Hello All,
I am looking for a particular part for a project, but can't seem to find quite what I'm looking for. I was hoping someone might know of a suitable part.
I am looking for a single, non-inverting Schmitt trigger chip, similar to the 74LVC1G17 which will work on 12 volts. Several mfr's make versions of it for 5 volts. (Link is to the datasheet of the NXP version.) I have found several hex (6-per-chip) versions such as the CD40106BC which work with 12 volts, just can't find a single version. I am looking for a single 12v version a) because I only need one per location, and more importantly b) need the smallest possible part.
FYI: This is to clean up and buffer the signal going to 12volt WS2811 pixels where the pixels are a long distance from the controller. They are finicky about the data signal and it is prone to noise on long runs. The typical solution is to install "ghost" pixels along the way, but I was looking to put a tiny chip on a 1/4" by 1/2" board which could be installed inline and covered with shrinkable tubing. Pixels are too big because the wire needs to get pulled thru conduit.
Current plan is to just use SOP ws2811 chips with no LEDs, but Schmitt triggers would be even better if I can find them. The Schmitt will do a better job at cleaning up the signal. Unfortunately, the WS2811's do not include a Schmitt on the input. If they did, they wouldn't be so cantankerous about the signal.
Can anyone suggest a part number?
