MAX3232ECUP+

Overview

The MAX3232ECUP+T is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 3V to 5.5V supply and supports data rates up to 250kbit/s with a driver slew rate of 30V/μs. The device integrates two drivers and two receivers, utilizing a dual charge-pump circuit that requires only four external 0.1μF capacitors. It features ±15kV IEC ESD protection on serial-port connection pins and meets TIA/EIA-232-F standards. The component is housed in a 16-pin TSSOP package.

Feature Summary

• Battery-powered portable devices

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Confirm RoHS compliance status and lead finish details directly with the supplier or official datasheet before procurement. Ensure the source document matches the specific part number variant to avoid discrepancies in packaging or electrical characteristics.

Selection Notes

Select this component when designing interfaces requiring dual RS-232 channels within a compact surface-mount footprint. It is suitable for applications needing robust ESD protection and low standby current. Verify that the system voltage falls within the 3V to 5.5V range and that the required data rate does not exceed 250kbit/s. Consider pin-compatible alternatives if higher speeds are necessary.

Part Context

This device belongs to the MAX3232E family of multichannel RS-232 line drivers and receivers. It is designed to provide electrical interface between asynchronous communication controllers and serial-port connectors. The series is widely used in industrial and commercial applications requiring reliable serial communication over standard RS-232 cables.

Replacement Considerations

The SNx5C3232 is a pin-compatible alternative offering 1Mbit/s data rates. Verify compatibility regarding package dimensions and electrical parameters before substitution.
