.
Bi-directional. Serial data is transferred on the SMBus in both directions
using this pin.
Input. SMBus serial clock. Clocks data into and out of the TC1321.
Ground.
Output. Buffered DAC output voltage. This voltage is a function of the
reference voltage and the contents of the DATA register.
No connection.
Output. Unbuffered DAC output voltage. This voltage is a function of the
reference voltage and the contents of the DATA register. This output is
unbuffered and care must be taken that the pin is connected only to a
high-impedance node.
Positive power supply input. See electrical specifications.
