The AD230, AD235, AD236 and AD241 feature a low power shutdown mode which reduces power dissipation to less than 5 j.L W making them ideally suited for battery powered equipment. The AD233 and AD235 do not require any external components and are particularly useful in applications where printed circuit board space is critical. SELECTION Part Number AD230 AD231 AD232 AD233 AD234 AD235 AD236 AD237 AD238 AD239 AD241 1\ll members of the AD230 family, except the AD231 and the AD239, include tWointernal charge pump voltage converters which allow operation from a single +5 V supply. These converters convert the + 5 V input power to the :t 10 V required for RS-232 output levels. The AD231 and AD239 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. TE In order to minimize the package count in all applications, a wide selection of driver/receiver combinations is available (see table below).
