Notes:

Exceeding the absolute maximum rating may damage the device.

The device is not guaranteed to function outside its operating rating.

Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.

Specification for packaged product only.

HTH = VREF + VHYST.

DD operating range is 1.5V to 5.5V. Output is guaranteed to be de-asserted down to VDD = 1.2V.
