General description
The PCA9549 provides eight bits of high speed TTL-compatible bus switching controlled by the I2C-bus. The low ON-state resistance of the switch allows connections to be made with minimal propagation delay. Any individual A to B channel or combination of channels can be selected via the I2C-bus, determined by the contents of the programmable Control register. When the I2C-bus bit is HIGH (logic 1), the switch is on and data can flow from Port A to Port B, or vice versa. When the I2C-bus bit is LOW (logic 0), the switch is open, creating a high-impedance state between the two ports, which stops the data flow.
Features
■ 8-bit bus switch (CBT)
■ 5 ? switch connection between two ports
■ I2C-bus interface logic; compatible with SMBus standards
■ Active LOW RESET input
■ 3 address pins allowing up to 8 devices on the I2C-bus
■ Bit selection via I2C-bus, in any combination
■ Power-up with all bits deselected
■ Low Ron switches
■ No glitch on power-up
■ Supports hot insertion
■ Low standby current
■ Operating power supply voltage range of 2.3 V to 5.5 V
■ 5 V tolerant inputs
■ 0 Hz to 400 kHz clock frequency
■ ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
■ Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
■ Packages offered: SO24, TSSOP24, HVQFN24
