±15kV ESD-Protected USB Transceivers with
External/Internal Pullup Resistors
General Description
The MAX13481E/MAX13482E/MAX13483E ±15kV ESD-
protected USB-compliant transceivers interface low-
voltage ASICs with USB devices. The transceivers fully
comply to USB 2.0 when operating at full-speed
(12Mbps). The transceivers also operate with V
L
as low
as 1.6V, ensuring compatibility with low-voltage ASICs.
The MAX13481E/MAX13482E/MAX13483E feature a
logic-selectable suspend mode that reduces current
consumption. Integrated ±15kV ESD circuitry protects
D+ and D- bus connections.
The MAX13481E/MAX13482E/MAX13483E operate over
the extended -40°C to +85°C temperature range and are
available in a 16-pin (3mm x 3mm) thin QFN package.

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.
