Description
– Connect this pin to the ground of the system.
– –15 to –5 V
– The driver output: low level (VEE2 to VEE1 < 6.0 V)
(2/2)
Cautions 1. To prevent latch-up, turn on power to VDD1, VEE1, VEE2, VDD2, and logic input in this order. Turn off
power in the reverse order. These power up/down sequence must be observed also during
transition period.
2. Insert a capacitor of about 0.1 µF between each power line, as shown below, to secure noise margin
such as VIH and VIL.
