HLT HT12E The 212 encoders are a series of CMOS LSIs for remote control applications. They are capable of encoding information consisting of N address bits and 12N data bits. Each address/data input can be set to one of two logical states. Main features - Operating voltage: 2.4 V ..12 V CMOS technology with low power consumption and high noise rejection - Low standby current - Decoding of 12 bit information possible - Binary address setting - Received codes are checked 3 times - Address/data number combination - Built-in oscillator requires only 5% resistance - Display of valid transmission - Simple interface with an RF or infrared transmission - Minimal external components The programmed addresses/data together with the header header bits are transmitted via an RF or infrared transmission medium on receipt of a trigger signal. The ability to select a TE trigger on the HT12E or a DATA trigger on the HT12A further increases the application flexibility of the 212 Series encoder. The HT12A also offers a 38kHz carrier for infrared systems. Applications - Burglar alarm systems - Smoke and fire detection systems - Garage door controls - Car door controls - Car alarm system - Security systems - Cordless telephones - Other remote control systems https://elecena.pl/product/23953306/ht12e-encoder-remote-control-2-4-12v-dip-18 2023-07-28 https://elecena.pl/product/23953306/ht12e-encoder-remote-control-2-4-12v-dip-18 2023-11-09 https://elecena.pl/product/23953306/ht12e-encoder-remote-control-2-4-12v-dip-18 2025-12-12 https://elecena.pl/product/23953306/ht12e-encoder-remote-control-2-4-12v-dip-18 2026-01-25
