Notes:
1. Initiating a RH measurement will also automatically initiate a temperature measurement. The total conversion time will
be t_CONV(RH) + t_CONV(T).
2. No conversion or I²C transaction in progress. Typical values measured at 25 °C.
3. Occurs once during powerup. Duration is <5 msec.
4. Occurs during I²C commands for Reset, Read/Write User Registers, Read EID, and Read Firmware Version. Duration is
<100 µs when I²C clock speed is >100 kHz (>200 kHz for 2-byte commands).
5. IDD after a user register write. Initiating any other subsequent I²C transaction on the same bus (such as the user
register read, starting an RH measurement, or traffic directed at other I²C devices) will transition the device to standby
mode.
6. Additional current consumption when HTRE bit enabled. See section “5.5. Heater” for more information

Notes:
1. All values are referenced to V_IL and/or V_IH.
2. Depending on the conversion command, the TH06 may hold the master during the conversion (clock stretch). At
above 100 kHz SCL, the TH06 may also hold the master briefly for user register and device ID transactions. At the
highest I²C speed of 400 kHz the stretching will be <10 µs.
3. Pulses up to and including 50 ns will be suppressed.
