Product details
Overview
MAX399EPE+ from Maxim Integrated is a precision dual 4-channel CMOS analog multiplexer designed for bidirectional signal routing in low-voltage, high-accuracy data-acquisition systems. It delivers <100Ω on-resistance, <6Ω channel-to-channel RON matching, <5pC charge injection, ±3V to ±8V bipolar or +3V to +15V single-supply operation, and rail-to-rail analog signal handling up to ±4.5V - enabling reliable signal switching in battery-powered test equipment and military-grade guidance interfaces.
For engineers reviewing the MAX399EPE+ datasheet, MAX399EPE+ pinout, MAX399EPE+ application, or MAX399EPE+ equivalent, this page provides verified specifications, validated pin functions, confirmed dual 4-channel switching topology, temperature-stable leakage performance (<2.5nA COM off-leakage at +85°C), and direct alternatives with documented functional alignment for sample-and-hold, audio routing, and PBX signal path design.
Technical Context
The MAX399EPE+ implements a CMOS transmission-gate architecture with independent address decoding (A0/A1) and global enable (EN) control, supporting simultaneous selection of one channel per 4-channel bank (COMA/NO1A–NO4A and COMB/NO1B–NO4B). Its substrate tied to V+ ensures stable threshold behavior across supply ranges.
It guarantees flat on-resistance (<11Ω variation over ±4.5V signal range) and low dynamic errors: transition time <250ns, break-before-make interval 90–245ns, and crosstalk <−75dB - all specified under dual ±5V and single +5V conditions with full −40°C to +85°C industrial temperature qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual 4-channel analog multiplexer: two independent banks (A and B), each with 4 inputs and 1 common I/O terminal |
| On-resistance (RON) | <100Ω typical at +25°C, ±5V supplies - ensures minimal signal attenuation and gain error in precision sensor front-ends |
| RON matching | <6Ω max between channels - critical for matched gain paths in differential instrumentation and automatic test equipment |
| Charge injection | <5pC max - limits voltage glitch on sampled nodes, enabling sub-12-bit accuracy in sample-and-hold circuits |
| Off-leakage (COM) | <2.5nA at +85°C - preserves integrity of high-impedance sensor outputs and long-time-constant integrators |
| Supply range | +3V to +15V single supply or ±3V to ±8V dual supply - supports portable, automotive, and industrial power architectures |
| Logic compatibility | TTL/CMOS-input compatible (VIL ≤ 0.8V, VIH ≥ 2.4V) - interoperable with FPGA, MCU, and ASIC control without level-shifting |
Pinout & Package
MAX399EPE+ is supplied in a 16-pin plastic DIP (P16-1) package with through-hole mounting and standard 0.300" wide body. Pin 1 is top-left corner (A0), pin 16 is top-right corner (V+), and pin 9 is bottom-right corner (COMB).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1 | Binary address inputs | Selects active channel (0–3) within each 4-channel bank; logic-compatible with 3V/5V controllers |
| EN | Global enable input | High-active control: disables both banks simultaneously when low - essential for power gating and fault isolation |
| COMA, COMB | Common bidirectional terminals | Shared I/O ports per bank; support rail-to-rail analog signals up to ±4.5V with low distortion |
| NO1A–NO4A, NO1B–NO4B | Analog channel inputs/outputs | Bidirectional, low-capacitance (≤11pF off-capacitance) paths - minimize loading on source/sink circuits |
| V+, V−, GND | Power supply connections | V+ and V− set analog signal range; GND reference required for single-supply operation (V− = GND) |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible replacement | Direct drop-in for DG409 and DG509A - enables legacy system upgrades without PCB redesign |
| Rail-to-rail signal handling | Supports analog voltages from V− to V+ (±4.5V typical) - eliminates external biasing in unipolar/bipolar sensor interfaces |
| Guaranteed flat RON | <11Ω variation over full signal range - maintains consistent channel gain and settling time across input amplitude |
| ESD robustness | >2000V HBM - sustains handling and board-level stress in manufacturing and field service environments |
| Low power consumption | <300µW typical at +25°C - extends battery life in portable ATE and handheld diagnostic tools |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-channel analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX399EEE+ | Same electrical specs; QSOP-16 package (5.3mm × 10.2mm) vs. DIP-16 (19.1mm × 6.6mm) | Better suited for space-constrained PCB layouts; requires rework for hand-soldered prototyping | Select for automated SMT assembly where footprint density matters more than through-hole serviceability. |
| ADG409BNZ | Higher RON (100Ω typ. vs. 85Ω typ.), no guaranteed RON matching spec, −40°C to +85°C rated | Acceptable for non-critical audio routing but not for precision metrology requiring channel matching | Choose only when cost sensitivity outweighs need for <6Ω matching and <5pC charge injection. |
Compared with MAX399EPE+, MAX399EEE+ offers identical performance in a smaller surface-mount package, while ADG409BNZ trades guaranteed matching and ultra-low charge injection for broader vendor availability - making MAX399EPE+ optimal for ruggedized, high-fidelity signal routing where channel consistency is mandatory.

FAQ
What is the maximum analog signal range supported by the MAX399EPE+?
The MAX399EPE+ supports rail-to-rail analog signals from V− to V+. With ±5V supplies, the usable range is ±4.5V; with +5V single supply (V− = GND), it handles 0V to 4.5V. This is confirmed in the Electrical Characteristics tables for both dual-supply and single-supply operation modes, and applies directly to the MAX399EPE+ under its −40°C to +85°C rating.
Is the MAX399EPE+ pin-compatible with the DG409 analog multiplexer?
Yes, the MAX399EPE+ is explicitly specified as pin-compatible with the industry-standard DG409 and DG509A. Pin mapping for A0, A1, EN, COMA, COMB, NO1A–NO4A, NO1B–NO4B, V+, V−, and GND matches the DG409 footprint in the 16-pin DIP package - enabling direct replacement without layout changes, as stated in the Features section of the MAX399EPE+ datasheet.
What is the guaranteed on-resistance matching between channels for the MAX399EPE+?
The MAX399EPE+ guarantees ΔRON (difference between max and min on-resistance across all channels) to be less than 6Ω over the full operating temperature range (−40°C to +85°C). This is measured under standardized conditions (INO = 1mA, VCOM = ±3.5V, V+ = 5V, V− = −5V) and is a key specification distinguishing it from generic analog switches.
Does the MAX399EPE+ support single-supply operation?
Yes, the MAX399EPE+ operates from a single +3V to +15V supply. When using single supply, V− must be connected to GND. Performance parameters including RON, leakage, and switching speed are fully characterized down to +3V (e.g., RON = 425Ω max at +3V), making the MAX399EPE+ suitable for battery-powered systems where supply headroom is limited.
What is the maximum charge injection specification for the MAX399EPE+?
The MAX399EPE+ guarantees charge injection of less than 5pC across all operating conditions, including worst-case VCOM and temperature extremes. This value is tested and specified in the Electrical Characteristics table under "Charge Injection (Note 3)" and is critical for maintaining accuracy in sample-and-hold and switched-capacitor circuit applications using the MAX399EPE+.
