Product details
Overview
MAX4551ESE+ from Maxim Integrated is a quad, low-voltage, normally closed (NC) SPST analog switch IC designed for rail-to-rail signal routing in battery-powered and precision analog systems. It features ±15kV IEC 1000-4-2 ESD protection on NC/NO pins, 100Ω max on-resistance (flatness ≤8Ω), 1nA COM off-leakage at +25°C, and operates from single +2.7V to +12V or dual ±2V to ±6V supplies - enabling use in portable data acquisition front-ends.
For engineers reviewing the MAX4551ESE+ datasheet, MAX4551ESE+ pinout, MAX4551ESE+ application, or MAX4551ESE+ equivalent, key selection criteria include its NC configuration, guaranteed -40°C to +85°C industrial temperature range, QSOP-16 package, ESD-hardened analog path, and compatibility with TTL/CMOS logic under +5V supply conditions.
Technical Context
The MAX4551ESE+ implements four independent CMOS SPST switches with internal N- and P-channel MOSFETs paralleled per channel, driven by phase-inverted gate signals derived from logic-level translators. Its analog path supports bidirectional rail-to-rail signals between V− and V+, with ESD protection achieved via on-chip SCRs tied to GND on NC/NO pins - not diode clamps to supplies.
Logic inputs feature fixed +0.8V/2.4V thresholds for TTL/CMOS compatibility across ±5V or +5V operation. The device uses separate analog (V+, V−) and digital (V+, GND) supply domains, with internal substrate connection to GND and no direct coupling between logic and analog power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) - all four switches conduct when IN = logic low. |
| On-Resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation and gain error in precision sensor interfaces. |
| On-Resistance Flatness | 8Ω max over full signal range - maintains consistent channel matching for multi-channel instrumentation. |
| ESD Protection | ±15kV contact discharge per IEC 1000-4-2 on NC/NO pins - eliminates need for external TVS diodes in handheld test equipment. |
| Off-Leakage Current | 1nA at +25°C, 10nA at +85°C - preserves accuracy in high-impedance pH or thermocouple measurement paths. |
| Supply Range | +2.7V to +12V single supply or ±2V to ±6V dual supply - supports operation from Li-ion battery (3.0–4.2V) without regulation. |
| Logic Compatibility | TTL/CMOS thresholds (+0.8V low / +2.4V high) at +5V supply - interoperable with microcontroller GPIO without level-shifting. |
Pinout & Package
MAX4551ESE+ is housed in a 16-pin QSOP (Quarter-size Outline Package) with 0.150" body width and 0.025" lead pitch, optimized for compact PCB layouts in portable instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Digital control inputs | Active-low logic: IN = low → NC path closed; compatible with 3.3V/5V MCU outputs. |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Bidirectional signal path endpoints - may serve as input or output depending on system topology. |
| NC1–NC4 (Pins 3, 6, 11, 14) | Analog normally closed terminals | Connected to corresponding COM pin when IN = low; open when IN = high - defines default-closed signal path. |
| V+ (Pin 13) | Positive analog/digital supply | Powers internal logic translators and P-MOS gates; also substrate connection point. |
| V− (Pin 4) | Negative analog supply | Drives N-MOS gates; connect to GND for single-supply operation - sets lower analog voltage limit. |
| GND (Pin 5) | Digital ground reference | Reference for logic inputs and ESD SCR return path; must be low-impedance plane for ESD current dissipation. |
| N.C. (Pin 12) | No connection | Internally unconnected - leave floating or tie to GND for mechanical stability; no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ without clipping - enables full dynamic range utilization in ±5V op-amp circuits. |
| ±15kV IEC 1000-4-2 ESD protection | On-chip SCRs on NC/NO pins clamp transients to GND in <5ns - meets Level 4 immunity without external components. |
| Low on-resistance matching (≤4Ω) | Ensures ≤0.1% gain mismatch across channels - critical for multi-channel ADC multiplexing with calibrated offset correction. |
| Ultra-low power consumption (<1µW) | Quiescent supply current <1µA - extends battery life in always-on sensor nodes and portable DMMs. |
| Pin-compatible with DG211 | Direct drop-in replacement for industry-standard quad SPST switch - simplifies legacy design upgrades and BOM rationalization. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4552ESE+ | Quad NO (normally open) configuration - requires active-high enable for conduction vs. MAX4551ESE+'s active-low NC behavior. | Suitable where default-open safety state is required (e.g., disconnecting power rails during fault). | Select MAX4552ESE+ only if system logic demands NO behavior; pinout and specs otherwise identical. |
| ADG1411BRUZ | Higher RON (1.8Ω typ), wider supply (±5V to ±15V), but no integrated ±15kV ESD protection - requires external TVS diodes. | Better for high-precision, low-RON applications where board area allows discrete ESD components. | Choose ADG1411BRUZ only when sub-2Ω RON is mandatory and ESD protection can be added externally. |
Compared with MAX4552ESE+, the MAX4551ESE+ provides fail-safe continuity without control power; versus ADG1411BRUZ, it trades 98Ω higher RON for integrated ESD robustness and smaller BOM count in portable designs.

FAQ
What is the operating temperature range of the MAX4551ESE+?
The MAX4551ESE+ is rated for -40°C to +85°C operation, verified across all electrical parameters in the datasheet. This industrial-grade range ensures reliable performance in outdoor test equipment, avionics bays, and automotive under-hood monitoring systems where ambient temperatures fluctuate widely. The MAX4551ESE+ maintains specified on-resistance flatness and leakage current limits throughout this span.
Does the MAX4551ESE+ require external ESD protection components?
No - the MAX4551ESE+ integrates ±15kV IEC 1000-4-2 ESD protection on all NC and NO pins using on-chip SCRs referenced to GND. This eliminates the need for external TVS diodes or RC filters in most handheld and field-deployable applications. However, 100nF supply bypass capacitors to GND are recommended to handle residual ESD current shunted through internal diodes.
Can the MAX4551ESE+ operate from a single 3.3V supply?
Yes - the MAX4551ESE+ supports single-supply operation from +2.7V to +12V. At +3.3V, it delivers 500Ω max on-resistance (typical 200Ω), 1.1V logic high threshold, and 190ns typical turn-on time. This makes it suitable for direct interfacing with 3.3V microcontrollers in portable sensors and IoT edge nodes without level shifters or supply boosting.
How does the MAX4551ESE+ differ from the MAX4553ESE+?
The MAX4551ESE+ contains four normally closed (NC) switches, whereas the MAX4553ESE+ integrates two NC and two NO switches in the same package. Both share identical pinout, supply ranges, ESD rating, and RON specs. The MAX4551ESE+ is selected when uniform NC behavior is required across all channels - such as maintaining default signal continuity in safety-critical monitoring paths.
Is the MAX4551ESE+ pin-compatible with legacy DG211 devices?
Yes - the MAX4551ESE+ is explicitly designed as a pin-compatible upgrade to the industry-standard DG211 quad SPST switch. It matches DG211's 16-pin SOIC and QSOP footprints, logic polarity, and basic timing, while adding ±15kV ESD protection, lower leakage, and extended temperature range. No PCB layout changes are needed for drop-in replacement in existing DG211-based designs.
