Product details

RS-232 link with 500 mV hysteresis margin

The MAX232ECDW is a dual-driver, dual-receiver RS-232 transceiver from Texas Instruments' MAX232E family, handling full-duplex serial communication at up to 250 kbps. The 500 mV receiver hysteresis filters noise on the incoming line, reducing the chance of false edges on long cable runs in industrial or commercial environments.

16-SOIC footprint and board-fit note

The surface-mount package suits reflow soldering; no special thermal pad or exposed paddle is needed.

Frequently asked questions

Where can I buy MAX232ECDW and how do I get a price?

Sourced to order through authorized and independent distribution.

What is the closest pin-compatible alternative to MAX232ECDW in this Interface & Transceivers family?

The MAX232ECDW is a standard MAX232E variant in the wide-body SOIC-16 package. Any pin-compatible RS-232 transceiver in the same package and supply range must match the 2/2 driver/receiver count and 5 V-only supply — the MAX232 family's internal charge pump eliminates the need for external ±12 V rails.

What is MAX232ECDW's listed type (Transceiver) on this Interface & Transceivers line?

The listed type is Transceiver, full duplex, with 2 drivers and 2 receivers.

What is MAX232ECDW's listed duplex (Full) on this Interface & Transceivers line?

Full duplex — both driver and receiver pairs operate simultaneously, supporting bidirectional RS-232 communication on two channels.

What compliance documentation does Texas Instruments provide for MAX232ECDW (RoHS, REACH, UL, IEC)?

Texas Instruments certifies ROHS3 compliance for the MAX232ECDW. REACH, UL, and IEC documentation should be verified against the latest TI compliance reports for the specific date code.
