That means one chip replaces eight discrete 2:1 mux packages or a larger 16-pin octal mux, saving board area and routing complexity on a 5 V bus. ## Package options and board-fit reality Both are surface-mount, so reflow profile and stencil aperture matter for solder-joint reliability on the narrow leads. No separate analog or core supply needed. ## Lifecycle and compliance — what the record says RoHS non-compliant. If your assembly line or customer requires RoHS-10 exemption-free parts, this mux will not pass. For legacy boards or mil/aero builds that still use tin-lead solder, it is a drop-in replacement.","metaTitle":"74FST32390Q 8 x 2:1 Multiplexer, 28-SSOP, Active","metaDescription":"74FST32390Q 8 x 2:1 multiplexer, 4.75V-5.25V supply, -40°C to 85°C, 28-SSOP/QSOP.
