What are the key features of MAX236EWG+?
- 4 RS-232 drivers and 3 tristatable Schmitt trigger receivers powered from a single 5 V supply with internal charge pump, eliminating external DC-DC converters
- Tristatable receiver outputs allow multiple MAX236EWG+ devices to share a common bus without bus contention in multi-drop serial communication designs
- 24-pin wide SOIC package with compliance to EIA-232-E, TIA-232-E, V.28, and V.24 standards ensures broad compatibility with legacy and modern serial interface equipment
What is MAX236EWG+ used for?
The MAX236EWG+ is widely used in microprocessor and DSP systems requiring multiple RS-232 serial ports for communication with modems, terminals, and industrial equipment operating over EIA-232 links from a single 5 V supply. Its 4-driver 3-receiver channel count suits multi-port serial communication boards in embedded controllers, industrial gateways, and legacy protocol bridges needing reliable RS-232 signal conversion. The device is also common in test and measurement instruments and point-of-sale terminals where compact 24-pin SOIC packaging integrates RS-232 interface circuitry without external charge pump capacitors exceeding 0.1 µF.

Frequently Asked Questions
How many RS-232 drivers and receivers does the MAX236EWG+ integrate, and what supply voltage does it require?
The MAX236EWG+ integrates 4 RS-232 drivers and 3 receivers, all powered from a single 5 V supply using an internal charge pump to generate the ±10 V RS-232 output swing. This eliminates the need for a separate ±12 V power rail, simplifying power supply design in embedded serial communication systems compliant with EIA-232-E and TIA-232-E standards.
What advantage do the tristatable receiver outputs of MAX236EWG+ offer in a multi-drop serial bus design?
The tristatable receiver outputs on the MAX236EWG+ allow the device's 3 receiver outputs to be placed in a high-impedance state when not addressed, preventing bus contention when multiple RS-232 interface ICs share a common parallel data bus. This feature is essential in multi-port serial communication designs where up to 4 MAX236EWG+ devices may share an 8-bit microprocessor data bus without requiring external bus buffers.
How do Schmitt trigger inputs improve noise immunity in MAX236EWG+ serial communication circuits?
The Schmitt trigger receiver inputs of the MAX236EWG+ provide hysteresis of approximately 0.5 V, preventing false output transitions caused by slow-rising RS-232 signal edges or noise on long cable runs exceeding 15 meters. This is particularly important in industrial environments where 50 Hz or 60 Hz interference can couple onto unshielded RS-232 serial lines, ensuring clean digital transitions at the 3-receiver outputs.
