Description:

The BL714x is a high-performance four-channel digital isolator that

can achieve complete electrical isolation between inputs/outputs. Each isolated

channel's logic input and output buffers are isolated by a double-capacitance silicon dioxide (SiO2) barrier.

(SiO2) barrier, and the four data channels are completely independent, allowing the input data to be encoded.

The four data channels are completely independent, allowing input data to be encoded and recovered without distortion on the receiving end.

The BL7140 has four fully coaxial channels with output enable on the output side; the BL7140 has four fully coaxial channels with output enable on the output side.

The BL7140 device has four fully inverted channels with output enables on the output side; the BL7141 device has three forward channels and one inverted channel, both with output enables on the output side.

The BL7141 device has three forward channels and one reverse channel with output enables on both sides;

The BL7142 has two forward channels and two reverse channels with output enables on both sides.

BL7142 devices have two forward channels and two reverse channels with output enables on both sides. If the input side power or signal is lost, the device with the L suffix has an output enable on both sides.

If power or signal is lost on the input side, devices with the L suffix default to a low output and devices with the H suffix default to a high output.

The BL714x devices have a high

power consumption, providing high electromagnetic immunity and low emissions, which help prevent

noise and surges on the data bus or other circuits from entering the local earth

ground, which can interfere with or damage sensitive circuits, and high CMTI 

The BL714x devices are available in a 16-pin wide-body SMTI package.

The BL714x devices are available in 16-pin wide-body SOIC(W) and 16-pin SSOP(S) packages.
