Description
The CNY74-2H is a high-reliability, dual-channel optocoupler IC featuring two independent isolation channels. Each channel consists of a gallium arsenide (GaAs) infrared-emitting diode optically coupled to a phototransistor. The device utilizes a sophisticated co-planar lead frame construction, ensuring a fixed and precise distance between the input and output elements to meet the highest safety and isolation requirements.
This 2-channel device is ideal for applications requiring robust galvanic separation, such as non-interacting switches and complex industrial control systems. With a low coupling capacitance and a stable Current Transfer Ratio (CTR) across a wide temperature range, the CNY74-2H ensures consistent performance and signal integrity in sensitive electronic designs.

Features
- Multi-Channel Design: 2 independent isolator channels in a single DIP-8 package.
- Safety: Co-planar construction ensures highest safety and isolation standards.
- Electrical Isolation: DC isolation test voltage (VIO) of 2.5 kV.
- Performance: Typical CTR of 100% with a low-temperature coefficient for consistent operation.
- Signal Integrity: Low coupling capacitance (typical 0.3 pF) reduces cross-talk and noise.
- Standardized: Complies with DIN 40 045 test class (25/100/21).
Benefits
- Provides two channels of galvanic isolation in one compact footprint.
