Source: InternetPublisher:国民男神经 Keywords: Infrared remote control Updated: 2024/09/05
ED5026/5027 is a CMOS type large-scale digital encoding/decoding ASIC. ED5026 is an 8-bit encoding transmitter (expandable to 12 bits), and ED5027 is a 12-bit information receiving address. In addition to forming an infrared remote control system, they can also form radio frequency, ultrasonic and other remote control methods, and are widely used in rain gear. Similar models include: VK5026/5027, YYH26/YYH27/YHH28, etc.
