Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX3450E/MAX3451E/MAX3452E USB-compliant transceivers interface low-voltage ASICs with USB devices. The devices fully comply with USB 1.1 and USB 2.0 when operating at full (12Mbps) and low (1.5Mbps) speeds. The MAX3450E/MAX3451E/ MAX3452E operate with V_L as low as +1.65V, ensuring compatibility with low-voltage ASICs.

The MAX3450E/MAX3451E/MAX3452E feature a logicselectable suspend mode that reduces current consumption to less than 40µA. Integrated ±15kV ESD protection protects the USB D+ and D- bidirectional bus connections. The MAX3450E is pin compatible with Micrel's MIC2550A. The MAX3451E features an internal 1.5kΩ USB pullup resistor and an enumeration function that allows devices to logically disconnect while plugged in. The MAX3452E provides a push-pull busdetect (BD) output that asserts high when VBUS is greater than +4.0V.

The MAX3450E/MAX3451E/MAX3452E operate over the -40°C to +85°C extended temperature range and are available in 14-pin TSSOP and 3mm x 3mm 16-pin thin QFN packages.
