_______________________________________________________________________________________

Note 1: Devices tested at +25°C. Overtemperature limits are guaranteed by design and not production tested.

Note 2: Parameter guaranteed by design.

ELECTRICAL CHARACTERISTICS (continued)

(VCC1 = VCC2 = 0.8V to 5.5V, GND = 0, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)
