It lets a single upstream I²C master bus connect to two independent downstream buses, each with its own address space and pull-up resistors — useful when two devices share the same I²C address or when bus capacitance exceeds the 400 pF limit for standard-mode operation. ## Package and handling note Supplied in Bulk (tube or tray), not tape-and-reel — factor this into pick-and-place setup if your line is configured for reel-fed components. The 14-TSSOP footprint is standard; the 0.65 mm pitch demands a controlled solder-paste stencil and a reflow profile matching JEDEC MSL-1 (moisture sensitivity not explicitly stated, but TSSOP packages typically ship dry-packed).","metaTitle":"NXP PCA9542APW/DG118 I²C Mux 2-Ch 14-TSSOP","metaDescription":"NXP PCA9542APW/DG118 I²C multiplexer, 2-channel, 14-TSSOP.
