CPC7512 Dual 1-Form-A Shunt-Isolated High-Voltage High-Frequency Analog Switch INTEGRATED CIRCUITS DIVISION Features • • • • • • • • • • • • • Description Up to ±320V Switch to Ground Potential Series Switches Open Contact Isolation up to +600V 60dB Off Isolation at 1MHz Thermal Shutdown Protects Against Fault Conditions Guaranteed Break-Before-Make Low, Matched RON Flexible Switch Configurations Smart Logic for Power-Up/Hot-Plug State Control 5V Operation with Very Low Power Consumption TTL Logic-Level Inputs Input Latch Clean, Bounce-Free Switching Monolithic IC Reliability The CPC7512 dual 1-Form-A high-voltage, high-frequency, shunt-isolated analog switch builds upon IXYS Integrated Circuits Division’s design and fabrication expertise for industrial applications. This monolithic solid state device provides the switching functionality of two normally open (1-Form-A) solid state relays for high frequency applications in one small economical package. Both switches incorporate shunt isolation by means of a T-switch compensation technique to minimize series capacitance through the open off-state switches for improved off-state isolation over frequency. Designed to provide flexible single-ended or differential access to high voltage networks, the CPC7512 is functionally configured as two independent logical switches. The self-biasing switches do not require external high-voltage supplies for proper operation. Applications • • • • • Multiplexed Ultrasonic Transducer Switching Battery Monitoring and Charging Automatic Test Equipment (ATE) Instrumentation Industrial Controls and Monitoring An integrated thermal shutdown feature provides not only enhanced protection for devices connected to high voltage networks up to +320V, but also an external signal to indicate the device is shut down.

Typical values are characteristic of the device at 25°C, and are the result of engineering evaluations. They are provided for informational purposes only and are not guaranteed by production testing. Unless otherwise noted the specifications cover the VDD operational range and the ambient operating temperature range TA = -40C to +85C. Testing is performed with the logic low input voltage VIL = 0VDC and the logic high input voltage VIH = VDD. Absolute maximum electrical ratings are at 25C. Absolute Maximum Ratings are stress ratings. Stresses in excess of these ratings can cause permanent damage to the device. Functional operation of the device at conditions beyond those indicated in the operational sections of this data sheet is not implied. 4 www.ixysic.com R01 CPC7512 INTEGRATED CIRCUITS DIVISION 1.5 Switch Electrical Specifications Parameter Off-State Leakage Current Test Conditions Symbol Minimum +85C, VSW = +330V On Resistance: SxA to SxB ISW - +0.3 +1 A +0.1 SWxA = SWxB = On, SWxC = Off ISW = ±10mA, ±40mA +25C RON +85C -40C On Resistance Matching: SxA to SxB Per On Resistance Test Conditions RON - 29 - - - 62 - 21 - - 0.1 1 - 60 - - 85 110 - 45 -   SWxA = SWxB = Off, SWxC = On ISW = ±10mA, ±40mA On Resistance: SWxC, SxC to SxCOM +25C RON +85C -40C Logic Input to Switch Output Isolation Unit +0.1 -40C, VSW = +310V High Frequency Dynamic Current Limit (t
