I was planning to make a 8x8 LED matrix using 74HC595B1 ic but after looking at the datasheet Ive realized that with a maximum current output of 70ma that would not be happening.
being lazy and the fact i can do with a 5x5 as well, my question is if i design the matrix assuming only 1 row can be lit up at any given time ( 5 leds active at any time => individual pin current of 70/5 = 14ma) can this be done.
was planning to arrange the matrix in common cathode config with row and col selectors and using the appropriate current limiting resistors for the led.
worst comes to worst the leds would be a bit 'under-lit' .. am i correct ?
thanks for the help, ankit !
