MAX3387ECUG+T

Overview

The MAX3387ECUG+T is a 3V-powered RS-232 transceiver featuring three receivers and three transmitters. It operates on a +3.0V to +5.5V supply with a guaranteed data rate of 250kbps. The device includes AutoShutdown Plus, reducing supply current to 1µA when idle. ESD protection reaches ±15kV (Air-Gap) and ±8kV (Contact). It utilizes a dual charge pump requiring four 0.1µF capacitors for operation at +3.3V. The component is housed in a 24-pin TSSOP package.

Feature Summary

• AutoShutdown Plus technology reduces power consumption by shutting down internal charge pumps during inactivity.
• Integrated V_L pin enables compatibility with mixed-voltage logic systems ranging from 1.8V to 5.5V.
• Robust electrostatic discharge protection ensures reliability against high-voltage static events.

Applications

• Subnotebook and Palmtop Computers
• PDAs and PDA Cradles
• Cell Phone Data Cables

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube. Confirm the 'E' designation matches the -40°C to +85°C industrial temperature range. Ensure the '+'' suffix confirms lead-free and RoHS compliance status before finalizing procurement orders.

Selection Notes

Select this component for applications requiring low-power RS-232 communication in portable devices. The separate V_L pin allows direct interfacing with 1.8V or 3.3V logic without level shifters. Verify that the required data rate does not exceed 250kbps and that the system can accommodate the necessary external charge-pump capacitors.

Part Context

This part belongs to the MAX3387E family of RS-232 transceivers designed for battery-powered equipment. It shares functional similarities with the MAX3386 but offers an additional transmitter for ring indicator signals. The device is manufactured using BiCMOS process technology within the Maxim Integrated product line.
