A pin that is used by the analog and is
never driven by the device. Supplies are
part of this classification.
should not be driven by external sources.
A pin that is typically used for filtering a
DC signal within the device, Passive com-

Digital Inout—
Description
A pin that is used by the digital but is nev-
er driven.
should not be driven by another device to
avoid contention.
A pin that is either open drain (I2C_SDA)
or a bidirectional CMOS in/out. In the later
case the direction is selected by a control
register within the LM49370.
