Product details
Overview
MAX312CSE-T from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally closed (NC) CMOS analog switch optimized for precision signal routing in bipolar and single-supply systems. It delivers 6.5Ω typical on-resistance, 1.5Ω max on-resistance matching between channels, and rail-to-rail signal handling from ±4.5V to ±20V dual supplies or +4.5V to +30V single supply - enabling low-distortion audio switching and high-fidelity data acquisition.
For engineers reviewing the MAX312CSE-T datasheet, MAX312CSE-T pinout, MAX312CSE-T application, or MAX312CSE-T equivalent, key selection criteria include guaranteed RON flatness (≤2Ω), <2.5nA off-leakage at +85°C, >96dB crosstalk at 20kHz, ESD tolerance >2000V per Method 3015.7, and compatibility with DG411/DG412/DG413 footprints in 16-pin narrow SO packages.
Technical Context
The MAX312CSE-T implements a fully complementary CMOS transmission-gate architecture with matched P- and N-channel devices per channel, ensuring symmetrical conduction and minimal charge injection (±30pC). Its logic interface accepts TTL/CMOS-compatible inputs referenced to VL (2.4V high, 0.8V low), independent of analog supply rails.
It supports true rail-to-rail analog signal ranges: VCOM, VNC operate from V− to V+, with internal clamping diodes limiting overvoltage stress. Dynamic performance includes 65ns typical turn-on time, 185ns max turn-off time (dual-supply), and break-before-make timing only in the MAX314 variant - not applicable to MAX312CSE-T.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 6.5Ω typical, ≤10Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Matching | ≤1.5Ω max between channels - critical for matched gain/phase in multi-channel instrumentation |
| RON Flatness | ≤2Ω max over full signal range - maintains consistent gain across input amplitude, reducing THD |
| Off-Leakage Current | ±2.5nA max at +85°C - preserves accuracy in high-impedance sample-and-hold or sensor front-ends |
| Crosstalk | >96dB at 20kHz - prevents inter-channel interference in audio routing and multiplexed ADC systems |
| Supply Range | +4.5V to +30V single or ±4.5V to ±20V dual - enables operation in industrial, avionics, and test equipment power domains |
| ESD Protection | >2000V per Method 3015.7 - improves robustness during board handling and system integration |
Pinout & Package
MAX312CSE-T is housed in a 16-pin narrow SOIC (SO) package (JEDEC MS-012, 3.9mm width), with lead finish SnPb and RoHS-compliant variants available under different suffixes. Pin pitch is 0.050" (1.27mm), body width 0.150" (3.81mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Logic control inputs; active-low logic sense for NC function - INx = 0V turns switch ON (closed) |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path connection point for each SPST switch |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - connected to COM when INx = 0V; open when INx = high |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation; sets lower rail for analog signals |
| 5 | GND | Logic ground reference - separate from analog supplies to minimize noise coupling into digital control |
| 12 | VL | Logic supply voltage - accepts 2.7V to 5.5V; decouples logic threshold from analog rail voltages |
| 13 | V+ | Positive analog supply - defines upper analog signal limit; must be ≥ |V−| for proper operation |
Key Features
| Feature | Design Value |
|---|---|
| Pin-compatible replacement | Direct footprint match with DG411 - allows drop-in upgrade without PCB redesign |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - eliminates level-shifting in ±15V op-amp or DAC interfaces |
| Low charge injection | ±30pC max - minimizes voltage glitch in sample-and-hold and switched-capacitor circuits |
| Guaranteed RON flatness | ≤2Ω variation across ±10V signal range - ensures linear gain response in audio and instrumentation |
| High off-isolation | −65dB at 1MHz - suppresses crosstalk between inactive channels in dense multiplexers |
Applications
| Test Equipment Signal Routing | Avionics Sensor Multiplexing |
|---|---|

IC Role / Device Role / Timing Role: Quad SPST NC switch provides low-RON, low-leakage path selection with fast settling and no contact bounce. Use Value: 6.5Ω RON and ≤1.5Ω matching maintain measurement accuracy across channels; >96dB crosstalk prevents signal bleed between test sequences. | Use Scenario: Flight control computers aggregate analog outputs from redundant pressure, temperature, and position sensors. IC Role / Device Role / Timing Role: Normally closed configuration ensures default signal continuity during power-up or logic fault conditions. Use Value: Rail-to-rail ±20V dual-supply support matches aircraft power architecture; −55°C to +125°C variants exist (MAX312MJE), though MAX312CSE-T is 0°C to +70°C. |
| Audio Signal Switching | Data Acquisition Front-End |
Use Scenario: Professional audio mixers route line-level or microphone signals between processing stages without distortion. IC Role / Device Role / Timing Role: Low-THD analog switch with flat RON preserves harmonic integrity across 20Hz–20kHz bandwidth. Use Value: ≤2Ω RON flatness and ±30pC charge injection reduce audible artifacts; >96dB crosstalk prevents channel bleed in stereo paths. | Use Scenario: Industrial PLC modules condition and multiplex sensor outputs (thermocouples, strain gauges) before ADC sampling. IC Role / Device Role / Timing Role: Precision SPST switch isolates high-impedance sources during channel scanning to prevent loading errors. Use Value: 2.5nA max off-leakage at +85°C avoids offset drift in µV-level measurements; 10Ω max RON minimizes gain error in programmable-gain amplifier stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX313CSE-T | Same package and pinout, but normally open (NO) configuration - logic high closes switch | Suitable where default-open safety state is required (e.g., power enable, fail-safe cutoff) | Select MAX313CSE-T when circuit requires de-energized default state; MAX312CSE-T remains optimal for default-closed paths. |
| DG411DN | Pin-compatible, 16-pin SOIC, but higher 35Ω typical RON, no guaranteed RON matching, and no rail-to-rail support beyond ±15V | Acceptable in cost-sensitive, non-precision applications with moderate signal levels and bandwidth | Choose DG411DN only if budget constraints outweigh need for low distortion, tight matching, or extended supply range. |
Compared with MAX313CSE-T, MAX312CSE-T provides fail-safe continuity on power loss; versus DG411DN, it delivers 5.4× lower on-resistance, guaranteed matching, and superior THD performance - making it preferable for metrology-grade and high-fidelity signal routing.

FAQ
What is the operating temperature range for MAX312CSE-T?
The MAX312CSE-T is rated for 0°C to +70°C ambient operation. This commercial-grade temperature range aligns with its narrow SOIC packaging and target applications in benchtop test gear and office-grade audio equipment. For extended-range alternatives, Maxim offers the MAX312ESE-T (−40°C to +85°C) and MAX312MJE (−55°C to +125°C), but those use different package types and suffixes - MAX312CSE-T itself is strictly 0°C to +70°C.
Is MAX312CSE-T pin-compatible with the DG411 analog switch?
Yes, MAX312CSE-T is explicitly pin-compatible with the DG411, as confirmed in the "Features" section of the datasheet. Both use identical 16-pin SOIC footprints and share the same pin assignments for IN, COM, NC/NO, V+, V−, GND, and VL. This allows direct replacement in existing DG411 layouts without PCB modification - though designers must verify that the improved electrical specs (e.g., lower RON, better matching) do not require adjustments in downstream filtering or gain stages.
Does MAX312CSE-T support single-supply operation?
Yes, MAX312CSE-T supports single-supply operation from +4.5V to +30V, with V− connected to GND. In this mode, the analog signal range extends from 0V to V+, and the device maintains 12.5Ω typical RON at V+ = 12V. Logic inputs remain referenced to VL (2.7V to 5.5V), decoupling control thresholds from the analog rail - enabling clean interfacing with 3.3V or 5V microcontrollers even when V+ is 24V.
What is the maximum analog signal voltage range supported by MAX312CSE-T?
MAX312CSE-T supports analog signals from V− to V+, with absolute maximum ratings of V+ up to +44V and V− down to −44V. Under standard dual-supply operation (±15V), the usable signal range is ±10V - verified in electrical characteristics tables. The device's rail-to-rail capability means signals can swing fully between the supply rails without clipping or increased distortion, provided V+ and V− remain within their specified operating ranges (+4.5V to +30V or ±4.5V to ±20V).
How does the normally closed (NC) configuration of MAX312CSE-T affect system behavior during power loss?
The normally closed configuration means MAX312CSE-T conducts (switch closed) when all INx inputs are at logic low (0V). During power loss - i.e., when V+, V−, and VL are unpowered - the internal CMOS structure defaults to a high-impedance state, not a closed path. However, with powered supplies and un-driven (floating) IN pins, leakage currents may partially bias internal gates; thus, reliable NC behavior requires actively driving INx low. For true fail-safe continuity, external pull-down resistors on INx lines are recommended to ensure closure during controller reset or firmware hang - a design practice explicitly supported by the MAX312CSE-T's input current spec (±0.5µA max).
