TI TCA9517DGKR

电压电平0.9 V ~ 5.5 V2.7 V ~ 5.5 V

Overview

The TCA9517is abidirectional buffer with level shifting capabilities for I2C and SMBussystems. It provides bidirectional voltage-level translation (up-translation/down-translation)between low voltages (down to 0.9 V) and higher voltages (2.7 V to 5.5 V) in mixed-modeapplications. This device enables I2C and SMBus systems to be extendedwithout degradation of performance, even during level shifting.
