MAX3313EEUB

Overview

The MAX3313EEUB is a low-power, single-channel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +5V supply and supports data rates up to 460kbps. The device integrates one transmitter and one receiver within a 10-pin µMAX package. Key electrical parameters include a supply voltage range of 4.5V to 5.5V, typical supply current of 250µA, and ±15kV ESD protection on I/O pins per the Human Body Model. It functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Features an INVALID output pin that asserts high when active RS-232 cable signals are detected, indicating peripheral connection status.
• Incorporates proprietary low-dropout transmitter output stages for RS-232-compatible operation using only three external capacitors.
• Provides robust ±15kV electrostatic discharge (ESD) protection on all transmitter outputs and receiver inputs.

Applications

• Digital Cameras
• GPS Systems
• Point-of-Sale (POS) Terminals

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact temperature grade and packaging configuration. Ensure compatibility with system requirements regarding the 10-pin µMAX footprint and single charge-pump capacitor design before finalizing procurement.

Selection Notes

Select this component for applications requiring minimal external capacitance and robust ESD tolerance in compact designs. The MAX3313E variant is specifically chosen over the MAX3311E when the INVALID signal detection feature is required for port monitoring, while maintaining identical electrical performance and power characteristics.

Part Context

This part belongs to the MAX3311E/MAX3313E family of low-power, 5V EIA/TIA-232-compatible transceivers. These devices are designed for portable electronics where space and power consumption are critical constraints, offering full duplex communication in a small form factor without requiring negative supply rails.
