ELECTRICAL CHARACTERISTICS (V_CC = 5.0 V,PPV_VCCCC , = 12 V for typical values T_A = Low to High [Notes 8, 9, 10],
for min/max values T_A is the operating ambient temperature range that applies, unless otherwise noted.)

8. Maximum package power dissipation limits must be observed.
9. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
10. VID1, VID3, VID4 = logic 0, and VID0, VID2 = logic 1.
11. OUTEN is internally pulled low if VID0, 1, 2, 3, and 4 are floating.
12. Due to internal pullup resistors, there will be an additional 0.5 mA per pin if any of the VID0, 1, 2, 3, or 4 pins are pulled low.
