I need advice how to drive led display with 16x80 leds. My approach is to connect anodes to 4-16 decoder 74HC154, and cathodes to MBI5026GF constant current shift registers. Refresh display is 100Hz, and characteristics of leds I have are 3.0-3.2V, max. 18mA.
According to datasheet, MBI5026 is enable to deliver max. 90mA per pin.
I already simulate this in proteus and it works but I'm not sure am I going to have enough brightness in real life.
In attachment is schematics with HC595 instead of MBI5026.
Please, any suggestions are welcome.
Regards, Refik
