Notes

18.

Rise and Fall Slew Rates A measured across a 5.0

Ω resistive load at high side output = 0.5V to VPWR -3.5V. These parameters are

guaranteed by process monitoring.

19.

Rise and Fall Slew Rates B measured across a 5.0

Ω resistive load at high side output = VPWR -3.5V to VPWR -0.5V. These parameters

are guaranteed by process monitoring.

20.

Turn-ON delay time measured from rising edge of IN[0:1] signal that would turn the output ON to VHS[0:1] = 0.5V with RL = 5.0Ω resistive

load.

21.

Turn-OFF delay time measured from falling edge that would turn the output OFF to VHS[0:1] = VPWR -0.5V with RL = 5.0Ω resistive load.
