HT12D, 12-Bit Decoder IC, DIP-18, 2.4V-12V

The HT12D is a CMOS 12-bit decoder IC designed for remote control system applications. It decodes 8 address bits and 4 data bits received from a compatible encoder, such as the HT12E, transmitted via RF or infrared mediums. Upon receiving a valid transmission, indicated by the VT pin going high, the decoded data is presented on the output pins.Operating within a voltage range of 2.4V to 12V, the HT12D ensures reliable performance across various applications. Its low power consumption and high noise immunity make it suitable for battery-powered devices. The built-in oscillator simplifies design requirements, needing only an external resistor for frequency setting. The HT12D is commonly used in applications like burglar alarm systems, garage door controllers, car alarm systems, and other remote control systems. Its DIP-18 package facilitates easy integration into standard PCB designs.
