±15kV ESD-Protected USB Transceivers

±15kV ESD-Protected USB Transceivers

Please check latest availability status for a specific part variant.


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 VL as low as +1.65V, ensuring compatibility with low-voltage ASICs.

The MAX3450E/MAX3451E/MAX3452E feature a logic-selectable 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 bus-detect (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.
