CPC7514 (Rev 6) Data Sheet

The CPC7514 Quad High Voltage (HV) isolated Analog Switch Array builds upon IXYS Integrated Circuits Division's Line Card Access Switch (LCAS) design and fabrication expertise for telecom and non-telecom applications. This monolithic solid state device provides the switching functionality of four normally open (1-Form-A) relays in one small economical package.

Designed to provide flexible single-ended or differential access to high voltage networks, the CPC7514 High Voltage Array (HVA) is configured as
two sets of matched, paired switches for improved differential performance. Additionally, sensitive differential applications will benefit from the matched pairs’ excellent pair-to-pair isolation. The self-biasing switches do not require external high-voltage supplies for proper operation.

Independent switch current limiting and switch-pair thermal shutdown features provide enhanced protection for devices connected to high voltage networks up to ±320V.
