Digital Isolator SOP16

The YINGHUA SI8663BD-B-IS is a digital isolator in a 16-pin SOP package designed for circuit designs that require galvanic isolation between logic domains. It suits engineers building industrial, automotive or power-supply boards where signal integrity across isolation barriers is critical.

16-pin package capacity

The 16-pin SOP footprint provides the pin count needed for multi-channel isolation with power and ground connections. Designs needing more channels or a smaller footprint will require a different package or a higher-density isolator series.

Replaces older optocoupler layouts

This isolator upgrades boards that currently use discrete optocouplers by integrating isolation in a single IC, reducing board area and component count. The jump is worthwhile when a design can use the standard SOP16 pin-out and does not need specialised timing or voltage levels beyond the device rating.

Questions about this item

Does the SOP16 footprint of the SI8663BD-B-IS match the 16-pin layout on my existing PCB?

The SI8663BD-B-IS is supplied in a 16-pin SOP16 surface-mount package; verify your board's land pattern against the manufacturer's mechanical drawing before assembly.

How can I confirm the SI8663BD-B-IS is functioning after soldering it to the board?

Apply power within the specified supply range, toggle the input channels and measure the corresponding output pins for correct logic levels and isolation barrier integrity.

What comes in the box with the SI8663BD-B-IS and what must I source separately?

The package contains the SI8663BD-B-IS digital isolator in SOP16 form; solder paste, flux, decoupling capacitors and any required PCB are not included and must be purchased separately.
