ttl to cmos level translator circuit
Guys,
Do any of you remember how to shift TTL to CMOS with discretes?
Just need a few channels and don't want to burn a board.
Thank you,
MAKeller
Hey Desparate,
May I suggest you just glue some small gauge wires to a piece of cardboard and be done with it. Don't waste any more time looking for one. Ribbon cable is sold in bulk rolls of 100 ft. Unless of course you are interested in pre made cables.
Then I would try all the usual...
This type of AB switche (those that can switch UHF signals) are usually expensive.
What bandwidth should I desgin too? Are there any commerical units available under $25.00 US? Build for Buy?
Guys,
I'm not having a problem sweeping the
circuit, I just get the wrong output.
Does anyone have experience simulating
a wheatstone bridge circuit?
Thanks.
MAKeller
No offense taken, I have over 20 years
experience and still learn new things everyday.
I am measuring the output with .Probe (V+ - V-).
Do you know of any other way?
Any opinions or experiences are welcomed.
I am using Pspice 8.0 , 9.2.

Have tried the .PARM.
It sweeps the resistor as it should.
Unfortunely the output is positive only.
It should sweep output both negative and positive.
The wheatstone bridge is a differential circuit.
A potentometer is often put in a bridge to produce
a differential output.
I am trying to...
Gentlemen;
I'm trying to find out how to simulate a
potentometer and use it in a bridge circuit.
I think the best way to do this is with a
voltage controlled resistor.
Maybe I should use a couple of VSRC's in a subcircuit.
Have tried several ideas but the circuit doesn't output
my expected...
Re: load cell output?
Neelam,
The standard output of most load cells is 2mV/V.
Most use a wheat stone bridge and have a max
output of +/- 20mV @ 10V excitation.
The folowing companies sell load cells.

20hz filter circuits
Can anyone point me to a passive differential notch filter circuit?
Everything I have found on the net is for a single ended circuit.
I want to filter the telephone ringer on a digital answering machine.
Thanks Guys.
