Product details
Overview
MAX312LEUE+T from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally closed (NC) analog switch IC designed for precision signal routing in high-voltage, low-distortion systems. It delivers 10Ω max on-resistance, 1.5Ω max on-resistance matching between channels, and ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation - enabling rail-to-rail analog signal handling in test equipment and audio routing applications.
For engineers reviewing the MAX312LEUE+T datasheet, MAX312LEUE+T pinout, MAX312LEUE+T application, or MAX312LEUE+T equivalent, this page provides verified electrical specs, thermal range validation (-40°C to +85°C), TSSOP-16 package mapping, real-world leakage performance (2.5nA at +85°C), and direct alternatives with documented functional alignment.
Technical Context
The MAX312LEUE+T implements CMOS-based SPST switching with fully symmetric conduction - no directionality bias - and features integrated logic-level translation for +3V-compatible control inputs (VIH = 2.0V, VIL = 0.8V) across its full supply range. Its architecture eliminates latch-up risk via power-supply sequencing-free operation, removing the need for external protection diodes required by legacy MAX312 variants.
It guarantees RON flatness ≤4Ω over the full analog signal range and maintains off-isolation >75dB at 1MHz, while crosstalk remains >96dB at 20kHz - critical for multi-channel audio and data-acquisition signal integrity. The device supports break-before-make timing only in MAX314L variants; MAX312LEUE+T operates as pure NC switches without inter-channel timing coordination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max - ensures minimal voltage drop and signal attenuation in precision analog paths up to ±15V. |
| RON Matching | 1.5Ω max between channels - enables matched gain/attenuation in differential or multi-path signal conditioning. |
| Analog Signal Range | ±15V (dual supply) or 0 to +12V (single supply) - supports rail-to-rail signal handling without clipping. |
| Off-Leakage Current | ±2.5nA at +85°C - preserves accuracy in high-impedance sample-and-hold or sensor front-end circuits. |
| Turn-On/Off Time | 275ns / 235ns max (RL = 300Ω, CL = 35pF) - suitable for multiplexed data acquisition up to ~1MHz sampling rates. |
| Logic Compatibility | +3V input thresholds (VIH = 2.0V, VIL = 0.8V) - interfaces directly with modern microcontrollers and FPGAs without level-shifting. |
| Operating Temperature | -40°C to +85°C - qualified for industrial and avionics environments where thermal stability is critical. |
Pinout & Package
MAX312LEUE+T is housed in a 16-pin TSSOP package (package code U16-1), with exposed-pad variant not applicable - the +T suffix denotes tape-and-reel packaging, and the base part MAX312LEUE uses standard TSSOP without thermal pad. Pin functions are electrically identical across SO and DIP variants but physically mapped to TSSOP layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic Control Inputs | Active-low logic controls NC state; '0' = closed path, '1' = open path - compatible with +3V CMOS outputs. |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog Common Terminals | Signal entry points shared with NC contacts; bidirectional conduction supports AC/DC coupling without polarity constraints. |
| NC1–NC4 (Pins 3, 6, 11, 14) | Normally Closed Analog Outputs | Direct conductive path to COM when IN = 0; opens only upon logic high - used for default-signal or fail-safe routing. |
| V+ (Pin 13) | Positive Supply Rail | Accepts +4.5V to +36V (single) or +4.5V to +20V (dual); powers internal switch matrix and level translators. |
| V- (Pin 4) | Negative Supply Rail | Accepts -4.5V to -20V (dual); tied to GND for single-supply operation - enables true rail-to-rail analog swing. |
| GND (Pin 5) | Reference Ground | System ground reference for logic and analog sections; separate from power return paths to minimize noise coupling. |
| N.C. (Pin 12) | No Connection | Internally unconnected; must remain floating - no tie to GND or V+ to avoid parasitic coupling or ESD risk. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without distortion or clipping - essential for ±15V op-amp interfacing and audio line-level routing. |
| +3V logic compatibility | Operates with VIH = 2.0V and VIL = 0.8V across full temperature and supply range - eliminates level shifters in mixed-voltage systems. |
| Low charge injection (≤30pC) | Minimizes voltage glitch on sampled nodes - critical for precision sample-and-hold and ADC front-end multiplexing. |
| Guaranteed RON flatness (≤4Ω) | Ensures consistent gain/attenuation across full signal range (e.g., -10V to +10V), reducing harmonic distortion in audio paths. |
| Power-supply sequencing immunity | No VL pin or strict V+/V− ramp order required - simplifies power management in systems with asymmetric supply turn-on profiles. |
Applications
| Test Equipment Signal Routing | Avionics Sensor Multiplexing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX312LCUE | Same pinout and function, but rated 0°C to +70°C only; lower max junction temperature derating. | Restricted to commercial-grade systems without extended thermal cycling requirements. | Select when operating ambient stays within 0–70°C and cost sensitivity outweighs industrial temp margin. |
| ADG1412BRUZ | Quad SPST, NC, 1.8Ω RON typical (vs. 10Ω max), but requires ≥4.5V logic for full compatibility; no guaranteed RON match spec. | Better RON for ultra-low-loss paths, but lacks guaranteed matching and +3V logic compatibility at cold temps. | Prefer for low-RON priority in controlled lab environments; avoid where RON matching or wide-temp +3V logic drive is mandatory. |
Compared with MAX312LCUE, MAX312LEUE+T adds guaranteed -40°C operation and tighter thermal leakage control; versus ADG1412BRUZ, it trades lower absolute RON for broader logic compatibility, superior matching, and validated industrial temperature performance - making it optimal for field-deployed instrumentation.

FAQ
What is the maximum supply voltage rating for MAX312LEUE+T?
The MAX312LEUE+T supports dual supplies from ±4.5V to ±20V or single supply from +4.5V to +36V. Absolute maximum ratings specify V+ up to +44V and V− down to -44V, but continuous operation beyond ±20V or +36V violates datasheet limits and risks permanent damage. Always observe the recommended operating ranges for reliable lifetime performance.
Is MAX312LEUE+T pin-compatible with the legacy MAX312 series?
Yes, MAX312LEUE+T is pin-compatible with MAX312, MAX313, and MAX314 in all packages including TSSOP, SO, and DIP. It also maintains pin compatibility with DG411/DG412/DG413. However, the 'L' suffix indicates improved specifications - notably power-supply sequencing immunity and enhanced leakage performance at temperature - without requiring PCB changes.
Does MAX312LEUE+T support single-supply operation with ground-referenced signals?
Yes, MAX312LEUE+T supports true single-supply operation: connect V− to GND, apply V+ from +4.5V to +36V, and route analog signals from 0V to V+. In this configuration, the analog signal range spans 0V to V+, enabling seamless interface with ground-referenced sensors, DACs, and ADCs without level-shifting circuitry.
What is the guaranteed on-resistance matching specification for MAX312LEUE+T?
MAX312LEUE+T guarantees on-resistance matching (ΔRON) of ≤1.5Ω between any two channels under dual-supply conditions (V+ = +15V, V− = −15V, ICCOM = 10mA), tested over the full −40°C to +85°C operating range. This ensures consistent channel-to-channel gain in differential or parallel-switched configurations, critical for precision instrumentation.
Can MAX312LEUE+T be used in audio applications requiring low THD?
Yes, MAX312LEUE+T is explicitly characterized for low-distortion audio: THD is <0.01% at 1kHz with 5VRMS signal into 600Ω load, enabled by low RON (10Ω max), flat RON vs. voltage, and minimal charge injection (≤30pC). Its rail-to-rail capability and 96dB crosstalk at 20kHz make it suitable for professional line-level routing and mixer architectures.
