Features
Description
• Improved switch dV/dt immunity of 1500V/s
• Drop-in replacement for CPC7592
• TTL logic level inputs for 3.3V logic interfaces
• Smart logic for power up / hot plug state control
• Small 16-pin SOIC Package
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.
• Monolithic IC reliability
• Low matched R
• Eliminates the need for zero-cross switching
• Flexible switch timing to transition from ringing mode
to talk mode
ON
• Clean, bounce-free switching
• Tertiary protection consisting of integrated current
limiting, voltage clamping, and thermal shutdown for
SLIC protection
• 5V operation with power consumption <10mW
• Intelligent battery monitor
• Latched logic-level inputs, no external drive circuitry
required
The CPC7692BC has the same physical
characteristics as the CPC7692BA but has an
alternative logical set which provides different test
states.
