Power-Down Loc kout (
PDL
)
The power-down lockout pin
PDL
disables software
shutdown when low. When in shutdown, transitioning
PDL
from high to low wakes up the part with the output
set to the state prior to shutdown.
PDL
could also be
used to wake up the device asynchronously.
Daisy Chaining Devic es
Any number of MAX5251s can be daisy chained by
connecting the DOUT pin of one device to the DIN pin
of the following device in the chain (Figure 7).
Since the MAX5251’s DOUT pin has an internal active
pull-up, the DOUT sink/source capability determines
the time required to discharge/charge a capacitive
load. Refer to the serial-data-out V
OH
and V
OL
specifi-
cations in the Electrical Characteristics.
Figure 8 shows an alternate method of connecting sev-
eral MAX5251s. In this configuration, the data bus is
common to all devices; data is not shifted through a
daisy chain. More I/O lines are required in this configu-
ration because a dedicated chip-select input (
CS
) is
required for each IC.
