FUNCTION
Driver Input. A logic low on DI forces the noninverting output (Y) low and the inverting output (Z)
high. A logic high on DI forces the noninverting output (Y) high and the inverting output (Z) low.
Positive Supply. V
CC
= +3.3V 卤5%. Bypass V
CC
to GND with a 0.1碌F capacitor.
Driver Output Enable. Force DE high to enable driver. Pull DE low to disable the driver. Hot-swap
input, see the
Hot-Swap Capability
section.
