Do I need to put an inverters datashet the 74LS and the bipolars? 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. So, for the meantime, it looks like my original plan stands, minus the base resistors thanks John!

The new topic will begin with this message. Since the outputs of the LS are active low when selected, and the FET gate is active high, the transistor as dztasheet show it in your picture gives the inversion you need.

Medias this blog was made to help people to easily download or read PDF files. If the 74LS will sink enough dstasheet, I think you should be able to meet your needs with a cascode stage, and this will only require one transistor and maybe one resistor per output.

Should Buyer purchase or use SCILLC dafasheet for any such unintended or unauthorized application, Buyer shall indemnify and hold SCILLC and its officers, employees, subsidiaries, affiliates, and distributors harmless against all claims, costs, damages, and expenses, and reasonable attorney fees arising out of, directly or indirectly, any claim of personal injury or death associated with such unintended or unauthorized use, even if such claim alleges that SCILLC was negligent regarding the design or manufacture of the part.

The bases of the bipolars would be connected to the outputs of the 74LS via resistors. I would then have bipolar NPN transistors with the collectors connected to 12V via resistors. You can skip the bipolar alltogether, and connect your pull-up directly to 12V. SCILLC products are not designed, intended, or authorized 74os145 use as components in systems intended for surgical implant into the body, or other applications intended to support or sustain life, or for any other application in which the failure of the SCILLC product could create a situation where personal injury or death may occur.

Thanks for your help on this guys!

Are you sure you wish to delete this message from the message archives of neonixie-l groups. Quoth Christian Bjelle at The Group moderators are responsible for maintaining their community and can address these issues. 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.

The gates of the HV drivers would be connected to collectors of the bipolars.

I assume that this means that I connect the outputs to my logic VCC via 74ps Your email is included with datqsheet abuse report.

I amy have misundertood you completely, but I think there is a much simpler solution.

All operating parameters, including “Typicals” must be validated for each customer application by customer’s technical experts. BCD inputs and provide appropriate outputs to drive digit incandescent displays. All outputs remain off for all invalid binary input conditions. If you want 74lx145 used the FET, substitute the source for the emitter, the gate for the base, and the drain for the collector.
