Bias is provided by 4.7kΩ pull-up/down resistors on
the Data-In lines. This value is adequate for most
applications without termination. If another value is
required, space is provided on the PC for through-hole
resistor placement (R12, R21, R14, and R23).
Biasing application notes are also available on the
website.
