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)
