It routes analog or digital signals up to 300 MHz bandwidth with a maximum on-resistance of 25 ohms, making it suitable for audio-path routing, signal multiplexing, and data-acquisition front-ends. The part operates from a single 2V to 11V supply and is specified over the industrial temperature range of -40°C to 85°C, so it fits both benchtop instrumentation and outdoor telecom or factory-floor gear. ## Key ratings and what they mean for the signal path The -108 dB crosstalk at 1 MHz isolates channels. The 7.5 pC charge injection affects sample-and-hold circuits. The 300 MHz bandwidth supports video or fast digital muxing. ## Package and rework consideration The 8-uMAX/uSOP package has a 3.00 mm body width. It is surface-mount only. ## Lifecycle and sourcing The MAX4733EUA+ carries an Active product status and is ROHS3 compliant. There is no official second-source or pin-compatible alternate listed in the manufacturer cross-reference, so for dual-sourcing resilience the buyer should qualify the part as a sole-source line item and plan buffer stock accordingly.","metaTitle":"MAX4733EUA+ Analog Switch, SPST-NO/NC, 25Ohm, 300MHz","metaDescription":"MAX4733EUA+ dual SPST analog switch, 25Ohm on-resistance, 300MHz bandwidth, -108dB crosstalk.
