Description:

The BL712x is a high-performance two-channel digital isolator that

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 two data channels are completely independent, allowing the input data to be encoded.

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

The BL7120 has two channels that are all in the same direction;

The BL7121 has one inverted channel and one forward channel.

The BL7121 has an inverted channel and a forward channel; the BL7122 has a forward channel and an inverted channel.

The BL7122 device has one forward channel and one reverse channel. If power or signal is lost on the input side, devices with the L suffix default to a low output and devices with the L suffix default to a low output.

L suffix outputs a low level by default, and the H suffix outputs a high

The BL712x devices have a high level of power and signal loss on the input side. 

The BL712x devices are highly insulated and provide high EMI immunity with low power consumption.

The BL712x devices' high insulation capability provides high electromagnetic immunity and low emissions with low power consumption, which helps 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 BL712x devices utilize an 8-pin narrow body.

The BL712x devices are available in 8-pin narrow-body SOP (A) and 8-pin wide-body SOW (B) packages.
