HT-12E, 12-Bit Encoder IC, DIP-18

The HT-12E is a CMOS 12-bit encoder IC, designed for remote control systems, security alarms, and wireless communication applications. It encodes 8 address bits and 4 data bits into a serial data output, which can be transmitted using an RF or infrared transmission medium. Operating between 2.4V and 12V, the HT-12E ensures reliable operation in low-power applications. Its built-in oscillator circuit simplifies frequency control, requiring only an external resistor for configuration. The device works seamlessly with the HT-12D decoder IC, making it a standard choice for wireless control applications. With its DIP-18 package, the HT-12E is ideal for use in remote control systems, alarm circuits, garage door controllers, and security applications.
