FEATURES 0.1 µF to 10 µF capacitors 120 kB/s data rate Two receivers active in shutdown (ADM213) On-board dc-to-dc converters ±9 V output swing with 5 V supply Low power (15 mW) Low power shutdown ≤ 5 µW ±30 V receiver input levels Latch-up free Plug-in upgrade for MAX205-211/213 APPLICATIONS Computers Peripherals Modems Printers Instruments 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, except the ADM209, 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. The ADM209 is designed to operate from 5 V and 12 V supplies. An internal +12 V to –12 V charge pump voltage converter generates the –12 V supply. Table 1.
