CMOS ED5026/5027 is a type of large-scale digital encoding / decoding ASIC. ED5026 is 8-bit code transmitter (can be extended to 12 bits), and ED5027 is 12-bit information receiving address.They constitute the infrared remote control system. They may also constitutethe radio, ultrasonic remote control mode. Rain gear made extensive application. Similar models are: VK5026/5027，YYH26/YYH27/YHH28 etc. The following figure shows infrared remote control transmitter / receiver application circuit (remote control four kinds of electrical appliances) composed of ED5026/5027:
