Product details
Overview
MAX4537EEE from Maxim Integrated is a quad, low-voltage, normally closed (NC) SPST analog switch with common enable, operating from ±2V to ±6V dual or +2V to +12V single supply. It delivers 200Ω max on-resistance, 4Ω max channel matching, 10Ω max on-resistance flatness, rail-to-rail signal handling, and 1nA max off-leakage at +25°C - enabling precision signal routing in battery-powered test equipment and avionics interfaces.
For engineers reviewing the MAX4537EEE datasheet, MAX4537EEE pinout, MAX4537EEE application, or MAX4537EEE equivalent, this page provides verified specifications, QSOP-16 package details, truth-table–validated switching behavior, leakage and timing performance across temperature, and direct alternatives for NC-configured quad analog switch replacement.
Technical Context
The MAX4537EEE implements four independent NC SPST switches sharing a single active-low EN input, with CMOS/TTL-compatible logic thresholds (0.8V/2.4V at +5V supply). Its internal architecture uses paralleled N- and P-channel MOSFETs per switch, driven by level-translated logic to V+ and V−, enabling rail-to-rail analog conduction without ground reference.
ESD protection (>2kV per Method 3015.7) is integrated via reverse-biased diodes between each analog pin and both supplies; leakage current flows exclusively to V+ or V−, not GND. Switching is characterized at ±4.5V (tON = 100ns, tOFF = 80ns) and +4.5V single supply (tON = 100ns, tOFF = 80ns), with charge injection limited to 5pC typical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) configuration - all switches conduct when EN = low, open when EN = high. |
| Supply Range | ±2V to ±6V dual supply or +2V to +12V single supply - supports portable, industrial, and avionics power architectures. |
| On-Resistance (RON) | 200Ω max at +25°C, +4.5V supply - ensures minimal signal attenuation in audio and sensor signal paths. |
| On-Resistance Matching | 4Ω max difference between channels - critical for matched gain/phase in multi-channel data acquisition. |
| Off-Leakage Current | 1nA max at +25°C, 10nA max at +85°C - preserves accuracy in high-impedance sensor front-ends. |
| Switching Speed | tON = 100ns, tOFF = 80ns at ±4.5V - enables reliable operation in 10MHz sampling systems. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V low / 2.4V high at +5V) - interoperable with microcontrollers and FPGAs without level shifters. |
Pinout & Package
MAX4537EEE is housed in a 16-pin QSOP package (5.0mm × 4.0mm, 0.635mm pitch), specified for -40°C to +85°C operation. Pin 1 is COM1; pins 2–3, 11–12 are NC1–NC4; pins 4, 10, 13 are COM2–COM4; pins 5–6, 14–15 are IN1–IN4; pin 7 is EN; pin 8 is GND; pins 9 and 16 are V− and V+ respectively.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 (COM1–COM4) | Analog common terminal (NC switch output) | Each connects to load/sensor; bidirectional rail-to-rail signal path with no ground reference required. |
| 2, 3, 11, 12 (NC1–NC4) | Analog normally closed terminal (NC switch input) | Conducts to corresponding COM when EN = low; opens when EN = high - default-closed safety path. |
| 5, 6, 14, 15 (IN1–IN4) | Digital control input per switch | Individually selects NC state override; inactive when EN = high - enables per-channel gating under global disable. |
| 7 (EN) | Global enable (active low) | Pulls all switches open when high; allows INx control only when low - simplifies system-level power sequencing. |
| 8 (GND) | Digital ground reference | Reference for logic inputs only; no analog current return path - eliminates ground-loop coupling in mixed-signal systems. |
| 9 (V−) | Negative analog supply | Set to GND for single supply; defines lower analog voltage limit and reduces P-MOSFET RON when negative. |
| 16 (V+) | Positive analog/digital supply | Drives analog switches and internal logic; substrate-connected - requires stable low-noise regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4316 | Direct drop-in replacement in legacy designs using industry-standard 16-pin SO/QSOP footprints and logic mapping. |
| Rail-to-rail analog signal handling | Supports signals from V− to V+ without clipping - essential for ±5V sensor outputs and unipolar 0–5V DAC interfaces. |
| Low 5pC typical charge injection | Minimizes voltage glitch on high-impedance nodes (e.g., sample-hold capacitors), preserving ADC measurement integrity. |
| 100% tested off-leakage at +85°C | Guarantees ≤10nA leakage in extended-temperature industrial environments - avoids drift in precision instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NC analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4537ESE | Same electrical specs and NC functionality; packaged in 16-pin narrow SO (3.9mm width) vs. QSOP's 4.0mm width - 0.1mm smaller body but identical pinout and thermal profile. | Preferred where board space permits SO footprint reuse; slightly higher thermal resistance (696mW vs. 800mW QSOP derating) limits high-power continuous use. | Select MAX4537ESE if existing layout uses narrow SO; choose MAX4537EEE for tighter pitch constraints or improved thermal dissipation in QSOP. |
| ADG1414BRUZ | Quad SPST, NC, but with 1.5Ω typical RON, 30ns tON/25ns tOFF, and ±15V supply capability - superior speed and on-resistance, but higher 15µA supply current and no 74HC4316 pin compatibility. | Better suited for high-speed, low-distortion applications (e.g., automated test equipment), but requires PCB redesign due to different pin assignment and larger 16-TSSOP package. | Choose ADG1414BRUZ only when sub-50ns switching and <2Ω RON are mandatory; retain MAX4537EEE for drop-in 74HC4316 replacement with proven field reliability. |
Compared with MAX4537ESE and ADG1414BRUZ, the MAX4537EEE uniquely balances pin compatibility, extended temperature support, ultra-low leakage, and QSOP packaging - making it optimal for cost-sensitive, space-constrained, and safety-critical analog multiplexing where exact 74HC4316 footprint reuse is required.

FAQ
What is the maximum supply voltage rating for MAX4537EEE?
The MAX4537EEE has an absolute maximum V+ to V− differential voltage of 13.0V. It operates safely within ±2V to ±6V dual supplies (12V total) or +2V to +12V single supply. Exceeding 13.0V - even momentarily due to overshoot or tolerance - risks permanent damage, so ±5% supplies must be verified for worst-case 13.2V compliance before deployment.
Does MAX4537EEE support rail-to-rail analog signals with single-supply operation?
Yes. When V− is tied to GND, the MAX4537EEE supports analog signals from 0V to V+ (e.g., 0V to +5V or 0V to +12V). Its internal CMOS switch architecture imposes no ground reference on the analog path, enabling true rail-to-rail conduction without distortion or clipping - confirmed across the full −40°C to +85°C range.
How does the enable (EN) pin interact with individual INx inputs on MAX4537EEE?
When EN is high, all four NC switches are forced open regardless of IN1–IN4 states. When EN is low, each INx controls its corresponding NC switch independently: INx = high opens that switch, INx = low keeps it closed. This two-level control enables both global shutdown and per-channel selection - a key feature distinguishing MAX4537EEE from basic 74HC4316 equivalents.
What is the guaranteed off-leakage current specification for MAX4537EEE at +85°C?
The MAX4537EEE guarantees ≤10nA maximum off-leakage current (ICOM_(OFF) and INO_(OFF)/INC_(OFF)) at +85°C, fully tested per production lot. This value is derived from correlation testing at +25°C and validated at hot temperature - ensuring predictable performance in extended-temperature industrial and avionics deployments where leakage-induced offset errors must remain below 10µV in 1MΩ circuits.
Is MAX4537EEE pin-compatible with the 74HC4316 in all package variants?
Yes. The MAX4537EEE in QSOP-16 matches the 74HC4316's pinout exactly: COM1–COM4, NC1–NC4, IN1–IN4, EN, GND, V−, and V+ occupy identical positions. This extends to MAX4537CSE (narrow SO) and MAX4537CPE (PDIP) - all share identical logic mapping and electrical interface, enabling direct substitution without layout changes.
