Hi
I need some help with my project:
I am using TTL logic to drive common cathode dual displays. On some inputs to the display I have nearly 5v (approx 4.8v) but it's not enough to light the display. There is not a problem with the individual segments as they light when they're connected to the 5v rail via a resistor. I need a way to boost the output from the logic to 5v so it will light the display.
Any ideas welcome
please reply a.s.a.p as the deadline is soon!!!
cheers
