Product details
Overview
MAX4537EEE/GH9 from Maxim Integrated is a quad, low-voltage, normally closed (NC) SPST analog switch with common enable, operating from ±2V to ±6V dual supplies 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. It is used in audio-signal routing and low-voltage data acquisition systems where precise analog path control and low leakage are critical.
For engineers reviewing the MAX4537EEE/GH9 datasheet, MAX4537EEE/GH9 pinout, MAX4537EEE/GH9 application, or MAX4537EEE/GH9 equivalent, this page provides verified electrical parameters, QSOP-16 package details, truth-table–validated switching behavior, TTL/CMOS-compatible logic thresholds, and real-world substitution guidance for industrial and portable equipment designs.
Technical Context
The MAX4537EEE/GH9 implements four independent NC SPST switches sharing a single active-low enable (EN) input - all switches open when EN = high, close when EN = low. Its CMOS transmission-gate architecture uses complementary N- and P-channel MOSFETs driven by level-shifted logic to support rail-to-rail analog signals across V+ and V−.
Internal ESD protection (>2kV per Method 3015.7) and reverse-biased diodes between each analog pin and both supplies define leakage paths; off-leakage is specified at 10nA max at +85°C. Switch timing is supply-dependent: tON = 100ns and tOFF = 80ns typical at ±4.5V, with break-before-make only applicable to MAX4538 - not present in MAX4537.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports battery-powered and mixed-supply systems without level shifters. |
| On-Resistance (RON) | 200Ω max at +25°C - ensures minimal signal attenuation and gain error in precision sensor or audio paths. |
| RON Matching | 4Ω max between channels - enables matched gain/attenuation in multi-channel instrumentation or balanced signal routing. |
| Off-Leakage Current | 10nA max at +85°C - preserves accuracy in high-impedance sensor front-ends and battery-critical standby modes. |
| Logic Thresholds | VINL ≤ 1.4V, VINH ≥ 1.4V - guarantees reliable TTL/CMOS compatibility with +5V or ±5V supplies. |
| Turn-On/Off Time | tON = 100ns, tOFF = 80ns at ±4.5V - suitable for multiplexing up to ~5MHz analog signals with minimal settling distortion. |
| Analog Signal Range | Rail-to-rail (V− to V+) - allows full utilization of supply headroom in single-ended or bipolar signal chains. |
Pinout & Package
MAX4537EEE/GH9 is housed in a 16-pin QSOP (Quarter Small Outline Package) with 0.635 mm pitch, 3.99 mm × 4.98 mm body, and 1.27 mm max height - optimized for space-constrained portable and avionics PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 (COM1–COM4) | Analog common terminal for NC switches | Each COM connects bidirectionally to its paired NC pin; no internal polarity - usable as input or output. |
| 2, 3, 11, 12 (NC1–NC4) | Normally closed analog switch terminal | Path closed when INx = low and EN = low; opens when either INx or EN goes high - true NC behavior per channel. |
| 5, 6, 14, 15 (IN1–IN4) | Individual channel logic control inputs | Directly drive respective NC switch gate logic; independent of EN but overridden when EN = high. |
| 7 (EN) | Global enable (active-low) | High disables all four switches regardless of INx states - enables system-level power gating or safety interlock. |
| 8 (GND) | Digital ground reference | Reference for logic inputs only; no analog current path - must be tied to system digital ground, not analog ground. |
| 9 (V−) | Negative analog supply | Set to GND for single-supply operation; defines lower bound of analog signal range and P-MOSFET gate drive. |
| 16 (V+) | Positive analog/digital supply | Powers internal logic translators and N/P-MOSFET gates; internally connected to substrate - requires stable decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4316 | Direct drop-in replacement for legacy HC logic-controlled analog switches - no PCB redesign required. |
| Rail-to-rail signal handling | Supports analog signals spanning full V− to V+ range - eliminates clipping in ±5V or +3.3V data acquisition front-ends. |
| Low 1nA off-leakage at +25°C | Minimizes voltage error in high-Z sensor interfaces (e.g., thermocouples, pH electrodes) and extends battery life in standby. |
| TTL/CMOS logic compatibility | Operates reliably with standard 5V microcontroller GPIO or FPGA I/O without external level-shifting circuitry. |
| ESD robustness >2kV (HBM) | Withstands handling and board-level ESD events - reduces field failure risk in test equipment and portable diagnostics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4537ESE | Same die, identical specs, but in 16-pin narrow SO package (5.00 mm × 4.00 mm) - 0.65 mm pitch, taller profile (1.75 mm). | SO package offers higher thermal mass and easier rework than QSOP; less space-efficient for ultra-compact layouts. | Select MAX4537ESE if board assembly uses SO-reflow processes or requires higher power dissipation margin. |
| ADG1434BRUZ | Quad SPST NC switch with 4.7Ω RON, ±15V supply capability, and 1pC charge injection - significantly lower RON but higher cost and larger 20-pin TSSOP package. | Targeted at high-precision, wide-supply industrial DAQ; not pin-compatible and requires layout change. | Choose ADG1434BRUZ only when sub-5Ω RON and <2pC charge injection are mandatory - not a drop-in substitute. |
Compared with MAX4537ESE, MAX4537EEE/GH9 offers identical electrical performance in a smaller QSOP footprint ideal for portable designs; versus ADG1434BRUZ, it trades higher RON for lower cost, smaller size, and proven compatibility with 74HC4316-based legacy systems.

FAQ
What is the operating temperature range for MAX4537EEE/GH9?
The MAX4537EEE/GH9 is rated for -40°C to +85°C operation, confirmed by its "E" grade suffix and ordering information table listing MAX4537EEE under -40°C to +85°C temperature range. This extended industrial grade makes it suitable for avionics, outdoor test gear, and automotive cabin electronics where ambient temperatures exceed commercial limits. All electrical specifications in the datasheet - including leakage, RON, and timing - are guaranteed across this full range.
Is MAX4537EEE/GH9 pin-compatible with the 74HC4316?
Yes, MAX4537EEE/GH9 is explicitly stated as pin-compatible with the industry-standard 74HC4316 in the General Description section. Its QSOP-16 pinout matches the 74HC4316's function-to-pin mapping for COM, NC/NO, IN, EN, V+, V−, and GND - enabling direct replacement in existing designs without layout changes. This compatibility extends to logic thresholds, supply ranges, and switching behavior under identical conditions.
Does MAX4537EEE/GH9 support break-before-make switching?
No, MAX4537EEE/GH9 does not implement break-before-make (BBM) functionality. BBM is exclusive to the MAX4538 variant (which combines two NO and two NC switches), as confirmed in the Truth Tables and Electrical Characteristics tables where tBBM is only specified for MAX4538. The MAX4537 operates as four independent NC switches - each transitions directly between closed and open states without intentional dead time.
What is the maximum supply voltage differential for MAX4537EEE/GH9?
The absolute maximum V+ to V− differential for MAX4537EEE/GH9 is 13.0V, as specified in the Absolute Maximum Ratings table. Exceeding this - even momentarily due to overshoot or noise - risks permanent damage. For example, ±6V supplies (12V total) are acceptable, but ±6.6V (13.2V) exceeds the limit. Designers must verify supply tolerances and transient margins, especially with ±5% or ±10% regulated rails.
Can MAX4537EEE/GH9 operate from a single +3.3V supply?
Yes, MAX4537EEE/GH9 supports single-supply operation from +2.0V to +12V, including +3.3V. The Electrical Characteristics table confirms operation at +3V supply (V+ = 2.7V to 3.6V), with RON = 600Ω max and tON/tOFF = 300ns/250ns typical. Logic thresholds scale accordingly (VINL = 0.5V, VINH = 2.0V), ensuring compatibility with 3.3V CMOS I/O. Analog signal range remains rail-to-rail (0V to +3.3V).
