USB Transceivers, with Low VIO 3/5-Wire Interface
To transmit data to the USB, operate the MAX14582 in
USB mode (see the
and drive OE low. The MAX14582 transmits data to the
USB differentially on D+ and D-. VP and VM serve as differ-
ential input signals to the driver. When VP and VM are both
driven low, a single-ended zero (SE0) is output on D+/D-.
To receive data from the USB, operate the MAX14582 in
USB mode (see the
Drive OE high and SUS low. Differential data received at
D+/D- appears as a logic signal at RCV. VP and VM are
the outputs of single-ended receivers on D+ and D-.

As a host USB transceiver, the MAX14581/MAX14582
require external 15kI pulldown resistors and connecting

The MAX14581/MAX14582 feature ±15kV (HBM) ESD
protection on D+ and D-. The ESD structures withstand
high ESD in all states: normal operation, suspend, shar-
ing mode, disable mode, and powered down. V

for protection to the following limits:
