PT2268 is a remote control encoder utilizing CMOS Technology specially designed  for use with the PT2128.  Using a special coding technique, PT2268 increases noise immunity to a very great extent.  It is housed in 16-Pins DIP Package and has a maximum of eight (8) input channels.  Its high performance features  make PT2268 a MUST in every fan  and other electrical home appliance remote control application.
PTC provides a new version of PT2268 which  can be identified by the "B" mark on the lower right hand corner of the IC's topcode (beside the date code).  Please refer to the diagram on the Order Information Section.  The difference between the old and new version is the external application circuit in the OSC1 and OSC2 pins.
