Features
Description
• Switch Voltage up to 600V
The CPC7524 Quad High Voltage (HV) isolated
Analog Switch Array builds upon our high voltage
design and fabrication expertise for offline and
telecom applications. This monolithic solid state
device provides the switching functionality of four
normally open (1-Form-A) relays in one small
economical package.
• 110dB Switch-to-Switch Isolation at 5kHz
• Flexible Switch Configurations
• Smart Logic for Power-Up/Hot-Plug State Control
• 3.3V Operation with Very Low Power Consumption
• Switch Current Limiting and Thermal Shutdown
Protects Against Fault Conditions
• TTL Logic-Level Inputs
• Input Latch
Designed to provide flexible single-ended or
differential access to high voltage networks, the
CPC7524 high voltage array 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.
• Matched R
ON
• Clean, Bounce-Free Switching
• Monolithic IC Reliability
Applications
• Instrumentation
• Industrial Controls and Monitoring
• Worldwide AC Mains Monitor
• Automatic Test Equipment (ATE)
• Battery Monitoring and Charging
Independent switch current limiting and switch-pair
thermal shutdown features provide enhanced
protection for devices connected to high voltage
networks up to +600V.
