Product details
Overview
MAX313LCUE+ 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 test equipment and audio routing applications.
For engineers reviewing the MAX313LCUE+ datasheet, MAX313LCUE+ pinout, MAX313LCUE+ application, or MAX313LCUE+ equivalent, this device is selected for high-channel-count, rail-to-rail analog switching where low distortion, tight RON matching, and dual-supply flexibility are critical - especially in PBX systems, data-acquisition front-ends, and avionics signal conditioning.
Technical Context
The MAX313LCUE+ implements four independent NO SPST switches using CMOS process technology, supporting both single-supply (+4.5V to +36V) and dual-supply (±4.5V to ±20V) operation. Its architecture guarantees rail-to-rail analog signal handling and eliminates power-supply sequencing requirements - unlike legacy MAX313 variants - by removing the VL pin and integrating robust ESD protection.
Each channel features matched on-resistance (ΔRON ≤ 1.5Ω), flat on-resistance over signal range (RFLAT(ON) ≤ 2Ω), and ultra-low off-leakage (±2.5nA at +85°C). Crosstalk exceeds 96dB at 20kHz, and charge injection is limited to ±30pC, making it suitable for sample-and-hold and precision instrumentation circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally open (NO) configuration - all four channels open when logic input is low, closed when high. |
| On-Resistance (RON) | 10Ω maximum at ±15V supplies - ensures minimal signal attenuation and voltage drop in 50Ω–10kΩ signal paths. |
| RON Matching | 1.5Ω maximum difference between any two channels - preserves amplitude balance in multi-channel audio or sensor multiplexing. |
| Analog Signal Range | Rail-to-rail: VCOM, VNO = V− to V+ - supports full dynamic range signal switching without clipping in ±15V systems. |
| Logic Compatibility | +3V logic: VIH = 2.0V, VIL = 0.8V - interfaces directly with 3.3V FPGA I/O, ARM GPIO, or CPLD outputs without level shifters. |
| Turn-On/Turn-Off Time | 275ns / 235ns max (dual supply) - enables reliable switching in sub-microsecond timing-critical data acquisition cycles. |
| Off-Leakage Current | ±2.5nA max at +85°C - prevents DC error accumulation in high-impedance sample-and-hold or integrator circuits. |
Pinout & Package
MAX313LCUE+ 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+ per manufacturer recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1, IN2, IN3, IN4 | CMOS logic inputs controlling respective NO switches - active-high, +3V compatible. |
| 2, 7, 10, 15 | COM1, COM2, COM3, COM4 | Analog common terminals - bidirectional signal path entry points for each switch. |
| 3, 6, 11, 14 | NO1, NO2, NO3, NO4 | Normally open analog outputs - connect only when corresponding INx is high. |
| 4 | V− | Negative analog supply pin - tie to GND for single-supply operation; required for dual-supply biasing. |
| 5 | GND | Ground reference for logic and substrate - must be low-impedance connection to minimize noise coupling. |
| 12 | N.C. | No internal connection - leave unconnected; not electrically tied to die. |
| 13 | V+ | Positive analog supply pin - powers analog core and defines upper rail of signal range. |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility | Direct replacement for MAX313 and industry-standard DG412 - enables drop-in upgrade in existing layouts without redesign. |
| RON flatness | 2Ω max variation across full analog signal range - maintains consistent gain and THD in audio and instrumentation signals. |
| Rail-to-rail switching | Supports signals from V− to V+ - eliminates need for external clamping or level-shifting in ±15V industrial control interfaces. |
| Zero power-supply sequencing requirement | No VL pin or strict V+/V−/GND power-up order - simplifies system power architecture and reduces BOM count. |
| Low crosstalk | >96dB at 20kHz - prevents audible interference in multi-channel audio routing and adjacent-channel signal leakage in test fixtures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX313CSE+ | Same function and pinout, but in 16-pin narrow SO package; higher thermal resistance (8.70mW/°C derating vs. 6.7mW/°C for TSSOP). | Suitable for through-hole or larger PCB footprints where TSSOP reflow is impractical. | Select MAX313CSE+ when board assembly uses wave soldering or requires SOIC footprint compatibility. |
| DG412DN+ | Industry-standard quad NO switch; 35Ω max RON (vs. 10Ω), no guaranteed RON match, and requires strict V+/V− sequencing. | Acceptable in cost-sensitive, non-precision applications where leakage & matching are less critical. | Choose DG412DN+ only if legacy design reuse or lower unit cost outweighs performance trade-offs in RON and sequencing freedom. |
Compared with MAX313CSE+, the MAX313LCUE+ offers superior thermal performance and smaller footprint; versus DG412DN+, it delivers 3.5× lower on-resistance, guaranteed matching, and eliminates sequencing constraints - directly improving accuracy and design robustness in new layouts.

FAQ
What is the operating temperature range for MAX313LCUE+?
The MAX313LCUE+ is specified for 0°C to +70°C ambient operation. This commercial-grade temperature range is validated per Maxim's datasheet ordering information and applies to the 16-pin TSSOP package variant. It is not rated for extended industrial temperatures (–40°C to +85°C), which require the MAX313LEUE+ variant.
Does MAX313LCUE+ support single-supply operation?
Yes, MAX313LCUE+ supports single-supply operation from +4.5V to +36V. In this mode, V− must be connected to GND, and analog signals swing from 0V to V+. The device maintains rail-to-rail signal handling and retains its 10Ω max RON, though RON increases slightly versus dual-supply conditions (35Ω max at +12V, per datasheet Section "Electrical Characteristics-Single Supply").
Is MAX313LCUE+ pin-compatible with older MAX313 devices?
Yes, MAX313LCUE+ is pin-compatible with the legacy MAX313 (non-L) and industry-standard DG412. The pinout, package dimensions, and electrical interface are identical across TSSOP, SO, and DIP variants. However, MAX313LCUE+ removes the VL pin and eliminates power-supply sequencing requirements - a functional enhancement that does not affect physical compatibility.
What is the maximum analog signal voltage supported by MAX313LCUE+?
MAX313LCUE+ supports analog signals from V− to V+, with absolute maximum ratings of V+ ≤ +44V and V− ≥ –44V. Under recommended operating conditions, it functions reliably with dual supplies up to ±20V or single supply up to +36V. Signal voltages exceeding these rails are clamped by internal diodes, so external limiting is advised for transient overvoltage protection.
How does MAX313LCUE+ achieve low THD in audio applications?
MAX313LCUE+ achieves low total harmonic distortion (THD) through ultra-low and highly linear on-resistance (10Ω max, 2Ω flatness), minimal charge injection (±30pC), and symmetrical switch architecture. These characteristics preserve waveform integrity across the audio band - demonstrated in the datasheet's THD vs. frequency plots showing <0.01% THD at 1kHz with 600Ω load and 5VRMS signal - making it ideal for professional audio routing.
