MULTIPROTOCOL SERIAL NETWORK INTERFACE IC

POWER SUPPLY CONSUMPTION
When external power supplies are available, the
switching regulator and charge pumps may be dis-
abled to save on component cost and current con-
sumption from the +5V supply.
The table below shows the typical currents the +5V,
+12V and -6V supplies require for each of the interface
modes.
The following two charts show how the IDD current
varies with temperature and voltage when only a sin-
gle 5V supply is used in the EIA-530 (V.11) mode.
This mode has the highest current consumption.
