If this the device you are asking about: https://www.electro-tech-online.com/custompdfs/2013/04/snas544a.pdf Then no, 5VDC is not sufficient. 15VDC ought to work. It's worth noting that the TI device I cited above is obsolete.

M milanino New Member Apr 12, 2013 #4 I have found this device. this is the datasheet **broken link removed**
alec_t Well-Known Member Most Helpful Member Apr 12, 2013 #5 The datasheet says the supply voltage is typically 13-40V for the Tx and 12-37V for the Rx.
