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-

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.
