Valid for ambient operating temperature: TA = –30°C to +85°C; VCC = 2.7 V to 5.5 V (except where noted).

Guaranteed by design.

For VCC below VTH-, the output remains low down to VCC = 1 V. Below VCC = 1 V the voltage VIN must be less than

VOUT-OL (max.) to guarantee output low voltage less than 0.3 V.
