Description
The CPC7692 is a member of IXYS IC Division’s
third-generation Line Card Access Switch (LCAS)
family. Available in a 16-pin SOIC package, this
monolithic 6-pole solid state switch provides the
necessary functions to replace two 2-Form-C
electromechanical relays used on traditional analog
line cards and on contemporary integrated voice and
data (IVD) line cards found in Central Office (CO),
Access, and PBX equipment. This device contains
solid state switches for tip and ring line break, ringing
injection/return, and test access, requires only a +5V
supply for operation and TTL logic-level inputs for
control. The CPC7692 provides stable start-up
conditioning during system power up, and for hot plug
insertion applications. Once active, the inputs respond
to traditional TTL logic levels, enabling the CPC7692
to be used with 3.3V logic devices.
The CPC7692BC has the same physical
characteristics as the CPC7692BA but has an
alternative logical set which provides different test
states.
