TRIMUX is basic component to build ternary hardware (including ternary computers). Positive voltage means +1 (P). Zero voltage means 0 (O). Negative voltage means -1 (N). Two power sources are required (+5 volts and -5 volts). This device consists of two independent multiplexers/demultiplexers and each of them may connect any of 3 inputs to 1 output based on control signal (connection may work in both directions - so it could be 3 outputs connected to 1 input). Switching frequency could be up to 1 MHz (see oscillograms).
(1) S1 - select input of the 1st ternary multiplexer
(2) N1 - connected to C1 if S1=N ("negative" or -5V)
(3) O1 - connected to C1 if S1=O ("zero" or 0V)
(4) P1 - connected to C1 if S1=P ("positive" or +5V)
(5) C1 - common signal of the 1st ternary multiplexer
(1) S2 - select input of the 2nd ternary multiplexer
(2) N2 - connected to C2 if S2=N ("negative" or -5V)
(3) O2 - connected to C2 if S2=O ("zero" or 0V)
(4) P2 - connected to C2 if S2=P ("positive" or +5V)
(5) C2 - common signal of the 2nd ternary multiplexer
(1) V-NEG - negative voltage (typically -5V)
(2) GND - ground wire
(3) V-POS - positive voltage (typically +5V)
Bill of Materials:
IC1,IC2: DG403 (DIP16)
C1-C4: 0.1uF (tantalum)
JP1,JP2:right-angle 5-pin headers
JP3: right-angle 3-pin header
By default you will get bare PCB only:
But you can choose options to have a KIT (PCB and set of components to solder TRIMUX) or even pre-assembled and fully tested board...

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
TERNARY RESEARCH CORPORATION was incorporated in New York State in June 2012 and relocated to Colorado in September 2017. Our goal is to give a chance to balanced ternary electronics. Also we are selling some peripherals for retro computers as ZX-Spectrum.
Usually we ship on the next business day, but sometimes it could be a week or so if board is not yet fully assembled and/or tested.
