Figure 1. GENERAL DESCRIPTION The ADM2xx family of line drivers/receivers is intended for all control. Two receivers of the ADM213 remain active during EIA-232-E and V.28 communications interfaces, especially in shutdown. This feature is useful for ring indicator monitoring. applications where 12 V is not available. The ADM206, All members of the ADM2xx family include two internal charge ADM211, and ADM213 feature a low power shutdown mode pump voltage converters that allow operation from a single 5 V that reduces power dissipation to less than 5 W, making them supply. These parts convert the 5 V input power to the 10 V ideally suited for battery-powered equipment. The ADM213 has required for RS-232 output levels. an active low shutdown and an active high receiver-enable Table 1.
