电平转换FM I2C总线中继器 LEVEL-TRANSLATING FM I2C BUS REPEATER

The TCA9617A is a BiCMOS dual bidirectional buffer intended for I2C bus and SMBus systems. It can provide bidirectional voltage-level translation up-translation and down-translation between low voltages down to 0.8 V and higher voltages 2.2 V to 5.5 V in mixed-mode applications. This device enables I2C and similar bus systems to be extended, without degradation of performance even during level shifting.

The TCA9617A buffers both the serial data SDA and the serial clock SCL signals on the I2C bus, allowing two buses of 550-pF or greater bus capacitance to be connected in an I2C application. This device can also be used to isolate two halves of a bus for voltage and capacitance.
