All voltages are referenced to ground.
Logic one voltages are specified at a source current of 1 mA.
Logic zero voltages are specified at a sink current of 4 mA.
I STBY , I CC specified with DQ, CLK/ CONV = V DD , and RST = GND.
Measured at V IH = 2.0V or V IL = 0.6V.
Measured at V OH = 2.4V or V OL = 0.4V.
Load capacitance = 50 pF.
t CWH must be 10 ms minimum following any write command that involves the E 2 memory.
250ns is the guaranteed minimum pulse width for a conversion to start; however, a smaller pulse
width may start a conversion.
10. Drift data is based on a 1000hr stress test at +125°C with V DD = 5.5V.
