MAX201CWE+

Drivers, Receivers, Transceivers Overview

The MAX201CWE+ is a dual-driver, dual-receiver RS-232 transceiver designed for single +5V supply operation. It features an integrated charge pump that generates the necessary ±10V levels from a +5V input and an external +9V to +13.2V V+ supply. The device requires two 0.1µF external capacitors for voltage conversion. It supports data rates up to 120kbps with full duplex communication. Operating within a commercial temperature range of 0°C to +70°C, it utilizes a 16-pin Wide SO package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for bipolar ±12V supplies
• Enables single supply operation using +5V and +9V to +13.2V inputs
• Maintains ±5V EIA/TIA-232E output signal levels at high data rates

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status and check for obsolescence notices prior to procurement. Ensure ordering suffixes match required packaging and temperature grades. Request original manufacturer documentation to validate specifications against counterfeit risks.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 interface is required without shutdown functionality. Unlike the MAX202, the MAX201 utilizes only two external capacitors by leveraging an existing +9V to +13.2V supply rail. Choose this part over the MAX203 if external capacitor count must be minimized but a secondary positive voltage rail is available.

Drivers, Receivers, Transceivers Part Context

The MAX201 belongs to the MAX200-MAX209 family of +5V RS-232 transceivers. This series integrates charge pumps to simplify system design by removing external inverting regulators. The MAX201 specifically targets applications where a secondary positive voltage is present, reducing the external component count compared to standard four-capacitor solutions.
