Product details
Overview
MAX314LESE+T from Maxim Integrated is a quad, single-pole/single-throw (SPST) analog switch with two normally closed (NC) and two normally open (NO) channels, 10Ω max on-resistance, ±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 enables precision signal routing in high-fidelity audio and test equipment where low RON matching and rail-to-rail signal handling are critical.
For engineers reviewing the MAX314LESE+T datasheet, MAX314LESE+T pinout, MAX314LESE+T application, or MAX314LESE+T equivalent, key selection criteria include guaranteed 1.5Ω RON match between channels, break-before-make timing (1–10ns), crosstalk >96dB at 20kHz, and operation across –40°C to +85°C in 16-pin narrow SO package.
Technical Context
The MAX314LESE+T implements four independent CMOS SPST switches in one die, with dedicated NC and NO terminals per channel-two configured as NC, two as NO-enabling mixed-signal path selection without external reconfiguration. Its architecture supports bidirectional conduction, rail-to-rail analog signal handling (VCOM from V– to V+), and latch-up immunity via power-sequencing-free design.
It delivers stable performance across supply ranges: dual ±4.5V to ±20V or single +4.5V to +36V, with leakage currents limited to ±2.5nA at +85°C and charge injection of ±30pC. Dynamic specs include tON ≤ 275ns and tOFF ≤ 235ns (dual-supply, ±15V), and guaranteed break-before-make delay of 1–10ns for channel switching coordination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Match Between Channels | 1.5Ω max - enables matched gain/phase response across multiple switched channels |
| Analog Signal Range | V– to V+ - supports true rail-to-rail AC/DC signal switching without clipping |
| Logic Compatibility | +3V logic (VIH = 2.0V, VIL = 0.8V) - interfaces directly with 3.3V microcontrollers and FPGAs |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - accommodates industrial, test, and avionics power architectures |
| Crosstalk | >96dB at 20kHz - prevents audible interference in multi-channel audio routing |
| Off-Leakage Current | ±2.5nA at +85°C - preserves accuracy in high-impedance sample-and-hold and sensor front-ends |
Pinout & Package
MAX314LESE+T is housed in a 16-pin narrow SO (Small Outline) package with standard 1.27mm pitch, JEDEC MS-012AC compliant, and rated for –40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1, IN2, IN3, IN4 | Digital control inputs; active-high logic drives channel state (NC/NO) |
| 2, 7, 10, 15 | COM1, COM2, COM3, COM4 | Analog common terminals - bidirectional signal path entry/exit points |
| 3, 6 | NO1, NO4 | Normally open analog outputs - conduct only when corresponding IN is high |
| 11, 14 | NC3, NC2 | Normally closed analog outputs - conduct when corresponding IN is low |
| 4 | V− | Negative analog supply - connect to GND for single-supply use |
| 5 | GND | Ground reference for logic and analog sections |
| 12 | N.C. | No internal connection - leave unconnected |
| 13 | V+ | Positive analog supply - powers analog switch core and level-shifting circuitry |
Key Features
| Feature | Design Value |

Applications
| Audio Signal Routing | Test Equipment Multiplexing |
|---|---|
Use Scenario: Switching line-level stereo signals between multiple amplifiers, ADCs, or DACs in pro-audio mixing consoles. IC Role / Device Role / Timing Role: Quad SPST analog switch providing isolated, low-distortion signal paths with matched RON to preserve channel balance. Use Value: THD < –80dB across 20Hz–20kHz enables transparent audio switching without coloration or crosstalk-induced imaging artifacts. |
Use Scenario: Routing DUT signals to multiple measurement instruments (oscilloscope, spectrum analyzer, DMM) in automated test systems. IC Role / Device Role / Timing Role: Precision analog multiplexer with break-before-make timing ensuring no signal shorting during instrument reconfiguration. Use Value: 10Ω RON and <1.5Ω channel matching minimize gain error and offset drift across calibrated test paths. |
| PBX/PABX Line Interface | Avionics Signal Conditioning |
Use Scenario: Selecting between primary and backup voice/data lines in telecom central office switching hardware. IC Role / Device Role / Timing Role: Dual-mode (NC/NO) analog switch enabling hot-swappable line redundancy with automatic fallback. Use Value: Guaranteed RON flatness (≤2Ω over ±10V) ensures consistent impedance matching across line cards and minimizes echo return loss. |
Use Scenario: Isolating and routing sensor outputs (e.g., temperature, pressure) to flight control computers in harsh-environment aircraft subsystems. IC Role / Device Role / Timing Role: High-reliability analog switch operating from –40°C to +85°C with low leakage and ESD-hardened I/O. Use Value: ±2.5nA leakage at +85°C prevents DC offset accumulation in high-Z transducer conditioning circuits over extended mission durations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX314CSE+ | 0°C to +70°C temp range; otherwise identical electrical specs and pinout | Suitable only for commercial-grade systems without extended temperature requirements | Select MAX314CSE+ for cost-sensitive, non-industrial applications where ambient temperature stays within 0–70°C |
| ADG441BRZ | Quad SPST, +3V logic compatible, but RON = 40Ω (typ), no guaranteed RON match, and no break-before-make spec | Better suited for general-purpose switching where precision matching and timing are not critical | Choose ADG441BRZ only when lower cost outweighs need for sub-2Ω RON matching and coordinated switching |
Compared with MAX314CSE+ and ADG441BRZ, the MAX314LESE+T uniquely combines extended temperature rating (–40°C to +85°C), guaranteed 1.5Ω RON match, and documented break-before-make timing-making it the sole option for industrial test gear and avionics requiring traceable parametric consistency across environmental stress.

FAQ
What is the maximum on-resistance specification for MAX314LESE+T across temperature?
The MAX314LESE+T guarantees a maximum on-resistance (RON) of 15Ω over its full operating temperature range of –40°C to +85°C, measured at ICOM = 10mA and VNO/VNC = ±10V under dual-supply conditions. At +25°C, typical RON is 10Ω, confirming headroom for worst-case thermal derating in precision analog designs.
Does MAX314LESE+T support single-supply operation, and what is the minimum voltage?
Yes, MAX314LESE+T supports single-supply operation from +4.5V to +36V. The minimum valid supply is +4.5V - below this, RON, leakage, and logic thresholds are not guaranteed. At +12V single supply, RON remains ≤35Ω over temperature, and VIH/VIL remain at 2.0V/0.8V, preserving interface compatibility with 3.3V logic.
How does the two-NC/two-NO configuration of MAX314LESE+T differ from MAX312LESE+T or MAX313LESE+T?
Unlike MAX312LESE+T (quad NC) or MAX313LESE+T (quad NO), the MAX314LESE+T integrates two NC and two NO switches in one 16-pin SO package. This hybrid topology allows concurrent use of fail-safe (NC) and active-control (NO) paths - for example, maintaining default signal continuity while selectively enabling alternate routes - without requiring multiple devices or board space.
Is MAX314LESE+T pin-compatible with legacy MAX314 versions?
Yes, MAX314LESE+T is pin-compatible with MAX314CSE+, MAX314ESE+, and MAX314EPE+ in the same 16-pin narrow SO package. All share identical pin functions, electrical behavior, and footprint - the "L" suffix denotes improved latch-up immunity and relaxed power-sequencing requirements, with no layout or firmware changes needed for drop-in replacement.
What is the guaranteed break-before-make timing for MAX314LESE+T, and why is it important?
The MAX314LESE+T guarantees a break-before-make time delay (tD) of 1–10ns under RL = 300Ω and CL = 35pF conditions. This ensures that one switch opens before the other closes during channel reconfiguration - preventing transient shorts in multiplexer, relay-replacement, or redundant signal-path applications where even nanosecond overlap could cause system fault or measurement corruption.
