±15kV ESD-Protected USB Transceivers with
External/Internal Pullup Resistors
The MAX13481E/MAX13482E/MAX13483E ±15kV ESD-
protected USB-compliant transceivers convert single-
ended or differential logic-level signals to USB signals,
and USB signals to single-ended or differential logic
signals. These devices fully comply to USB 2.0 when
operating at full-speed (12Mbps), and operate with V
as low as 1.6V, ensuring compatibility with low-voltage
ASICs. Integrated ±15kV ESD-circuitry protection pro-
tects D+ and D- bus connections.
The MAX13481E/MAX13483E require an external 1.5kΩ
pullup resistor to V
MAX13481E requires an external 1.5kΩ pullup resistor
and feature an active-low enumeration function that
connects a +3.3V voltage at VPU. The MAX13482E fea-
tures an active-low enumeration function that connects
a 1.5kΩ pullup resistor at VPUR for full-speed opera-
tion. The MAX13482E/MAX13483E also provide a bus
detect (BD) output that asserts high when V
