MAX202CUE+

Drivers, Receivers, Transceivers Overview

The MAX202CUE+ is a +5V-powered, multichannel RS-232 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It features two drivers and two receivers for full-duplex communication with data rates up to 120kbps. The device operates on a single +5V supply using an integrated charge pump to generate ±10V internal levels. It requires four external 0.1µF capacitors for operation. The component is housed in a 16-pin TSSOP package and supports a supply voltage range of 4.5V to 5.5V.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for bipolar ±12V supplies
• Enables single +5V or 9V to +12V supply operation
• Maintains ±5V EIA/TIA-232E output signal levels at high data rates
• TTL/CMOS compatible inputs with internal pullup resistors

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'UE' against official documentation to confirm the TSSOP-16 package and commercial temperature range. Ensure the ordering part number matches the exact manufacturer designation to avoid discrepancies in pinout or electrical characteristics during procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring RS-232 interfaces powered solely by a +5V rail. It is suitable for applications where board space allows for four external 0.1µF capacitors. Consider the MAX203 or MAX205 if minimizing external component count is a priority.

Drivers, Receivers, Transceivers Part Context

The MAX202CUE+ belongs to the MAX200–MAX209 family of +5V RS-232 transceivers. This series is designed for EIA/TIA-232E and V.28/V.24 communications interfaces. The MAX202 variant specifically provides two drivers and two receivers, distinguishing it from other members like the MAX200 which offers five drivers.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include MAX202ESE+ and MAX202CWE+. These variants share identical electrical specifications but differ in package type (Narrow SOIC vs Wide SOIC) or temperature grade.
