MAX201EWE

Drivers, Receivers, Transceivers Overview

The MAX201EWE is a dual RS-232 transceiver designed for single +5V supply operation. It features two drivers and two receivers with full duplex communication capability. The device utilizes an integrated charge pump to generate ±10V internal supplies from the +5V input, requiring only four external 0.1µF capacitors. It supports data rates up to 120kbps and operates within a temperature range of -40°C to +85°C. The unit is housed in a 16-pin Wide SO package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for bipolar ±12V power supplies
• Enables single +5V or +9V to +12V supply operation
• Requires only four external 0.1µF capacitors for voltage conversion

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment
• Handheld devices
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status directly with the supplier documentation. Ensure the component matches the exact pinout and electrical specifications required for the target interface design before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring dual RS-232 channels with minimal external capacitance. It is suitable for applications where space constraints limit the use of larger capacitors. Verify that the system power supply remains stable between +5V and +13.2V to ensure proper charge pump operation and signal integrity across the operating temperature range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209 family of +5V RS-232 transceivers. Unlike the MAX202 which requires four capacitors, the MAX201 uses only two due to its simplified voltage conversion architecture. It shares the same 16-pin Wide SO footprint as other members of the series but differs in internal driver/receiver configuration and capacitor requirements.
