Table 3. Transmit Truth Table
The MAX13342E/MAX13345E transmit USB data to the
USB differentially on D+ and D- when OE is low. The
D+ and D- outputs are determined by SE0 and DAT
(see Table 3).
Drive OE high and SUS low to receive data on D+/D-.
Differential data received on D+ and D- appear at DAT.
SE0 goes high only when both D+ and D- are low
(Table 4).
The MAX13342E provides low internal resistance on
D+/D-. Two external series resistors for impedance
matching are required for USB. Place the resistors in
between the MAX13342E and the USB connector (see
Figure 2).
