CPC7593BCTR集成电路（IC）的电信规格书PDF中文资料

Description

The CPC7593 is a member of Clare’s next generation Line Card Access Switch (LCAS) family. This monolithic 10-pole line card access switch is available in a 20 or 28 pin SOIC or a 28 pin DFN package. It provides the necessary functions to replace three 2-Form-C electromechanical relays on analog line cards or combined voice and data line cards found in central office, access, and PBX equipment. The device contains solid state switches for tip and ring line break, ringing injection and test access.

Features

• TTL logic level inputs for 3.3V logic interfaces

• Smart logic for power up / hot plug state control

• Improved switch dv/dt immunity of 500 V/μs

• Small 20-pin or 28-pin SOIC or 28-pin DFN package

• DFN version provides 65 PCB area reduction over 4th generation EMRs

• Monolithic IC reliability

• Low, matched, RON

• Eliminates the need for zero-cross switching

• Flexible switch timing for transition from ringing mode to talk mode.

• Clean, bounce-free switching

• SLIC tertiary protection via integrated current limiting, voltage clamping and thermal shutdown
