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 ADM223, ADM230L, ADM235L, ADM236L and ADM241L feature a low power shutdown mode that reduces power dissipation to less than 5 µW, making them ideally suited for battery powered equipment. Two receivers remain enabled during shutdown on the ADM223. The ADM233L and ADM235L do not require any external components and are particularly useful in applications where printed circuit board space is critical. All members of the ADM230L family, except the ADM231L and the ADM239L, include two internal charge pump voltage converters that 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 ADM231L and ADM239L are 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. The ADM2xxL is an enhanced upgrade for the AD2xx family featuring lower power consumption, faster slew rate and operation with smaller (1 µF) capacitors.
