Product details
Overview
MAX392EPE+ from Maxim Integrated is a precision quad SPST analog switch with four normally open (NO) channels, designed for low-leakage signal routing in ±5V, +5V, or +3V systems. It delivers 60Ω max on-resistance at +5V, 130ns max turn-on time, <5pC charge injection, and operates across –40°C to +85°C - ideal for battery-powered test equipment and audio switching.
For engineers reviewing the MAX392EPE+ datasheet, MAX392EPE+ pinout, MAX392EPE+ application, or MAX392EPE+ equivalent, key selection criteria include guaranteed channel-to-channel RON match (<2Ω), ultra-low leakage (<100pA at +85°C), ESD robustness (>2000V), and compatibility with TTL/CMOS logic levels across single- or dual-supply configurations.
Technical Context
The MAX392EPE+ implements CMOS transmission-gate architecture with substrate tied to V+, enabling rail-to-rail analog signal handling from V– to V+. Its logic interface accepts standard TTL/CMOS thresholds (VINH = 2.4V, VINL = 0.8V) independent of supply voltage, supporting seamless integration into mixed-voltage systems.
All four switches operate simultaneously with matched timing: tON ≤130ns and tOFF ≤75ns under ±5V supplies, while maintaining <4Ω RON flatness over the full signal range - critical for precision sample-and-hold and DAC/ADC interface applications where gain error and distortion must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 60Ω max at +5V supply - ensures minimal signal attenuation and gain error in precision analog paths. |
| RON Match (ΔRON) | <2Ω max between channels - enables accurate differential signal routing and matched filter design. |
| Charge Injection | <5pC max - reduces sampling pedestal error in data acquisition and switched-capacitor circuits. |
| Off-Leakage Current | 100pA max at +85°C - preserves signal integrity in high-impedance sensor interfaces and long-hold sample-and-hold stages. |
| Supply Range | +3V to +15V single or ±3V to ±8V dual - supports flexible power architecture in portable and industrial systems. |
| ESD Rating | >2000V per Method 3015.7 - enhances reliability during board handling and system-level transient events. |
| Operating Temperature | –40°C to +85°C - qualified for extended industrial and automotive cabin environments. |
Pinout & Package
MAX392EPE+ uses a 16-pin plastic DIP (P16-1) package with through-hole mounting and 0.300" wide body. Pin 1 is top-left corner when notch faces up; exposed pad is absent (DIP variant).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Logic control inputs - active-high TTL/CMOS compatible; drive internal gate of respective NO switch. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path connection point for each switch channel. |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog outputs - connect to COM only when corresponding IN is high; isolated otherwise. |
| 4 | V– | Negative supply rail - required for dual-supply operation; sets lower analog signal limit (V– to V+). |
| 5 | GND | Ground reference - used as logic ground and return path for supply currents in single-supply mode. |
| 12 | N.C. | No internal connection - must remain unconnected; no electrical function or thermal role. |
| 13 | V+ | Positive supply rail - powers analog core and logic; also connected to substrate for ESD protection. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RON flatness | 4Ω max over full signal range - maintains consistent gain and linearity for ±3V signals under ±5V supplies. |
| Low power consumption | <1µW typical - enables multi-decade battery life in always-on portable instrumentation. |
| TTL/CMOS logic compatibility | Validated across full supply range (+3V to +15V) - eliminates level-shifter requirements in mixed-voltage designs. |
| Improved leakage over temperature | <2.5nA at +85°C - ensures stable offset and settling in high-precision DC-coupled signal chains. |
| Break-before-make timing | Not applicable - MAX392EPE+ is SPST NO only; no inter-channel switching sequence dependency. |
Applications
| Battery-Operated Test Equipment | Audio Signal Routing |
|---|---|
Use Scenario: Portable multimeter front-end multiplexing of voltage, current, and resistance measurement paths. IC Role / Device Role / Timing Role: Precision analog switch selecting input signal path to ADC while minimizing offset drift and crosstalk.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX392ESE+ | Same electrical specs, but in 16-pin narrow SOIC (S16-2) surface-mount package - 50% smaller footprint, no through-hole mounting. | Preferred for space-constrained PCBs and automated assembly; thermal performance differs due to package parasitics. | Select MAX392ESE+ when board real estate or reflow compatibility is prioritized over manual prototyping ease. |
| ADG1412BRUZ | Quad SPST, 1.5Ω typical RON, but higher 12pC charge injection and only rated to +125°C (not –40°C start); requires separate logic supply. | Better for ultra-low-RON precision instrumentation; unsuitable for low-leakage or wide-temperature battery systems. | Choose ADG1412BRUZ only if sub-2Ω matching and +125°C operation outweigh leakage and charge injection penalties. |
Compared with MAX392ESE+, the MAX392EPE+ offers identical analog performance but simplified hand-soldering and legacy DIP compatibility; versus ADG1412BRUZ, it trades lower RON for superior leakage, charge injection, and cold-temperature capability - making it optimal for portable, precision, and wide-temp embedded systems.

FAQ
What is the maximum analog signal range supported by the MAX392EPE+?
The MAX392EPE+ supports an analog signal range from V– to V+ across its COM, NO, and IN pins. With ±5V dual supplies, this spans –5V to +5V; with +5V single supply (V– = GND), the range is 0V to +5V. Absolute maximum ratings allow V– to –0.3V and V+ to +17V, but signal integrity is guaranteed only within the specified supply rails.
Does the MAX392EPE+ require power-supply sequencing?
Yes - proper sequencing is recommended: apply V+ first, then V–, then logic inputs. Violating this order risks exceeding absolute maximum ratings. If sequencing isn't feasible, external blocking diodes (as shown in Figure 1 of the datasheet) can be added to protect the MAX392EPE+, though they reduce the usable analog range by ~1V.
Can the MAX392EPE+ operate from a +3.3V single supply?
Yes - the MAX392EPE+ is fully specified for +3.0V to +3.6V operation. At +3.3V, typical RON rises to 120Ω (max 175Ω), tON increases to 400ns max, and leakage remains below 100pA at +85°C. All logic thresholds remain compatible with standard 3.3V CMOS drivers.
Is the exposed pad present on the MAX392EPE+ DIP package?
No - the MAX392EPE+ uses a standard 16-pin plastic DIP (P16-1) package without an exposed pad. Exposed-pad variants (e.g., MAX392EGE+) exist only in QFN packages. The DIP version relies on lead-frame conduction and ambient airflow for thermal management.
How does the MAX392EPE+ compare to the MAX391EPE+ in terms of switch configuration?
The MAX392EPE+ contains four normally open (NO) switches, meaning each channel connects COM to NO only when its IN pin is logic high. In contrast, the MAX391EPE+ has four normally closed (NC) switches - COM connects to NC when IN is logic low. Both share identical RON, leakage, timing, and supply specifications; only the default state differs.
