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 ADM205, ADM206, ADM211, and ADM213 feature a low power shutdown mode which reduces power dissipation to less than 5 W, 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.

NOTES

1INTERNAL 400k PULL-UP RESISTOR ON EACH TTL/CMOS INPUT 2INTERNAL 5k PULL-DOWN RESISTOR ON EACH RS-232 INPUT

All members of the ADM2xx family, except the ADM209, include two internal charge pump voltage converters which allow operation from a single 5 V supply. These converters 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.

*This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operation sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADM205–ADM211/ADM213 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
