TCA9509 Level Translating I2C/SMBus Bus Repeater
Texas Instruments TCA9509 I 2 C Bus / SMBus Repeater is designed for use in I 2 C/SMBus systems. The TCA9509 can also provide bidirectional voltage-level translation (up-translation/down-translation) between low voltages (down to 0.9V) and higher voltages (2.7V to 5.5V) in mixed-mode applications. This device enables I 2 C and similar bus systems to be extended, without degradation of performance even during level shifting. The TCA9509 buffers both the serial data (SDA) and the serial clock (SCL) signals on the I 2 C bus, allowing 400pF bus capacitance on the B-side. This device can also be used to isolate two halves of a bus for voltage and capacitance. The Texas Instruments TCA9509 has two types of drivers - A-side drivers and B-side drivers. All inputs and B-side I/Os are over-voltage tolerant to 5.5V. The A-side I/Os are overvoltage tolerant to 5.5V when the device is unpowered (V CCB and/or V CCA =0V).
