POWER-UP SEQUENCE
Because of the ESD protection diodes that limit the voltage
compliance at the A, B, and W terminals (see Figure 45), it is
important to power on VDD before applying any voltage to the
A, B, and W terminals. Otherwise, the diodes are forward-
biased such that VDD is powered on unintentionally and can
affect other parts of the circuit. Similarly, VDD should be
powered down last. The ideal power-on sequence is in the
following order: GND, VDD, and VA/VB/VW. The order of
powering VA, VB, VW and the digital inputs is not important as
long as they are powered on after VDD.

LAYOUT AND POWER SUPPLY BIASING
It is always a good practice to use compact, minimum lead
length layout design. The leads to the input should be as direct
as possible with a minimum conductor length. Ground paths
should have low resistance and low inductance. It is also good
practice to bypass the power supplies with quality capacitors.
Apply low equivalent series resistance (ESR) 1 μF to 10 μF
tantalum or electrolytic capacitors at the supplies to minimize
any transient disturbance and to filter low frequency ripple.
