Overview
The PS8741-A is a high linearity optocoupler manufactured by CEL. It features a GaAs LED input and two photodiode outputs, providing linearized signal transfer with low temperature drift. The device operates within a temperature range of -40°C to +85°C and supports a reverse voltage of 3V with power dissipation of 180 mW. It is housed in a 16-SOP package and carries the -A suffix indicating lead-free compliance.
Feature Summary
- High linearity performance for accurate signal isolation
- Dual photodiode output configuration for enhanced stability
- Lead-free construction compliant with environmental standards
Applications
- Precision analog signal isolation
- Industrial control systems requiring high linearity
- Medical equipment signal processing
Procurement Notes
Verify the -A suffix confirms lead-free status as per manufacturer documentation. Ensure compatibility with 16-SOP footprint during integration. Confirm operating temperature range meets system requirements of -40°C to +85°C. Check datasheet for specific forward current limits before implementation.
Selection Notes
Select this component when high linearity and low temperature drift are critical. The dual photodiode design offers improved stability over single-channel alternatives. Verify that the 16-SOP package fits the available board space. Consider the 180 mW power dissipation limit for thermal management planning.
Part Context
This part belongs to CEL's high linearity optocoupler series. It utilizes GaAs LED technology for efficient light emission. The device is designed for applications requiring precise analog signal transmission across isolation barriers. The -A designation specifically denotes lead-free manufacturing.
Replacement Considerations
Check official cross-reference lists for compatible substitutes. Ensure any replacement maintains the 16-SOP package and dual photodiode architecture. Verify that alternative parts meet the same linearity and temperature specifications.
