The 300 MHz bandwidth passes signals up to that frequency with only 3 dB of roll-off. The -90 dB crosstalk at 1 MHz means adjacent channels won't bleed into each other.
The part comes in a 24-TQFN (4x4 mm) with an exposed pad. Surface-mount only.
The -3 dB bandwidth is 300 MHz, which means the switch passes signals up to that frequency with only 3 dB of attenuation. This is well above the needs of video, 100BASE-TX, or audio muxing.
The maximum on-resistance is 5.5 ohms. Channel-to-channel matching is within 300 milliohms, so the path impedance stays consistent across all six SPDT switches.
The listed package is Tube. The tape-and-reel variant is typically ordered as MAX4948ETG+T — confirm the suffix when placing your order if your assembly line requires reel feed.
