Supply TI Chip TCA9517DGKRQ1 Bidirectional Level Converter 8-VSSOP

Product Description

TCA9517DGKRQ1 is a bidirectional buffer with level shifting capabilities for I2C and SMBus systems. It supplies bidirectional voltage-level translation (up-translation and/or down-translation) between low voltages (down to 0.9 V) and higher voltages (2.7 V to 5.25 V) in mixed-mode applications. This device enables I2C and SMBus systems to be extended without loss of performance, even during level shifting.

TCA9517DGKRQ1 buffers both the serial data (SDA) and the serial clock (SCL) signals on the I2C bus, thus allowing two buses of up to 400-pF bus capacitance to be connected in an I2C application.
