#63880 - RE: pca 9555 Responding to: ???'s previous message |
How about using 3 cascaded 74HC595 shift registers - only three pins needed. They can drive low-current LEDs directly, and you could add a ULN2803A for the relays. You could also use the Allegro chip the combines the 595 and 2803 in one chip - can't remember the name.
