Symbol
Pin Type Description
MODE
1
I
driver interface selection input (Schmitt trigger):
LOW: Philips Encoded Data Interface (pins VO, FSE0)
HIGH: USB-IF Standard Data Interface (pins VPO, VMO);
pulled HIGH by an internal pull-up transistor, if left floating
OE
2
I
output enable input (Schmitt trigger, active LOW); enables the
transceiver to transmit data on the bus
RCV
3
O
differential data receiver output (CMOS level); driven HIGH
when input SUSPND is HIGH; the output state of RCV is
preserved and stable during an SE0 condition
VP
4
O
single-ended D+ receiver output (CMOS level); used for
external detection of single-ended zero (SE0), error
conditions, speed of connected device
VM
5
O
single-ended D− receiver output (CMOS level); used for
external detection of single-ended zero (SE0), error
conditions, speed of connected device
SUSPND
6
I
suspend input (Schmitt trigger); a HIGH level enables
low-power state while the USB bus is inactive and drives
output RCV to a HIGH level
GND
7
-
ground supply
n.c.
8
-
not connected
SPEED
9
I
speed selection input (Schmitt trigger); adjusts the slew rate
of differential data outputs D+ and D− according to the
transmission speed:
LOW: low-speed (1.5 Mbit/s)
HIGH: full-speed (12 Mbit/s)
