Device Overview

Summary

The Le79R79 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
  • Through trapezoidal ringing
  • On-chip ring-trip detector
  • Low standby state power
  • Battery operation:
    • VBAT1: -40.5 to -75 V
    • VBAT2: -19 V to VBAT1
  • On-chip battery switching and feed selection
  • On-hook transmission
  • Two-wire impedance set by single external impedance
  • Programmable constant-current feed
  • Programmable Open Circuit voltage
  • Programmable loop-detect threshold
  • Current gain = 1000
  • Ground-key detector
  • Polarity reversal option available
  • Internal VEE regulator (no external -5 V power supply required)
