MAX203CWP+T

Drivers, Receivers, Transceivers Overview

The MAX203CWP+T is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply and includes an integrated charge pump to generate ±10V internally, eliminating the need for external bipolar supplies. The device features two drivers and two receivers in a 20-pin Wide SOIC package. It requires no external capacitors due to built-in integration. Electrical specifications include a maximum data rate of 120kbps, a typical VCC supply current of 15mA, and receiver input hysteresis of 0.5V. The operating temperature range is 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single-supply operation without external voltage converters.
• Built-in 0.1µF capacitors eliminate the need for external components, saving board space.
• Drivers maintain ±5V EIA/TIA-232E output levels at data rates exceeding 120kbps.
• Receiver inputs feature approximately 0.5V hysteresis for clean transitions with noisy signals.

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the component status as discontinued or obsolete through official manufacturer channels before procurement planning. Confirm that the 'T' suffix indicates tape-and-reel packaging if required for automated assembly processes. Ensure compliance with RoHS directives by checking the specific manufacturing batch documentation against regulatory standards.

Drivers, Receivers, Transceivers Selection Notes

Select this component when minimizing external passive components is critical for PCB layout density. The integrated capacitor design simplifies bill of materials and reduces overall system cost compared to discrete solutions. Verify that the 20-pin Wide SOIC package dimensions fit within the mechanical constraints of the target enclosure design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209 family of +5V RS-232 transceivers. Unlike other members requiring four external 0.1µF capacitors, the MAX203 integrates these directly onto the silicon die. This distinction allows for a more compact footprint while maintaining standard RS-232 signal integrity and drive capabilities defined by the EIA/TIA-232E specification.
