The MAX20327EWL+T: The -3dB bandwidth of 100MHz sets the usable signal ceiling — the switch passes a 100MHz clock or video signal with 3dB of attenuation at the band edge; below 10MHz the insertion loss is well under 0.5dB. Crosstalk is rated at -100dB at 100kHz, meaning less than 10µV of the signal on one channel couples into the other at a 1V reference — this is the spec that makes the part suitable for switching sensitive analog signals alongside a digital bus without audible bleed-through.
Package and board-fit for the WLP footprint
The 9-WLP package (1.61x1.61mm body) is a wafer-level chip-scale package with solder balls on a 0.50mm pitch — the footprint is the die itself, so no plastic overmold adds height. The 9-ball array maps to one DPDT switch with a common supply pin; the datasheet's recommended land pattern matches the ball layout exactly, and the 0.35mm ball diameter requires a solder-mask-defined pad on the PCB. Surface-mount assembly is standard reflow; the package is moisture-sensitive, so a bake before reflow is needed if the reel has been exposed to ambient humidity beyond the floor life.
Supply range and switching performance
The turn-on time is 300µs max, turn-off is 30µs max, which is fast enough for audio source selection, sensor multiplexing, or power-rail sequencing but not for high-speed digital switching like USB 2.0 signal routing (that needs sub-10ns). Leakage current in the off state is 1µA max, and channel capacitance is 4pF per port, so the off-isolation at 1MHz is dominated by the capacitive feedthrough rather than the DC leakage.
Temperature grade and sourcing posture
The part is RoHS3 compliant and supplied on Tape & Reel in the standard 7-inch reel quantity for the WLP package.
