Pin Function
System Interface Supply Voltage (Input): Determines logic voltage levels for
system interface signaling to logic controller.
Speed (Input): Edge rate control. Logic high selects full-speed edge rates.
Logic low selects low-speed edge rates.
Receive Data (Output): System interface receive data interface to logic
controller.
Plus (Input/Output): System interface signal to logic controller. If OE# is
logic 1, VP is a receiver output (+); If OE# is logic 0, VP is a driver input (+).
Minus (Input/Output): System interface signal to logic controller. If OE# is
logic 1, VM is a receiver output (–); If OE# is logic 0, VM is a driver input (–).
Not internally connected.
Ground: Power supply return and signal reference.
Suspend (Input): Logic high turns off internal circuits to reduce supply
current.
Output Enable (Input): Active-low system interface input signal from logic
controller. Logic low causes transceiver to transmit data onto the bus. Logic
high causes the transceiver to receive data from the bus.
USB Differential Data Line – (Input/Output)
USB Differential Data Line + (Input/Output)
Termination Supply (Output): 3.3V speed termination resistor supply output.
USB Supply Voltage (Input): Transceiver supply.
