Product Summary

The ADM211EARS is a CMOS RS-232 Driver/Receiver. The ADM211EARS is intended for all EIA-232-E and V.28 communications interfaces, especially in applications where ±12 V is not available. The ADM211EARS features a low power shutdown mode which reduces power dissipation to less than 5 mW making them ideally suited for battery powered equipment. The ADM205 does not require any external components and is particularly useful in applications where printed circuit board space is critical. 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.
