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 systems.
For engineers reviewing the MAX4537ESE+ datasheet, MAX4537ESE+ pinout, MAX4537ESE+ application, or MAX4537ESE+ equivalent, this page provides verified specifications, package-validated pin functions, real-world use scenarios for audio-signal routing and low-voltage data acquisition, and two confirmed alternative parts with documented technical and application 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 by level-translated gate signals referenced to V+ and V−, enabling true rail-to-rail analog conduction without ground reference.
ESD protection exceeds 2kV per Method 3015.7, and leakage paths are dominated by reverse-biased ESD diodes between each analog pin and V+/V− - resulting in temperature-dependent off-leakage (10nA max at +85°C) and supply-current draw under signal bias, not digital control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports portable and industrial rails without level-shifting |
| On-Resistance (RON) | 200Ω max at +4.5V single supply - ensures minimal signal attenuation in 50Ω–600Ω systems |
| RON Matching | 4Ω max between channels - critical for matched gain/phase in multi-path signal conditioning |
| 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 sub-10MHz multiplexing with controlled timing skew |
| Rail-to-Rail Operation | Analog range spans V− to V+ - allows full-scale signal switching without clipping in bipolar systems |
| Logic Compatibility | 0.8V/2.4V thresholds at +5V supply - interoperates directly with TTL and CMOS controllers |
Pinout & Package
MAX4537ESE+ is housed in a 16-pin narrow SOIC (Small Outline Integrated Circuit) package, 3.9mm wide, with standard JEDEC MS-012AC footprint and 1.27mm pitch. Pin 1 is marked with a beveled corner or dot; device orientation follows industry-standard SOIC conventions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives P-channel gates and powers internal logic; substrate-connected |
| V− | Negative analog supply | Drives N-channel gates; tied to GND for single-supply operation |
| GND | Digital ground reference | No analog current path; only logic-level reference and ESD return |
| EN | Active-high enable input | High disables all four NC switches simultaneously; TTL/CMOS compatible |
| IN1–IN4 | Individual switch control inputs | Each controls one NC switch; overridden when EN = high |
| COM1–COM4 | Common terminals (NC configuration) | Analog I/O pins; bidirectional, no polarity constraint |
| NC1–NC4 | Normally closed switch terminals | Connected to COM when INx = low; open when INx = high or EN = high |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4316 | Direct drop-in replacement in legacy designs using industry-standard 16-pin layout |
| Low power consumption | <1µW quiescent - extends battery life in portable test and avionics equipment |
| Rail-to-rail signal handling | VCOM, VNC swing from V− to V+ - eliminates external biasing in ±5V systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4537EEE+ | Same electrical specs; QSOP-16 package (3.9mm × 4.9mm vs. SOIC-16's 3.9mm × 9.9mm) | Preferred for space-constrained PCBs where thermal mass and trace length matter less than footprint | Select MAX4537EEE+ when board area is limited and reflow profile supports smaller body size |
| ADG1414BRUZ | Quad SPST, but NO configuration only; 1.5Ω RON max, −40°C to +125°C rating, higher supply voltage limit (+36V) | Suitable for industrial PLC I/O modules requiring wider voltage range and extended temp, but lacks NC functionality | Choose ADG1414BRUZ only if NC behavior is unnecessary and 125°C operation or >±6V supplies are required |
Compared with MAX4537ESE+, MAX4537EEE+ offers identical performance in a smaller QSOP package, while ADG1414BRUZ trades NC functionality for lower on-resistance and extended temperature/voltage capability - making it unsuitable as a direct functional replacement but viable for NO-only designs needing higher ruggedness.

FAQ
What is the operating temperature range of the MAX4537ESE+?
The MAX4537ESE+ is rated for −40°C to +85°C operation, validated across its full electrical specification range. This extended industrial temperature grade makes it suitable for deployment in avionics, portable test gear, and outdoor instrumentation where ambient conditions exceed commercial limits. All key parameters - including on-resistance, leakage, and switching time - are guaranteed across this range per the official Maxim datasheet revision.
Does the MAX4537ESE+ support single-supply operation?
Yes, the MAX4537ESE+ supports single-supply operation from +2V to +12V, with V− connected to GND. In this mode, analog signals swing from 0V to V+, and logic thresholds remain TTL/CMOS-compatible at +5V. The device maintains 200Ω max on-resistance and 1nA max off-leakage at +25°C, though RON increases at lower voltages (e.g., 600Ω at +3V), as confirmed in the +3V single-supply electrical characteristics table.
How does the enable (EN) pin function on the MAX4537ESE+?
The EN pin on the 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 individually to its corresponding INx input. This architecture allows synchronized channel shutdown for power saving or safety-critical isolation - a feature explicitly defined in the truth tables and functional diagrams of the MAX4537ESE+ datasheet.
Is the MAX4537ESE+ pin-compatible with the 74HC4316?
Yes, the MAX4537ESE+ is fully pin-compatible with the industry-standard 74HC4316 in 16-pin SOIC, DIP, and QSOP packages. Pin assignments for V+, V−, GND, EN, IN1–IN4, COM1–COM4, and NC1–NC4 match the 74HC4316 layout exactly - enabling direct substitution without PCB modification. This compatibility is explicitly stated in the "General Description" section and verified in the pin configuration diagrams of the MAX4537ESE+ datasheet.
What is the maximum allowable supply voltage differential for the MAX4537ESE+?
The absolute maximum V+ to V− differential for the MAX4537ESE+ is 13.0V, as specified in the Absolute Maximum Ratings table. Exceeding this - even momentarily due to tolerance stack-up (e.g., ±6V supplies with ±10% tolerance yielding 13.2V) - risks permanent damage. Designers must ensure supply rails comply strictly with this limit; for ±6V operation, use regulated supplies with ≤±5% tolerance or include overvoltage clamping.
