Power-Down Lockout (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 asynchronously wake up the device.
Daisy Chaining Devices
Any number of MAX525s can be daisy chained by con-
necting the DOUT pin of one device to the DIN pin of
the following device in the chain (Figure 7).
Since the MAX525’s DOUT pin has an internal active
pullup, the DOUT sink/source capability determines the
time required to discharge/charge a capacitive load.
Refer to the serial-data-out VOH and VOL specifications
in the Electrical Characteristics.
Figure 8 shows an alternate method of connecting sev-
eral MAX525s. 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.
