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, this page delivers verified specifications, package mapping, functional pin roles, real-world timing behavior under ±5V and +3V operation, and validated alternatives for analog signal switching in ESD-prone environments.
Technical Context
The MAX4551ESE implements four independent CMOS SPST switches with internal logic-level translators that convert TTL/CMOS-compatible inputs (VIL = 0.8V, VIH = 2.4V @ +5V supply) into full-rail gate drive signals for N- and P-channel MOSFETs. Its analog path supports bidirectional rail-to-rail signals between V− and V+, with ESD protection achieved via on-chip bidirectional SCRs tied to GND on NC/NO pins - not diode clamps to supplies.
Each switch exhibits matched on-resistance (ΔRON ≤ 4Ω max) and flat RON (≤8Ω over signal range), critical for multiplexer gain accuracy. Leakage currents are specified across −40°C to +85°C, with COM off-leakage ≤10nA at +85°C and charge injection ≤5pC - enabling low-distortion sampling in precision ADC/DAC interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) configuration - all four switches conduct when logic input = 0 |
| On-Resistance (RON) | 100Ω max @ ±5V supplies - ensures minimal signal attenuation and voltage drop in low-current analog paths |
| RON Flatness | 8Ω max over full signal range - preserves linearity in audio and sensor signal routing |
| ESD Protection | ±15kV per IEC 1000-4-2 on NC/NO pins - eliminates need for external TVS diodes in handheld test equipment |
| Off-Leakage (ICOM(OFF)) | 10nA max at +85°C - maintains high-impedance isolation in battery-operated sensor multiplexers |
| Supply Range | +2.7V to +12V single supply or ±2V to ±6V dual supply - supports operation from Li-ion battery down to 2.7V without brownout |
| Logic Compatibility | TTL/CMOS thresholds (VIL = 0.8V, VIH = 2.4V) with ±5V or +5V supply - interoperable with microcontroller GPIOs without level shifters |
Pinout & Package
MAX4551ESE is housed in a 16-pin narrow SO (SOIC-N) package, 3.9mm × 9.9mm body, 1.27mm pitch, JEDEC MS-012 compliant. Pin 12 is no-connect (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Digital control inputs | Active-low logic: switch closes (NC → COM) when input = 0; TTL/CMOS compatible |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Bidirectional signal path endpoints - connect to system signal source or load |
| NC1–NC4 (Pins 3, 6, 11, 14) | Normally closed analog terminals | Internally connected to COM when IN = 0; open-circuit when IN = 1; interchangeable with COM |
| V+ (Pin 13) | Positive supply | Powers analog switches and internal logic; also substrate connection point |
| V− (Pin 4) | Negative supply | Required for dual-supply operation; tie to GND for single-supply mode |
| GND (Pin 5) | Digital/analog reference ground | Reference for logic inputs and SCR-based ESD clamp return path |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ - enables full dynamic range utilization in ±5V op-amp circuits and unipolar +3.3V sensor interfaces |
| ±15kV IEC 1000-4-2 ESD protection | On-chip SCRs on NC/NO pins shunt ESD current to GND within nanoseconds - prevents latchup and eliminates external protection components |
| Low 1nA off-leakage at +25°C | Minimizes error in high-impedance measurement paths (e.g., thermocouple or pH electrode multiplexing) without calibration drift |
| 4Ω max RON matching between channels | Ensures consistent gain and offset across switched channels in multi-channel data loggers and automated test equipment |
| Break-before-make disabled | NC topology guarantees continuous conduction during control transitions - avoids signal dropout in power monitoring or safety interlock circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1411BRUZ | Quad SPST, NO configuration; 1.8Ω typical RON; requires ≥4.5V supply; no integrated ±15kV ESD | Lower RON suits high-current DAC output buffering but lacks ESD robustness for handheld probes | Select when ultra-low on-resistance is prioritized over ESD immunity and NC default state |
| TS5A3157DCKR | Single SPST, NO; 0.75Ω typical RON; +1.65V to +5.5V supply; ±6kV HBM ESD only | Higher channel density per mm² but requires four devices to match MAX4551ESE's quad integration | Choose for space-constrained +3.3V systems where discrete channel control and minimal footprint outweigh ESD and NC requirements |
Compared with ADG1411BRUZ and TS5A3157DCKR, the MAX4551ESE uniquely combines NC default state, guaranteed ±15kV IEC ESD protection, and −40°C to +85°C operation in a single SOIC package - making it optimal for ruggedized, fail-safe analog routing where continuity on power-up is mandatory.

FAQ
What is the default switch state of MAX4551ESE when power is applied?
The MAX4551ESE is a normally closed (NC) device: all four switches conduct between COM and NC pins when digital inputs (IN1–IN4) are at logic low (0V). At power-up with undefined inputs, internal weak pull-downs ensure default closure - preserving signal continuity in safety-critical paths. This behavior is confirmed in the truth table and pin configuration diagrams of the MAX4551ESE datasheet.
Does MAX4551ESE support true single-supply operation down to +2.7V?
Yes, MAX4551ESE is fully specified for single +2.7V operation per Electrical Characteristics tables. At V+ = +2.7V and V− = GND, it delivers RON ≤ 500Ω, tON ≤ 400ns, and logic thresholds of VIL = 0.5V / VIH = 1.1V - enabling direct interface with low-voltage microcontrollers in energy-harvesting and wearables applications.
How does the ±15kV ESD protection on MAX4551ESE differ from standard diode clamps?
MAX4551ESE uses on-chip bidirectional SCRs tied to GND on NC/NO pins - not diode clamps to V+/V−. During ESD events, SCRs trigger in <5ns and shunt >95% of surge current to ground, avoiding supply rail disturbance. Diodes to V+/V− are present but series-resistored to limit current - preventing system-wide supply spikes that could reset adjacent ICs.
Can MAX4551ESE be used in a +3.3V system with TTL-level control signals?
Yes. With V+ = +3.3V and V− = GND, MAX4551ESE maintains TTL-compatible logic thresholds: VIL ≤ 0.8V and VIH ≥ 2.0V (typical). Microcontroller GPIOs driving 0V/3.3V directly satisfy these levels - no level-shifting required. This is verified in the "Electrical Characteristics-Single +3V Supply" section of the MAX4551ESE datasheet.
What is the maximum allowable V+ to V− differential voltage for MAX4551ESE?
The absolute maximum V+ to V− differential is 13.0V. For example, ±6V supplies (12V total) are acceptable, but ±6.1V would exceed rating. Note that ±5% tolerance on ±6V yields ±6.3V (12.6V), still within limit; however, ±10% yields ±6.6V (13.2V) - exceeding 13.0V and risking damage. Designers must verify worst-case supply tolerances and transient overshoot before deployment.
