MAX3313EUB+

Overview

The MAX3313EUB+ is a low-power, +5V EIA/TIA-232-compatible transceiver featuring one transmitter and one receiver. It operates from a single +5V supply using a proprietary low-dropout output stage and a single inverting charge pump requiring only three 0.1µF capacitors. The device supports data rates up to 460kbps while maintaining RS-232-compatible output levels. It includes an INVALID output that asserts high when an active RS-232 cable signal is connected, signaling peripheral attachment. The component is housed in a 10-pin µMAX package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• INVALID Output for detecting active RS-232 cable connections
• Single Transceiver (1Tx/1Rx) configuration in a compact 10-Pin µMAX package
• RS-232-Compatible Operation with low-power design

Applications

• Digital Cameras
• PDAs
• GPS
• POS
• Telecommunications
• Handy Terminals
• Set-Top Boxes

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact temperature grade and packaging format. Ensure compatibility with the required voltage supply and interface standards before procurement. Cross-reference the manufacturer's current product status to confirm availability and lead times through authorized distribution channels.

Selection Notes

Select this component for applications requiring a single-channel RS-232 interface with minimal external capacitance. The INVALID pin provides a hardware mechanism to detect cable presence, which is useful for power management or connection status monitoring. Compare against the MAX3311 if shutdown functionality is needed instead of cable detection.

Part Context

The MAX3313 is part of the MAX3311-MAX3313 family of low-power, +5V EIA/TIA-232-compatible transceivers. These devices share a common architecture utilizing a single inverting charge pump and low-dropout transmitter output stage. The family differentiates primarily by feature sets, such as shutdown modes or invalid signal detection, while maintaining identical electrical performance and pin configurations.

Replacement Considerations

The MAX3311EUB+ is a pin-compatible alternative within the same family. It shares the same package and electrical characteristics but replaces the INVALID output with a 1µA shutdown mode. Verify if the host system requires cable detection or low-power shutdown to determine suitability.
