Relay Driver 3 Output. Output to drive an EMR, controlled by RD3I.
No Connect.
Relay Driver 2 Output. Output to drive an EMR, controlled by RD2I.
Relay Driver 1 Output. Output to drive an EMR, controlled by RD1I.
Ring Trip Sense Positive. Connect this pin to the ring relay and to the
ringer series through a high-value resistor.
Relay Driver 3 Input. This latched logic input sets the state of the relay driv-
er number 3. When using EMRs, the relay driver is controlled by this input
via a data bus or independent data line. When using an L758X solid-state
switch, the solid-state switch is controlled directly via the data bus or inde-
pendent data line and the relay driver is unused; in this case, tie this logic
input to ground.
Relay Driver 2 Input. This latched logic input sets the state of the relay driv-
er number 2. When using EMRs, the relay driver is controlled by this input
via a data bus or independent data line. When using an L758X solid-state
switch, the solid-state switch is controlled directly via the data bus or inde-
pendent data line and the relay driver is unused; in this case, tie this logic
input to ground.
Relay Driver 1 Input. This latched logic input sets the state of the relay driv-
er number 1. When using EMRs, the relay driver is controlled by this input
via a data bus or independent data line. When using an L758X solid-state
switch, the solid-state switch is controlled directly via the data bus or inde-
pendent data line and the relay driver is unused; in this case, tie this logic
input to ground.
NSTAT LED Driver. This output is equivalent to NSTAT, except this output
has sufficient drive capability to drive an LED. This LED driver output is an
open-collector output, so multiple outputs may be used to drive a single LED.
This output may be used as an alternative logic output to the latched NSTAT
output to indicate ring trip or loop supervision status. This output is valid re-
gardless of the state of EN.
Current-Limit Program Resistor. A resistor to DC
limit.
dc Output Voltage. This output is a voltage that is directly proportional to
the absolute value of the differential tip/ring current.
Ring Trip Sense Negative. Connect this pin to the ringing generator
through a high-value resistor.
