MAX3313EEUB+

Overview

The MAX3313EEUB+T is a low-power, single RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +4.5V to +5.5V supply and supports data rates up to 460kbps. The device integrates a single inverting charge pump requiring only three 0.1µF capacitors. It features ±15kV Human Body Model ESD protection on all I/O pins. A unique INVALID output asserts high when an active RS-232 signal is detected. The component is housed in a 10-pin µMAX package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated INVALID output signals host presence of active RS-232 communication
• Robust ±15kV Human Body Model ESD protection on transmitter outputs and receiver inputs
• Single charge-pump design reduces external component count to three capacitors
• Maintains RS-232-compatible voltage levels at maximum data rates

Applications

• Digital Cameras
• GPS Receivers
• Point-of-Sale (POS) Terminals
• Telecommunications Equipment
• Set-Top Boxes

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the extended industrial temperature range (-40°C to +85°C). Ensure the package type matches the required 10-pin µMAX footprint for PCB layout compatibility. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a single full-duplex RS-232 channel is required with minimal external capacitance. The INVALID pin provides hardware-level detection of cable connection status, eliminating software polling overhead. Choose this part over shutdown-capable variants if continuous receiver monitoring without power-down cycles is necessary for the application architecture.

Part Context

This device belongs to the MAX3311E/MAX3313E family of low-power, 5V EIA/TIA-232-compatible transceivers. While the MAX3311E includes a shutdown mode, the MAX3313E variant replaces the shutdown control with an INVALID output feature. Both share identical electrical characteristics regarding data rate, ESD protection, and power supply requirements.
