Product details
Overview
MAX313LCUE+T from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO) analog switch IC designed for precision signal routing in ±15V or +12V systems. It delivers 10Ω max on-resistance, 1.5Ω max on-resistance matching between channels, and +3V logic-compatible inputs (VIH = 2.0V, VIL = 0.8V), enabling direct interface with low-voltage microcontrollers in audio routing and data-acquisition front-ends.
For engineers reviewing the MAX313LCUE+T datasheet, MAX313LCUE+T pinout, MAX313LCUE+T application, or MAX313LCUE+T equivalent, key selection criteria include guaranteed RON flatness (≤4Ω over signal range), rail-to-rail analog signal handling (±15V dual or +4.5V to +36V single supply), crosstalk >96dB at 20kHz, and leakage <2.5nA at +85°C - all critical for low-distortion, high-isolation switching in test equipment and avionics.
Technical Context
The MAX313LCUE+T implements four independent CMOS SPST NO switches with matched channel characteristics, supporting bidirectional signal conduction and operating across dual supplies (±4.5V to ±20V) or single supplies (+4.5V to +36V). Its architecture eliminates the need for power-supply sequencing, unlike legacy MAX313, by removing the VL pin and integrating robust ESD protection.
Each switch features guaranteed RON matching ≤1.5Ω and RON flatness ≤4Ω over the full analog signal range, ensuring minimal THD in audio paths. Charge injection is limited to ±30pC, and off-isolation exceeds −75dB at 1MHz, making it suitable for precision sample-and-hold and xDSL modem line switching where signal integrity is paramount.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max at ±15V dual supply - ensures minimal voltage drop and power loss in signal paths up to ±10V. |
| RON Matching | 1.5Ω max between channels - preserves amplitude balance across multi-channel audio or sensor multiplexing. |
| Logic Compatibility | +3V compatible (VIH = 2.0V, VIL = 0.8V) - interfaces directly with 3.3V GPIO without level-shifting. |
| Analog Signal Range | Rail-to-rail: V− to V+ - supports full-swing signals in ±15V or +12V systems without clipping. |
| Off-Leakage Current | ±2.5nA max at +85°C - prevents DC error accumulation in high-impedance sample-and-hold circuits. |
| Crosstalk | >96dB at 20kHz - suppresses inter-channel interference in multi-signal routing applications like PBX. |
| Turn-On/Off Time | 275ns / 235ns max (dual supply) - enables fast switching in automated test equipment scan sequences. |
Pinout & Package
MAX313LCUE+T is housed in a 16-pin TSSOP package (package code U16-1), 4.4mm × 5.0mm body, 0.65mm pitch, with exposed pad connected to V+ for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic turns corresponding NO switch ON. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path entry/exit points for each switch. |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog outputs - connect to COM only when IN = logic high. |
| 4 | V− | Negative analog supply input; tie to GND for single-supply operation (+4.5V to +36V). |
| 5 | GND | Ground reference for logic and substrate; must be low-impedance for noise immunity. |
| 12 | N.C. | No internal connection - leave unconnected; not usable as thermal pad or ground. |
| 13 | V+ | Positive analog supply input - powers analog core and defines upper rail of signal range. |
Key Features
| Feature | Design Value |
|---|---|
| +3V logic compatibility | Eliminates level shifters when interfacing with 3.3V microcontrollers or FPGAs in embedded systems. |
| Guaranteed RON flatness ≤4Ω | Maintains consistent gain and low THD across full analog input range (±10V), critical for audio fidelity. |
| Rail-to-rail signal handling | Supports full-swing signals from V− to V+ without distortion, enabling use in ±15V industrial instrumentation. |
| Power-supply sequencing freedom | Removes VL pin and latch-up risk - allows arbitrary V+/V−/GND power-up order in complex power systems. |
| Low charge injection (±30pC) | Minimizes voltage glitch on sampled nodes, improving accuracy in precision data-acquisition hold capacitors. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX313LESE | Same functionality and pinout, but −40°C to +85°C extended temperature grade and SO package (wider 10.3mm body vs. TSSOP's 5.0mm). | Suitable for industrial motor drives or outdoor telecom gear requiring wider thermal margin and through-hole assembly. | Select MAX313LESE when board space permits larger SO footprint and ambient operating temperature exceeds +70°C. |
| ADG1414BRUZ | Quad SPST NO switch with 1.8Ω typical RON, but requires 5V logic and lacks guaranteed RON matching spec; 16-TSSOP pinout identical. | Better for ultra-low-RON needs in battery-powered portable instruments, but not drop-in for +3V logic systems. | Choose ADG1414BRUZ only if system uses 5V logic and prioritizes sub-2Ω RON over guaranteed matching and leakage specs. |
Compared with MAX313LESE, the MAX313LCUE+T offers tighter thermal qualification (0°C to +70°C) and smaller TSSOP footprint, while ADG1414BRUZ trades guaranteed matching and +3V logic compatibility for lower RON - making MAX313LCUE+T optimal for space-constrained, 3.3V-controlled test and audio systems.

FAQ
What is the maximum supply voltage rating for MAX313LCUE+T?
The MAX313LCUE+T supports dual supplies from ±4.5V to ±20V and single supplies from +4.5V to +36V. Absolute maximum ratings specify V+ up to +44V and V− down to −44V, but operation beyond ±20V or +36V violates specifications and risks permanent damage. For reliable long-term use, stay within the recommended supply ranges listed in the Electrical Characteristics table.
Does MAX313LCUE+T require power-supply sequencing?
No, MAX313LCUE+T does not require power-supply sequencing. Unlike earlier MAX313 devices, it eliminates the VL pin and integrates latch-up immunity, allowing arbitrary power-up order of V+, V−, and GND. This simplifies power design in systems with multiple rails and avoids the need for external protection diodes.
Can MAX313LCUE+T be used in single-supply +5V systems?
Yes, MAX313LCUE+T operates from +4.5V to +36V single supply. At +5V, it maintains +3V logic compatibility (VIH = 2.0V), but RON increases to ~35Ω (vs. 10Ω at ±15V), and analog signal range is limited to 0V to +5V. Use +12V or higher for optimal RON and rail-to-rail performance.
What is the function of Pin 12 (N.C.) on MAX313LCUE+T?
Pin 12 on MAX313LCUE+T is a no-connect (N.C.) terminal with no internal connection. It must remain unconnected on the PCB - neither grounded nor tied to any voltage. Using it as a thermal pad or ground point may cause electrical malfunction or reliability issues.
How does MAX313LCUE+T differ from MAX313CUE?
MAX313LCUE+T is the enhanced "L" version: it guarantees RON matching (≤1.5Ω), RON flatness (≤4Ω), and improved leakage specs (<2.5nA at +85°C), whereas MAX313CUE lacks these guarantees. The "L" version also removes the VL pin, enabling sequencing-free operation - a key reliability upgrade for new designs.
