Description
General description
The PCA9543A is a bi-directional 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 the contents of the programmable control register. Two interrupt inputs, INT0 and INT1, one for each of the downstream pairs, are provided. One interrupt output, INT, which acts as an AND of the two interrupt inputs, is provided.
Features
• 1-of-2 bi-directional 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
