HT12D RF Decoder IC

HT12D is a decoder IC for remote control applications, commonly in Radiofrequency (RF) wireless applications, and it is 2 series decoders. We can transmit 12 bits of parallel data serially by using HT12E and HT12D. HT12D is a simple Decoder IC that converts serial data to its input through RF to 12 bits parallel data in which there are 4 data bits and 8 address bits. These 8 bits addresses are security code for 4 bits data, which means we can provide 8 bits security code for 4 bits data and can use multiple receivers by using the same transmitter.

Features:

• Operating voltage: 2.4V~12V
• Low power and high noise immunity CMOS technology
• Low standby current
• Capable of decoding 12 bits of information
• Binary address setting
• Received codes are checked 3 times
• Address/Data number combination
• HT12D: 8 address bits and 4 data bits
• The built-in oscillator needs only a 5% resistor
• Valid transmission indicator
• Easy interface with an RF or an infrared transmission medium
• Minimal external components
• Pair with Holteks212 series of encoders
• 18-pin DIP

Applications:

• Burglar alarm system
• Smoke and fire alarm system
• Garage door controllers
• Car door controllers
• Car alarm system
• Security system
• Cordless telephones
• Other remote control systems
