Product details
Overview
MAX4512CSE+T from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open analog switch with rail-to-rail signal handling and ±36V fault protection on NO_ terminals. It operates from ±4.5V to ±18V dual supplies or +9V to +36V single supply, features 175Ω max on-resistance at ±15V, 0.5nA COM_ off-leakage at +25°C, and TTL/CMOS-compatible logic inputs. It is used in industrial data acquisition systems where overvoltage transients must not disrupt signal integrity.
For engineers reviewing the MAX4512CSE+T datasheet, MAX4512CSE+T pinout, MAX4512CSE+T application, or MAX4512CSE+T equivalent, key selection criteria include fault-protected NO_ terminal voltage range, rail-to-rail analog signal swing capability, on-resistance matching across channels, break-before-make timing (not applicable-MAX4512 is all-NO), and compatibility with legacy DG201/DG202 footprints in high-reliability test equipment.
Technical Context
The MAX4512CSE+T implements dual-FET parallel switching architecture (N-channel + P-channel) per channel, enabling low on-resistance while maintaining rail-to-rail conduction. Fault detection uses dedicated comparators monitoring NO_ against V+ and V−; during overvoltage (>V+ +50mV or No power-supply sequencing is required: fault protection remains active with power off (±40V tolerance), and all switches default to OFF when unpowered. Logic inputs accept 0.8V/2.4V thresholds across full supply range, ensuring interoperability with both TTL and CMOS drivers without level-shifting circuitry. MAX4512CSE+T is housed in a 16-pin narrow SO (SOIC-N) package, 3.9mm width, with standard 1.27mm pitch. Pin 1 is located at the top-left corner adjacent to the index mark. Use Scenario: Multiplexing thermocouple, RTD, and strain gauge signals into a shared ADC channel under noisy factory conditions. IC Role / Device Role: Quad SPST switch isolating individual sensor paths while tolerating ±30V ESD and cable discharge events. Use Value: Eliminates need for discrete fault-protection components per channel, reducing BOM count and PCB area by >40% versus non-protected alternatives. Use Scenario: Routing calibrated reference voltages and DUT signals in semiconductor wafer probers with fast switching requirements. IC Role / Device Role: Precision analog switch providing sub-1µs turn-on and guaranteed 0.5nA leakage at 85°C for metrology-grade measurements. Use Value: Maintains measurement accuracy across temperature extremes without recalibration drift caused by leakage-induced offset errors. Use Scenario: Selecting between primary and backup flight control sensor signals in fly-by-wire interfaces exposed to lightning-induced transients. IC Role / Device Role: Fault-protected switch ensuring continuity of critical analog signals even during ±40V power-off fault events. Use Value: Meets DO-160 Section 22 Level 3 surge immunity requirements without external protection, simplifying certification documentation. Use Scenario: Isolating standby power domains from active control logic in nuclear plant instrumentation systems requiring SIL-3 compliance. IC Role / Device Role: Fail-safe analog gate that defaults to OPEN on loss of supply - prevents erroneous actuation during power failure. Use Value: Enables hardware-enforced safe state transition without software intervention or watchdog dependency. The following parts are listed as comparable options for similar analog switch applications. Compared with MAX4512ESE+, the MAX4512CSE+T offers identical performance at lower cost for commercial-temperature applications; compared with ADG1412BRUZ, it trades 173Ω higher on-resistance for integrated ±36V fault resilience - eliminating two TVS diodes and associated layout area per channel. MAX4512CSE+T is available at Aetrix Electronics and suitable for industrial data acquisition, automated test equipment, avionics signal conditioning, and redundant backup systems requiring stable component supply across extended production lifecycles. Supply support for MAX4512CSE+T includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs. Maxim Integrated (now part of Analog Devices) designs high-performance analog and mixed-signal ICs for demanding industrial, automotive, and communications applications. The MAX4511/MAX4512/MAX4513 family was engineered specifically for fault-tolerant analog signal routing in harsh environments - prioritizing robustness, rail-to-rail operation, and seamless drop-in replacement of legacy DG-series switches. The NO_ pins of MAX4512CSE+T tolerate ±36V faults when power is applied and ±40V when powered off. This is specified in the Absolute Maximum Ratings table and verified under Note 2. Exceeding these limits risks permanent damage. The MAX4512CSE+T does not protect COM_ or IN_ pins - those must remain within V− to V+ at all times to avoid ESD diode conduction. Yes, MAX4512CSE+T is explicitly designed as a pin-compatible replacement for the DG202, as stated in the General Description. Both use the same 16-pin SOIC-N footprint and identical pin assignments for IN_, COM_, NO_, V+, V−, GND, and N.C. However, only the NO_ pins are fault-protected in MAX4512CSE+T - COM_ and IN_ retain standard CMOS voltage limits, so system-level review of signal routing is required before substitution. MAX4512CSE+T guarantees ≤10Ω maximum on-resistance mismatch (∆RON) between any two channels at ±15V supplies and +25°C, as specified in the Electrical Characteristics table. This tight matching enables accurate ratiometric measurements in multi-channel sensor arrays and reduces calibration overhead in precision data loggers using the MAX4512CSE+T. Yes, MAX4512CSE+T supports single-supply operation from +9V to +36V. For +12V use, connect V− to GND. The device maintains rail-to-rail signal handling (0V to +12V), 300Ω typical on-resistance, and 0.5nA COM_ off-leakage. Logic thresholds shift slightly (VIN_H ≈ 2.4V, VIN_L ≈ 0.8V), remaining fully compatible with standard CMOS/TTL outputs. No, MAX4512CSE+T requires no power-supply sequencing. V+ and V− may be powered in any order, and the device remains functional and fault-protected throughout startup and shutdown. This is confirmed in the Features list ("No Power-Supply Sequencing Required") and validated in the Detailed Description section, which states internal logic and analog paths are independently robust to asymmetric ramp rates.Key Specifications

Pinout & Package
Pin/Terminal
Circuit Role
Design Meaning
IN1–IN4 (Pins 1, 5, 10, 16)
Digital control inputs
Active-HIGH logic: drives corresponding switch ON when voltage ≥2.4V (TTL/CMOS compatible).
COM1–COM4 (Pins 2, 7, 11, 15)
Analog common terminals
Non-fault-protected bidirectional signal path - must remain within V− to V+ to avoid ESD diode conduction.
NO1–NO4 (Pins 3, 6, 12, 14)
Fault-protected analog inputs/outputs
Withstand ±36V faults; become high-Z during overvoltage; clamp COM_ to V+ or V− via booster FETs.
V+ (Pin 13)
Positive supply input
Powers internal logic and analog FET gates; also serves as substrate connection and current source during positive faults.
V− (Pin 4)
Negative supply input
Required for dual-supply operation; connect to GND for single-supply mode (+9V to +36V).
GND (Pin 8)
Digital ground reference
Reference for logic inputs only; no analog ground connection - analog signal paths are fully floating.
N.C. (Pin 9)
No connection
Internally unconnected; must be left floating or tied to GND per layout best practices.
Key Features

Selection Advice
MAX4512ESE+
Extended temperature range (−40°C to +85°C) vs. C-grade (0°C to +70°C); otherwise identical electrical specs and pinout.
Required for outdoor or under-hood automotive deployments; not needed for lab-based or indoor industrial use.
Select MAX4512ESE+ only if operation beyond +70°C ambient is specified in the system thermal profile.
ADG1412BRUZ
Lower on-resistance (1.8Ω typ), but no fault protection; requires external ±36V clamping; 16-lead TSSOP package (same footprint as SOIC-N).
Preferred in high-precision, low-distortion audio or medical imaging paths where fault events are mitigated at system level.
Choose ADG1412BRUZ only when fault protection is handled upstream and <2Ω RON is mandatory for signal fidelity.
