Buffer logic gate

[JoeWawaw]

Could you use a buffer logic gate like a diode? it lets current go from input to output, but not the other way around?

Is a switch or relay a diode? The buffer you mention does not conduct current from input to output. The output current is a function of the chip, not the input current drive ability. In a diode, the two are related.

yes i agree, but if i were to put a voltage in the output of the buffer, would the input go high?

No, but you could zap the buffer.

@Joe,

Have you read about resistor-diode logic (sometimes just "diode logic")? Here is one link: http://hyperphysics.phy-astr.gsu.edu/hbase/electronic/diodgate.html Wikipedia also has a write up on it.
