MAX202ECSE+TG068

Drivers, Receivers, Transceivers Overview

The MAX202ECSE+TG068 is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates two drivers and two receivers within a 16-pin narrow SO package. The device operates on a single +4.5V to +5.5V supply, utilizing an internal charge pump to generate the required ±10V levels for RS-232 signaling. It supports data rates up to 120kbps and features high electrostatic discharge protection of ±15kV (Human Body Model). The component is rated for an operating temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for external bipolar power supplies.
• High ±15kV ESD protection on driver outputs and receiver inputs ensures reliability in harsh environments.
• CMOS/TTL-compatible input thresholds allow direct interfacing with standard logic families.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low-power serial communication
• Hand-held diagnostic tools
• Portable instrumentation systems

Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific suffix 'TG068' corresponds to the intended tape-and-reel packaging variant rather than the tube-packaged MAX202ECSE. Confirm the commercial temperature grade (0°C to +70°C) aligns with system requirements, as industrial variants exist. Ensure the ordering information matches the exact pinout and electrical specifications defined in the official datasheet.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a compact 16-pin solution is required for dual-channel RS-232 communication. It is suitable for designs constrained by board space due to its integrated charge pump. Consider the commercial temperature range limits; if operation below 0°C is necessary, verify availability of the EE-series equivalent. Ensure adequate decoupling capacitors are placed near VCC and charge pump terminals.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E-MAX213E family of RS-232 transceivers. These devices share common architecture but differ in channel counts, package types, and control features like shutdown modes. The MAX202E specifically provides a basic 2-driver/2-receiver configuration without enable or shutdown pins, distinguishing it from more complex members like the MAX211E or MAX213E.
