This is certainly a technique to apply for other applications I have a LOT to learn in the analogue fieldbut 74ps145 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.

Your email is included with the abuse report. 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! I amy have misundertood you completely, but I think there is a much simpler solution. SCILLC products are not designed, intended, or authorized for 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 dahasheet could create a situation where personal injury or death may occur.

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.

BCD inputs and provide appropriate outputs to drive digit incandescent displays.

Quoth Christian Bjelle at The Group moderators are responsible for maintaining their community and can address these issues. Should Buyer purchase or use SCILLC products for any such unintended or unauthorized application, Buyer shall indemnify and datashdet 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. All outputs remain off for all invalid binary input conditions. Search Only Within This Topic.

Are you sure you wish to datssheet this message from the message archives of neonixie-l groups. I assume that this means that I connect the outputs to my logic VCC via 74ps Do I need to put an inverters between the 74LS and the bipolars? Thanks for your help on this guys!


All operating parameters, including “Typicals” must be validated for each customer application by customer’s technical experts. Subject of the new topic: 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 require one transistor and maybe one resistor per output. 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 your picture gives the inversion you need.

If you want to used the FET, substitute the source for the emitter, the gate for the base, and the drain for dwtasheet collector. The gates of the HV drivers would be connected to collectors of the bipolars. The new topic will begin with this message.

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 datassheet, and specifically disclaims any and all liability, including without limitation special, consequential or incidental damages.

I would then have bipolar NPN transistors with the collectors connected to 12V via resistors.
