Holtek Semiconductor HA0064E

This application shows how to use the HT48R50A-1 to simulate the HT6032 3 12 decoder function to decode the 10 Address bits and 2 Data bits for the HT6010/HT6012. The corresponding width can decode skewed signals, the tolerance of which can be adjusted by MAXDURATION in the program.
