NOTES:
1. Temperature conversion will work with ±2°C accuracy down to VDD=2.7V.
2. I/O line in “hi-Z” state and II/O=0. Resistance specified from I/O to ground.
3. See typical curve for specification limits outside 0°C to 70°C range. Thermometer error reflects
sensor accuracy as tested during calibration.
4. Specified with DQ=VDD.
5. The bus should not remain idle for more than 20 ms between bits or between a bit and a reset.
