Product details
Overview
MAX314LCUE+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 (1.5Ω max) and rail-to-rail signal handling are critical.
For engineers reviewing the MAX314LCUE+T datasheet, MAX314LCUE+T pinout, MAX314LCUE+T application, or MAX314LCUE+T equivalent, key selection criteria include guaranteed RON flatness (2Ω max), break-before-make timing (1–10ns), crosstalk >96dB at 20kHz, and TSSOP-16 package compatibility with industrial temperature range (0°C to +70°C).
Technical Context
The MAX314LCUE+T implements four independent CMOS SPST switches in one die, with dedicated NC and NO terminals per channel-switches 1 and 4 are NC, switches 2 and 3 are NO. Its architecture supports bidirectional conduction, rail-to-rail analog signal ranges (VCOM, VNC, VNO from V− to V+), and operates without power-supply sequencing constraints.
It delivers low charge injection (±30pC), minimal off-leakage (±2.5nA at +85°C), and stable dynamic performance: tON ≤ 275ns and tOFF ≤ 235ns (dual-supply, ±15V), with guaranteed break-before-make delay for channel switching integrity in multiplexer configurations.
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 accurate gain/phase matching in multi-channel instrumentation and audio summing. |
| Analog supply range | ±4.5V to ±20V dual or +4.5V to +36V single - supports wide-range industrial and telecom signal conditioning. |
| Logic input thresholds | VIH = 2.0V, VIL = 0.8V - compatible with standard +3V CMOS microcontrollers without level-shifting. |
| Crosstalk | >96dB at 20kHz - prevents audible inter-channel coupling in stereo audio routing applications. |
| Break-before-make delay | 1–10ns - avoids momentary short-circuit during channel switching in multiplexed data acquisition. |
| Off-leakage current | ±2.5nA at +85°C - preserves accuracy in high-impedance sample-and-hold and sensor front-end circuits. |
Pinout & Package
MAX314LCUE+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 enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic control inputs | Active-high digital signals controlling switch state; compatible with +3V logic families. |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Bidirectional signal path connection points shared between NC and NO paths per channel. |
| NC1, NC2, NC3, NC4 (Pins 3, 6, 11, 14) | Normally closed analog terminals | Connected to COM when IN = 0; pins 3 & 6 are NC for switches 1 & 4; pins 11 & 14 are NC for switches 2 & 3. |
| NO1, NO2, NO3, NO4 (Pins 3, 6, 11, 14) | Normally open analog terminals | Connected to COM when IN = 1; pins 3 & 6 are NO for switches 2 & 3; pins 11 & 14 are NO for switches 1 & 4. |
| V+ (Pin 13) | Positive analog supply | Accepts +4.5V to +36V (single) or +4.5V to +20V (dual); powers internal circuitry and defines upper analog rail. |
| V− (Pin 4) | Negative analog supply | Accepts −4.5V to −20V (dual); connect to GND for single-supply operation. |
| GND (Pin 5) | Ground reference | Logic and substrate reference; must be low-impedance for noise-sensitive analog routing. |
| N.C. (Pin 12) | No connection | Internally unconnected; leave floating or tie to GND for mechanical stability only. |
Key Features
| Feature | Design Value |
|---|---|
| +3V logic compatibility | VIH = 2.0V / VIL = 0.8V enables direct interface with low-voltage microcontrollers and FPGAs without level shifters. |
| Guaranteed RON flatness | 2Ω max over full analog signal range ensures consistent gain and THD across varying input amplitudes. |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - essential for ±10V industrial I/O and audio line-level routing. |
| Pin compatibility | Drop-in replacement for MAX314 and industry-standard DG413, simplifying legacy design upgrades. |
| Power-supply sequencing freedom | No VL pin or strict V+/V−/GND power-up order required - reduces system-level BOM and layout complexity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX314CUE+ | Legacy non-L version; higher RON (15Ω max), no guaranteed RON flatness, requires VL bias pin and strict power sequencing. | Lacks break-before-make timing spec and +3V logic compatibility; unsuitable for low-voltage MCU interfaces. | Select MAX314LCUE+T for new designs requiring simplified power architecture and tighter analog matching. |
| DG413DN-E3 | 12Ω RON, 2.5Ω RON match, no break-before-make guarantee, VIH = 2.4V minimum - less tolerant of marginal logic drive. | Higher THD and lower off-isolation limit use in high-fidelity audio; not qualified for extended temperature range. | Choose MAX314LCUE+T when rail-to-rail signal swing, low leakage, and industrial temp grade are mandatory. |
Compared with MAX314CUE+ and DG413DN-E3, the MAX314LCUE+T provides superior RON consistency, eliminates power-sequencing overhead, and delivers verified break-before-make behavior - making it the preferred choice for precision, safety-critical, and low-voltage embedded analog routing.

FAQ
What is the operating temperature range for MAX314LCUE+T?
The MAX314LCUE+T is specified for operation from 0°C to +70°C. This commercial-grade temperature range is validated per the device's ordering information and electrical characteristics tables, and applies to all parametric performance metrics including RON, leakage, and switching times. The 'C' suffix in the part number explicitly denotes this temperature grade.
Does MAX314LCUE+T support single-supply operation?
Yes, MAX314LCUE+T supports single-supply operation from +4.5V to +36V. In this mode, V− (pin 4) must be connected to GND, and analog signals may swing from 0V to V+. The datasheet confirms rail-to-rail signal handling and specifies RON = 35Ω max and leakage ≤ ±2.5nA under single-supply conditions at full temperature range.
How is the NC/NO configuration arranged in MAX314LCUE+T?
In MAX314LCUE+T, switches 1 and 4 are normally closed (NC), while switches 2 and 3 are normally open (NO). This is implemented via pin mapping: pins 3 and 6 serve as NC1/NC4 and NO2/NO3 respectively, and pins 11 and 14 serve as NC3/NC2 and NO1/NO4 - confirmed in the Pin Descriptions table and MAX314L truth diagram in the datasheet.
Is MAX314LCUE+T pin-compatible with older MAX314 variants?
Yes, MAX314LCUE+T is pin-compatible with MAX314CUE+ and MAX314EUE+ in the 16-pin TSSOP package. All share identical pin functions, spacing, and footprint - enabling drop-in replacement without PCB modification. However, the 'L' version removes the VL pin requirement and improves RON specs, so validation of timing and leakage in the target application is recommended.
What is the maximum analog signal voltage range supported by MAX314LCUE+T?
MAX314LCUE+T supports analog signals from V− to V+, with absolute maximum ratings of V+ = −0.3V to +44V and V− = +0.3V to −44V. Under recommended operating conditions, it handles ±10V signals with guaranteed RON ≤ 10Ω and leakage ≤ ±2.5nA at +85°C - making it suitable for industrial ±10V I/O and audio line-level applications.
