This Evaluation Board provides a complete isolated four-channel SPI node, plus an isolated 3.3 V to 5 V DC-to-DC convertor using an IL7817VE.
The board provides screw terminals for connections, plus test points for checking voltages and I/O. There are also LEDs to indicate DC-to-DC convertor input and output power. It uses a 2s2p board with thermal vias for optimal thermal performance.
The IL7817V is a high-speed, fully-isolated, data couplers with an integrated, one-quarter watt 3.3 V to 5 V DC-to-DC boost convertor. This level of integration dramatically reduces chip count and board area.
This Evaluation Board provides a complete isolated three-channel SPI node, plus an isolated 3.3 V to 3.3 V DC-to-DC convertor using an IL7614VE. It is ideal for half-duplex SPI applications.
These 2 x 3.5-inch (50 x 90 mm) boards also include screw terminal and test pads, and uses a 2s2p board with vias for optimal thermal performance. LEDs indicate DC-to-DC convertor input and output power.
The IL7614V is a high-speed, fully-isolated, data couplers with an integrated, one-quarter watt 3.3 V-to-3.3 V DC-to-DC convertor. This level of integration dramatically reduces chip count and board area.
The IL721VE is a 6 kVrms isolation, 125C, 3.3/5V, two channel, isolated, 110 Mbps, CMOS-compatible logic buffer with automatic level shifting, 10 ns propagation delay, 3 ns pulse width distortion, and 50 kV/microsecond transient immunity. 16-pin wide-body SOIC package with True 8™ mm creepage.
The "E" suffix indicates this part is lead (Pb) free.
The IL721T-3 is a high temperature, 3.3/5V dual-channel, bi-directional isolated buffer. Channel configuration is the reverse of the IL712T. 110 Mbps, CMOS compatible with automatic level shifting, 10 ns propagation delay, 3 ns pulse width distortion, 2500 Vrms isolation and 20 kV/microsecond transient immunity. 8-pin SOIC package.
The IL721-3 is a 3.3/5V, dual-channel bidirectional isolated buffer. The channel configuration is reversed from the IL712. CMOS-compatible with automatic level shifting, 110 Mbps, 10 ns propagation delay, 3 ns pulse width distortion, 2500 Vrms isolation and 20 kV/microsecond transient immunity. 8-pin SOIC package.
The "E" suffix indicates this part is lead (Pb) free.
The IL717VE is a 7 kVrms isolation, 125C, 3.3/5V, multi-channel, isolated, 110 Mbps, CMOS-compatible logic buffer with automatic level shifting, 10 ns propagation delay, 3 ns pulse width distortion, and 50 kV/microsecond transient immunity. 16-pin wide-body SOIC package with True 8™ mm creepage.
The "E" suffix indicates this part is lead (Pb) free.
These 2 x 3.5-inch (50 x 90 mm) boards have an IL717VE isolator, two bypass capacitors as recommended, screw connections, test pads, and provisions for header pins.
V-Series isolators are rated at a best-in-class 7 kVrms (9.9 kVpeak) isolation voltage. The evaluation board demonstrates best practice for maintaining 8 millimeter creepage. The isolators are conformally-coated to minimize arcing around the part.
