1.6 Electrical Characteristics
Unless otherwise specified, minimum and maximum
values are guaranteed by production testing.
Typical values are characteristic of the device at 25°C
and are the result of engineering evaluations. They are
provided for informational purposes only and are not
part of the manufacturing testing requirements.
Unless otherwise noted, all electrical specifications
are listed for T_A=25°C and V_CC = 3V to 5.5V.
