Each of the four independent switches connects a common rail to a normally-open output when the corresponding control pin is driven high. The 45 ohm maximum on-resistance is flat across the signal range, and channel-to-channel matching holds to 500 mOhm — important for maintaining gain accuracy in multiplexed analog front-ends. Operating temperature is 0°C to 70°C, making this a commercial-grade part for indoor equipment, benchtop instruments, and consumer audio gear. Not rated for automotive or extended industrial environments. ## Switching speed and signal integrity Turn-on time is 100 ns maximum, turn-off is 75 ns maximum. That is fast enough for audio muting, relay replacement, and low-frequency analog muxing, but not for video crosspoint or high-speed data switching. The off-leakage current is just 100 pA maximum, so the switch does not load the signal path when disabled. Channel capacitance (both source and drain) is 9 pF each, which contributes to the bandwidth figure and also sets the settling time in a sample-and-hold application. The 1:1 multiplexer/demultiplexer circuit means each switch is a simple pass gate — no internal address decoding. ## Lifecycle and sourcing The MAX4066ACSD+T is listed as Active in production and ROHS3 compliant. No end-of-life notice or last-time-buy window has been issued. The part is sourced through independent distribution and quoted to order against an RFQ.","metaTitle":"MAX4066ACSD+T Analog Switch IC, SPST-NO x4, 45 Ohm, 14-SOIC","metaDescription":"MAX4066ACSD+T quad SPST-NO analog switch. 45 ohm on-resistance, -86 dB crosstalk at 1 MHz, 2 V to 16 V supply.
