Product details

2-channel I2C bus selector in a 4x4 HVQFN

The NXP PCA9541ABS/03,118 is a 2-channel I2C multiplexer that lets a single master communicate with two independent I2C or SMBus segments, selecting one at a time through the control register.

Supply range and bus compatibility

The I2C and SMBus interface support standard-mode (100 kHz) and fast-mode (400 kHz) clock rates, so it works with most MCU I2C peripherals and SMBus controllers. The bus capacitance per channel is isolated when deselected, which helps keep rise times within spec on long or heavily loaded buses.

No end-of-life notification or last-time-buy window is currently in effect.
