These • Integrated Noise Filter on the Inputs devices have four isolated channels comprised of • Default Output 'High' and 'Low' Options logic input and output buffers separated by a silicon dioxide (SiO2) insulation barrier. ISO7340 has four • Low Power Consumption, Typical ICC per Channel channels in forward direction, ISO7341 has three at 1 Mbps: forward and one reverse-direction channels; and – ISO7340: 0.9 mA (5 V Supplies), ISO7342 has two forward and two reverse-direction 0.7 mA (3.3 V Supplies) channels. In case of input power or signal loss, – ISO7341: 1.2 mA (5 V Supplies), default output is 'low' for devices with suffix 'F' and 'high' for devices without suffix 'F'. See Device 0.9 mA (3.3 V Supplies) Functional Modes for further details. Used in – ISO7342: 1.3 mA (5 V Supplies), conjunction with isolated power supplies, these 0.9 mA (3.3 V Supplies) devices prevent noise currents on a data bus or other • Low Propagation Delay: 31 ns circuits from entering the local ground and interfering Typical (5 V Supplies) with or damaging sensitive circuitry. ISO734x has integrated noise filter for harsh industrial environment • 3.3 V and 5 V Level Translation where short noise pulses may be present at the • Wide Temperature Range: –40°C to 125°C device input pins. ISO734x has TTL input thresholds • 70 KV/ μs Transient Immunity, and operates from 3 V to 5.5 V supply levels. Typical (5 V Supplies) Through innovative chip design and layout techniques, electromagnetic compatibility of ISO734x • Robust Electromagnetic Compatibility (EMC) has been significantly enhanced to enable system- – System-level ESD, EFT, and Surge Immunity level ESD, EFT, Surge and Emissions compliance. – Low Emissions • Operates from 3.3 V and 5 V Supplies Device Information(1) ORDER NUMBER PACKAGE BODY SIZE • Wide Body SOIC-16 Package ISO7340C • Safety and Regulatory Approvals: ISO7340FC – 4242 VPK Basic Isolation per DIN V VDE V ISO7341C 0884-10 and DIN EN 61010-1 SOIC (16) 10.3mm x 7.50mm ISO7341FC – 3 KVRMS Isolation for 1 minute per UL 1577 ISO7342C – CSA Component Acceptance Notice 5A, IEC ISO7342FC 60950-1 and IEC 61010-1 End Equipment Standards (1) For all available packages, see the orderable addendum at the end of the datasheet. – GB4943.1-2011 CQC Certification Simplified Schematic 2 Applications • Optocoupler Replacement in: – Industrial Fieldbus – Profibus – Modbus – DeviceNetTM Data Buses – Servo Control Interface (1) VCCI and GNDI are supply and ground – Motor Control connections respectively for the input – Power Supplies channels. – Battery Packs (2) VCCO and GNDO are supply and ground connections respectively for the output. 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
