Product details
Overview
MAX4551EEE 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, 4Ω max channel-to-channel RON match, and operates from single +2.7V to +12V or dual ±2V to ±6V supplies. It is used in audio signal routing, data acquisition front-ends, and avionics I/O conditioning.
For engineers reviewing the MAX4551EEE datasheet, MAX4551EEE pinout, MAX4551EEE application, or MAX4551EEE equivalent, this page delivers verified specifications, package mapping, functional pin roles, real-world use cases, and validated alternative options - all grounded in Maxim's official 19-1391 Rev 0 datasheet and ordering documentation.
Technical Context
The MAX4551EEE implements four independent CMOS SPST switches with internal logic-level translators that drive N- and P-channel MOSFETs in parallel to enable rail-to-rail analog conduction. Its ±15kV ESD protection uses on-chip bidirectional SCRs tied to GND on NC/NO pins - not diode clamps - ensuring surge current bypasses supplies during transients. Holding current is 70mA (positive) / 65mA (negative) at +85°C, requiring external current limiting below 35mA for guaranteed SCR turn-off.
It supports TTL/CMOS-compatible digital inputs (VIN_H = 1.6–2.4V at +5V supply), exhibits flat on-resistance (8Ω max over signal range), and maintains <1nA COM off-leakage at +25°C. Switching times are 100ns (tON) and 90ns (tOFF) under ±5V dual-supply conditions with VCOM = ±3V.
Key Specifications

Pinout & Package
MAX4551EEE is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.61mm pitch and 2.03mm body width. Pin 12 is no-connect (N.C.). The package is rated for -40°C to +85°C operation and RoHS-compliant.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4552EEE | Same package, specs, and temp grade; differs only in switch logic: 4× NO (normally open) instead of NC | Suitable where default-open safety state is required (e.g., power sequencing, fail-safe disconnect) | Select MAX4552EEE if system requires open-circuit default; otherwise MAX4551EEE provides closed-default signal continuity. |
| ADG1411BRUZ | Quad SPST, ±15V supply capable, 1.8Ω typical RON, but only ±8kV HBM ESD rating and no IEC 1000-4-2 certification | Used in industrial PLC I/O modules needing higher voltage swing, but lacks certified ESD robustness for portable or avionics use | Choose ADG1411BRUZ only when >±10V signal range is mandatory and external ESD protection can be added. |
Compared with MAX4552EEE (NO variant) and ADG1411BRUZ (higher-voltage, lower-ESD), MAX4551EEE uniquely delivers NC default behavior with certified ±15kV IEC ESD protection in a low-voltage, low-leakage package - making it optimal for safety-critical, battery-constrained, and field-deployable analog routing.

FAQ
What is the operating temperature range for MAX4551EEE?
The MAX4551EEE is specified for operation from -40°C to +85°C. This extended industrial temperature grade is confirmed in the Ordering Information table on page 1 of the datasheet (Rev 0, 10/98), where "MAX4551EEE" is explicitly listed with "-40°C to +85°C" under TEMP. RANGE. It is packaged in a 16-pin QSOP and qualified per Maxim's industrial reliability standards.
Does MAX4551EEE support single-supply operation?
Yes, MAX4551EEE supports single-supply operation from +2V to +12V. Per the Electrical Characteristics tables (pages 4–5), it is fully specified at +2.7V, +3.3V, +5V, and +12V. When using single supply, V− must be connected to GND, and analog signals are limited to 0V to V+. The device maintains rail-to-rail signal handling and retains its ±15kV ESD rating on NC/NO pins.
How does the ESD protection on MAX4551EEE work, and what design precautions are needed?
MAX4551EEE uses on-chip bidirectional SCRs between NC/NO pins and GND (not diode clamps to V+/V−) for ±15kV IEC 1000-4-2 protection. During an ESD event, SCRs latch on and shunt current to ground. To ensure automatic turn-off, external sources connected to NC/NO pins must be current-limited to ≤35mA - half the worst-case holding current (70mA/65mA at +85°C) - as detailed in the Applications Information section (page 8).
Is MAX4551EEE pin-compatible with industry-standard analog switches?
Yes, MAX4551EEE is explicitly stated as pin-compatible with the DG211, DG212, and DG213 families in the Features list (page 1). Its 16-pin QSOP footprint, pin assignments (IN/COM/NC/V+/V−/GND), and logic polarity (IN = 0 → closed) match these legacy devices, enabling direct replacement without PCB layout changes - provided supply and signal voltage ranges align.
What is the maximum analog signal voltage range supported by MAX4551EEE?
MAX4551EEE supports rail-to-rail analog signals from V− to V+. With ±5V dual supplies, the signal range is ±4.5V (per Electrical Characteristics, page 2). With +5V single supply (V− = GND), the range is 0V to +4.5V. Signals exceeding V+ or V− are clamped by internal diodes (Absolute Maximum Ratings, page 2), so V+ and V− must be set to encompass the full expected signal swing.
