Ground
Programmable Delay Terminal. Connect a capacitor from DELAY to GND to set the
ALARMD output delay time. To obtain a minimum delay, leave DELAY unconnected. See
Capacitance vs. ALARMD Output Delay in the Typical Operating Characteristics.
Delayed Fault Output. This output is the logic OR of ALARMA, ALARMB, and ALARMZ.
Place a capacitor from the DELAY pin to GND to set the delay (see Setting Delay Time). A
high logic level indicates a fault condition on at least one receiver input pair. A low level on
this pin indicates no fault condition is present.
Z Receiver Output. If V
be low. If Z or Z exceeds the receiver’s input common-mode voltage range, the ALARMZ
output will be high and OUTZ will be indeterminate.
Z Fault Output. When ALARMZ is high, OUTZ is indeterminate. Tables 1 and 2 show all the
possible states for which an alarm is set.
B Receiver Output. If V
be low. If B or B exceeds the input receiver’s common-mode voltage range, the ALARMB
output will be high and OUTB will be indeterminate.
B Fault Output. When ALARMB is high, OUTB is indeterminate. Tables 1 and 2 show all the
possible states for which an alarm is set.
A Receiver Output. If V
be low. If A or A exceeds the receiver’s input common-mode voltage range, the ALARMA
output will be high and OUTA will be indeterminate.
A Fault Output. When ALARMA is high, OUTA is indeterminate. Tables 1 and 2 show all the
possible states for which an alarm is set.
