General Description
The PCA9848 is an ultra-low voltage, octal bidirectional translating switch controlled via the I2C-bus.
The SCL/ SDA upstream pair fans out to eight downstream pairs, or channels.
Any or all SCx/SDx channels can be selected, determined by the programmable control register.
Key Features
- Ultra-low voltage operation, down to 0.8 V to interface with next-generation CPUs.
- 1-of-8 bidirectional translating switch.
- Fm+ I2C-bus interface logic; compatible with SMBus standards.
- Active LOW reset input.
- Two address pins allow up to 16 devices on the I2C-bus.
- Channel selection via I2C-bus.
- Power-up with all switch channels deselected.
- Low Ron switches.
- Allows voltage level translation between 0.8 V, 1.8 V, 2.
