All operating parameters, including “Typicals” must be validated for each customer application by customer’s technical experts. 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. 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.
Search Only Within This Topic. I assume that this means that I connect the outputs to my logic VCC via 74ps Your email is included with the abuse report.
Do I need to put an inverters between the 74LS and the bipolars? The gates of the HV drivers would be connected to collectors of the bipolars. Since the outputs of the LS are active low when selected, and the FET gate is active high, the transistor 74lls145 74ls14 show it in your picture gives the inversion you 74lw145.

Should Buyer purchase or use SCILLC products 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.
Are you sure you wish to delete this message from the message archives of neonixie-l groups. Medias this blog was made to help people to easily download or read PDF files. You can skip the bipolar alltogether, and connect your pull-up directly to 12V.
So, for the meantime, it looks like my original plan stands, minus the base resistors thanks John! The bases of the bipolars would be connected to the outputs of the 74LS via resistors.

Quoth Christian Bjelle at The Group moderators are responsible for maintaining their community and can address these issues. If you want to used the FET, substitute the source for the emitter, the gate for the base, and the drain for the collector.

If the 74LS will sink enough current, I think you should be able to meet your needs with a cascode stage, and this will only dqtasheet one transistor and maybe one resistor datashheet output. Subject of the new topic: All outputs remain off for all invalid binary input conditions. Thanks for your help on this guys! I amy have misundertood you completely, but I think there is a much simpler solution. I would then have bipolar NPN transistors with the collectors connected to 12V via resistors.
