    Hi Art, The LS09 has a limit of 5.5V at the output. TTL outputs typically only can reach about 2.4V, so a pull-up resistor to 5V is a very significant improvement. The SN74LS07 has the highest voltage outputs in all of the logic portfolio - they support…

    Only logic gates with OE are designed to be able to disable the outputs when the supply voltage is too low. The SN74LS07 has three diode drops for both the output transistor and the shunt transistor. It might work, but this is not something that is…
