DS1620 Datasheet, PDF (12/13 Pages) Dallas Semiconductor – Digital Thermometer and Thermostat

NOTES:
1. All voltages are referenced to ground.
DS1620
2. Logic 1 voltages are specified at a source current of 1 mA.
3. Logic 0 voltages are specified at a sink current of 4 mA.
4. I_CC specified with DQ pin open and CLK pin at V_DD.
5. I_CC specified with V_CC at 5.0V and RST =GND.
6. Measured at V_IH = 2.0V or V_IL = 0.8V.
7. Measured at V_OH = 2.4V or V_OL = 0.4V.
8. Load capacitance = 50 pF.
9. t_CWH must be 10 ms minimum following any write command that involves the E² memory.
10. See typical curve for specification limits outside 0°C to 70°C range.
11. Thermometer error reflects temperature accuracy as tested during calibration.
12. Writing to the nonvolatile memory should only take place in the 0°C to 70°C temperature range.
13. Valid for design revisions D1 and above. The supply range for Rev. C2 and below is 4.5V < 5.5V.
