Chipanalog CA-IS3988P Isolated Interface IC

Chipanalog CA-IS3988P

The CA-IS398x family of isolated octal digital inputs are optimized for industrial 24V digital input applications. All devices can be configured for Type 1, Type 2, or Type 3 inputs with a few external components and each channel can sink and source current. The isolation channels based on Chipanalog’s advanced capacitive isolation technology feature up to 2.5kVRMS isolation rating and ±300kV/μs typical CMTI (low-speed channels), provide high electromagnetic immunity, low propagation delay and low jitter.
