MAX398CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX398CPE is a precision, monolithic CMOS analog multiplexer featuring eight bidirectional channels in a 16-pin Plastic DIP package. It operates with single +3V to +15V or bipolar ±3V to ±8V supplies. Key electrical parameters include an on-resistance of 280Ω maximum at +5V single supply and 14Ω maximum at ±5V dual supply, with channel matching within 13Ω. The device offers low off-leakage current (less than 2.5nA at +85°C), charge injection under 5pC, and transition times under 250ns. It provides rail-to-rail signal handling and TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPE' corresponds to the commercial temperature range (0°C to +70°C) and 16-pin Plastic DIP package configuration. Confirm that the ordering information matches the required pinout and thermal specifications for your application environment before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexer with low on-resistance flatness and precise channel matching is required. Ensure the system voltage falls within the +3V to +15V single or ±3V to ±8V dual supply limits. Consider the 280Ω max on-resistance at +5V single supply if operating under those conditions.
