Note 1:
Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are 100% tested
at T
A
= +25°C.
Note 2:
Currents into the device are positive, and current out of the device is negative. All voltages are referenced to ground except
V
OD
.
Note 3:
Guaranteed by correlation data.
Note 4:
AC parameters are guaranteed by design and characterization.
Note 5:
C
L
includes probe and jig capacitance.
