MAX5152/MAX5153
Since the MAX5152/MAX5153’s DOUT has an internal
active pull-up, the DOUT sink/source capability deter-
mines the time required to discharge/charge a capaci-
tive load. Refer to the digital output V
OH
and V
OL
specifications in the
Electrical Characteristics
.
Figure 8 shows an alternative method of connecting
several MAX5152/MAX5153s. 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 configuration because a dedicated chip-select
input (CS) is required for each IC.
