Product details
Overview
MAX314LEUE+T from Maxim Integrated is a quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, designed for precision signal routing in ±4.5V to ±20V or +4.5V to +36V systems. It delivers 10Ω max on-resistance, 1.5Ω max RON matching between channels, and rail-to-rail signal handling - enabling low-distortion audio routing and high-fidelity data-acquisition front-ends.
For engineers reviewing the MAX314LEUE+T datasheet, MAX314LEUE+T pinout, MAX314LEUE+T application, or MAX314LEUE+T equivalent, key selection criteria include guaranteed RON flatness (≤4Ω), −96dB crosstalk at 20kHz, +3V logic compatibility (VIH = 2.0V, VIL = 0.8V), and −40°C to +85°C industrial temperature operation in 16-pin TSSOP.
Technical Context
The MAX314LEUE+T implements four independent CMOS SPST switches with mixed NC/NO topology: IN1/COM1/NC1 and IN4/COM4/NO4 form one pair; IN2/COM2/NC2 and IN3/COM3/NO3 form the second. Its dual-supply architecture supports symmetric (±4.5V to ±20V) or single-supply (+4.5V to +36V) operation without power sequencing constraints.
Each channel features matched on-resistance across temperature (15Ω max over −40°C to +85°C), low charge injection (±30pC), and sub-2.5nA off-leakage at +85°C. Break-before-make timing is guaranteed at 1ns to 10ns (typical 5ns) for controlled switching transitions in multiplexer configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 10Ω max - ensures minimal signal attenuation and gain error in precision instrumentation paths |
| RON match between channels | 1.5Ω max - enables accurate channel-to-channel signal balancing in differential or multi-path systems |
| Supply range | +4.5V to +36V single or ±4.5V to ±20V dual - supports wide-range industrial and avionics power architectures |
| Crosstalk | >96dB at 20kHz - prevents audible interference in stereo audio routing and adjacent-channel coupling in data acquisition |
| Logic compatibility | +3V compatible (VIH = 2.0V, VIL = 0.8V) - interfaces directly with 3.3V microcontrollers and FPGAs without level shifters |
| Operating temperature | −40°C to +85°C - qualified for extended industrial and avionics environments without derating |
| Turn-on/turn-off time | 115ns–275ns (tON), 100ns–235ns (tOFF) - supports fast-switching applications up to ~3MHz signal bandwidth |
Pinout & Package
MAX314LEUE+T is housed in a 16-pin TSSOP (U16-1 package), 4.4mm × 5.0mm body, 0.65mm pitch, with exposed pad connected to V+. Pin functions are electrically identical across MAX312L/MAX313L/MAX314L families but differ in NC/NO assignment per channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1, IN2, IN3, IN4 | Digital control inputs - active-high logic drives corresponding switch state (NC or NO) |
| 2, 7, 10, 15 | COM1, COM2, COM3, COM4 | Analog common terminals - bidirectional signal path shared by NC and NO pins per channel |
| 3, 6 | NO1, NO4 | Normally open analog terminals - conduct only when respective INx = logic high |
| 11, 14 | NC3, NC2 | Normally closed analog terminals - conduct when respective INx = logic low |
| 4 | V− | Negative supply rail - connect to GND for single-supply operation |
| 5 | GND | Ground reference - required for logic and analog return paths |
| 12 | N.C. | No internal connection - must be left floating or tied to GND per layout best practice |
| 13 | V+ | Positive supply rail - powers analog core and logic interface; exposed pad must connect to V+ |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - preserves full dynamic range in ±15V op-amp circuits and audio line drivers |
| Guaranteed RON flatness | ≤2Ω max over full signal range - minimizes harmonic distortion in audio and measurement applications |
| Low leakage current | ±2.5nA max at +85°C - maintains accuracy in high-impedance sample-and-hold and sensor front-ends |
| Break-before-make timing | 1ns to 10ns (guaranteed) - prevents momentary short-circuits during channel switching in multiplexed systems |
| Pin compatibility | Drop-in replacement for MAX314 and DG413 - enables legacy design upgrades without PCB revision |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX314LESE | Same electrical specs; packaged in 16-pin narrow SO (S16-8) instead of TSSOP | SO package offers easier hand-soldering and higher creepage; lower thermal performance than TSSOP with EP | Select MAX314LESE for prototyping or low-volume production where reflow capability is limited |
| ADG413BRUZ | Quad SPST, +3V logic-compatible, but RON = 35Ω typical (vs. 10Ω max), no guaranteed RON match spec | Higher on-resistance limits use in precision audio or low-voltage sensor paths; suitable for general-purpose digital I/O switching | Choose ADG413BRUZ only if footprint compatibility is critical and RON >25Ω is acceptable |
Compared with MAX314LEUE+T, MAX314LESE provides identical functionality in a through-hole–friendly SO package but sacrifices thermal efficiency, while ADG413BRUZ trades on-resistance performance and matching guarantees for broader availability - making MAX314LEUE+T optimal for high-fidelity, thermally constrained, or metrology-grade designs.

FAQ
What is the maximum supply voltage rating for MAX314LEUE+T?
The MAX314LEUE+T supports absolute maximum supply ratings of V+ = +44V and V− = −44V, with recommended operating ranges of +4.5V to +36V (single supply) or ±4.5V to ±20V (dual supply). Exceeding these limits risks permanent damage, and operation above ±20V requires verification of internal clamp diode behavior under signal overvoltage conditions.
Does MAX314LEUE+T require power-supply sequencing?
No, MAX314LEUE+T eliminates power-supply sequencing requirements present in earlier MAX314 devices. Its architecture permits arbitrary power-up order of V+, V−, and GND, removing the need for external protection diodes or complex power-rail controllers - a key reliability enhancement for industrial and avionics systems.
How does the NC/NO configuration work in MAX314LEUE+T?
The MAX314LEUE+T integrates two NC switches (channels 1 and 4: IN1/COM1/NC1 and IN4/COM4/NC4) and two NO switches (channels 2 and 3: IN2/COM2/NO2 and IN3/COM3/NO3). When INx = logic low, NC channels conduct and NO channels disconnect; when INx = logic high, NC channels disconnect and NO channels conduct - enabling flexible signal path control per channel.
Can MAX314LEUE+T operate from a single +5V supply?
No - the minimum single-supply voltage for MAX314LEUE+T is +4.5V, and operation at +5V is not characterized or guaranteed. At +5V, RON increases significantly (≥35Ω typical), leakage rises, and logic thresholds become marginal. For +5V systems, consider the MAX4617 or similar 5V-optimized analog switches instead of MAX314LEUE+T.
Is the exposed pad on MAX314LEUE+T electrically connected?
Yes - the exposed pad on MAX314LEUE+T is internally connected to V+ and must be soldered to a V+ copper pour for thermal performance and EMI suppression. Leaving it unconnected degrades power dissipation capability and may cause instability under high-current switching conditions. Thermal resistance θJA is specified assuming proper EP soldering per Maxim's land pattern U16-1.
