceptable range of 4.5 V to 5.5 V, and draws a typical operating current of 15 mA. It features integrated charge pumps requiring only four small external capacitors to generate the necessary ±VCC voltages for RS-232 signaling. The component provides robust protection against electrostatic discharge, rated at ±15 kV according to the Human Body Model specification.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual drivers and dual receivers for complete RS-232 transceiver functionality in a compact surface-mount package.
• Includes internal charge pump circuitry that eliminates the need for external dual-voltage power supplies.
• Provides high-level electrostatic discharge protection on all pins to safeguard connected serial interfaces.

Drivers, Receivers, Transceivers Applications

• Connecting asynchronous communication controllers to serial port connectors.
• Point-to-point communication links between microcontrollers and PC serial ports.
• Industrial control systems requiring reliable RS-232 connectivity.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'IPWR' indicates the TSSOP-16 package and tape-and-reel packaging format. Confirm RoHS compliance status through official manufacturer documentation or certified distributor declarations. Ensure the source is an authorized channel to guarantee authenticity, as counterfeit components may exhibit degraded ESD performance or incorrect electrical parameters.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a low-pin-count solution is required for dual-channel RS-232 communication. It is suitable for designs constrained by space, offering a smaller footprint compared to traditional SOIC packages. Verify that the system environment supports the industrial temperature range if extreme conditions are expected, and ensure adequate decoupling capacitors are placed near the power pins for stable charge pump operation.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202 family of RS-232 transceivers from Texas Instruments. It shares functional compatibility with other variants such as the MAX202IDWR (SOIC package) and MAX202IPW (tube packaging). The IPWR suffix specifically denotes the TSSOP-16 form factor and reel-based distribution method, distinguishing it from through-hole or different surface-mount alternatives within the same product line.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes include the MAX202IDWR for SOIC-16 applications and the TRS202E. Verify that alternative devices maintain the same 120 kb/s data rate and ±15 kV ESD protection levels to ensure interface reliability without redesigning the PCB layout.
