It routes one channel with a 1:1 multiplexer/demultiplexer configuration, controlled by a digital logic input. The switch is designed for precision analog and digital signal gating where low on-resistance and fast switching matter. On-resistance is a maximum 2.5 Ohm across the rated supply range, which keeps signal attenuation minimal in audio or sensor paths. Channel-to-channel matching holds within 100 mOhm, so gain errors stay consistent when switching between identical signal legs. Switch times are 15 ns (turn-on) and 10 ns (turn-off), making this part suitable for multiplexing in data acquisition or test equipment where the sample window is in the tens of nanoseconds. Charge injection is 5 pC — low enough that a downstream sample-and-hold or ADC input sees negligible glitch energy. ## Supply and signal handling Operates from a single supply of 1.8 V to 5 V. Off-state leakage current is a maximum 250 pA. Channel capacitance in the off state is 17 pF on both source and drain sides. The part is specified over the industrial temperature range of -40°C to 85°C, covering outdoor telecom cabinets, factory-floor instrumentation, and test equipment. It does not carry an AEC-Q100 grade, so it is not qualified for automotive under-hood or chassis environments. ## Package and mounting Housed in an 8-uMAX/uSOP package (3.00 mm width, 0.118\" body), which is the same footprint as a standard MSOP-8 or TSSOP-8. The supplier device package is 8-uMAX/uSOP. Surface-mount assembly is assumed; the listed mounting type is Surface Mount. This part ships in a Tube — not tape-and-reel, so factor that into your pick-and-place feeder setup if you need reeled parts. The Tube quantity varies by manufacturer batch. For tape-and-reel, order MAX4645EUA+T. ## Lifecycle and sourcing ROHS3 compliant. Pricing and current availability are confirmed at quote time against an RFQ — no stock count or price is published here.","metaTitle":"MAX4645EUA+ SPST Switch, 2.5 Ohm, 8-uMAX","metaDescription":"MAX4645EUA+ SPST-NO analog switch, 2.5 Ohm max on-resistance, 5pC charge injection, -40°C to 85°C.
