MAX201EWE+T

Drivers, Receivers, Transceivers Overview

The MAX201EWE+T is a dual transmitter and dual receiver RS-232 transceiver designed for single +5V supply operation. It utilizes an integrated charge pump to generate the required ±10V internal voltages, eliminating the need for external bipolar supplies. The device supports data rates up to 120kbps and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a typical VCC power-supply current of 1mA and a V+ power-supply current of 5mA to 10mA. The output voltage swing is typically ±8V under load, with a maximum data rate of 120kbps. It features TTL/CMOS compatible inputs and outputs.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single +5V or +9V to +12V supply operation without external bipolar power sources.
• Drivers maintain ±5V EIA/TIA-232E output signal levels at data rates exceeding 120kbps.
• Requires only two 0.1μF external capacitors for charge-pump functionality, reducing board space requirements.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low power consumption
• Handheld devices with limited circuit board space
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing from distributors. Confirm RoHS compliance status through official manufacturer documentation or authorized supplier declarations. Ensure the operating temperature grade matches the 'E' designation for industrial ranges. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and authenticity before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require RS-232 communication but are constrained by a single +5V power rail. It is suitable for applications needing two independent transmit and receive channels. Consider the MAX201 over other family members if external bipolar supplies are unavailable and minimal external capacitance is preferred. Evaluate power consumption requirements against the typical 1mA VCC current draw.

Drivers, Receivers, Transceivers Part Context

The MAX201 belongs to the MAX200-MAX209/MAX211/MAX213 family of +5V RS-232 transceivers. This family shares common architecture including integrated charge pumps and EIA/TIA-232E compliance. Variations within the family differ in the number of drivers/receivers, shutdown capabilities, and package options. The MAX201 specifically offers a dual driver/dual receiver configuration optimized for standard serial communication interfaces.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX201CWE (commercial temperature range) or MAX201EPD (plastic DIP package). Other family members like the MAX202 or MAX209 may serve as functional alternatives if pinout differences are acceptable. Verify thermal performance and capacitor requirements when substituting.
