Product details
Overview
MAX4537EPE 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 MAX4537EPE datasheet, MAX4537EPE pinout, MAX4537EPE application, or MAX4537EPE 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 MAX4537EPE implements four independent NC analog switches driven by CMOS logic-level translators that convert TTL/CMOS-compatible inputs (0.8V–2.4V thresholds at +5V supply) into full-rail gate drive signals for matched N- and P-channel MOSFETs. Its internal architecture includes reverse-biased ESD diodes between each analog pin and both V+ and V−, defining leakage behavior and limiting analog signal range to V− ≤ VCOM/VNC ≤ V+.
Switch timing is supply-dependent: tON = 100ns and tOFF = 80ns at ±4.5V, with break-before-make operation excluded (MAX4538 only). Charge injection is specified at 1pC typical, and off-isolation reaches −65dB at 1MHz, supporting high-fidelity audio and data acquisition where crosstalk and signal integrity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports legacy ±5V systems and modern low-voltage portable designs |
| On-Resistance (RON) | 200Ω max at +4.5V single supply - ensures minimal signal attenuation in 50Ω–600Ω impedance paths |
| RON Matching | 4Ω max difference between channels - preserves gain/phase balance across multi-channel routing |
| Off-Leakage Current | 1nA max at +25°C - enables accurate DC-coupled measurements in high-impedance sensor front-ends |
| Signal Range | Rail-to-rail (V− to V+) - allows full-swing analog signals without clipping in bipolar or single-supply configurations |
| Logic Compatibility | TTL/CMOS thresholds (0.8V low / 2.4V high at +5V) - eliminates level-shifting in mixed-voltage control planes |
| Turn-On/Turn-Off Time | 100ns / 80ns at ±4.5V - supports multiplexing of audio and medium-speed data up to ~5MHz bandwidth |
Pinout & Package
MAX4537EPE is supplied in a 16-pin plastic DIP (dual in-line package) with 0.300-inch body width and 0.100-inch lead pitch, rated for −40°C to +85°C industrial temperature operation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | COM1–COM4 | Common terminals for NC switches - bidirectional analog path endpoints, referenced to V+ and V− |
| 2, 3, 11, 12 | NC1–NC4 | Normally closed switch terminals - conduct to COM when INx = low; open when INx = high or EN = high |
| 5, 6, 14, 15 | IN1–IN4 | Digital control inputs per switch - active-low logic for individual NC path enable/disable |
| 7 | EN | Global enable - logic high disables all four NC switches simultaneously (open state) |
| 8 | GND | Digital ground reference - no analog current return path; isolated from analog signal domain |
| 9 | V− | Negative analog supply - sets lower bound of analog signal range; connected to GND for single-supply use |
| 16 | V+ | Positive analog/digital supply - powers internal logic translators and switch FETs; internally tied to substrate |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4316 | Direct drop-in replacement for legacy quad SPST logic-controlled switches in existing PCB layouts |
| Rail-to-rail signal handling | Supports full dynamic range analog signals from V− to V+, eliminating external biasing in ±5V or +3.3V systems |
| Low charge injection (1pC typ) | Minimizes voltage glitches at switch nodes - critical for sample-and-hold and precision DAC output buffering |
| ESD protection >2kV (HBM) | Robust handling during board assembly and field service without additional external protection components |
| Ultra-low power consumption (<1µW) | Negligible impact on battery life in portable instrumentation and handheld test gear |

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 electrical specs and logic behavior; 16-pin narrow SO package (3.9mm width) instead of 16-pin PDIP | Preferred for space-constrained PCBs and automated SMT assembly; thermal resistance differs (696mW vs. 842mW PDIP) | Select MAX4537ESE when footprint density or reflow compatibility is prioritized over through-hole prototyping flexibility. |
| ADG1434BRUZ | Quad SPST NC switch with 4.7Ω RON max (at ±15V), higher supply range (±5V to ±16.5V), but no 2V min operation or 1nA leakage spec | Better suited for high-voltage industrial PLC I/O modules; not suitable for sub-3V battery operation or ultra-low-leakage sensor muxing | Choose ADG1434BRUZ only when system requires >±12V operation and can tolerate higher RON mismatch and leakage. |
Compared with MAX4537ESE, the MAX4537EPE offers identical switching performance in a through-hole package ideal for lab validation and low-volume production; versus ADG1434BRUZ, it delivers superior low-voltage operation and leakage control but lacks extended high-voltage capability.

FAQ
What is the maximum allowable V+ to V− differential voltage for MAX4537EPE?
The absolute maximum V+ to V− differential voltage for MAX4537EPE is 13.0V. Exceeding this rating - even momentarily due to supply overshoot or noise spikes - risks permanent damage. At ±6V nominal supplies (12V differential), ensure ±5% tolerance or tighter to stay within limit; ±5% 12V supplies may reach 12.6V, leaving only 0.4V margin.
Does MAX4537EPE support single-supply operation below +3V?
Yes, MAX4537EPE supports single-supply operation down to +2.0V. Electrical characteristics are guaranteed at +2.7V to +3.6V (3V supply range), with on-resistance rising to 600Ω max and turn-off time extending to 250ns at +2.7V - confirmed in the +3V Single Supply section of the datasheet.
How does the EN pin interact with individual INx controls on MAX4537EPE?
On MAX4537EPE, the EN pin acts as a global override: when EN = high, all four NC switches are forced open regardless of IN1–IN4 states. When EN = low, each switch responds independently to its corresponding INx input (low = closed, high = open), enabling both group disable and per-channel control.
Is MAX4537EPE pin-compatible with the 74HC4316 in all package variants?
Yes, MAX4537EPE (16-pin PDIP) is fully pin-compatible with the industry-standard 74HC4316 in the same 16-pin DIP package. Pin functions, spacing, and numbering match exactly - allowing direct substitution without layout changes, though logic polarity (NC vs NO) and supply voltage range differ.
What is the guaranteed off-leakage current specification for MAX4537EPE at +85°C?
The guaranteed maximum off-leakage current for MAX4537EPE at +85°C is 10nA, as specified in the Electrical Characteristics table under "ICOM_(OFF)" and "INO_(OFF)/INC_(OFF)" for both dual and single supply conditions - tested at maximum rated hot temperature and correlated at +25°C.
