Product details

Supply voltage and switching — dual-rail or single, 1.5µs turn-on

This mux switches in 1.5µs max (turn-on) and 1µs max (turn-off). That is fast enough for audio-band multiplexing, sensor scanning at tens of kHz, and relay-replacement in ATE, but not for video or RF switching. The channel-to-channel on-resistance matching is 70Ohm — not tight enough for precision gain-setting, but fine for routing signals where absolute resistance tolerance is relaxed. Channel capacitance is 1.8pF off-state and 8pF off-state on the common node, which keeps settling time manageable with moderate source impedances.

Package and mounting — 16-TQFN with exposed pad

Surface-mount 16-TQFN exposed pad (5x5 mm body). The exposed pad must be soldered to a ground plane for thermal and electrical contact.

Frequently asked questions

What is the substitute or equivalent for MAX328ETE+?

The MAX328ETE+ is an active part with no official replacement announced. If a second source is needed, look for 8:1 analog multiplexers in a 16-TQFN package with similar supply range and charge injection — but verify pin compatibility and on-resistance against the datasheet.
