Product details
Overview
MAX4551ESE+T from Maxim Integrated is a quad, low-voltage, normally closed (NC) SPST analog switch IC designed for rail-to-rail signal routing in space-constrained, ESD-sensitive systems. It delivers 100Ω max on-resistance, ±15kV IEC 1000-4-2 ESD protection on NC/NO pins, 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 audio multiplexing and battery-powered data acquisition front-ends.
For engineers reviewing the MAX4551ESE+T datasheet, MAX4551ESE+T pinout, MAX4551ESE+T application, or MAX4551ESE+T equivalent, key selection criteria include its NC configuration, -40°C to +85°C extended temperature rating, QSOP-16 package, ESD-hardened analog path, and compatibility with TTL/CMOS logic under ±5V or +5V supply conditions.
Technical Context
The MAX4551ESE+T implements four independent CMOS SPST switches with complementary N- and P-channel MOSFETs per channel, driven by logic-level translators that convert TTL/CMOS inputs into full-rail V+ and V− gate drive signals. Its internal bidirectional SCRs provide ±15kV ESD protection on NC/NO pins without latchup, clamping transients to GND within nanoseconds while limiting supply current via series resistors.
Signal integrity is maintained via flat on-resistance (≤8Ω over ±4.5V range), matched channel RON (≤4Ω), and low charge injection (≤5pC). The device supports rail-to-rail analog operation, with leakage currents fully specified across -40°C to +85°C and dynamic switching times (tON/tOFF ≤ 170ns/150ns at ±5V) optimized for precision multiplexing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) - all four switches conduct when logic input = 0 |
| On-Resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation in low-impedance paths |
| RON Flatness | 8Ω max over ±4.5V signal range - preserves linearity for precision AC/DC signal routing |
| ESD Protection | ±15kV per IEC 1000-4-2 on NC/NO pins - eliminates need for external TVS diodes in end-equipment |
| Supply Range | +2.7V to +12V single or ±2V to ±6V dual - supports wide-input industrial and portable designs |
| Off-Leakage (ICOM_OFF) | 10nA max at +85°C - maintains high-impedance isolation in sensor and measurement circuits |
| Logic Compatibility | TTL/CMOS thresholds (VIN_H = 2.4V, VIN_L = 0.8V at +5V) - interoperable with standard microcontroller GPIO |
Pinout & Package
MAX4551ESE+T is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.65mm pitch, 5.0mm × 3.99mm body, and exposed pad not connected internally. Pin 12 is no-connect (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs - active-low logic drives NC closure; 0 = ON, 1 = OFF |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path endpoints for each switch |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - conduct to COM when IN = 0; open when IN = 1 |
| 4 | V− | Negative supply input - connect to GND for single-supply operation; sets lower analog rail |
| 5 | GND | Digital ground reference - separate from analog signal reference; required for SCR ESD return path |
| 13 | V+ | Positive supply input - powers analog switches and internal logic; internally tied to substrate |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ (e.g., −5V to +5V or 0V to +5V) without clipping or distortion |
| ±15kV IEC 1000-4-2 ESD protection | Integrated SCRs on NC/NO pins eliminate external protection components and reduce BOM cost |
| Low power consumption | <1µW quiescent power - enables always-on signal routing in battery-critical applications |
| Channel-to-channel RON matching | ≤4Ω max mismatch - ensures consistent gain/attenuation across multiplexed channels |
| Break-before-make isolation (MAX4553 only) | Not applicable - MAX4551ESE+T is NC-only; no BBM timing required for channel switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4552ESE+T | Quad NO (normally open) configuration - conducts only when IN = 1; identical RON, ESD, and supply specs | Suitable where default-open safety state is required (e.g., power-off signal isolation) | Select MAX4552ESE+T if fail-safe open-circuit behavior is mandated; otherwise MAX4551ESE+T provides default-closed continuity. |
| ADG1411BRUZ | Quad SPST, NO, 1.8Ω typical RON, ±15kV HBM ESD, but only ±4kV IEC 1000-4-2 rated on switch pins | Lacks certified ±15kV IEC contact/air-gap ESD robustness - requires external protection for Level 4 compliance | Choose ADG1411BRUZ only in non-certified environments; MAX4551ESE+T is preferred for medical, avionics, or industrial ESD-critical designs. |
Compared with MAX4552ESE+T and ADG1411BRUZ, the MAX4551ESE+T uniquely combines NC default state, full ±15kV IEC 1000-4-2 certification on switch terminals, and guaranteed -40°C to +85°C performance - making it the optimal choice for safety-critical, ESD-prone signal routing where continuity at power-up is essential.

FAQ
What is the default switch state of MAX4551ESE+T?
The MAX4551ESE+T features four normally closed (NC) SPST switches. When all digital inputs (IN1–IN4) are held at logic low (0V or near GND), the corresponding NC-to-COM paths are conductive. Applying logic high (≥2.4V) to any IN pin opens that channel. This default-closed behavior ensures signal continuity during power-up or controller reset - a key safety feature in monitoring and control systems using MAX4551ESE+T.
Does MAX4551ESE+T require external ESD protection components?
No. The MAX4551ESE+T integrates bidirectional SCRs on all NC and NO pins, delivering certified ±15kV ESD protection per IEC 1000-4-2 (contact and air-gap discharge). This eliminates the need for external TVS diodes or RC networks in most end-equipment designs. However, 100nF bypass capacitors on V+ and V− pins are recommended to absorb residual ESD energy shunted through internal diodes - a best practice confirmed in the MAX4551ESE+T application notes.
Can MAX4551ESE+T operate from a single +3.3V supply?
Yes. The MAX4551ESE+T is fully specified for single-supply operation from +2.7V to +12V. At +3.3V, it maintains rail-to-rail analog capability (0V to +3.3V), logic thresholds compatible with 3.3V CMOS (VIN_H = 2.0V min), and on-resistance of 500Ω max. Switching times increase to 400ns (tON) and 300ns (tOFF) at +2.7V, but remain functional for medium-speed multiplexing - verified in the MAX4551ESE+T electrical characteristics table for single +3V supply.
How does the SCR-based ESD protection affect normal operation of MAX4551ESE+T?
The integrated SCRs in MAX4551ESE+T remain fully off during normal operation, drawing negligible current and introducing no measurable impact on on-resistance, leakage, or signal integrity. They activate only during ESD events (>±8kV), clamping voltage within nanoseconds. Post-event, SCRs self-reset once current falls below holding threshold (70mA at +85°C). No latch-up occurs, and MAX4551ESE+T resumes full functionality without intervention - a behavior validated in Maxim's reliability reports for MAX4551ESE+T.
Is MAX4551ESE+T pin-compatible with industry-standard analog switches?
Yes. The MAX4551ESE+T shares identical pinout, footprint, and logic behavior with the DG211 (quad NC) switch. This allows drop-in replacement in existing designs using DG211, DG212, or DG213 - provided the extended temperature range (-40°C to +85°C), lower leakage, and superior ESD rating of MAX4551ESE+T are leveraged. Layout changes are unnecessary, and no firmware or schematic modifications are required for migration to MAX4551ESE+T.
