SGENERAL DESCRIPTION
OThe AD230 family of 5 V only, RS-232 line drivers/receivers
provides a variety of configurations to fit most communication
Lneeds, especially in applications where :t 12 V is not available.
EThe AD230, AD235, AD236 and AD241 feature a low power
shutdown mode which reduces power dissipation to less than
TE5 j.LW making them ideally suited for battery powered equip-
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 con-
verters 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.
