General Description
The 312decoders are a series of CMOS LSIs for remote control system applications. They are paired with 312series of encoders. For proper operation a pair of encoder/decoder with the same number of address and data format should be selected (refer to the encoder/decoder cross reference tables).

Features
• Operating voltage: 2.4V~12V
• Low power and high noise immunity CMOS technology
• Low standby current
• Capable of decoding 12 bits of information
• Pair with Holteks 312 series of encoders
• 8~12 address pins
• 0~4 data pins
• Trinary address setting
• Received data are checked two times
• Built-in oscillator needs only 5% resistor
