Remote Control Encoder

PT2268

PT2268 v 2.4

Page 1

Revised March 1999

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.
