NOTES:
1. All voltages are referenced to ground.
2. Logic one voltages are specified at a source current of 1 mA.
3. Logic zero voltages are specified at a sink current of 4 mA.
4. ISTBY, ICC specified with DQ, CLK/ CONV = VDD, and RST = GND.
5. Measured at VIH = 2.0V or VIL = 0.6V.
6. Measured at VOH = 2.4V or VOL = 0.4V.
7. Load capacitance = 50 pF.
8. tCWH must be 10 ms minimum following any write command that involves the E
2 memory.
9. 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 VDD = 5.5V.
