Infrared Remote Control Transmitter
PT2560
Description

PT2560 is an infrared remote control transmitter utilizing CMOS technology housed in a 20-pin DIP or
SOP package. A 4 x 8 key matrix and extension bit inputs allow the transmission of up to 256
instructions. The transmission code consists of 16 bits code (8 bits custom code and 8 bits data code)
and a leader code. PT2560 is functionally compatible with M50560. However, there is a slight
difference in their application circuits. If you are replacing M50560 with PT2560, please take note that
PT2560 Pin No. 3 is an NC Pin (No Connection) and therefore, as the pin name implies, this pin must
not be connected to any external electrical component (i.e. capacitor as in M50560).

Pin assignments and application circuit of PT2560 are optimized for easy PCB layout and cost
saving advantage for remote control applications.
