PCA9849
Overview
The PCA9849 is an ultra-low voltage, quad bidirectional translating multiplexer controlled via the I2C-bus. The SCL/SDA upstream pair fans out to four downstream pairs, or channels.
- Features and benefits
- Ultra-low voltage operation, down to 0.8 V to interface with next-generation CPUs
- 1-of-4 bidirectional translating multiplexer
- Fm+ I2C-bus interface logic; compatible with SMBus standards
- Active LOW reset input
- 2 address pins allowing 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, 2.5 V and 3.3 V buses
