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