Product details
Overview
MAX4537ESE 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 - enabling precision signal routing in battery-powered test equipment and avionics interfaces.
For engineers reviewing the MAX4537ESE datasheet, MAX4537ESE pinout, MAX4537ESE application, or MAX4537ESE equivalent, this page provides verified electrical parameters, package-confirmed pin functions, real-world use scenarios for NC-switched signal paths, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The MAX4537ESE implements four independent NC SPST switches sharing a single active-high 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 driven out-of-phase by level-translated control signals, enabling rail-to-rail analog conduction without ground reference.
Supply pins V+ and V− directly bias the analog switch transistors and define signal voltage limits; GND serves only digital logic and substrate reference. ESD protection (>2kV per Method 3015.7) is integrated on all analog and digital pins, with leakage current flowing exclusively to V+ or V− via reverse-biased diodes - not through GND or between channels.
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 systems with Li-ion or dual-rail power |
| On-Resistance | 200Ω max at +4.5V single supply - ensures minimal signal attenuation in audio and sensor signal paths |
| On-Resistance Match | 4Ω max between channels - critical for matched gain/attenuation in multi-channel instrumentation |
| 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 fast multiplexing in automated test equipment |
| Logic Compatibility | TTL/CMOS thresholds (0.8V low / 2.4V high at +5V) - interoperable with microcontrollers and FPGA I/O without level shifters |
Pinout & Package
MAX4537ESE is housed in a 16-pin narrow SO (Small Outline) package, 3.9mm × 9.9mm body, 1.27mm lead pitch, JEDEC MS-012 compliant. Pin 1 is top-left corner (notch side), pin count increases left-to-right, top row then bottom row.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 (COM1–COM4) | Analog common terminal for NC switches | Bi-directional signal path node - connects to source or load depending on system topology |
| 2, 3, 11, 12 (NC1–NC4) | Analog normally closed switch terminal | Conducts to COMx when EN = low; opens when EN = high - used for default-closed safety or standby paths |
| 5, 6, 14, 15 (IN1–IN4) | Digital control input per switch | Individual gate control (active-high); overridden by EN - enables per-channel or group switching |
| 7 (EN) | Global enable input | Active-high logic input - disables all switches (opens NC paths) when high, enables when low |
| 8 (GND) | Digital ground reference | Reference for logic inputs only; no analog signal return path - isolates digital noise from analog paths |
| 9 (V−) | Negative analog supply | Sets lower analog signal limit; connected to GND for single-supply operation |
| 16 (V+) | Positive analog/digital supply | Powers analog switches and internal logic; internally tied to substrate |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4316 | Direct drop-in replacement for legacy TTL-compatible analog switch designs - no PCB redesign required |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - eliminates clipping in ±5V or +10V data acquisition systems |
| Low power consumption | <1µW quiescent power - extends battery life in portable test gear and handheld avionics tools |
| ESD robustness | >2kV HBM per Method 3015.7 - withstands handling and board-level transients without latch-up |
| Break-before-make timing | Not applicable - MAX4537ESE is NC-only; break-before-make is exclusive to MAX4538 variant |
Applications
| Battery-Operated Test Equipment | Avionics Signal Routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4538ESE | Mixed NO/NC configuration (2×NO + 2×NC); includes break-before-make timing (125ns) on NC/NO pairs | Required where sequential switching (e.g., relay replacement) avoids transient shorts; unsuitable for pure NC-only use | Select MAX4538ESE only if mixed switch polarity and controlled transition timing are needed - not a direct substitute for NC-only function |
| ADG1414BRUZ | Quad SPST, NC; 1.5Ω typical RON, ±15V supply capable, but 32ns tON/20ns tOFF and higher 12µA supply current | Better performance in high-precision, wide-supply industrial DAQ; less suitable for battery life–constrained portable gear | Choose ADG1414BRUZ when sub-2Ω RON matching and ±15V range outweigh power and cost trade-offs |
Compared with MAX4537ESE, MAX4538ESE adds functional complexity unnecessary for NC-only routing, while ADG1414BRUZ trades ultra-low leakage and microwatt operation for higher speed and wider voltage range - making MAX4537ESE optimal for low-power, fail-safe, single-function analog switching.

FAQ
What is the operating temperature range for MAX4537ESE?
The MAX4537ESE is rated for –40°C to +85°C ambient operation, confirmed in the Ordering Information table and Absolute Maximum Ratings section. This extended industrial temperature grade makes MAX4537ESE suitable for avionics and outdoor test equipment where thermal cycling exceeds commercial-grade limits. All electrical specifications in the datasheet's "E" grade columns apply across this full range.
Does MAX4537ESE support single-supply operation?
Yes, MAX4537ESE operates from a +2V to +12V single supply when V− is connected to GND. The datasheet specifies performance under +5V and +3V single-supply conditions, including on-resistance (225Ω max at +4.5V), leakage (10nA max at +85°C), and switching times (100ns tON). Bipolar supply precautions (e.g., V+–V− ≤ 13.0V) still apply even in single-supply mode due to internal ESD diode structure.
How does the enable (EN) pin function on MAX4537ESE?
The EN pin on MAX4537ESE is an active-high global disable input: when EN = high, all four NC switches open regardless of IN1–IN4 states; when EN = low, each switch responds to its respective INx signal. This allows hierarchical control - e.g., system-level mute (EN) plus channel-specific routing (INx). The logic threshold is 0.8V low / 2.4V high at +5V supply, ensuring TTL/CMOS compatibility without external level shifting.
Is MAX4537ESE pin-compatible with the 74HC4316?
Yes, MAX4537ESE is explicitly stated as pin-compatible with the industry-standard 74HC4316 in the General Description. Both devices use identical 16-pin DIP/SO/QSOP footprints and share identical pin assignments for V+, GND, V−, EN, IN1–IN4, COM1–COM4, and NC1–NC4. This allows direct substitution in existing 74HC4316-based layouts without trace modifications.
What is the maximum allowable V+ to V− differential voltage for MAX4537ESE?
The absolute maximum V+ to V− differential voltage for MAX4537ESE is 13.0V, as specified in the Absolute Maximum Ratings table. Exceeding this - even momentarily due to supply overshoot or noise spikes - risks permanent damage. For example, ±6V supplies with ±10% tolerance reach 13.2V and must be derated; ±5V supplies are recommended for margin. This limit applies regardless of whether the device is used in dual- or single-supply configurations.
