The 275 ns turn-on and 200 ns turn-off times are fast enough for scanning sensor arrays or multiplexing signals at moderate rates, though not for high-speed video or RF switching. Crosstalk is rated at -62 dB at 1 MHz, which gives decent channel isolation for audio-band or low-frequency analog multiplexing; at higher frequencies it degrades, so keep that in mind for mixed-signal designs with fast edges nearby. Leakage current is a maximum of 500 pA off-state, and charge injection is 2 pC — both low enough that they won't disturb precision analog measurements in most data-acquisition or sample-and-hold circuits. The 10 pF / 14 pF channel capacitance (source off / drain off) is modest; it adds a small RC time constant with the source impedance, but for signals below a few hundred kHz it's rarely a concern. ## Package and handling It comes in a 16-pin SOIC-8 body (0.154\" wide, 3.90 mm width), surface-mount only. The '+' suffix on the order code indicates lead-free / ROHS3 compliant finish — no lead in the solder plating. It ships in a tube, not tape-and-reel, so if your pick-and-place line expects reels you'll need to transfer to tape or order the reel-pack variant. MSL is not listed in this data, but SOIC packages are typically MSL 1 or 2; still, bake before reflow if the moisture barrier bag has been open longer than the floor life. ## Lifecycle and sourcing It is ROHS3 compliant, so no restriction on use in new designs for RoHS-regulated markets. No official second source or pin-compatible alternate is listed in the record, so for dual-sourcing resilience you'd need to qualify a functionally similar part from another vendor on your own bench.","metaTitle":"MAX4509CSE+ Analog Devices SP4T Analog Switch, 2 Circuits","metaDescription":"MAX4509CSE+ dual SP4T analog switch from Analog Devices. 400 ohm R_on, 275ns switch time, -62dB crosstalk, 9V~36V single supply.
