TCA9617B Description
The TCA9617B is a BiCMOS dual bidirectional buffer intended for I2C bus and SMBus systems. The device provides bidirectional voltage-level translation (up-translation and down-translation) between low voltages (down to 0.8V) and higher voltages (2.2V 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.
