Product details

What this 8:1 CMOS multiplexer does

The Maxim Integrated MAX4051AEEE+ is a single-ended 8:1 analog multiplexer/demultiplexer in a 16-pin QSOP package. It routes one of eight analog inputs to a common output (or the reverse as a demultiplexer) with a maximum on-resistance of 100 ohms and channel-to-channel matching held to 6 ohms max. The switch topology is break-before-make, so the output never sees two inputs shorted during transition. It runs on a single supply from 2 V to 16 V, or dual supplies from ±2.7 V to ±8 V. The industrial temperature range of -40°C to +85°C suits it for factory-floor signal conditioning, data-acquisition front-ends, and telecom line cards that see outdoor enclosure temperatures. Key specs for analog signal integrity: -90 dB crosstalk at 100 kHz; 2 pC charge injection; off-leakage is 100 pA max.

Lifecycle and sourcing posture

The MAX4051AEEE+ carries an Active lifecycle status and is ROHS3 compliant (lead-free).

Frequently asked questions

How many channels does MAX4051AEEE+ have?

It is a single 8:1 multiplexer/demultiplexer — one common output and eight selectable inputs (or the reverse direction).

Can MAX4051AEEE+ be used as a demultiplexer?

Yes. The 8:1 circuit is bidirectional — route the common pin to one of eight outputs by setting the address lines.

What is the difference between MAX4051AEEE+ and MAX4051AEEE+T?

The suffix 'T' indicates tape-and-reel packaging; the MAX4051AEEE+ ships in tubes. The die and electrical specifications are identical.

Is MAX4051AEEE+ equivalent to DG408?

Both are 8:1 single-ended CMOS multiplexers with similar pinouts, but verify the supply range and on-resistance against your design. The MAX4051AEEE+ runs from 2 V to 16 V single or ±2.7 V to ±8 V dual, with 100 ohm max on-resistance. Check the DG408 datasheet for its own ratings — they are not guaranteed drop-in equivalents without a pin-to-pin and spec review.
