Remote Control Encoder
PT2268
DESCRIPTION
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. (see Oscillator Section)
