PCA9517 Datasheet Level-Translating I2C Bus Repeater

Manufacturer: Texas Instruments

General Description

This dual bidirectional I2C buffer is operational at 2.7 V to 5.5 V.

The PCA9517 is a BiCMOS integrated circuit intended for I2C bus and SMBus systems.

It can also provide bidirectional voltage-level translation (uptranslation/down-translation) between low voltages (down to 0.9 V) and higher voltages (2.7 V to 5.5 V) in mixed-mode applications.
