DS1855 BLOCK DIAGRAM Figure 1
Up to eight DS1855s can be installed on a single 2-wire bus. Access to an individual device is achieved
by using a device address that is determined by the logic levels of address pins A0 through A2.
Additionally, the DS1855 will operate from 3V or 5V supplies. Three package options are available: 14-
pin TSSOP, 16-ball CSBGA, and flip-chip package.
