These devices are also certified by VDE, TUV, CSA, and CQC. The ISO772x-Q1 devices provide high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier. The ISO7720-Q1 device has both channels in the same direction while the -Q1 device has both channels in the opposite direction. In the event of input power or signal loss, the default output is high for devices without suffix F and low for devices with suffix F. See the Device Functional Modes section for further details. Used in conjunction with isolated power supplies, these devices help prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. Through innovative chip design and layout techniques, the electromagnetic compatibility of the ISO772x-Q1 devices has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The ISO772x-Q1 family of devices is available in 16-pin SOIC wide-body (DW) and 8-pin SOIC narrow-body (D) packages. Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) ISO7720-Q1 ISO7721-Q1 SOIC (D) 4.90 mm × 3.91 mm SOIC (DW) 10.30 mm × 7.50 mm (1) For all available packages, see the orderable addendum at the end of the datasheet. Simplified Schematic VCCI and GNDI are supply and ground connections respectively for the input channels. VCCO and GNDO are supply and ground connections respectively for the output channels. |
