TSSOP16
OE
113I
input for output enable (CMOS level with respect to VCC(I/O),
active LOW); enables the transceiver to transmit data on
the USB bus
RCV
224O
differential data receiver output (CMOS level with respect to
VCC(I/O)); driven LOW when input SUSPND is HIGH; the
output state of RCV is preserved and stable during an SE0
condition
VP
335O
single-ended D
+ receiver output (CMOS level with respect
to VCC(I/O)); for external detection of single-ended zero
(SE0), error conditions, speed of connected device; driven
HIGH when no supply voltage is connected to VCC(5.0) and
Vreg(3.3)
VM
446O
single-ended D
receiver output (CMOS level with respect
to VCC(I/O)); for external detection of single-ended zero
(SE0), error conditions, speed of connected device; driven
HIGH when no supply voltage is connected to VCC(5.0) and
Vreg(3.3)
SUSPND
557I
suspend input (CMOS level with respect to VCC(I/O)); a
HIGH level enables low-power state while the USB bus is
inactive and drives output RCV to a LOW level
MODE
6
I
mode input (CMOS level with respect to VCC(I/O)); a HIGH
level enables the differential input mode (VPO, VMO)
whereas a LOW level enables a single-ended input mode
(VO, FSE0). see Table 5 and Table 6
GND
6
8
-
ground supply
VCC(I/O)
779-
supply voltage for digital I/O pins (1.65 to 3.6 V). When
VCC(I/O) is not connected, the (D+, D) pins are in
three-state. This supply pin is totally independent of
VCC(5.0) and Vreg(3.3) and must never exceed the Vreg(3.3)
voltage.
SPEED
8
10
I
speed selection input (CMOS level with respect to VCC(I/O));
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)
D

11
AI/O
negative USB data bus connection (analog, differential); for
low-speed mode connect to pin Vpu(3.3) via a 1.5 k resistor
D
+

12
AI/O
positive USB data bus connection (analog, differential); for
full-speed mode connect to pin Vpu(3.3) via a 1.5 k resistor
VPO/VO

I
driver data input (CMOS level with respect to VCC(I/O),
Schmitt trigger); see Table 5 and Table 6
VMO/FSE0

14
I
driver data input (CMOS level with respect to VCC(I/O),
Schmitt trigger); see Table 5 and Table 6
