描述 Description

The CPC7582 is a monolithic solid-state switch in a 16-pin SOIC or DFN surface-mount package. It provides the necessary functions to replace two 2-Form-C electro-mechanical relays on traditional analog and integrated voice and data (IVD) line cards found in Central Office, Access, and PBX equipment. The device contains solid state switches for tip and ring line break, ringing injection/ringing return and test access. The CPC7582 requires only a +5V supply and offers break-before-make or make-before-break switch operation using simple logic-level input control.

The CPC7582xC logic states differ from the CPC7582xA/B. See “Functional Description” on page 12 for more information. The CPC7582xC also has a higher trigger and hold current for the protection SCR.
