DG403: one chip with resistors

Here I use undocumented feature of DG403 when normally closed switch opened by voltage lower than required to close another (normally opened) switch. Variable resistor is used to move that “both-opened” window to ternary “0″ zone (up from -3.0V…-0.8V to cover 0V).

DG403-2

DG403: two chips - no more components

Second scheme is more “correct” (nothing from undocumented features were used).

P.S. Ternary selector may be used as ternary inverter when RP=-5V, RO=0V, RN=+5V. See more details on www.ternary.info

http://jeff.tk/wiki/Trinary

They started at November 2007, but they have built a few ternary modules already!

P.S. On January 2009 I found out that they changed port number for their web-site, so newlink to them is:

http://jeff.tk:81/wiki/Trinary

But unfortunately nothing was updated over there for a long time…

I hope it will have emulator soon. Then I will try to build REAL ternary computer…
