Hello,
I have a relay ( Quad package ). It requires 16mA current to operate. I need to toggle it from the PC with a optocoupler. My application needs eight of these relays and I can only use one optocoupler. So, I was thinking that optocoupler will drive all the input pins of the DM74LS244 at the same time and the DM74LS244's each output will drive the relay. Is it a good idea. All the relays will switch ON/OFF at the same time. The optocoupler can provide upto 14mA.
Relay :
Thanks John
