MAX202CDRE4

Drivers, Receivers, Transceivers Overview

The MAX202CDRE4 is a dual RS-232 line driver and receiver manufactured by Texas Instruments, designed for 5-V power supplies. It integrates charge pumps to generate positive and negative voltages from a single supply, eliminating the need for external transformers. 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 temperature range of -40°C to +85°C and is housed in a 16-pin SOIC package with a reel packaging format.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry generates required voltage levels without external inductors or transformers
• Provides robust ±15-kV ESD protection on transceiver inputs and outputs
• Supports full-duplex communication with two independent drivers and receivers
• Operates reliably across an extended industrial temperature range

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring reliable serial communication
• Modem interfaces in embedded devices
• Point-of-sale terminals and barcode scanners
• Medical equipment with serial data ports

Drivers, Receivers, Transceivers Procurement Notes

Verify the suffix RE4 indicates tape-and-reel packaging when sourcing. Confirm the component status remains active as discontinuation notices may vary by region. Ensure the SOIC-16 footprint matches the PCB design. Check RoHS compliance documentation for specific manufacturing dates. Validate supplier authenticity through authorized distribution channels.

Drivers, Receivers, Transceivers Selection Notes

Select this part for applications requiring dual RS-232 channels with high ESD tolerance. Compare against MAX202IDR if lower cost is prioritized over extended temperature range. Consider MAX202IPW for TSSOP-16 surface mount requirements. Verify capacitor selection matches the datasheet recommendations for stable charge pump operation. Ensure supply voltage stays within the 4.5-V to 5.5-V operating window.

Drivers, Receivers, Transceivers Part Context

The MAX202 series is a legacy line of RS-232 transceivers widely used in serial communication interfaces. The CDRE4 variant specifically denotes the commercial temperature grade version packaged in reels for automated assembly. This component serves as a standard interface solution for connecting microcontrollers to RS-232 peripherals in industrial and consumer electronics.

Drivers, Receivers, Transceivers Replacement Considerations

MAX202IDR is a direct pin-compatible alternative in SOIC-16 packaging. MAX202IPW offers the same functionality in a TSSOP-16 package. TRS202 provides equivalent performance from Texas Instruments. Verify electrical specifications and package dimensions before substitution.
