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 components can be connected to these pins. Digital Input— A pin that is used by the digital but is never driven. Digital Output— A pin that is driven by the device and should not be driven by another device to avoid contention. Digital Inout— 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. These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
