TI's ISO7820/ISO7820F dual-channel digital isolator at Mouser
Mouser Electronics is now stocking the ISO7820 and ISO7820F dual-channel digital isolators from Texas Instruments (TI). Engineered as high-performance, dual-channel digital isolators with 8000 VPK of isolation voltage and a signalling rate of up to 100Mbps, TI's ISO7820/ISO7820F isolators feature high electromagnetic immunity with low emissions at lower power-consumption levels, while isolating CMOS or LVCMOS digital I/Os. When used in conjunction with isolated power supplies, these devices prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry.
The Texas Instruments ISO7820 and ISO7820F dual-channel digital isolators provide two forward channels and no reverse-direction channel. Each isolation channel has a logic input and output buffer separated by a silicon dioxide (Si02) insulation barrier. These low power consumption devices are rated at 1.7mA (typical) per channel at 1Mbps, and offer a low propagation delay of 11ns (typical for 5V supplies). Maximum operating temperature for the devices is rated from -55degC to 125deg C. Other features of the ISO7820/ISO7820F devices include a CMTI of +/-100kV/us, a wide supply voltage range of 2.25V to 5.5V, a signalling rate of up to 100Mbps and an isolation barrier life of greater than 25 years.
TI's ISO7820/ISO7820F devices are backed by reinforced isolation certifications according to VDE, CSA and CQC. The advanced design and layout of the ISO7820/ISO7820F devices also help ease system-level electrostatic discharge (ESD), electric fast transient (EFT), surge, and emissions compliance. The ISO7820/ISO7820F devices are now available through Mouser Electronics in a wide-body (DW), 16-pin SOIC package, in both high (ISO7820) and low (ISO7820F) default output options. The devices are suitable for a variety of applications including industrial automation, motor control, power supplies, solar inverters, medical equipment, and hybrid electric vehicles.
