SCPS143G June 2009 – March 2021 PCA9548A
PRODUCTION DATA
When power (from 0 V) is applied to VCC, an internal power-on reset holds the PCA9548A in a reset condition until VCC has reached VPOR. At that point, the reset condition is released and the PCA9548A registers and I2C state machine initialize to their default states. After that, VCC must be lowered to below VPOR and then back up to the operating voltage for a power-reset cycle.
