MUX
LVTTL Input
Selects Source for OUT, Selects Either IN0 (LOW) or IN1 (HIGH); defaults
HIGH when left open.
15
MUX1
LVTTL Input
Selects Source for OUT1. Selects Either IN (HIGH) or IN0 (LOW); defaults
HIGH when left open.
16
MUX0
LVTTL Input
Selects Source for OUT0. Selects either IN (LOW) or IN1 (HIGH); defaults
HIGH when left open.
