MAX202CWE+T

Drivers, Receivers, Transceivers Overview

The MAX202CWE+T is a +5V-powered, multichannel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features two drivers and two receivers operating in full duplex mode within a 16-pin SOIC package. The device supports data rates up to 120kbps with a typical propagation delay of 1µs. It operates on a single supply voltage ranging from 4.5V to 5.5V, drawing a maximum power-supply current of 15mA. The component functions within an industrial temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for external bipolar ±12V supplies, enabling operation from a single +5V source.
• Drivers maintain ±5V EIA/TIA-232E output signal levels at data rates exceeding 120kbps under standard loading conditions.
• Receiver inputs feature guaranteed thresholds that are tighter than EIA/TIA-232E specifications, improving noise margins and ensuring compatibility with TTL/CMOS logic levels.

Drivers, Receivers, Transceivers Applications

• EIA/TIA-232E and V.28/V.24 communications interface applications
• Battery-powered equipment requiring single-supply operation
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status through manufacturer certificates. Ensure the component matches the required pin configuration for the target PCB layout. Validate that the selected variant meets the environmental operating conditions of the final assembly.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring two-channel RS-232 communication without complex external power generation. The integrated charge pump simplifies board space requirements compared to older transceivers. Verify that the application load capacitance remains within limits to sustain the specified 120kbps data rate. Consider the 16-pin SOIC footprint during mechanical design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209 family of +5V RS-232 transceivers. The MAX202 specifically provides two drivers and two receivers, distinguishing it from variants like the MAX200 (five drivers) or MAX201 (two drivers/receivers but different supply requirements). The 'C' designation indicates the commercial temperature range, while 'W' denotes the wide small-outline package.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include MAX202CSE+T and MAX202ECWE+T. These alternatives share the same functional architecture and pinout but may differ in temperature rating or packaging style. Verify electrical characteristics match the original design requirements before substitution.
