Description
The PI6ULS5V9517A is a CMOS integrated circuit
intended for I²C-bus or SMBus applications. It can
provide level shifting between low voltage (down to 0.8
V) and higher voltage (2.2V to 5.5V) in mixed-mode
applications. And it enables I²C and similar bus system
to be extended, without degeradation of peformance
even during level shifting.
The PI6ULS5V9517A enables the system designer to
isolate two halves of a bus for both voltage and
capacitance, accommodating more I²C devices or longer
trace length. It also permits extension of the I²C-bus by
providing bidirectional buffering for both the data (SDA)
and the clock (SCL) lines, thus allowing two buses of
400 pF to be connected in an I²C application.
