Product details
Overview
MAX313LEUE+ from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO) analog switch IC designed for precision signal routing in industrial and test equipment. It features 10Ω max on-resistance, 1.5Ω max on-resistance matching between channels, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and +3V logic-compatible inputs (VIH = 2.0V, VIL = 0.8V). It operates across –40°C to +85°C and is housed in a 16-pin TSSOP package.
For engineers reviewing the MAX313LEUE+ datasheet, MAX313LEUE+ pinout, MAX313LEUE+ application, or MAX313LEUE+ equivalent, key selection considerations include rail-to-rail analog signal handling, low charge injection (±30pC), guaranteed RON flatness (≤4Ω), crosstalk >96dB at 20kHz, and compatibility with legacy DG411/DG412 footprints in high-reliability signal-path designs.
Technical Context
The MAX313LEUE+ implements four independent SPST NO switches using CMOS process technology, enabling bidirectional conduction with symmetric on-resistance behavior over full analog signal range (VCOM = V− to V+). Its logic interface accepts +3V-level signals regardless of supply configuration - no level-shifting required when powered from ±15V or +12V rails.
Each channel guarantees ≤10Ω on-resistance at ±10V signal swing and ≤1.5Ω matching between any two channels under identical conditions. Off-isolation exceeds –75dB at 1MHz, and dynamic performance includes 275ns max turn-on time (dual supply) and 425ns max turn-on time (single supply) into 300Ω/35pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally open (NO) - all four switches default open; logic high closes path. |
| On-Resistance (RON) | 10Ω max (dual supply, ±10V); ensures minimal signal attenuation and voltage drop in precision analog paths. |
| RON Matching | 1.5Ω max between channels - critical for matched gain/phase in multi-channel instrumentation and audio routing. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports wide-range industrial power architectures without external regulators. |
| Logic Compatibility | +3V compatible (VIH = 2.0V, VIL = 0.8V) - interfaces directly with microcontrollers, FPGAs, and ASICs without level shifters. |
| Leakage Current | ±2.5nA max at +85°C - preserves signal integrity in high-impedance sample-and-hold and sensor front-end circuits. |
| Crosstalk | >96dB at 20kHz - prevents audible or measurable interference between adjacent switched audio or data channels. |
Pinout & Package
Package: 16-pin TSSOP (U16-1), 4.4mm × 5.0mm body, 0.65mm pitch, exposed pad connected to V+ per datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic control inputs | Active-high enables corresponding NO switch; compatible with 3V CMOS logic regardless of analog supply voltage. |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Bidirectional signal path endpoints; support rail-to-rail input/output (V− to V+) with no polarity restriction. |
| NO1–NO4 (Pins 3, 6, 11, 14) | Normally open analog terminals | Signal connects to COM only when respective IN is high; zero DC bias requirement for open state. |
| V+ (Pin 13) | Positive analog supply | Accepts +4.5V to +36V (single) or +4.5V to +20V (dual); exposed pad must be tied to V+ for thermal and electrical stability. |
| V− (Pin 4) | Negative analog supply | Accepts –4.5V to –20V in dual mode; connect to GND for single-supply operation (0V to V+). |
| GND (Pin 5) | Ground reference | Logic and substrate reference; separate from analog return but internally tied - requires low-impedance PCB connection. |
| N.C. (Pin 12) | No internal connection | Not bonded; must remain unconnected to avoid parasitic coupling or mechanical stress on die. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping or distortion - essential for ±10V industrial sensor interfaces. |
| Guaranteed RON flatness | ≤2Ω max variation over full signal range - maintains consistent gain and THD in audio and measurement applications. |
| Break-before-make timing (MAX314L only) | Not applicable - MAX313LEUE+ is NO-only; no internal break-before-make circuitry present. |
| Power-supply sequencing freedom | No VL pin or strict V+/V−/GND ramp order required - eliminates need for external sequencing circuitry in complex power systems. |
| Low charge injection | ±30pC max - minimizes voltage glitch on sampled nodes in precision data-acquisition and hold circuits. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG412DN-E3 | Higher RON (60Ω typ), wider temp range (–40°C to +125°C), no exposed pad, SOIC-16 only | Lower bandwidth and higher distortion limit use in precision audio or high-speed data acquisition | Select DG412DN-E3 only if extended temperature rating is mandatory and 60Ω RON is acceptable in system budget. |
| MAX313CSE+ | Same architecture but commercial temp range (0°C to +70°C); otherwise identical electrical specs and pinout | Not qualified for extended industrial or avionics environments requiring –40°C startup or +85°C sustained operation | Choose MAX313CSE+ only for cost-sensitive, non-extended-temp consumer or lab-grade equipment. |
Compared with DG412DN-E3 and MAX313CSE+, the MAX313LEUE+ uniquely delivers 10Ω RON with –40°C to +85°C qualification in TSSOP - enabling compact, high-fidelity signal routing where thermal stability and low on-resistance are jointly required.

FAQ
What is the maximum analog signal voltage range supported by the MAX313LEUE+?
The MAX313LEUE+ supports rail-to-rail analog signals from V− to V+. With dual supplies of ±15V, this yields a full –15V to +15V range. In single-supply mode at +12V, it handles 0V to +12V. Absolute maximum ratings allow VCOM/VNO to extend 0.3V beyond rails, but operation within V− to V+ is guaranteed per datasheet specifications for the MAX313LEUE+.
Is the MAX313LEUE+ pin-compatible with the older MAX313 or DG412 devices?
Yes, the MAX313LEUE+ is pin-compatible with the MAX313 and DG412/DG413 families in 16-pin SO, TSSOP, and DIP packages. Pin functions match exactly: INx, COMx, NOx, V+, V−, GND, and N.C. are identically positioned. This allows drop-in replacement without PCB modification, provided the design accommodates the MAX313LEUE+'s improved performance and extended temperature range.
Does the MAX313LEUE+ require power-supply sequencing during startup?
No, the MAX313LEUE+ eliminates the VL pin and associated sequencing constraints of earlier MAX313 variants. It operates safely with any power-up order of V+, V−, and GND. However, absolute maximum ratings (e.g., V+ to V− ≤ +44V) must never be exceeded during power transitions. This simplifies system design and improves robustness in the MAX313LEUE+ compared to legacy analog switches.
What is the typical charge injection value for the MAX313LEUE+, and why does it matter?
The MAX313LEUE+ specifies ±30pC maximum charge injection. This parameter quantifies the transient voltage glitch injected onto the COM node when the switch toggles. In sample-and-hold or high-impedance sensor interfaces, excessive charge injection causes settling errors and measurement inaccuracy. The low ±30pC value of the MAX313LEUE+ ensures fast settling and high DC accuracy - critical for 16-bit+ data acquisition systems.
Can the MAX313LEUE+ operate from a single +5V supply?
No, the MAX313LEUE+ minimum single-supply voltage is +4.5V, but its RON degrades significantly below +12V. At +5V, RON rises to ~35Ω (vs. 10Ω at ±15V), and leakage increases. For reliable low-RON performance, use ≥+12V single supply or ±12V dual supply. The MAX313LEUE+ is not optimized for 3.3V or 5V logic-system integration - it targets industrial and instrumentation applications with higher supply headroom.
