Abstract

The operating power-supply voltage range of the TCA9548A-Q1 is 1.65 V to 5.25 V applied at the VCC pin. When the TCA9548A-Q1 is powered on for the first time or anytime the device must be reset by cycling the power supply, the power-on reset requirements must be followed to ensure the I2C bus logic is initialized properly.
