Remote Control Receiver IC
DESCRIPTION
The PT2249A_PT2250A Series are infra-red remote control receivers utilizing CMOS Technology.
Remote Control System can be constructed together with the PT2248 remote control encoder. The
PT2249A Series are packaged in 16 pins DIP (PT2249A version is also available in SOP package) and
are capable of controlling 10 functions while the PT2250A Series are packaged in 24 pins DIP and are
capable of controlling 18 functions. Several options, inverting/non-inverting IR signal input and/or
dependent/independent cyclic (toggle) outputs, are provided to fit different application needs.
FEATURES
