7.1 PIN TYPE DEFINITIONS
Analog Input—
A pin that is used by the analog and is
never driven by the device. Supplies are
part of this classification.
Analog Output— A pin that is driven by the device and
should not be driven by external sources.
Analog Inout—
A pin that is typically used for filtering a
DC signal within the device, Passive com-
ponents can be connected to these pins.
Digital Input—
A pin that is used by the digital but is
never driven.
A pin that is driven by the device and
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 LM4935.
