PT2560
PT2560 is an infrared remote control transmitter utilizing CMOS technology housed in a
20-pin DIP or SO 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 to replace M50560 with PT2560, you do not need to connect an
external capacitor to Pin No.3 (SEL Pin).
Pin assignments and application circuit of PT2560 are optimized for easy PCB layout
and cost saving advantage for remote control applications.

Note: Please take note that if you are replacing M50560 with PT2560, you do not need to connect an
external capacitor to PT2560's Pin No. 3 (SEL PIN). PT2560 SEL Pin must either be “floating’ or
connected to VDD.
