74LS Datasheet PDF –

Medias this blog was made to help people to easily download or read PDF files. Search Only Within This Topic. 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. All operating parameters, including “Typicals” must be validated for each 74ls14 application by customer’s technical experts.

I would then have bipolar NPN transistors with the collectors connected to 12V via resistors. Are you sure you wish to delete this message from the message archives of neonixie-l groups. All outputs remain off for all invalid binary input conditions.


The gates of the HV drivers would be connected to collectors of the bipolars. The bases datasheeh the bipolars would be connected to the outputs of the 74LS via resistors.

So, for the meantime, it looks like my original plan stands, minus the base resistors thanks John!

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

Do I need datssheet put an inverters between the 74LS and the bipolars?

74LS (Hitachi) – Bcd-to-decimal Decoders / Drivers(with 15v Outputs)

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 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.

I dayasheet that this means that I connect the outputs to my logic VCC via 74ps This is certainly a technique to apply for other applications Datasheeet 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. If the 74LS will datazheet 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. 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 datasjeet, or for any other application in which the failure of the SCILLC product could create a situation where personal injury or death may occur.

You can skip the bipolar alltogether, and connect your pull-up directly to 12V. Subject of the new topic: The new topic will begin with this message.

Thanks for your help on this guys! If you want to used the FET, substitute the source for the emitter, the gate for the base, and the drain for the collector.
