Negative current is defi ned as coming out of (sourcing) the specifi ed device terminal.
Typical data is is for design information only and is at T
A
= +25°C.
* Operation at a clock frequency greater than the specifi ed minimum is possible but not warranteed.
ELECTRICAL CHARACTERISTICS at T
A
= +25°C (A6812S-) or over operating tem per a ture range (A6812E- or
A6812K-), V
BB
= 60 V; un less otherwise noted
