Product details
Overview
MAX4551CEE 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 ESD-sensitive systems. It features ±15kV IEC 1000-4-2 ESD protection on NC/NO pins, 100Ω max on-resistance, 4Ω max channel matching, 1nA COM off-leakage at +25°C, and operation from +2.7V single supply or ±2V to ±6V dual supplies.
For engineers reviewing the MAX4551CEE datasheet, MAX4551CEE pinout, MAX4551CEE application, or MAX4551CEE equivalent, this device is selected for precision analog switching where ESD robustness, low leakage, tight RON matching, and rail-to-rail signal handling are critical - especially in portable data acquisition, avionics signal conditioning, and audio routing with TTL/CMOS-compatible control.
Technical Context
The MAX4551CEE implements four independent CMOS SPST switches with normally closed topology, each using paralleled N- and P-channel MOSFETs driven by logic-level translators referenced to V+ and V−. Its internal SCR-based ESD protection activates within nanoseconds during ±15kV contact discharge, clamping NC/NO pins to GND without latchup.
Signal integrity is maintained via flat on-resistance (8Ω max over full analog range), low charge injection (2–5pC), and minimal crosstalk (<−90dB). The device supports bidirectional analog signal flow between COM and NC terminals, with all digital inputs meeting TTL/CMOS thresholds (0.8V/2.4V) under ±5V or +5V supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation and voltage drop in precision analog paths. |
| RON Matching | 4Ω max between channels - enables matched gain/attenuation in multi-channel instrumentation and differential signal routing. |
| RON Flatness | 8Ω max over rail-to-rail signal range - preserves linearity and THD across full input voltage swing (V− to V+). |
| COM Off-Leakage Current | 1nA at +25°C - reduces error in high-impedance sensor interfaces and sample-and-hold circuits. |
| ESD Protection | ±15kV per IEC 1000-4-2 on NC/NO pins - eliminates need for external TVS diodes in handheld test equipment and field-deployable avionics. |
| Supply Range | +2.7V to +12V single or ±2V to ±6V dual - supports direct integration into 3.3V microcontroller systems and legacy ±5V signal chains. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V) at +5V - allows direct interfacing with FPGA GPIO, MCU outputs, and standard logic without level shifters. |
Pinout & Package
MAX4551CEE is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.025" lead pitch and exposed pad not connected internally. Package dimensions: 5.0mm × 4.0mm × 1.0mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-low logic selects NC closure (logic '0' = ON, '1' = OFF). |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals; bidirectional signal path connection point for each switch. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals; shorted to corresponding COM when IN = 0. |
| 4 | V− | Negative supply rail; tied to GND for single-supply operation; sets lower analog voltage limit. |
| 5 | GND | Digital ground reference; return path for logic circuitry and ESD SCR clamp current. |
| 12 | N.C. | No internal connection; must be left floating or grounded per layout best practice. |
| 13 | V+ | Positive supply rail; powers analog switches and logic translators; internally tied to substrate. |
Key Features
| Feature | Design Value |
|---|---|
| ±15kV IEC 1000-4-2 ESD protection | On-chip bidirectional SCRs on NC/NO pins enable system-level Level 4 ESD compliance without external components. |
| Rail-to-rail analog signal handling | Supports signals from V− to V+ (e.g., −5V to +5V or 0V to +3.3V), preserving full dynamic range in mixed-signal front-ends. |
| Low 1nA COM off-leakage at +25°C | Minimizes DC error in high-Z sensor multiplexing and precision measurement paths with >10MΩ source impedances. |
| 4Ω max RON matching between channels | Enables accurate channel-to-channel gain tracking in multi-input data loggers and balanced audio routing. |
| Pin-compatible with DG211 | Direct replacement for industry-standard quad SPST switches, simplifying upgrade paths in legacy designs. |
Applications
| Battery-Powered Data Acquisition | Avionics Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4552CEE | Quad NO (normally open) configuration vs. MAX4551CEE's NC topology; identical specs otherwise. | Suitable where default-open safety state is required (e.g., power-down isolation of sensitive loads). | Select MAX4552CEE when fail-safe open-circuit behavior is needed instead of default continuity. |
| ADG1411BRUZ | Lower 1.5Ω typical RON, but only ±5kV HBM ESD rating; requires external protection for IEC 1000-4-2 compliance. | Better for low-RON precision instrumentation where ESD threat is controlled; not suitable for handheld or field equipment. | Choose ADG1411BRUZ only in lab environments with strict ESD controls; MAX4551CEE remains preferred for uncontrolled user-accessible ports. |
Compared with MAX4552CEE, the MAX4551CEE provides fail-safe continuity on power loss; compared with ADG1411BRUZ, it delivers certified ±15kV system-level ESD robustness without added protection circuitry - reducing BOM count and PCB area in portable and aerospace designs.

FAQ
What is the maximum supply voltage range supported by the MAX4551CEE?
The MAX4551CEE operates from a single supply of +2.7V to +12V or dual supplies of ±2V to ±6V. The absolute maximum V+ to V− differential is 13.0V - exceeding this risks permanent damage. For reliable ±5V operation, ensure supply tolerances and transient spikes remain below 13.0V, as ±5V supplies with ±10% tolerance can reach 13.2V.
How does the MAX4551CEE achieve ±15kV ESD protection without external components?
The MAX4551CEE integrates on-die bidirectional SCRs between each NC/NO pin and GND. During an ESD event, these SCRs trigger in <5ns, shunting surge current safely to ground. Diodes to V+ and V− are also present but include series resistance to limit supply-line disturbance - eliminating the need for external TVS diodes in compliant system designs.
Is the MAX4551CEE pin-compatible with industry-standard analog switches?
Yes, the MAX4551CEE is pin-compatible with the DG211, DG212, and DG213 quad SPST analog switches. Its 16-pin QSOP footprint, identical pin functions (IN/COM/NC/V+/V−/GND), and logic polarity match allow drop-in replacement in existing layouts - provided the NC configuration aligns with system safety requirements.
What is the typical on-resistance flatness of the MAX4551CEE over its signal range?
The MAX4551CEE guarantees ≤8Ω on-resistance flatness (RON(MAX) − RON(MIN)) over the full specified analog signal range (V− to V+). This tight flatness ensures consistent gain and minimal harmonic distortion across the entire input voltage swing - critical for audio and precision measurement applications.
Can the MAX4551CEE operate from a +3.3V single supply, and what are the key performance trade-offs?
Yes, the MAX4551CEE is fully specified for +2.7V to +3.6V single-supply operation. At +3.3V, RON increases to 500Ω max (vs. 100Ω at ±5V), tON/tOFF rise to 400ns/300ns, and logic thresholds shift to 0.5V/1.1V. These trade-offs are acceptable in low-speed, low-power portable systems where ESD robustness outweighs speed or RON performance.
