Description
This TCA9509 integrated circuit is an I2C bus/SMBus Repeater for use in 12C/SMBus systems. It can
also provide bidirectional voltage-level translation (up-translation/down-translation) between low voltages
(down to 0.9 V) and higher voltages (2.7 V to 5.5V) in mixed-mode applications. This device enables
I2C 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 I2C bus, thus
allowing 400-pF bus capacitance on the B-side. This device can also be used to isolate two halves of a bus
for voltage and capacitance.
The TCA9509 has two types of drivers - A-side drivers and B-side drivers. All inputs and B-side l/Os are
overvoltage tolerant to 5.5 V. The A-side l/Os are overvoltage tolerant to 5.5 V when the device is unpowered
(VCCB and/or VCCA=0 V).
