19-3801; Rev 2; 1/06
1ꢀ5k EꢁDꢂ-rotected UꢁB Transceivers with
External/Internal -ullup Resistors
General Description
Features
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
♦ Active-Low Enumeration Input Controls D+ Pullup
Resistor (MAX13482E)
♦ Active-Low Enumeration Input Controls Internal
Pullup Switch (MAX13481E)
(12Mbps). The transceivers also operate with V as low
L
♦
15kV ESD Protection on D+ and D-
♦ USB 2.0 Full-Speed Compliant Transceiver
♦ V Detection (MAX13482E/MAX13483E)
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.
