For electronics hobbyists and engineers working on remote control systems, security projects, or wireless communication, here’s a handy bulk pack of 10 PT2272-L4 integrated circuits. These are decoder chips, often paired with PT2262 encoders, used to receive and decode signals from RF remote controls. They come in the common DIP-18 (Dual In-line Package, 18 pins) format, making them easy to use on breadboards or solder into PCBs. The ‘L4’ suffix indicates a specific output latch configuration. These are generic replacements for parts also labeled SC2272-L4. Whether you’re repairing an existing device or prototyping something new, having a few spares is always smart. Please note: this is for the ICs only; you’ll need to integrate them into your own circuit with the appropriate supporting components (resistors, capacitors, etc.) as per the datasheet.
