MAX3313CUB

Overview

The MAX3313CUB is a single RS-232 transceiver in a 10-pin µMAX package, designed for +5V operation. It supports data rates up to 460kbps with a typical supply current of 250µA and features an INVALID output that asserts high when active RS-232 signals are detected. The device utilizes a single charge pump requiring three 0.1µF capacitors. Operating temperature range is 0°C to +70°C.

Feature Summary

• INVALID signal output for port connection detection
• Single charge pump voltage conversion
• RS-232-compatible driver and receiver

Applications

• Digital Cameras
• PDAs
• GPS
• POS
• Telecommunications

Procurement Notes

Verify the specific ordering suffix 'CUB' against official Maxim Integrated documentation to confirm the commercial temperature range (0°C to +70°C) and 10-pin µMAX package configuration. Ensure compatibility with +5V power supplies and check for any lead-free or RoHS compliance updates in the latest datasheet revisions before procurement.

Selection Notes

Select this component for applications requiring low pin count and minimal external capacitance for RS-232 communication at +5V. The MAX3313 variant is preferred over the MAX3311 when host system notification of peripheral cable connection is required via the INVALID output signal.

Part Context

This part belongs to the MAX3311/MAX3313 family of low-power, +5V EIA/TIA-232-compatible transceivers manufactured by Maxim Integrated Products. The family differentiates between models based on shutdown capabilities and the presence of the INVALID output feature.
