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.
