GENERAL DESCRIPTION
The ADM2xx family of line drivers/receivers is intended for all
EIA-232-E and V.28 communications interfaces, especially in
applications where ±12 V is not available. The ADM206,
ADM211, and ADM213 feature a low power shutdown mode
that reduces power dissipation to less than 5 μW, making them
ideally suited for battery-powered equipment. The ADM213 has
an active low shutdown and an active high receiver-enable

control. Two receivers of the ADM213 remain active during
shutdown. This feature is useful for ring indicator monitoring.
All members of the ADM2xx family include two internal charge
pump voltage converters that allow operation from a single 5 V
supply. These parts convert the 5 V input power to the ±10 V
required for RS-232 output levels.
