3 Overview
CA-IS376x is a high-performance eight-channel digital isolator with precision
And low power loss. When isolating CMOS digital I/O,
CA-IS376x device can provide high electromagnetic immunity and low radiation. Owner
All versions have Schmidt trigger input, which can achieve high anti-noise performance.
The logic input and output buffers of each isolated channel are made of silicon dioxide
(SiO2) insulated barrier isolation. CA-IS3760 six channels are on the same side
Up; CA-IS3761 has five forward and one reverse channels, CA IS3762 has four forward and two reverse channels, and CA-IS3763 has
Three forward and three reverse channels. All equipment has failsafe mode
Type option. If the input side power supply is powered down or the signal is lost, for the suffix
For devices with L, the default output is low. For devices with suffix H
Standby, the default output is high.
CA-IS376x device has high insulation capacity, which helps prevent data bus
Or the noise and surge on other circuits enter the local grounding terminal, thus interfering
Or damage sensitive circuits. High CMTI capability is expected to ensure positive digital signal
To ensure transmission, CA-IS376x device adopts 16-pin narrow-body SOIC and 16-lead
Wide body SOIC package. All products have 3.75kVrms isolation
Rated value, wide-body packaged products support insulation and withstand voltage up to 5kVrms.
