Component Features & Applications
- 4 independent transistor-output photocoupler channels in a single 16-pin SOP package saves 75% board space vs four discrete couplers
- 80 V VCEO per channel with 50 mA output and 2500 Vrms channel-to-input isolation for multi-signal isolation needs
- 100%–600% CTR per channel for reliable signal transfer across production variation in industrial automation
- Compact 10.3 × 5.3 mm SOP-16 Gull Wing package compatible with high-density SMD assembly and reflow soldering
- Low cross-coupling between channels enables independent isolated signal paths in mixed-signal and multi-voltage designs
- -55 °C to +100 °C operating range for industrial, telecom and automotive electronics requiring multi-channel isolation
