CNY74-4H 4-Channel Optocoupler IC – Phototransistor Output DIP-16

Description

The CNY74-4H is a high-reliability, multi-channel optocoupler IC featuring four 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 4-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 CNY74-4H ensures consistent performance and signal integrity in sensitive electronic designs.
