HT680 - 3(18) Series of Encoders
The 318 encoders are a series of CMOS LSIs for remote control system applications.
They are capable of encoding 18 bits of information which consists of N address bits and 18-N data bits.
Each address/data input is externally trinary programmable if bonded out.
It is otherwise set floating internall
