The MAX3097E/MAX3098E feature three high-speed RS-
485/RS-422 receivers with fault-detection circuitry and
fault-status outputs. The receivers’ inputs have fault
thresholds that detect when the part is not in a valid state.
The MAX3097E/MAX3098E indicate when a receiver
input is in an open-circuit condition, short-circuit condi-
tion, or outside the common-mode range. They also
generate a fault indication when the differential input
voltage goes below a preset threshold. See Ordering
Information or the Electrical Characteristics for thresh-
old values.
The fault circuitry includes a capacitor-programmable
delay to ensure that there are no erroneous fault condi-
tions even at slow edge rates. Each receiver is capable
of accepting data at rates up to 32Mbps.
