DS3695A/DS3696A Transmitting
DS3695A/DS3696A Receiving
X — Don’t care condition
Z — High impedance state
Fault — Improper line conditions causing excessive power dissipation in the driver, such as shorts or bus contention situations
* TS is an “open collector” output with an on-chip 10 k
** This is a fail safe condition
