PT2272-M4 is a CMOS remote control decoder IC designed to work with the PT2262 encoder for wireless RF and infrared remote control applications. It decodes incoming encoded signals and provides four momentary data outputs, making it ideal for remote switching, security systems, garage door openers, home automation, and industrial control systems. The "M4" variant features 4 momentary output channels, where outputs remain active only while the corresponding transmitter button is pressed.
