MAX3232ECUP+TG071

Overview

The MAX3232ECUP+TG071 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. The device integrates two drivers and two receivers with ±15kV IEC ESD protection on serial-port connection pins. It requires four external 0.1μF capacitors for the charge pump circuit. The component is housed in a 16-pin TSSOP package (PW) measuring 5mm x 6.4mm. Operating temperatures range from -40°C to +85°C, with a typical standby current of 300μA.

Procurement Notes

Verify the specific suffix TG071 against official manufacturer documentation to confirm exact packaging configuration and lot traceability. Confirm that the component meets all required automotive or industrial qualification standards for your specific deployment environment before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring dual RS-232 channels with robust ESD protection. Ensure the design accommodates four external 0.1μF capacitors for the internal charge pump. Verify that the 250kbit/s maximum data rate satisfies the communication requirements of the target application interface.

Part Context

This part belongs to the MAX3232E family of low-power RS-232 line drivers and receivers. It provides a complete solution for converting TTL/CMOS logic levels to RS-232 voltages. The device is designed to replace older generation transceivers while offering improved ESD immunity and lower power consumption suitable for modern embedded applications.

Replacement Considerations

The SNx5C3232 is identified as a pin-compatible alternative high-speed device supporting 1Mbit/s operation. Catalog versions such as MAX3232E are available as standard non-automotive equivalents.
