The PCA9543 Series is a bidirectional translating switch, controlled by the I2C-bus. The SCL/SDA upstream pair fans out to two downstream pairs, or channels. Any individual SCx/SDx channels or combination of channels can be selected, determined by thecontents of the programmable control register.
- 1-of-2 bidirectional translating switches
- I2C-bus interface logic; compatible with SMBus standards
- 2 active LOW interrupt inputs
- Active LOW interrupt output
- Active LOW reset input
- 2 address pins allowing up to 4 devices on the I2C-bus
- Channel selection via I2C-bus, in any combination
- Power-up with all switch channels deselected
- Low Ron switches
- Allows voltage level translation between 1.8 V, 2.5 V, 3.3 V and 5 V buses
- No glitch on power-up
- Supports hot insertion
- Low standby current
- Operating power supply voltage range of 2.3 V to 5.5 V
