MAX202ICSE+T

Drivers, Receivers, Transceivers Overview

The MAX202ICSE+T is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates two drivers and two receivers within a 16-SOIC surface-mount package. The device operates on a single +4.5V to +5.5V supply and supports data rates up to 120Kbps. Each driver output and receiver input provides ±15kV electrostatic discharge (ESD) protection without latch-up. The circuit utilizes four external 0.1µF capacitors for charge pumping, reducing board space compared to larger capacitor requirements in other series devices.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ESD protection of ±15kV on all inputs and outputs
• Single +5V power supply operation with internal charge pump
• Compact design requiring only 0.1µF external capacitors
• Compliance with EIA/TIA-232E and CCITT V.28 standards

Drivers, Receivers, Transceivers Applications

• RS-232 communication interfaces in industrial equipment
• Modems and portable instruments
• Communications systems requiring robust ESD protection

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature range (-40°C to +85°C) as per the manufacturer's part numbering system. Confirm the '+T' suffix denotes tape-and-reel packaging rather than tube packaging. Ensure the component source is an authorized distributor to guarantee authenticity and traceability.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring dual-channel RS-232 connectivity with high ESD immunity. It is suitable for applications where board space is limited due to its small 0.1µF capacitor requirement. Compare against the MAX232 series if higher drive strength or different pin configurations are needed, noting that the MAX202 uses smaller capacitors.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E-MAX241E family of RS-232 transceivers designed for harsh environments. The 'I' suffix typically specifies the extended industrial temperature range, while 'CSE' indicates the narrow SOIC package. The 'MAX202' base model distinguishes it from variants like MAX232 which may have different pinouts or capacitor requirements.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX202ECSE+T is a direct equivalent with commercial temperature range. For wider temperature operations, the MAX202IESE+ is available. Other family members like MAX232ECSE+ offer similar functionality but may require different external components or pin mappings.
