Cool re. working!

How did the invisible organic coating, as opposed to more traditional tin coating, behave with soldering? Any issues?

I didn't know yet. I thought that it's just copper, so I finished this one manually using liquid rosin flux and my soldering iron...

1st board was assembled and tested - it's working :)

When V-NEG=-4.4V and V-POS=+4.4V TRIMUX has thresholds at -3.1V and +1.6V (around second threshold there is a short range of voltage when one switch is already opened, but second is not yet closed). Later I will test it on voltages +5V and -5V.


When V-NEG=-5.0V and V-POS=+5.0V TRIMUX has thresholds at -3.4V and +1.9V

P.S. According to the logo, manufacturer of these DG403s is "Siliconix Inc" (current owner of this brand is Vishay):

See their datasheet here

One possible application of this device - Ternary Half-Adder:

Full adder will require 7 TRIMUX devices

Speed test of TRIMUX connected as inverter (without resistors):

It looks like speed limit for TRIMUX is 1 MHz

If somebody wants to test it I can send 1 PCB for free (actually for feedback)
