Infrared Remote Control Receiver PT2249A / PT2250A Series
Description
The PT2249A / PT2250A Series are infra-red rem ote 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 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.
