MAX13342E/MAX13345E
3-Wire Interface Full-Speed USB Transceivers
With/Without Internal Series Resistors
_______________________________________________________________________________________

Interface
The MAX13342E/MAX13345E control signals are used
to control the USB D+/D- lines. VL powers the logic-
side interface and sets the input and output thresholds
of these signals. The control signals for the MAX13342E
and MAX13345E are DAT, SE0, and
OE.
Power-Supply Configuration
Normal Operating Mode
See Table 1 for various power-supply configurations.
VBUS supplies power to the USB transceivers. Connect
VBUS to a +4V to +5.5V supply. Connect VL to a +2.3V
to +3.6V supply. VBUS is typically connected directly to
the USB connector. An internal regulator provides 3.3V
to internal circuitry, and a regulated 3.3V output at
VTRM, in addition to powering the internal D+ pullup
resistor. The MAX13342E and MAX13345E can be
powered by connecting both VBUS and VTRM to a 3.3V
external regulator.
Low-Power Mode
Operate the transceivers in low-power mode by assert-
ing SUS high. In low-power mode, the USB differential
receiver is turned off and VBUS consumes less than
45A of supply current. The single-ended D+ and D-
receivers are still active when driving SUS high.
Sharing Mode
Connect VL to a system power supply and leave VBUS
(or VBUS and VTRM) unconnected or connected to
GND. D+ and D- are tri-stated, allowing other circuitry
to share the USB D+ and D- line. VL consumes less
than 5A of supply current. When operating the trans-
ceivers in sharing mode, the SUS input is ignored, and
the interface signals (SE0, DAT) are high impedance.
Disable Mode
Connect VBUS to a system power supply and leave VL
unconnected or connect to ground. In disable mode,
D+ and D- are tri-stated, and VBUS and/or VTRM (or
VBUS and VTRM) consume less than 25A. When oper-
ating the transceivers in disable mode,
OE, SUS, and
inputs to the interface control signals are ignored.
