74LS Datasheet PDF ( Pinout ) – 1-OF DECODER/DRIVER OPEN-COLLECTOR

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

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 datasheef the devices that I have to make sure datasneet they have the higher voltage tolerance.

The new topic will begin with this message.

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 product could create a situation where personal injury or death may occur. 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 74lx145 — the control signals are inverted and datasheeh need to be flipped before they get to the output device.

Your email is included with the abuse report. Thanks for your help on this guys! Subject of daatsheet new topic: You can skip the bipolar alltogether, and connect your pull-up directly to 12V.

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

The bases of the bipolars would be connected to the outputs of the 74LS via resistors. If you want to used the FET, substitute the source for the emitter, the gate for the base, and the drain for the collector.

Since the outputs of the LS are active low when selected, and the FET gate 7l4s145 active high, the transistor as 74ls14 show it in your picture gives catasheet inversion you need.

BCD inputs and provide appropriate outputs to drive digit incandescent displays. The gates of the HV drivers would be connected to collectors of the bipolars. Do I need to put an inverters between the 74LS and the bipolars? All operating parameters, including “Typicals” datadheet be validated for each customer application by customer’s technical experts.
