Intersil HC-5560
The HC-5560 digital line transcoder provides encoding and decoding of pseudo ternary line code substitution schemes. The HC-5560 is fabricated in CMOS and operates from a single 5V supply. Unlike other industry standard transcoders, the HC-5560 provides four worldwide compatible mode selectable code substitution schemes, including HDB3 (High Density Bipolar 3), B6ZS, B8ZS (Bipolar with 6 or 8 Zero Substitution) and AMI (Alternate Mark Inversion).FEATURES
