Product details
Overview
MAX314LEUE+ 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+ datasheet, MAX314LEUE+ pinout, MAX314LEUE+ application, or MAX314LEUE+ equivalent, key selection criteria include dual-/single-supply flexibility, guaranteed break-before-make timing (1–10 ns), +3V logic compatibility (VIH = 2.0V, VIL = 0.8V), and leakage performance of ±2.5nA at +85°C.
Technical Context
The MAX314LEUE+ implements CMOS-based transmission-gate architecture optimized for bidirectional analog conduction with symmetrical on-resistance across voltage rails. Its internal logic decodes independent IN1–IN4 inputs to control four discrete SPST switches - two NC (pins 3,6,11,14 mapped as NC1/NC4/NC3/NC2) and two NO (same pins repurposed as NO1/NO4/NO3/NO2 per truth table).
It eliminates power-supply sequencing constraints via integrated level-shifting circuitry, supporting arbitrary V+/V− ramp-up order without latch-up risk. Break-before-make timing is guaranteed only for the MAX314L variant (tD = 1–10 ns), distinguishing it from the MAX312L (NC-only) and MAX313L (NO-only) siblings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 10Ω max at ±15V dual supply - ensures minimal signal attenuation and gain error in precision instrumentation paths. |
| RON match between channels | 1.5Ω max - enables matched gain/phase response across multi-channel signal routing (e.g., stereo audio, differential ADC front-end). |
| Analog signal range | Rail-to-rail: V− to V+ - supports full dynamic range utilization in ±15V op-amp circuits or +12V data-acquisition systems. |
| Logic compatibility | +3V compatible: VIH = 2.0V, VIL = 0.8V - interfaces directly with 3.3V microcontrollers without level shifters. |
| Off-leakage current | ±2.5nA max at +85°C - preserves accuracy in high-impedance sample-and-hold or sensor multiplexing applications. |
| Turn-on/turn-off time | 275ns / 235ns max (dual supply) - supports >1MHz switching in automated test equipment (ATE) signal path control. |
| Crosstalk | >96dB at 20kHz - prevents inter-channel interference in multi-signal audio routing or telecom line cards. |
Pinout & Package
MAX314LEUE+ is housed in a 16-pin TSSOP package (U16-1, 4.4mm × 5.0mm, 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 | Independent TTL/CMOS-compatible digital control inputs - each drives one SPST switch. |
| 2, 7, 10, 15 | COM1, COM2, COM3, COM4 | Analog common terminals - bidirectional signal path junctions for all four switches. |
| 3, 6 | NO1, NO4 | Normally open analog terminals - conduct only when corresponding INx = logic high. |
| 11, 14 | NC3, NC2 | Normally closed analog terminals - conduct when corresponding INx = logic low. |
| 4 | V− | Negative analog supply input - connect to GND for single-supply operation (+4.5V to +36V). |
| 5 | GND | Ground reference - required for logic interface and internal biasing stability. |
| 12 | N.C. | No internal connection - must be left floating or tied to GND for mechanical stability. |
| 13 | V+ | Positive analog supply input - supplies both analog signal path and level-shifted logic interface. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - eliminates clipping in ±12V op-amp stages or +24V industrial I/O. |
| Guaranteed break-before-make | tD = 1–10 ns (MAX314L only) - prevents momentary short-circuit during channel switching in relay-replacement designs. |
| +3V logic compatibility | VIH = 2.0V, VIL = 0.8V - enables direct interfacing with 3.3V FPGAs, microcontrollers, and CPLDs without external translators. |
| Low charge injection | ±30pC max - minimizes voltage glitch in sample-and-hold circuits and precision DAC output switching. |
| Pin compatibility | Drop-in replacement for MAX314 and DG413 - allows legacy design upgrades without PCB rework. |

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; 16-pin narrow SO package (5.3mm width vs. TSSOP's 4.4mm). | Preferred for through-hole prototyping or legacy SO footprint compatibility. | Select MAX314LESE+ when board space permits wider SO layout or hand-soldering is required. |
| ADG413BRZ | Higher RON (35Ω typ), no guaranteed break-before-make, −40°C to +85°C rating. | Suitable for non-critical switching where timing integrity is not mandatory. | Choose ADG413BRZ only if cost sensitivity outweighs need for sub-10ns tD and 1.5Ω RON matching. |
Compared with MAX314LEUE+, MAX314LESE+ offers identical performance in a larger SO package for easier assembly, while ADG413BRZ trades guaranteed break-before-make and tighter RON matching for broader vendor availability - making MAX314LEUE+ optimal for timing-critical, high-precision analog routing.

FAQ
What is the operating temperature range for MAX314LEUE+?
The MAX314LEUE+ is rated for −40°C to +85°C operation, validated across its full electrical specification range including on-resistance, leakage, and switching times. This extended temperature grade makes MAX314LEUE+ suitable for industrial control cabinets, avionics bays, and outdoor test equipment where ambient conditions exceed commercial limits.
Does MAX314LEUE+ support single-supply operation?
Yes, MAX314LEUE+ supports single-supply operation from +4.5V to +36V by connecting V− to GND. In this mode, the analog signal range extends from 0V to V+, maintaining rail-to-rail capability. The device retains +3V logic compatibility and all key specs - though RON increases to 35Ω max (vs. 10Ω max in dual-supply mode).
How does the MAX314LEUE+ differ from MAX312LEUE+ and MAX313LEUE+?
MAX314LEUE+ integrates two normally closed (NC) and two normally open (NO) SPST switches in one package. In contrast, MAX312LEUE+ contains four NC switches, and MAX313LEUE+ contains four NO switches. Only MAX314LEUE+ guarantees break-before-make timing (tD = 1–10 ns), critical for preventing signal shorts during channel transitions.
Is MAX314LEUE+ pin-compatible with older MAX314 devices?
Yes, MAX314LEUE+ is pin-compatible with the legacy MAX314 series (e.g., MAX314CPE) and industry-standard DG413, allowing drop-in replacement without PCB changes. Key improvements include enhanced ESD tolerance, lower leakage, and elimination of power-supply sequencing requirements - all maintained within the same 16-pin TSSOP footprint.
What is the maximum analog signal voltage supported by MAX314LEUE+?
MAX314LEUE+ supports analog signals from V− to V+, with absolute maximum ratings of −44V to +44V on V+ and V−. When operated at ±15V supplies, the safe analog signal range is −15V to +15V; at +12V single supply, it is 0V to +12V. Exceeding V+ or V− clamps signals via internal diodes - limit forward current to ≤100mA continuous.
