Device Overview

Summary

The Le79R70 is a bipolar monolithic SLIC device that support integrated (on-chip) ringing, pin-for-pin compatibility and flexibility for varying loop lengths. With the Ringing SLIC, you can achieve significant system-level cost reductions while designing innovative linecard solutions.

Additional Features
  • Ideal for ISDN-TA and set top applications
  • On-chip ringing with on-chip ring-trip detector
  • Low Standby state power
  • Battery operation:
    • VBAT1: -40 V to -67 V
    • VBAT2: -19 V to VBAT1
  • On-chip battery switching and feed selection
  • On-hook transmission
  • Polarity reversal option
  • Programmable constant-current feed
  • Programmable open circuit voltage
  • Programmable loop-detect threshold
  • Two-wire impedance set by single component
  • Ground-key detector
  • Tip Open state for ground-start lines
  • Internal VEE regulator (no external -5 V power supply required)
  • Two on-chip relay drivers and snubber circuits
