Product details

What this 8:1 mux does on the board

The Maxim Integrated MAX398CPE+ is a single 8-channel analog multiplexer in a 16-pin DIP package. It routes one of eight analog inputs to a common output, controlled by a 3-bit address. On-resistance is 100 Ohm max, which matters when you are switching low-level signals into an ADC or op-amp front end — that series resistance forms a voltage divider with the input impedance of the next stage. Switching is 150 ns each way, fast enough for most data-acquisition scan rates below a few hundred kHz. The -92 dB crosstalk at 100 kHz keeps adjacent channels from bleeding into each other in precision applications like ATE pin electronics or medical instrumentation front-ends.

Supply range and signal headroom

Single-supply operation from 3 V to 15 V. Dual supplies ±3 V to ±8 V. Off-leakage is 100 pA max. Charge injection is 2 pC.

Package and temperature grade

The 16-DIP (0.300", 7.62 mm) through-hole package is the standard footprint for breadboarding and legacy board rework. It is not a space-saving option — this is a through-hole part for designs where manual rework or socketed prototyping is expected. The 0 °C to 70 °C commercial temperature range fits benchtop instrumentation, lab equipment, and indoor industrial control panels. Not rated for under-hood automotive or outdoor telecom cabinets.

Channel matching and capacitance

Channel-to-channel on-resistance matching is 6 Ohm max. Off-channel capacitance is 11 pF on the source side and 40 pF on the drain side.

Frequently asked questions

Where can I buy MAX398CPE+?

The MAX398CPE+ is sourced through independent distribution and can be quoted to order against an RFQ. Availability and current pricing are confirmed at the time of quotation.

What is the on-resistance of MAX398CPE+?

The maximum on-resistance is 100 Ohm. Channel-to-channel matching is 6 Ohm max, so the Ron variation across the eight inputs stays tight for consistent signal attenuation.

Is MAX398CPE+ RoHS compliant?

Yes, it is RoHS3 compliant. The part is lead-free and meets the current EU RoHS directive.

What is the crosstalk specification of MAX398CPE+?

Crosstalk is -92 dB at 100 kHz. That figure tells you how much of an adjacent channel's signal leaks into the selected channel — important for multi-channel precision analog systems.

What package does MAX398CPE+ come in?

It is supplied in a 16-pin DIP package (0.300", 7.62 mm body width), through-hole mounting. The supplier device package is 16-PDIP. It ships in Tube packaging.
