Overview
The CEL PS8741 is a dual-channel photovoltaic output optocoupler housed in a 16-SOP surface-mount package. It integrates a GaAs LED input with linearized photovoltaic outputs, providing high linearity for optical data applications. The device offers an isolation voltage of 1500Vrms and operates within a temperature range of -40°C to 85°C. Key electrical specifications include a maximum forward current of 50 mA and a nominal forward voltage of 1.1 V.
Feature Summary
- Dual-channel configuration with linearized photovoltaic outputs
- High linearity suitable for optical data transmission
- Robust 1500Vrms isolation barrier between input and output
Applications
- Optical data communication interfaces
- Telephony bandwidth signal isolation
- Linear analog signal transfer across isolation barriers
Procurement Notes
Verify component status as the PS8741 is listed as discontinued by major distributors. Confirm availability of alternative packages or suffixes if specific variants are required. Check for RoHS compliance details in official datasheets prior to integration into new designs.
Selection Notes
Select this component when high linearity and dual-channel isolation are required for analog or digital data transmission. Ensure the 16-SOP footprint matches the PCB layout. Consider the operating temperature range and isolation voltage requirements against system specifications before finalizing the design.
Part Context
Manufactured by CEL (California Eastern Laboratories), this part belongs to the NEPOC series of optocouplers. It was originally developed by NEC for high-performance isolation applications. The device represents a specialized solution for maintaining signal integrity while providing galvanic isolation in sensitive electronic circuits.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the component is discontinued, engineers must evaluate equivalent dual-channel linear optocouplers from other manufacturers that meet the 1500Vrms isolation and 16-SOP package requirements.
