Motorola MC6525P NMOS Remote Control Receiver IC 12V PDIP-28 Wide
The Motorola MC6525P is a specialized NMOS integrated circuit designed as a remote control receiver and decoder for electronic control systems. It processes multiplexed input signals from compatible transmitters and converts them into binary-coded outputs that can be used to control different functions within electronic devices. This IC was originally designed to work with dedicated transmitters in remote control applications, enabling reliable program selection and command decoding.
The IC features an internal up/down counter, instruction decoder, and voltage comparator, allowing it to detect incoming control signals with good noise immunity and high input sensitivity. The MC6525P is typically used in systems requiring multiple programmable outputs, such as television remote control circuits, consumer electronics, and industrial control devices. Its DIP-28 package allows convenient through-hole mounting for PCB-based electronic designs.
