Pin Descriptions 24 PIN DIP/SOIC SYMBOL DESCRIPTION 1 TIP An analog input connected to the TIP (more positive) side of the subscriber loop through a sense resistor (RS) and a ring relay contact. Functions with the Ring terminal to receive voice signals from the telephone and for loop monitoring purposes. 2 RING 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. 3 RFS 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. 4 VB+ 5 C1 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. 6 DG Digital Ground - To be connected to zero potential and serves as a reference for all digital inputs and outputs on the SLIC microcircuit. 7 RS 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 the ring relay activates and deactivates when the instantaneous ring voltage is near zero. If synchronization is not required, the pin should be tied to 5V. 8 RD Relay Driver - A low active open collector logic output. When enabled, the external ring relay is energized. 9 TF Tip Feed - A low impedance analog output connected to the TIP terminal through a sense resistor (RS). Functions with the RF terminal to provide loop current, feed voice signals to the telephone set, and sink longitudinal current. 10 RF Ring Feed - A low impedance analog output connected to the RING terminal through a sense resistor (RS). Functions with the TF terminal to provide loop current, feed voice signals to the telephone set, and sink longitudinal current. 11 VB- Negative Voltage Source - Most negative supply. VB- is typically -48V with an operational range of -42V to -58V. Frequently referred to as “battery”. 12 BG Battery Ground - To be connected to zero potential. All loop current and some quiescent current flows into this ground terminal. 13 SHD 14 NC Positive Voltage Source - Most positive supply. VB+ is typically. Switch Hook Detection - A low active LS TTL - compatible logic output. This output is enabled for loop currents exceeding the switch hook threshold. Used during production test. Leave disconnected. 4 FN6101.0 HC5503PRI Pin Descriptions (Continued) 24 PIN DIP/SOIC SYMBOL DESCRIPTION 15 PD Power Denial - A low active TTL - Compatible logic input. When enabled, the ring feed voltage collapses to the tip feed voltage (~4V). The DC feed is disabled, but the AC transmission is maintained. The switch hook detect (SHD) is not necessarily valid, and the relay driver (RD) output is disabled. 16 RC Ring Command - A low active TTL - Compatible logic input. When enabled, the relay driver (RD) output goes low on the next high level of the ring sync (RS) input, as long as the SLIC is not in the power denial state (PD = 0) or the subscriber is not already off- hook (SHD = 0). 17 NC 18 OUT Leave disconnected. 19 -IN The inverting analog input of the spare operational amplifier. 20 +IN The non-inverting analog input of the spare operational amplifier. 21 RX Receive Input, Four Wire Side - A high impedance analog input which is internally biased. Capacitive coupling to this input is required. AC signals appearing at this input differentially drive the Tip feed and Ring feed terminals. 22 C2 Capacitor #2 - An external capacitor to be connected between this terminal and analog ground. This capacitor is required for the proper operation of ring trip detection. Recommended value 0.82µF ±10% 10V non-polarized. 23 AG Analog Ground - To be connected to zero potential and serves as a reference for the transmit output (TX) and receive input (RX) terminals. 24 TX Transmit Output, Four Wire Side - A low impedance analog output proportional to the loop current. Transhybrid balancing must be performed beyond this output to completely implement two to four wire conversion. This output is unbalanced and referenced to analog ground. Since the DC level of this output varies with loop current, capacitive coupling to the next stage is essential. NC No internal connection. The analog output of the spare operational amplifier. NOTE: All grounds (AG, BG, and DG) must be applied before VB+ or VB-. Failure to do so may result in premature failure of the part. If a user wishes to run separate grounds off a line card, the AG must be applied first.
