Product details
Overview
MAX399CSE+T 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 (typ. 60Ω), <6Ω channel-to-channel RON matching, and <5pC charge injection - enabling high-fidelity sample-and-hold and battery-operated data-acquisition circuits.
For engineers reviewing the MAX399CSE+T datasheet, MAX399CSE+T pinout, MAX399CSE+T application, or MAX399CSE+T equivalent, this page provides verified electrical specs, package-validated pin functions, real-world use cases in military radios and PBX systems, and two confirmed alternative parts with documented functional and interface differences.
Technical Context
The MAX399CSE+T implements a dual independent 4:1 analog switch architecture with TTL/CMOS-compatible digital control (A0, A1, EN) and rail-to-rail analog signal handling across ±3V to ±8V bipolar or +3V to +15V single supplies. Its silicon-gate CMOS process ensures ESD protection >2000V and guarantees flat on-resistance (<11Ω variation) over the full analog range.
Each 4-channel block features separate COMA/COMB outputs and shared address inputs, supporting simultaneous or independent switching. The device maintains sub-250ns transition time and <2.5nA NO off-leakage at +85°C - critical for low-drift automatic test equipment and guidance system front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual 4-channel analog multiplexer - two independent 4:1 switches sharing address lines |
| On-resistance (RON) | 60Ω typ. at V± = ±5V - enables <1 LSB error in 12-bit ADC front-ends with ≤1kΩ source impedance |
| RON matching | <6Ω max between channels - preserves gain/phase balance in differential signal paths |
| Charge injection | <5pC max - limits voltage glitch to <5mV on 1nF hold capacitors in sample-and-hold stages |
| Analog signal range | ±4.5V with ±5V supplies - supports full-rail operation without clipping in ±5V systems |
| Off-leakage current | <2.5nA at +85°C on NO/COM - ensures <1µV/h drift in high-impedance sensor interfaces |
| Supply range | +3V to +15V single or ±3V to ±8V bipolar - compatible with legacy industrial and modern low-power designs |
Pinout & Package
MAX399CSE+T is supplied in a 16-pin narrow SOIC (SOIC-N) package (package code S16-1), with lead pitch 0.050", body width 0.150", and exposed pad not present (QFN variant uses EP; SOIC does not).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 | Binary address inputs selecting active channel (00–11) per 4-channel bank |
| 2 | EN | Active-high enable - disables all switches when low, preventing signal contention |
| 3 | V− | Negative supply rail - required for bipolar operation; tied to GND for single-supply mode |
| 4–7 | NO1A–NO4A | Analog inputs for first 4-channel bank - bidirectional, rail-to-rail capable |
| 8, 9 | COMA, COMB | Common analog I/O terminals - COMA serves bank A (NO1A–NO4A), COMB serves bank B (NO1B–NO4B) |
| 10–13 | NO1B–NO4B | Analog inputs for second 4-channel bank - electrically isolated from bank A |
| 14 | V+ | Positive supply rail - supports up to +15V; powers internal logic and switch driver circuitry |
| 15 | GND | Ground reference - return path for logic inputs and substrate bias |
Key Features
| Feature | Design Value |
|---|---|
| PIN compatibility with DG409/DG509A | Drop-in replacement in existing layouts using industry-standard 16-pin SOIC footprint |
| Guaranteed RON flatness | <11Ω variation across ±4.5V signal range - eliminates gain nonlinearity in precision instrumentation |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - enables direct interfacing with op-amps and ADCs without level-shifting |
| Low power consumption | <300µW typical - extends battery life in portable test gear and handheld radios |
| TTL/CMOS logic compatibility | VIH = 2.4V, VIL = 0.8V - interoperates with 3.3V and 5V microcontrollers without level translators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG409BRZ | Higher RON (100Ω typ.), no guaranteed RON matching, 16-pin SOIC package | Lacks <6Ω matching and <5pC charge injection - unsuitable for precision sample-and-hold | Acceptable for general-purpose audio routing where leakage and matching are less critical |
| TS5A23157DGSR | Single-supply only (+1.8V to +5.5V), lower RON (0.9Ω), but only dual SPDT (not dual 4:1) | No bipolar support or multi-channel addressing - cannot replace MAX399's dual 4:1 topology | Only viable for low-voltage, space-constrained designs requiring ultra-low RON, not functional equivalence |
Compared with ADG409BRZ and TS5A23157DGSR, the MAX399CSE+T uniquely combines dual 4:1 topology, guaranteed RON matching, bipolar supply support, and <5pC charge injection - making it irreplaceable in precision, wide-temperature, or military-grade signal routing.

FAQ
What is the maximum analog signal range supported by MAX399CSE+T?
The MAX399CSE+T supports an analog signal range of ±4.5V when operated with ±5V supplies, and rail-to-rail operation from V− to V+ across its full specified supply range (+3V to +15V single or ±3V to ±8V bipolar). This allows direct interfacing with op-amps and ADCs without external level-shifting circuitry, preserving signal integrity in precision measurement paths.
Is MAX399CSE+T pin-compatible with the DG409 analog multiplexer?
Yes, MAX399CSE+T is explicitly pin-compatible with the industry-standard DG409 and DG509A devices, as confirmed in the datasheet's Features section and Pin Configurations. This allows drop-in replacement in existing 16-pin SOIC layouts without PCB modifications - provided supply and signal-level requirements align with MAX399CSE+T's specifications.
What is the guaranteed on-resistance matching between channels for MAX399CSE+T?
The MAX399CSE+T guarantees on-resistance matching of less than 6Ω between any two channels within the same 4-channel bank, as stated in the datasheet's Features and Electrical Characteristics tables. This tight matching ensures consistent gain and phase response across switched signal paths - critical for differential measurements and multi-channel data acquisition.
Does MAX399CSE+T support single-supply operation?
Yes, MAX399CSE+T supports single-supply operation from +3V to +15V. In this mode, V− must be connected to GND. The device maintains rail-to-rail analog signal handling and retains TTL/CMOS logic compatibility, making it suitable for battery-powered instruments and portable communication equipment where dual supplies are impractical.
What is the maximum charge injection specification for MAX399CSE+T?
The MAX399CSE+T guarantees charge injection of less than 5pC, as specified in the datasheet's Features and Electrical Characteristics sections. This low value minimizes voltage glitches on hold capacitors in sample-and-hold circuits - for example, inducing less than 5mV error on a 1nF capacitor - directly supporting high-resolution (≥12-bit) data acquisition systems.
