TI PCA9544ARGYR

4-to-1 bidirectional switching, compatible with I2C bus and SMBus. Four active-low interrupt inputs, active-low interrupt output. Three address pins, supporting up to eight devices on the I2C bus. Channel selection via I2C bus; all switch channels deselected at power-up. Low RON switches with voltage level translation between 1.8V, 2.5V, 3.3V, and 5V buses. No glitch at power-up, hot-insertion capable. Low standby current, operating supply voltage range 2.3V to 5.5V, 5.5V tolerant inputs, 0 to 400kHz clock frequency. Latch-up performance exceeds 100mA per JESD 78. ESD protection exceeds JESD 22 — 2000V Human Body Model (A114-A), 200V Machine Model (A115-A), 1000V Charged Device Model (C101).
