tions V
and V
must be the most positive of all V
’s
at all times including during power on and off ramping. As the
current taken through these V
’s is significantly less than
through the other V
’s this requirement can be easily met by
directly connecting all V
pins to a common point on the
circuit board but with the decoupling capacitors distributed to
minimise cross-talk caused by common mode currents. If low
value series resistors are to be included in the V
connec-
tions, with decoupling capacitors by the ACE9030 pins to
further reduce interference, the V
and V
pins should
not have such a resistor in order to guarantee that their
voltage is not slowed down at power-on. Power switches to
DOUT0 and DOUT1 are supplied from V
and are specified
for a total current of up to 40 mA so any resistor in the V
connection must be very low, around 1
, in order to avoid
excessive voltage drop; it is recommended that this supply
has no series resistor. These two methods are shown in circuit
diagrams, figures 4 and 5. In both circuits the main V
DD
must
also have good decoupling.
These are not the operating conditions, but are the
absolute limits which if exceeded even momentarily may
cause permanent damage. To ensure sustained correct op-
eration the device should be used within the limits given under
Electrical Characteristics.
To avoid any possibility of latch-up the substrate connec-
