Description

HBCC16

HVQFN14

input for output enable (CMOS level with respect to VCC(I/O), active LOW);

enables the transceiver to transmit data on the USB bus

input pad; push pull; CMOS

RCV

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

output pad; push pull; 4 mA output drive; CMOS

VP/VPO

I/O

single-ended D+ receiver output VP (CMOS level with respect to VCC(I/O));

for external detection of SE0, error conditions, speed of connected device;

this pin also acts as the drive data input VPO; see Table 3 and Table 4

bidirectional pad; push-pull input; three-state output; 4 mA output drive;

CMOS

VM/VMO

I/O

single-ended D

− receiver output VM (CMOS level with respect to VCC(I/O));

for external detection of SE0, error conditions, speed of connected device;

this pin also acts as the drive data input VMO; see Table 3 and Table 4

bidirectional pad; push-pull input; three-state output; 4 mA output drive;

CMOS

SUSPND

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

input pad; push pull; CMOS
