Decoder/demultiplexer U2
Table 10
Truth table for first input of U2
Thus, it can be seen by comparing column 3 (input 1A) and column 5 (output Y1), that the
USBOE signal is getting inverted.
Table 11
Truth table for second input of U2
Thus, it can be seen by comparing column 3 (input 2A) and column 4 (output Y0), that the
SUS signal is getting buffered. Hence only the voltage level conversion from 5 V to 3.3 V is
done.
Decoder/demultiplexer U3
The first input and other related input pins are not connected in this decoder.
