Analog Ground - To be connected to zero potential. Serves as a reference for the transmit output and receive input
terminals.
Positive Voltage Source - most positive supply.
Capacitor #C
operation of the loop current limiting function.
Function Address #1 - A TTL and CMOS compatible input used with F0 function address line to externally select logic
functions. The three selectable functions are mutually exclusive. See Truth Table. F1 should be toggled high after power
is applied.
Function Address #0 - A TTL and CMOS compatible input used with F1 function address line to externally select logic
functions. The three selectable functions are mutually exclusive. See Truth Table.
Ring Synchronization Input - A TTL - compatible clock input. The clock is arranged such that a positive pulse (50Ps -
500Ps) occurs on the zero crossing of the ring voltage source, as it appears at the RFS terminal. For Tip side injected
systems, the RS pulse should occur on the negative going zero crossing and for Ring injected systems, on the positive
going zero crossing. This ensures that the ring delay activates and deactivates when the instantaneous ring voltage is
near zero. If synchronization is not required, the pin should be tied to 5.
Switch Hook Detection - An active low LS, TTL-compatible logic output. A line supervisory output.
Ground Key Detection - An active low LS, TTL-compatible logic output. A line supervisory output.
A TTL logic input. A low on this pin will set a latch and keep the SLIC in a power down mode until the proper F1, F0
state is set and will keep ALM low. See Truth Table.
An LS TTL-compatible active low output which responds to the thermal detector circuit when a safe operating die
temperature has been exceeded. When TST is forced low by an external control signal, ALM is latched low until the
proper F1, F0 state and TST input is brought high. The ALM can be tied directly to the TST pin to power down the part
when a thermal fault is detected and then reset with F0, F1. See Truth Table. It is possible to ignore transient thermal
overload conditions in the SLIC by delaying the response to the TST pin from the ALM. Care must be exercised in
attempting this as continued thermal overstress may reduced component life.
Loop Current Limit - Voltage on this pin sets the short loop current limiting conditions using a resistive voltage divider.
The analog output of the spare operational amplifier.
The inverting analog input of the spare operational amplifier.
