Features
Description
• Low, Matched R
The CPC7514 Quad High Voltage (HV) isolated
Analog Switch Array builds upon our 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.
ON
• Switch Voltage up to 320V
• 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
Designed to provide flexible single-ended or
differential access to high voltage networks, the
CPC7514 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.
• Input Latch
• Clean, Bounce-Free Switching
• Monolithic IC Reliability
Applications
• Instrumentation
• Industrial Controls and Monitoring
• Automatic Test Equipment (ATE)
• Battery Monitoring and Charging
• Telephony
Independent switch current limiting and switch-pair
thermal shutdown features provide enhanced
protection for devices connected to high voltage
networks up to +320V.
• VoIP Gateways
• Central Office (CO) and Remote Terminal (RT)
• Digital Loop Carrier (DLC)
• Optical Terminals (ONT & ONU)
• PBX Systems
