3.3. Layout Recommendations
To ensure safety in the end user application, high voltage circuits (i.e., circuits with >30 V
) must be physically
AC
separated from the safety extra-low voltage circuits (SELV is a circuit with <30 V
) by a certain distance
AC
(creepage/clearance). If a component, such as a digital isolator, straddles this isolation barrier, it must meet those
creepage/clearance requirements and also provide a sufficiently large high-voltage breakdown protection rating
(commonly referred to as working voltage protection). Table 5 on page 14 and Table 6 on page 14 detail the
working voltage and creepage/clearance capabilities of the Si86xx. These tables also detail the component
standards (UL1577, IEC60747, CSA 5A), which are readily accepted by certification bodies to provide proof for
end-system specifications requirements. Refer to the end-system specification (61010-1, 60950-1, 60601-1, etc.)
requirements before starting any design that uses a digital isolator.
3.3.1. Supply Bypass
The Si866x family requires a 0.1 µF bypass capacitor between V
and GND1 and V
and GND2. The
DD1
DD2
capacitor should be placed as close as possible to the package. To enhance the robustness of a design, it is further
recommended that the user also add 1 µF bypass capacitors and include 100 resistors in series with the inputs
and outputs if the system is excessively noisy.
3.3.2. Pin Connections
For narrow-body devices, Pin 2 and Pin 8 GND must be externally connected to respective ground. Pin 9 and Pin
15 must also be connected to external ground. No connect pins are not internally connected. They can be left
floating, tied to VDD, or tied to GND.
3.3.3. Output Pin Termination
The nominal output impedance of an isolator driver channel is approximately 50 , ±40%, which is a combination
of the value of the on-chip series termination resistor and channel resistance of the output driver FET. When driving
loads where transmission line effects will be a factor, output pins should be appropriately terminated with controlled
impedance PCB traces.
3.4. Fail-Safe Operating Mode
Si86xx devices feature a selectable (by ordering option) mode whereby the default output state (when the input
supply is unpowered) can either be a logic high or logic low when the output supply is powered. See Table 12 on
page 20 and "5. Ordering Guide" on page 26 for more information.
