Isolated Analog Switch Array serves high-voltage applications.April 15, 2011 -
Offered in 20-pin SOIC package, CPC7514Z has 4 independently controlled, 320 V, bidirectional, NO relays actuated by latched TTL logic-level control signals. Monolithic silicon IC, featuring high-voltage DMOS structures as well as low-voltage CMOS circuitry, is biased by 3.3 V power supply and has switch output to logic input isolation of ±320 V. IC provides flexible single-ended or differential access to high-voltage networks and may also be configured as 2 sets of matched pair switches.

Clare Introduces Industry's First Monolithic High-Voltage Isolated Analog Switch Array
320V Bidirectional Switch Capability for High-Voltage Interface Applications Powered by a 3.3V Digital Supply
Beverly, MA - Clare, Inc., a subsidiary of IXYS Corporation (NASDAQ: IXYS), today announced the availability of the CPC7514Z Quad High- Voltage Isolated Analog Switch Array for use in industrial controls, instrumentation, automatic test equipment and telecom applications. The CPC7514Z ICs feature four independently controlled, 320V bidirectional normally open (1-Form-A) relays actuated by latched TTL logic-level control signals. The monolithic silicon, which features high voltage DMOS structures and low voltage CMOS circuitry, is biased by a 3.3V power supply eliminating the requirement for external high-voltage supplies for proper operation. Switch-output to logic-input isolation is +/- 320V.
Designed to provide flexible single-ended or differential access to high voltage networks, the CPC7514Z may also be configured as two sets of matched pair- switches for improved differential performance. The switch pairs have an on-resistance matching specification of 0.8 Ohm maximum over the industrial temperature range of -40 to +85 degrees Celsius.
The individual switches have active current-limiting protection for fault events which limits the low frequency currents to 200mA. Under serious high-power fault conditions, which may raise the IC junction temperature, a thermal shutdown protection feature is provided. Between the initial current-limit and the thermal-shutdown events, a secondary, low-level, current-limit mode is provided to limit the power dissipation of the switches. Protection continues until the fault is removed. These features offer robust circuit protection in adverse application environments.
These switch arrays are fabricated using Clare's bonded-wafer, silicon-on-insulator, BCDMOS process with trench isolation. Clare's BCDMOS IC process has been used for many years in central office telecom equipment requiring long operational life (17+ years). Clare's integrated Line Card Access Switch (LCAS) ICs which are fabricated in the same BCDMOS process have replaced many electromechanical 2-Form-C relays, enabling higher density line card designs.
In addition to telecom, the CPC7514Z may be used as four normally open relays in automatic test equipment (ATE), industrial controls, battery monitoring/charging equipment and instrumentation applications. The device may also interface directly with 110Vrms AC in switch applications replacing banks of electromechanical relays (EMRs) and driver circuitry for enhanced system integration. Many applications will benefit from the elimination of a costly DC/DC converter block that is generally incorporated to bias the external EMRs.
Pricing and Availability
The CPC7514Z is available in a 20-pin SOIC package, and is available in production quantities. Pricing for OEM quantities of 10KU is $3.99.
