MAX3380ECUP+

Overview

The MAX3380ECUP+ is a +2.35V to +5.5V-powered EIA/TIA-232 and V.28/V.24 communication interface featuring two receivers and two transmitters. It operates at data rates up to 460kbps with ±15kV ESD protection on all CMOS and RS-232 inputs and outputs. The device utilizes AutoShutdown Plus technology to achieve a 1µA shutdown current when no valid signal transitions are detected for 30 seconds. A dedicated VL pin allows logic levels down to +1.65V, ensuring compatibility with mixed-voltage systems. It is housed in a 20-pin TSSOP package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• AutoShutdown Plus feature automatically reduces supply current to 1µA after 30 seconds of inactivity
• Proprietary low-dropout transmitter output stage enables true RS-32 performance from +3.1V to +5.5V
• Integrated dual-mode regulated charge-pump voltage converter requires only four small capacitors
• Dedicated VL pin sets CMOS logic thresholds and outputs for compatibility with cell phone logic supply voltages

Applications

• Cell Phone Data Lump Cables
• PDA Data Lump Cables
• GPS Receivers
• Digital Cameras

Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) rather than the extended industrial range (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring high data rates up to 460kbps while maintaining low power consumption. The integrated charge pump eliminates external voltage generation requirements. Ensure the system logic voltage aligns with the VL pin specification for proper threshold referencing.

Part Context

This part belongs to the MAX3380E/MAX3381E family of RS-232 transceivers designed for portable devices. The MAX3380 variant supports higher data rates compared to the MAX3381. Both variants share identical packaging and core features, differing primarily in maximum guaranteed baud rate capabilities.
