Thus it can be seen by comparing column 3 (input 1A) and column 4 (output Y0), that the
CON signal is getting buffered. Hence only the voltage level conversion from 5 V to 3.3 V is
done.
Truth table for second input of U3
Second input of U3 is not used in the application. However, to save the current consumption,
these inputs are not left floating and are tied to ground.

Edge rate control. A logic HIGH operates at edge rates for “full-speed”
operation. A logic LOW operates edge rates for “low-speed” operation.
Receive data. Output for USB differential data.
If OE# = H, VP = receiver output (+)
If OE# = L, VP = driver input (+)
If OE# = H, VM = receiver output (-)
If OE# = L, VM = driver input (-)
CONNECT (input). Controls state of VPU. Refer to VPU pin description for
details.
Ground reference
Suspend (active-high). Turns off internal circuits to reduce supply current.
Not connected
Output enable (active-low). Enables transceiver data transmission to the
bus.
When not active, the transceiver is in the receive mode.
Differential data lines.
3.3 V reference supply output. Requires a 1.0 µF decoupling capacitor for
stability.
