Bipolar-DI CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTES: 1. Absolute maximum ratings are limiting values, applied individually, beyond which the serviceability of the circuit may be impaired. Functional operability under any of these conditions is not necessarily implied. 2. θJA is measured with the component mounted on an evaluation PC board in free air.

Functions with the Ring terminal to receive voice signals from the telephone and for loop monitoring purposes. An analog input connected to the RING (more negative) side of the subscriber loop through a sense resistor (RS) and a ring relay contact. Functions with the Tip terminal to receive voice signals from the telephone and for loop monitoring purposes. Senses ring side of loop for ground key and ring trip detection. During ringing, the ring signal is inserted into the line at this node and RF is isolated from RFS via a relay. Positive Voltage Source - Most positive supply. VB+ is typically. Capacitor #1 - An external capacitor to be connected between this terminal and analog ground. Required for proper operation of the loop current limiting function, and for filtering VB-. Typical value is 0.3µF, 30V. Digital Ground - To be connected to zero potential and serves as a reference for all digital inputs and outputs on the SLIC microcircuit. Ring Synchronization Input - A TTL - compatible clock input. The clock should be arranged such that a positive pulse transition 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
