Furthermore, MBI5170 uses the idea of Share-I-O™ technique to make MBI5170 backward patible with MBI5168 in both package and electrical characteristics and extend its functionality for run-time LED current gain control in LED display systems. MBI5170 contains an 8-bit Shift Register and an 8-bit Output Latch, which convert serial input data into parallel output format. At MBI5170 output stages, eight regulated current...
