Product details
Overview
MAX392CAE from Maxim Integrated is a precision quad SPST analog switch with four normally open (NO) channels, designed for low-leakage signal routing in ±5V or single +3V/+5V systems. It delivers 30Ω max on-resistance, <5pC charge injection, 100pA max leakage at +25°C, and operates from -40°C to +85°C - ideal for battery-powered sample-and-hold circuits and ±5V DAC/ADC interfaces.
For engineers reviewing the MAX392CAE datasheet, MAX392CAE pinout, MAX392CAE application, or MAX392CAE equivalent, key selection criteria include guaranteed RON matching (<2Ω), RON flatness (≤4Ω), ESD robustness (>2000V), and dual/single-supply flexibility across industrial temperature range.
Technical Context
The MAX392CAE implements CMOS transmission-gate architecture with substrate tied to V+, enabling rail-to-rail analog signal switching from V− to V+. Its logic inputs are TTL/CMOS-compatible, and internal diode clamping protects terminals against overvoltage beyond absolute maximum ratings.
All four switches operate independently with break-before-make timing (5–10ns for MAX393 variant; not applicable to MAX392), while charge injection is tightly controlled (≤5pC) to minimize settling error in precision sampling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 30Ω max at ±5V supplies - ensures minimal signal attenuation and gain error in precision analog paths |
| RON Matching | <2Ω max between channels - critical for matched gain/attenuation in multi-channel instrumentation |
| Charge Injection | ≤5pC - limits voltage glitch on sampled hold capacitors, preserving ADC accuracy |
| Leakage Current | 100pA max at +25°C - maintains high-impedance node integrity in long-duration sample-and-hold |
| Supply Range | ±3V to ±8V dual or +3V to +15V single - supports legacy ±5V and modern low-voltage industrial systems |
| ESD Rating | >2000V per Method 3015.7 - enables robust handling in manufacturing and field deployment |
| Operating Temp | -40°C to +85°C - qualified for extended industrial environments without derating |
Pinout & Package
MAX392CAE is packaged in a 16-pin narrow SO (SOIC-N) with 150-mil body width (PKG code S16-2), lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16, 9, 8 | IN1–IN4 | Logic control inputs - active-high enables corresponding NO switch |
| 2, 15, 10, 7 | COM1–COM4 | Analog common terminals - connect to signal source or load in SPST configuration |
| 3, 14, 11, 6 | NO1–NO4 | Normally open switch outputs - conduct to COM only when IN = high |
| 4 | V− | Negative supply rail - must be connected for bipolar operation; sets lower analog signal limit |
| 5 | GND | Ground reference - used as return path in single-supply mode (V− = GND) |
| 12 | N.C. | No internal connection - must be left floating or tied to GND per layout best practice |
| 13 | V+ | Positive supply rail - powers switch core and logic; substrate tied to this pin |
Key Features
| Feature | Design Value |
|---|---|
| Quad NO topology | Four independent normally open switches - eliminates cross-conduction risk in multiplexed sensor or DAC output routing |
| RON flatness | ≤4Ω over full signal range - maintains consistent gain/attenuation across input voltage swing |
| Low power consumption | <1µW quiescent - extends battery life in portable test equipment and handheld meters |
| TTL/CMOS compatibility | VINH = 2.4V min, VINL = 0.8V max - interoperates directly with microcontrollers and FPGAs without level-shifting |
| Guaranteed leakage spec | <2.5nA at +85°C - validated across temperature for reliable long-term hold performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Quad SPST, 1.5Ω typical RON, but higher 12pC charge injection and no guaranteed RON match spec | Optimized for low-RON in high-speed data acquisition, less suited for precision sample-and-hold | Select ADG1412BRUZ only if sub-2Ω RON outweighs charge injection sensitivity |
| TS5A23157DGSR | Single-supply only (+1.65V to +5.5V), 0.9Ω RON, but 10nA leakage at +85°C and no bipolar support | Targeted at mobile consumer audio, not industrial ±5V systems requiring wide temp range | Choose TS5A23157DGSR for cost-sensitive, single-rail consumer designs - not for MAX392CAE's dual-supply use cases |
Compared with ADG1412BRUZ and TS5A23157DGSR, the MAX392CAE uniquely balances low leakage, tight RON matching, bipolar supply capability, and industrial temperature qualification - making it irreplaceable in precision ±5V data acquisition where signal integrity and long-term stability are non-negotiable.

FAQ
What is the maximum allowable analog signal range for MAX392CAE when operated from ±5V supplies?
The MAX392CAE supports an analog signal range from V− to V+, meaning ±5V supplies enable rail-to-rail switching from -5V to +5V. This is confirmed in the Electrical Characteristics table under "Analog Signal Range" for dual-supply conditions, and applies directly to the MAX392CAE variant. Exceeding these limits risks diode conduction and potential damage.
Does MAX392CAE support single-supply operation, and what are the key limitations?
Yes, MAX392CAE operates from a single +3V to +15V supply. At +5V, RON increases to 60Ω max (vs. 30Ω at ±5V), and analog range is 0V to +5V. Leakage remains ≤0.25nA, but charge injection stays ≤5pC. The device requires no external level shifters - TTL/CMOS inputs function directly.
How does the pinout of MAX392CAE differ from MAX391CAE and MAX393CAE?
MAX392CAE uses identical 16-pin SO package and pin mapping as MAX391CAE and MAX393CAE, but substitutes NC pins with NO pins: pins 3,6,11,14 are NO1–NO4 (not NC). This functional difference is reflected in the truth tables and top-view diagrams - all three share mechanical compatibility but differ in switch configuration (NO vs NC vs mixed).
Is the exposed pad (EP) present in the MAX392CAE package?
No - MAX392CAE is specified in the narrow SO (S16-2) package, which has no exposed pad. Exposed-pad variants (e.g., MAX392CGE) use QFN-EP packaging (G1655-3). The SO version relies on standard lead-frame thermal conduction; junction-to-ambient θJA is 8.70°C/mW per datasheet derating curve.
What is the guaranteed maximum on-resistance flatness for MAX392CAE, and why does it matter?
MAX392CAE guarantees ≤4Ω on-resistance flatness over its full analog signal range (V− to V+) under ±5V supplies. This means RON varies by no more than 4Ω as the switched signal sweeps across the rails - critical for maintaining linear gain in programmable-gain amplifiers or consistent attenuation in calibrated test equipment.
