Passive-Input Digital Isolator - LOW CMOS Output

The NVE IL611F-1E is a single-channel passive-input digital isolator featuring a default LOW CMOS output, ideal for isolating logic signals in modern electronic systems. Manufactured with NVE’s patented IsoLoop® spintronic GMR technology, it provides up to 100Mbps data throughput with extremely low power dissipation and no carrier or clock required, reducing EMI susceptibility and noise. The passive input design allows direct interfacing with a broad range of logic levels using a simple current-limiting resistor, and the default LOW output provides a defined logic state for failsafe applications. Rated for up to approximately 1kVrms isolation with robust common-mode transient immunity, this isolator is suitable for reliable noise-immune digital signal coupling in compact surface-mount designs.

Key Features:

• Dual-channel passive-input isolator with default LOW CMOS outputs
