Description two channels in the same direction, the CA-IS3721 device has one forward and one reverse-direction channels, and the CA-IS3722 device has the channel configuration that is opposite to CA-IS3721. All devices have fail-safe mode option. If the input power or signal is lost, default output is low for devices with suffix L and high for devices with suffix H. CA-IS372x devices has high insulation capability to handle noise and surge on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. High CMTI ability promises the correct transmission of digital signal. The CA-IS372x devices are available in 8-pin SOIC and 8-pin wide body SOIC packages. And the CA-IS372x devices are also available in 8-pin wide body SOIC package. All products have 3.75kVrms isolation rating, and products in wide-body packages support insulation withstanding up to 5kVrms. Device Information PART NUMBER CA-IS3720, CA-IS3721, CA-IS3722 Copyright © 2019, Chipanalog Incorporated 上海川土微电子有限公司 BODY SIZE(NOM) SOIC8 (S) 4.90 mm × 3.90 mm SOIC8-WB(G) 5.85 mm ×7.50 mm Simplified Channel Structure Channel A side Schmitt Trigger The CA-IS372x devices are high-performance dual - channel digital isolators with precise timing characteristics and low power consumption. The CA-IS372x devices provide high electromagnetic immunity and low emissions, while isolating CMOS digital I/Os. All device versions have Schmitt trigger input for high noise immunity. Each isolation channel consists of a transmitter and a receiver separated by silicon dioxide (SiO2) insulation barrier. The CA-IS3720 device has PACKAGE Isolation Barrrier Channel B side Mixer VIN Driver VOUT Driver RX GNDA GNDB Channel A side and B side are separated by isolation capacitors. GNDA and GNDB are the isolated ground for signals and supplies of A side and B side respectively. PDF
