circuitry. These USB transceivers can also be powered by an externally regulated 3.3V supply
connected to both V
System-Side Power-Supply Input. Connect V
to GND with a 0.1µF (min) low-ESR ceramic capacitor.
Logic-Side Data Input/Output. SE0 operates as an input when OE is low and as an output when
OE is high. As an input, when SE0 is active high, D+ and D- are both driven low. As an output,
SE0 goes active high when both D+ and D- are low. (See Tables 3 and 4.)
Logic-Side Data Input/Output. DAT operates as an input for data on D+/D- when OE is low. DAT
operates as the output of the differential receiver on D+/D- when OE is high. (See Tables 3 and 4.)
No Connection. Leave N.C. unconnected. N.C. is not internally connected.
Suspend Input. Drive SUS low for normal transceiver operation. Drive SUS high for low-power
state.
USB Detector Output. A high on BD indicates that V
Output Enable. OE controls the USB transmitter outputs (D+/D-) and the interface signals (DAT,
SE0) when in USB mode. Drive OE high to operate D+/D- as inputs and to operate the logic
interface signals as outputs. Drive OE low to operate D+/D- as outputs and to operate the logic
interface signals as inputs.
Ground
Negative USB Differential Data Input/Output. D- is wired to the USB connector directly
(MAX13345E) or through a series resistor (MAX13342E). D- operates as an input when OE is high
and as an output when OE is low.
Positive USB Differential Data Input/Output. D+ is wired to the USB connector directly
(MAX13345E) or through a series resistor (MAX13342E). D+ operates as an input when OE is
high and as an output when OE is low.
Enumerate. Drive ENUM high to connect the internal 1.5kΩ resistor from D+ to V
low to disconnect the internal 1.5kΩ resistor.

GND with a 1µF ceramic capacitor.
