Hi there,
Trying to build a low voltage switching SPDT circuit.
Single input (High or Low),
If High then Red LED else Low Green LED.
Came across a TI datasheet, but I do not know this logic symbol.
Can someone explain me what this logic gate is please?
output = input
This compensates signal race times on the chip.
if not difficult can you explain what this means in a layman's term please?
Each signal has a propagation time through the silicon on the chip and this non-inverter ensures that both FETs are switched at the same time.
Propagation time of this logic gate is several seconds.
Leo..
If all you are doing is alternately turning on 2 LEDs then this circuit is way, way overkill. I don't think you can find an inverter and a buffer in a single package, either. The FETs would have to be logic level capable anyway, so at least one gate is redundant.
I don't think nanosecond race conditions are visible to the human eye. 
The replies you are getting cover a lot of territory because you didn't fully explain what you are doing.
Perhaps something like this could work.
I made a layman's term cheat sheet for the logic Gates in Computer Science. Hopefully this helps.
