PCA9548ABS,118
Brand: NXP Semiconductors
The PCA9548ABS,118 is an 8-channel I²C-bus switch that lets one host resolve address conflicts across multiple identical downstream devices, with voltage translation bridging 1.8 V, 2.5 V, 3.3 V and 5 V buses in one chip. A RESET input recovers a stuck bus, and hot-insertion support lets downstream boards be plugged in without disturbing the upstream bus.

Interface Features & Applications
- 8 downstream I²C channel pairs let one host resolve address conflicts across multiple identical devices
- Voltage translation between 1.8 V, 2.5 V, 3.3 V and 5 V buses bridges mixed-voltage subsystems
- RESET input recovers a stuck bus without a full power cycle
- Hot-insertion support allows downstream boards to be plugged in without disturbing the bus
- Three address pins let up to 8 PCA9548A devices share one upstream I²C bus
- 2.3 V to 5.5 V supply range fits most embedded system logic voltages
