Product Description

The PCA9548APWR is a 8-channel I²C Switch with reset. The system master can reset the PCA9548A in the event of a timeout or other improper operation by asserting a low in the RESET input. Similarly, the power-on reset deselects all channels and initializes the I²C/SMBus state machine. Asserting RESET causes the same reset/initialization to occur without powering down the part. The pass gates of the switches are constructed so that the VCC pin can be used to limit the maximum high voltage, which is passed by the PCA9548A. This allows the use of different bus voltages on each pair, so that 1.8 or 2.5 or 3.3V parts can communicate with 5V parts, without any additional protection. External pull-up resistors pull the bus up to the desired voltage level for each channel. All I/O pins are 5V tolerant.
I²C and SMBus compatible
Channel selection via I²C bus
Power-up with all switch channels deselected
Low RON switches
No glitch on power up
Supports hot insertion
Low standby current
Latch-up performance exceeds 100mA per JESD 78
ESD protection exceeds JESD 22
Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
