CPC75282
INTEGRATED CIRCUITS DIVISION
PRELIMINARY
Line Card Access Switch
Features
• Improved Switch dV/dt Immunity of 1500V/s
• Smart logic for power-up/hot-plug state control
• Small 44-pin TQFP Package
• Monolithic IC reliability
• Low, matched RON
• Eliminates the need for zero-cross switching
• Flexible switch timing to transition from ringing mode
to talk mode.
• Clean, bounce-free switching
• Tertiary protection consisting of integrated current
limiting, voltage clamping, and thermal shutdown for
SLIC protection
• 5V operation with very low power consumption
• Intelligent battery monitor
• Latched logic-level inputs, no external drive circuitry
required
Description
The CPC75282 Dual Line Card Access Switch
(LCAS), a member of IXYS Integrated Circuits
Division’s next generation Line Card Access Switch
family, is a monolithic solid state device that provides
the switching functionality of four 2-Form-C relays in a
single, small, economical package.
The CPC75282 Dual LCAS device is designed to
provide ringing and test access to the telephone loop
in Central Office, Digitally Added Main Line, Private
Branch Exchange, Digital Loop Carrier, and Hybrid
Fiber Coax/Fiber-In-The-Loop analog line card
applications. Test access switches provide access to
the telephone loop for line (drop) test or message
waiting in the PBX application.

1 P1, P2, and P3 data input values are directed to a given channel when the respective LATCHx logic signal is set to “0.”
OFFx is a per-channel control.
2 A “0” on OFFx resets the CPC75282, the device will remain in the All-Off state until OFFx is returned to “1” and the next LATCHx signal is
applied.
3 CFG is fixed at DGND; if CFG switches states when VDD is applied, the change will be recognized by a given channel after a LATCH low
transition is applied to that channel.
