Hi All
I have used a 74HCT14N for a circuit I have designed (not the best with electronics but learning) i was advised a 74HCT14N would do what i want but it does the opposite i have a photo interrupter that i want to turn an LED on when it is interrupted.
using the 74HCT14N when it recives a HIGH feed from the interrupter the LED is on when it receives a LOW feed (i block the signal) it turns off. is there a Cmos that operates the other way round ie turns on with a LOW and off with a HIGH?
thanks all
