PI6ULS5V9517A (Not Recommended for New Design (NRND))

Product 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.
