Digital input voltage must not
exceed supply voltage or go
below –0.5V ; “0” <0.8V;
All strobes are level triggered.

Using the internal feedback
resistor and an external op
amp.
At 25 C; the output leakage
current will create an offset
voltage at the external op amps
output. It doubles every 10 C
temperature increase.
