Part Number:SN74LVC1T45
Hi Logic Experts!
I have a customer who is using a SN74LVC1T45 to communicate from a micro to a TMP107 via 1-wire SMAART comms. They are able to use the SN745LVC1T45 to drive ~20 feet of cable to the first TMP107 but once they increase the length - they experience too much ringing and are unable to initialize the sensor (baud rate) and the system does not start collecting temp data.
The cable is 24AWG, 3 conductor.
Do you have any recommendations for terminations or a different device to help drive this cable with better impedance matching to increase distance for success SMAART communications?
Thanks!
