Note 1: Devices are production tested at T A = +25°C. Limits over temperature are guaranteed by design.
Note 2: Operating below the UVLO causes all outputs to go low. The outputs are guaranteed to be in the correct state for V CC
down
to 1.2V.
Note 3: In order to guarantee an assertion, the minimum input pulse width must be greater than 2µs.
