Product details
Overview
MAX399CPE+ from Maxim Integrated is a dual 4-channel CMOS analog multiplexer designed for precision signal routing in low-voltage systems. It delivers <100Ω on-resistance, <6Ω channel-to-channel matching, <5pC charge injection, and operates from ±3V to ±8V or +3V to +15V supplies. It serves as a rail-to-rail, low-leakage switch in battery-operated data-acquisition and military radio front-ends.
For engineers reviewing the MAX399CPE+ datasheet, MAX399CPE+ pinout, MAX399CPE+ application, or MAX399CPE+ equivalent, key selection criteria include guaranteed on-resistance flatness (<11Ω), NO/COM off-leakage <2.5nA at +85°C, break-before-make timing (90–245ns), TTL/CMOS logic compatibility, and pin compatibility with DG409/DG509A.
Technical Context
The MAX399CPE+ implements a dual independent 4:1 analog multiplexer architecture with separate COMA/COMB outputs and shared address (A0, A1) and enable (EN) control. Each 4-channel section selects one of four bidirectional analog inputs (NO1A–NO4A or NO1B–NO4B) to its respective common terminal under digital address decoding.
It uses Maxim's low-voltage silicon-gate CMOS process to achieve low charge injection (<5pC), ESD protection >2000V, and rail-to-rail analog signal handling across its full supply range. Switching is controlled by CMOS-compatible inputs with defined VIH/VIL thresholds (2.4V/0.8V) and sub-250ns transition time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | <100Ω typical at ±5V - ensures minimal signal attenuation and gain error in precision measurement paths |
| RON Matching | <6Ω max between channels - enables accurate ratiometric measurements and matched gain in differential or multi-channel systems |
| Charge Injection | <5pC - reduces voltage glitch and settling error in sample-and-hold and switched-capacitor circuits |
| Off-Leakage Current | <2.5nA at +85°C (COM/NO) - preserves high-impedance node integrity in low-power sensor interfaces |
| Analog Signal Range | Rail-to-rail: V− to V+ - supports full dynamic range utilization without level-shifting in bipolar or single-supply designs |
| Supply Range | +3V to +15V single or ±3V to ±8V dual - enables operation in battery-powered, industrial, and military platforms |
| Transition Time | <250ns - meets timing requirements for medium-speed data acquisition and automated test equipment |
Pinout & Package
MAX399CPE+ is housed in a 16-pin plastic DIP (dual in-line package), 0.300" wide, with pin 1 marked by notch or dot. The exposed pad (EP) is absent in this DIP variant - only present in QFN versions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 (Address Inputs) | Digital select lines determining which of four analog inputs connects to COMA or COMB; TTL/CMOS compatible |
| 2 | EN (Enable) | Active-high global enable: disables all switches when low, preventing unintended conduction during power-up or reset |
| 3 | V− | Negative supply rail - must be connected for dual-supply operation; tied to GND for single-supply use |
| 4–7 | NO1A–NO4A | Bidirectional analog inputs for first 4:1 mux section - support signal routing in either direction with matched RON |
| 8, 9 | COMA, COMB | Independent common terminals - allow simultaneous routing of two separate analog signals without crosstalk |
| 10–13 | NO1B–NO4B | Bidirectional analog inputs for second 4:1 mux section - electrically isolated from NO1A–NO4A section |
| 14 | V+ | Positive supply rail - sets upper bound of analog signal range and powers internal logic and switch drivers |
| 15 | GND | Logic and analog reference ground - must be low-impedance; separates digital return from sensitive analog returns in layout |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 architecture | Enables concurrent routing of two analog signals (e.g., I/Q paths, dual ADC inputs) without shared resource contention |
| Guaranteed RON flatness <11Ω | Maintains consistent gain and linearity across full analog input range (±4.5V), critical for precision instrumentation |
| Low leakage <2.5nA at +85°C | Preserves accuracy in high-impedance sensor nodes and long-hold sample-and-hold circuits over temperature |
| Pin compatibility with DG409/DG509A | Allows drop-in replacement in legacy designs without PCB revision, reducing qualification and redesign effort |
| ESD protection >2000V HBM | Reduces need for external protection components in field-deployed systems subject to handling or environmental stress |
Applications
| Sample-and-Hold Circuits | Automatic Test Equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX399CEE+ | QSOP-16 package (4.4mm width); identical electrical specs and pinout; lower profile, surface-mount compatible | Better suited for space-constrained PCBs and automated assembly; no through-hole mounting required | Select MAX399CEE+ for new SMT designs requiring smaller footprint and reflow compatibility. |
| ADG409BNZ | 44Ω typical RON at ±15V; higher leakage (10nA @ +85°C); not pin-compatible; requires layout change | Acceptable where higher on-resistance and leakage are tolerable, e.g., non-precision audio routing | Choose ADG409BNZ only if cost or availability drives substitution and performance trade-offs are validated. |
Compared with MAX399CPE+, MAX399CEE+ offers identical functionality in a surface-mount package for modern assembly, while ADG409BNZ provides functional equivalence at relaxed precision but requires PCB redesign and delivers higher on-resistance and leakage.

FAQ
What supply voltages does the MAX399CPE+ support?
The MAX399CPE+ operates from a single +3V to +15V supply (with V− tied to GND) or dual ±3V to ±8V supplies. At ±5V, it achieves <100Ω on-resistance and <5pC charge injection. Operation at ±3V increases RON to ~425Ω but retains full functionality for ultra-low-power applications.
Is the MAX399CPE+ pin-compatible with industry-standard multiplexers?
Yes, the MAX399CPE+ is pin-compatible with the DG409 and DG509A analog multiplexers. Its pinout matches these legacy devices exactly in the 16-pin DIP package, enabling direct replacement without PCB modification or firmware changes.
How does the MAX399CPE+ handle leakage current at elevated temperatures?
The MAX399CPE+ guarantees COM and NO off-leakage current <2.5nA at +85°C - tested 100% at maximum rated hot operating temperature. This ensures reliable high-impedance signal integrity in military and industrial environments where thermal drift must be minimized.
What is the break-before-make interval for the MAX399CPE+?
The MAX399CPE+ features a guaranteed break-before-make interval of 90ns to 245ns (depending on supply and temperature), preventing momentary shorting between channels during address transitions. This protects sensitive sources and loads from transient current surges.
Does the MAX399CPE+ require external protection diodes for overvoltage?
No - the MAX399CPE+ includes internal protection diodes. However, if absolute maximum ratings risk being exceeded (e.g., uncontrolled power sequencing), external series diodes may be added to V+ and V−. Note that this reduces analog signal range by ~1.4V and is not recommended for single-supply operation.
