Product details
Overview
MAX4551CPE 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), and 1nA COM off-leakage at +25°C. It operates from single +2.7V to +12V or dual ±2V to ±6V supplies and supports TTL/CMOS logic inputs.
For engineers reviewing the MAX4551CPE datasheet, MAX4551CPE pinout, MAX4551CPE application, or MAX4551CPE equivalent, this device is selected for high-reliability analog switching where ESD robustness, low leakage, matched on-resistance, and rail-to-rail signal handling are critical - especially in portable instrumentation, avionics signal conditioning, and audio routing with minimal distortion.
Technical Context
The MAX4551CPE implements four independent CMOS SPST switches with internal N- and P-channel MOSFETs paralleled per channel to enable rail-to-rail analog conduction. Its logic-level translators convert TTL/CMOS-compatible inputs (1.6V/2.4V thresholds at +5V supply) into full-rail gate drive signals referenced to V+ and V−, ensuring low on-resistance across the signal range.
ESD protection uses on-chip bidirectional SCRs between NC/NO pins and GND - not diode clamps to supplies - enabling ±15kV contact discharge immunity without supply rail disturbance. Holding current is 110mA (positive) / 95mA (negative) at +25°C, requiring external current limiting below ~35mA at +85°C to guarantee SCR turn-off after ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 100Ω max - ensures minimal voltage drop and gain error in precision signal paths at ±5V supplies |
| On-Resistance Flatness | 8Ω max over signal range - maintains consistent gain and linearity for audio and data acquisition |
| COM Off-Leakage Current | 1nA at +25°C - preserves accuracy in high-impedance sensor interfaces and sample-hold circuits |
| ESD Protection | ±15kV per IEC 1000-4-2 on NC/NO pins - eliminates need for external TVS diodes in field-deployed equipment |
| Supply Range | +2.7V to +12V single or ±2V to ±6V dual - supports operation from Li-ion battery (3.0–4.2V) up to industrial 12V rails |
| Logic Thresholds | VIN_H = 2.4V, VIN_L = 0.8V at +5V - guarantees reliable interfacing with standard TTL and CMOS controllers |
| Turn-On/Off Time | 125ns / 100ns typical at ±5V - enables fast multiplexing in data acquisition and test equipment |
Pinout & Package
MAX4551CPE is housed in a 16-pin plastic DIP package (0.300" wide), RoHS-compliant, with through-hole mounting and 0.1" pin pitch. 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 selects NC closure (logic '0' = ON for MAX4551) |
| 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; connected to COM when IN = 0; isolated when IN = 1 |
| 4 | V− | Negative analog supply input; tied to GND for single-supply operation |
| 5 | GND | Digital ground reference; SCR ESD return path; must be low-impedance plane |
| 13 | V+ | Positive analog/digital supply; powers logic translators and switch gates; internally tied to substrate |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ without clipping - essential for full-scale ADC/DAC interfacing |
| ±15kV IEC 1000-4-2 ESD on NC/NO | On-chip SCR-based protection eliminates external components and avoids supply rail coupling during ESD events |
| 4Ω max RON match between channels | Enables precise multi-channel gain matching in instrumentation amplifier front-ends and sensor arrays |

IC Role / Device Role: Low-distortion, low-capacitance analog switch with 10pF COM on-capacitance and <0.01% THD at 1kHz. Use Value: 8Ω on-resistance flatness ensures consistent frequency response across channels; rail-to-rail support avoids clipping on high-headroom signals. |
Use Scenario: Configuring stimulus/sense paths for semiconductor parametric testing, requiring fast, repeatable, low-leakage switching between DUT pins and measurement instruments. IC Role / Device Role: Quad SPST switch with 125ns turn-on time and 1nA leakage used in multiplexer front-end for picoampere-level current measurements. Use Value: Matched 4Ω RON minimizes channel-to-channel gain error; low charge injection (2pC typ.) prevents voltage glitches in sensitive integrator circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4552CPE | Same package, pinout, and specs - but configured as four normally open (NO) switches instead of NC | Suitable where default-open safety state is required (e.g., fail-safe sensor disconnect) | Select MAX4552CPE when circuit requires open-circuit default; otherwise MAX4551CPE provides continuity on power-up/reset. |
| ADG1411BRZ | Higher on-resistance (1.8Ω typ. at ±15V), wider supply range (±5V to ±22V), lower leakage (0.5nA), but no integrated ±15kV ESD protection | Requires external ESD protection for harsh environments; better for high-voltage industrial signal chains | Choose ADG1411BRZ only if >±15V operation is needed and external ESD design is acceptable; MAX4551CPE offers superior integration for portable +5V systems. |
Compared with MAX4552CPE and ADG1411BRZ, the MAX4551CPE uniquely combines NC default state, ±15kV on-chip ESD, and sub-100Ω on-resistance in a DIP package - making it optimal for cost-sensitive, space-constrained, and field-deployed analog multiplexing where reliability and simplicity are prioritized over ultra-low RON or extended voltage range.

FAQ
What is the operating temperature range for the MAX4551CPE?
The MAX4551CPE is rated for commercial temperature operation from 0°C to +70°C. This range is confirmed in the Ordering Information table and applies specifically to the 'C' grade suffix in the part number. The 'E' grade variant (e.g., MAX4551EPE) extends to –40°C to +85°C, but MAX4551CPE itself is guaranteed only within the 0°C to +70°C window.
Does the MAX4551CPE require external ESD protection components?
No - the MAX4551CPE integrates ±15kV ESD protection per IEC 1000-4-2 on its NC and NO pins using on-chip SCRs. This eliminates the need for external TVS diodes or RC networks in most applications, provided external current sources connected to NC/NO pins are limited to <35mA at +85°C to ensure SCR turn-off after an ESD event.
Can the MAX4551CPE operate from a single 3.3V supply?
Yes - the MAX4551CPE supports single-supply operation from +2.7V to +12V. At +3.3V, its typical on-resistance is 500Ω (max), logic thresholds shift to VIN_H = 2.0V and VIN_L = 0.5V, and turn-on time increases to 350ns. These values are fully specified in the Electrical Characteristics table for single +3V supply conditions.
How does the MAX4551CPE differ from the MAX4553CPE?
The MAX4551CPE contains four normally closed (NC) switches, whereas the MAX4553CPE integrates two NC and two NO switches in the same 16-pin DIP package. Both share identical electrical specs, ESD rating, and pinout compatibility, but MAX4553CPE adds break-before-make timing (5–20ns) on its dual-mode channels - a feature absent in MAX4551CPE's all-NC configuration.
Is the MAX4551CPE pin-compatible with the DG211 series?
Yes - the MAX4551CPE is explicitly documented as pin-compatible with the industry-standard DG211, DG212, and DG213 analog switches. This allows direct substitution in existing layouts without PCB modification, retaining identical footprint, pin functions, and mechanical dimensions in the 16-pin DIP package.
