CPC7581BA - Line Card Access Switch

Download the CPC7581BA datasheet PDF. This datasheet also covers the CPC7581 variant, as both devices belong to the same line card access switch family and are provided as variant models within a single manufacturer datasheet.

General Description

The CPC7581 is a monolithic solid-state four-pole switch in a 16-pin package.

It provides the necessary functions to replace a 2-Form-C electromechanical relay on traditional analog and integrated voice and data (IVD) line cards found in central office, access, and PBX equipment.

Key Features

  • Low, Matched RON.
  • Eliminates the Need for Zero-Cross Switching.
  • 5V Operation With Power Consumption < 10 mW.
  • Flexible Switch Timing for Transition from Ringing Mode to Idle/Talk Mode.
  • Clean, Bounce-Free Switching.
  • Tertiary Protection Consisting of Integrated Current Limiting, Thermal Shutdown for SLIC Protection.
  • Intelligent Battery Monitor.
  • Latched Logic-Level Inputs, No External Drive Circuitry Required.
  • SOIC Pac.
