TMUX1511: channel2 simulation problem for PSPICE model?

Masatsune Isihara

Part Number: TMUX1511

Hi Experts,

we are having some problems with the PSPICE model (tmux1511.lib / scdm236.zip) of TMUX1511 - during the simulation, channel2 (D2/S2) does not work as expected (other three channels work).

An error appears in the simulation result only for channel2.

The same FAQ was confirmed:

e2e.ti.com/.../3351664

I tried replacing it with the provided PSPICE model(tmux1511.lib), but I got an error.
Do you know the details?

Hey Masatasune,

I took a look and it looks like there were a couple of typos in the lib file in the comparator for the control inputs leaving some of the nodes 'floating' or connected to nodes that do not technically exist. I've resolved the issues and am attaching the corrected PSPICE file below. This try using this file and let me know what you get!

2047.tmux1511.lib

Thanks!
