Product details
Overview
The MAX398CPE+ from Maxim Integrated is an 8-channel precision CMOS analog multiplexer with low on-resistance (<100Ω), matched within 6Ω between channels, flat on-resistance (≤11Ω over signal range), and rail-to-rail signal handling. It operates from single +3V to +15V or bipolar ±3V to ±8V supplies, supports TTL/CMOS logic inputs, and delivers fast switching (tTRANS < 250ns) for use in battery-operated data-acquisition systems and automatic test equipment.
For engineers reviewing the MAX398CPE+ datasheet, MAX398CPE+ pinout, MAX398CPE+ application, or MAX398CPE+ equivalent, key selection criteria include guaranteed on-resistance matching, low charge injection (<5pC), NO/COM off-leakage <2.5nA at +85°C, ESD protection >2000V, and compatibility with DG408/DG508A pinouts in plastic DIP-16 packaging.
Technical Context
The MAX398CPE+ implements a monolithic CMOS switch architecture with silicon-gate process optimization to minimize charge injection and leakage across temperature. Its decoder-driven 3-bit address interface (A0–A2) selects one of eight bidirectional analog channels to connect to the common COM terminal, with independent enable (EN) control.
It maintains rail-to-rail analog signal handling under both single-supply (+3V to +15V) and dual-supply (±3V to ±8V) operation, with guaranteed flat on-resistance and low input loading due to CMOS logic inputs. The device is specified for 0°C to +70°C operation and packaged in 16-pin plastic DIP (P16-1).
Key Specifications

|---|---|---|
| 1, 15, 16 | A0, A1, A2 | 3-bit binary address inputs selecting one of eight analog channels (NO1–NO8) |
| 2 | EN | Active-high enable: disables all switches when low; required for break-before-make operation |
| 3 | V− | Negative supply rail (or GND in single-supply mode); sets lower analog signal limit |
| 4–7 | NO1–NO4 | Bidirectional analog inputs/outputs; routed to COM when selected |
| 8 | COM | Common analog I/O terminal; connects to selected NOx channel |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX398CSE+ | Narrow SOIC-16 package (S16-1); same electrical specs, smaller footprint, surface-mount only | Better suited for space-constrained PCBs where through-hole DIP is impractical | Select MAX398CSE+ when automated assembly and board density are priorities over manual prototyping or socketing. |
| ADG408BNZ | Analog Devices part; 8-channel, 25Ω typical RON, but higher charge injection (15pC) and no guaranteed RON matching spec | Acceptable for non-critical signal routing but not for precision sample-and-hold or metrology | Choose ADG408BNZ only if lower on-resistance outweighs need for tight matching and ultra-low charge injection in the target design. |
Compared with MAX398CSE+ and ADG408BNZ, the MAX398CPE+ uniquely combines DIP-16 through-hole reliability, guaranteed 6Ω RON matching, and <5pC charge injection-making it optimal for lab-grade test fixtures and repairable military subsystems where serviceability and precision coexist.

FAQ
What is the maximum analog signal range supported by the MAX398CPE+?
The MAX398CPE+ supports rail-to-rail analog signals from V− to V+, enabling ±4.5V operation with ±5V supplies or 0V to +4.5V with +5V single supply. Absolute maximum analog voltage is limited to (V− − 2V) to (V+ + 2V) per pin, with guaranteed performance across ±4.5V differential range. This allows full utilization of ADC input ranges in precision data-acquisition systems using the MAX398CPE+.
Does the MAX398CPE+ require external pull-up resistors on address or enable pins?
No, the MAX398CPE+ features CMOS-compatible digital inputs with defined logic thresholds (VIL ≤ 0.8V, VIH ≥ 2.4V) and low input current (<±0.1µA), eliminating need for external pull-ups. Direct connection to microcontroller GPIO or FPGA outputs is supported. The MAX398CPE+ internal structure ensures reliable switching without external biasing under standard operating conditions.
Can the MAX398CPE+ operate from a +3.3V single supply?
Yes, the MAX398CPE+ is fully specified for +3V to +15V single-supply operation. At +3.3V, on-resistance increases to ~425Ω (typical), transition time extends to ~575ns, and analog signal range reduces to ~0V–3.3V-but all functions remain operational with guaranteed leakage and logic compatibility. This makes the MAX398CPE+ viable for low-voltage portable instrumentation where the MAX398CPE+'s precision matching remains valuable despite higher RON.
How does the enable (EN) pin affect switching behavior in the MAX398CPE+?
The EN pin provides global enable/disable control: when low, all switches open regardless of address inputs, enforcing break-before-make timing during channel changes. When high, channel selection follows A0–A2. tON(EN) and tOFF(EN) are guaranteed ≤250ns and ≤200ns respectively, ensuring predictable timing in synchronous multiplexing systems using the MAX398CPE+.
Is the MAX398CPE+ pin-compatible with the DG408 in the same DIP-16 package?
Yes, the MAX398CPE+ is explicitly designed as a pin-compatible upgrade to the DG408 and DG508A in 16-pin plastic DIP (P16-1). Pin assignments for A0–A2, EN, COM, NO1–NO8, V+, V−, and GND match identically, allowing direct replacement without layout modification-while delivering superior specs including lower RON, tighter matching, and enhanced ESD protection in the MAX398CPE+.
