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.","metaTitle":"NXP PCA9541ABS/03,118 I2C Multiplexer, 2.3V–5.5V","metaDescription":"NXP PCA9541ABS/03,118 2-channel I2C/SMBus multiplexer in 16-HVQFN. 2.3V–5.5V supply.
