2.4. 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 6 on page 16 and Table 7 on page 17 detail the
working voltage and creepage/clearance capabilities of the Si84xx. 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, etc.)
requirements before starting any design that uses a digital isolator.
2.4.1. Supply Bypass
The Si84xx family requires a 1 µF bypass capacitor between V
and GND1 and V
and GND2. The capacitor
DD1
DD2
should be placed as close as possible to the package. To enhance the robustness of a design, it is further
recommended that the user include 100 resistors in series with the inputs, outputs, and supply pins if the system
is excessively noisy. See "3. Errata and Design Migration Guidelines" on page 27 for more details.
2.4.2. Output Pin Termination
The nominal output impedance of an isolator driver channel is approximately 85 , ±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.
