Page 1

Revised Sept. 1998

PT2265 is a remote control encoder paired with PT2275 utilizing CMOS

Technology. Using a special coding technique, PT2265 increases noise immunity

to a very great extent and can perform one bit error check. It is housed in 14-pins,

DIP Package and has a maximum of eight (8) input channels. Its high

performance features make PT2265 a MUST in every fan and other electrical

home appliance remote control application.
