Product details

Dual SPST-NO switch with 100ns switching and -90dB crosstalk

It switches two independent signal paths on or off with a 1:1 multiplexer/demultiplexer configuration, meaning each channel is a simple pass gate — no routing, just connect or disconnect. Key parametrics: 60 ohm max on-resistance with 800 milliohm channel-to-channel matching, 100ns turn-on and 75ns turn-off times, -90dB crosstalk at 1MHz, and 1pC charge injection. The supply range spans 2.7V to 12V single supply, covering both 3.3V and 5V logic systems without an extra regulator. Leakage current is 100pA max off-state, and channel capacitance is 8pF on both sides — low enough for audio paths and moderate-speed analog sampling.

The 8-SOIC package (0.154" body width, 3.90mm) is a rework-friendly footprint. The surface-mount body has low thermal mass, so a standard 300°C hot-air profile lifts it cleanly without cooking adjacent passives.

Sourcing posture

Frequently asked questions

Where can I buy MAX4541ESA+T and what is the price?

The MAX4541ESA+T is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at the time of quotation — submit an RFQ for a firm price and lead time.

Can MAX4541ESA+T be used for audio switching?

Yes, with -90dB crosstalk at 1MHz and 1pC charge injection, the MAX4541ESA+T is well suited for audio signal routing where low distortion and channel isolation matter. The 60 ohm on-resistance is acceptable for line-level audio paths driving high-impedance loads.

Is MAX4541ESA+T compatible with 3.3V logic?

Yes, the 2.7V to 12V supply range includes 3.3V operation. The logic inputs are CMOS-compatible and will switch cleanly with 3.3V control signals.

What are equivalent parts for MAX4541ESA+T?

The MAX4541ESA+T is a dual SPST-NO analog switch in 8-SOIC. Pin-compatible alternatives from the same function class include the MAX4541CSA+ (same die, commercial temperature range 0°C to 70°C) and the MAX4541EPA+ (same die, PDIP package). For a dual SPST with different performance trade-offs, parts like the DG411 or ADG1411 are functional alternatives but verify pinout and package before substitution.
