ELECTRICAL CHARACTERISTICS (continued)
VDD = 2.5V to 5.5V, VPP = GND, VH = VDD, VL = GND, TA = -40°C to +85°C, unless otherwise noted. Typical values
are at VDD = 5.0V, TA = +25°C, unless otherwise noted.(1)

Notes:
(1) All devices are production tested at TA = +25°C and are guaranteed by design for TA = -40°C to +85°C.
(2) Digital timing is guaranteed by design, not production tested.
(3) Power-up time is the period of time from when the power supply is applied until the serial interface is ready for writing.
