74LS Datasheet PDF –

Thanks for your help on this guys! Since the outputs of the LS are active low when selected, and the FET gate is active high, the transistor as 74ls14 show it in 74lss145 picture gives the inversion you need.

This is certainly a technique to apply for other applications I have a LOT to learn in the analogue fieldbut I think that we would have the same issue that John pointed out — the control signals are inverted and still need to be flipped before they get to the output device.

BCD inputs and provide appropriate outputs to drive digit incandescent displays. 74l145 outputs remain off for all invalid binary input conditions. So, for the meantime, it looks like my original plan stands, minus the base resistors thanks John!

That makes my life much easier, although I will have to check on the manufacturer of the devices that I have to make sure that they have the higher voltage tolerance.

Dtaasheet operating parameters, including “Typicals” must be validated for each customer application by customer’s technical experts. I assume that this means that I connect the outputs to my logic VCC via 74ps The bases of the bipolars would be connected to the outputs of the 74LS via resistors.

I amy have misundertood you completely, but I think there is a much simpler solution. You can skip the bipolar alltogether, and connect your pull-up directly to 12V.

Quoth Christian Bjelle at The Group moderators are responsible for maintaining their community and can address these issues. Do I need to put an inverters between the 74LS and the bipolars? SCILLC makes no warranty, representation or guarantee regarding the suitability of its products for any particular purpose, nor does SCILLC assume any liability arising out of the application or use of any product or circuit, and specifically disclaims any and all liability, including without limitation special, consequential or incidental damages.

Subject of the new topic: The gates of the HV drivers would be connected to collectors of the bipolars. If the 74LS will sink enough current, I think you should be able to meet dtasheet needs with a cascode stage, and this will only require one transistor and maybe one resistor per output.

If you want to used the FET, substitute the source for the emitter, the gate for the base, and the drain for the collector. I would then have bipolar NPN transistors with the collectors connected to 12V via resistors.
