MAX14585AEVB+T

Overview

The MAX14585AEVB+T is a high-speed USB and audio switch IC featuring negative signal capability and high-voltage-tolerant VBUS detection. It integrates two independent DPDT switches within a QFN-Ultra-Thin-10 package. The device operates on a supply voltage ranging from 2.7 V to 5.5 V, with a maximum on-resistance of 6 Ohms. Switching times are specified at a maximum of 120 us for turn-on and 40 us for turn-off. The component supports a bandwidth of 960 MHz and draws only 7 uA in idle mode. It functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual DPDT switches for simultaneous USB and audio signal routing
• Provides high-voltage-tolerant VBUS detection for safe bus monitoring
• Supports negative signal capability to handle AC-coupled audio signals
• Features ultra-low quiescent current for power-efficient operation

Applications

• High-speed USB port switching and protection circuits
• Audio signal path switching in portable devices
• USB hub design implementations requiring bus isolation
• Mobile phone accessory connection management

Procurement Notes

Verify the exact suffix against the manufacturer's official datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the QFN-Ultra-Thin-10 package dimensions align with your PCB footprint constraints. Confirm RoHS compliance status through the latest environmental declaration provided by Analog Devices. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when designing systems requiring isolated USB and audio paths with minimal signal distortion. The low on-resistance ensures high-fidelity audio transmission while maintaining USB data integrity. Consider the small form factor for space-constrained mobile applications. Verify that the operating voltage range matches your system's power rails and that the thermal performance suits the intended enclosure environment.
