Each channel routes one of four analog inputs to a common output, controlled by separate digital address lines. The 100Ohm max on-resistance stays matched within 1.5Ohm channel-to-channel, which keeps gain errors predictable across the multiplexed path. Switching completes in 150ns — fast enough for moderate-speed data acquisition or audio routing, but not for video-rate signals. Supply flexibility is the headline: run it off a single rail from 5V to 30V, or split ±5V to ±20V. That single-supply range means you can drop it into a 5V logic system or a 24V industrial analog front-end without a separate negative rail. The commercial temperature grade (0°C to 70°C) limits it to indoor, controlled environments — think lab instruments, benchtop test gear, or office-equipment signal routing. Not for automotive or outdoor telecom enclosures. ## Signal integrity specs — what they mean for your analog path Crosstalk sits at -92dB at 100kHz. Off-leakage current is 750pA maximum. Charge injection is 2pC. Channel off-capacitance is 26pF on the drain side. ## Active production — no LTB clock ticking The MAX309CSE+ carries an Active lifecycle status. That means no last-time-buy window to chase, no end-of-life paperwork to file. This is a current-production part you can qualify into a new BOM without worrying about a surprise EOL notice next quarter. RoHS3 compliant, so it passes EU and most global environmental requirements without an exemption hunt. ## Sourcing reality This part is sourced through independent distribution channels. No minimum quantity barrier — we can quote small lots for prototype builds or production volumes.","metaTitle":"MAX309CSE+ Dual SP4T Analog Multiplexer, 100Ohm, 16-SOIC","metaDescription":"Maxim MAX309CSE+ dual SP4T analog multiplexer. 100Ohm on-resistance, 150ns switching, single/dual supply.
