Product details
Overview
MAX4593CSE+ from Maxim Integrated is a high-speed, precision quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, designed for +12V or +15V single-supply operation. It delivers 16Ω max on-resistance, ≤50ns turn-on time, ≤30ns turn-off time, 5pC max charge injection, and 1.75Ω max RON flatness - enabling precise signal routing in test equipment and guidance systems.
For engineers reviewing the MAX4593CSE+ datasheet, MAX4593CSE+ pinout, MAX4593CSE+ application, or MAX4593CSE+ equivalent, key selection criteria include guaranteed channel-to-channel RON match (≤1Ω), low leakage (≤0.1nA at +25°C), ESD robustness (>2000V), and compatibility with DG611/DG612/DG613 and DG211/DG212/DG213 footprints.
Technical Context
The MAX4593CSE+ implements CMOS-based SPST switching architecture with break-before-make timing (5–20ns) confirmed for its dual-logic-configured channels (IN1/IN4 control NC switches; IN2/IN3 control NO switches). Its analog signal range spans V− to V+, supporting rail-to-rail operation when V− = GND.
It features internal clamping diodes on all analog terminals (COM, NO, NC), enabling overvoltage protection up to ±0.3V beyond supply rails. Supply current remains ultra-low (≤1µA) across temperature, and logic inputs accept standard TTL/CMOS thresholds (VINH ≥ 5V, VINL ≤ 0.8V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 16Ω max at +15V supply - ensures minimal signal attenuation and gain error in precision instrumentation paths. |
| Turn-On / Turn-Off Time | tON ≤ 50ns, tOFF ≤ 30ns - supports high-speed multiplexing in data acquisition and ATE systems up to ~10MHz. |
| RON Match Between Channels | ≤1Ω max - enables matched gain/attenuation across differential or multi-channel signal paths without calibration. |
| Charge Injection | ≤5pC - minimizes voltage glitch on sample-and-hold capacitors, critical for 12-bit+ ADC front-ends. |
| Off-Leakage Current | ≤0.1nA at +25°C - preserves accuracy in high-impedance sensor interfaces and long-time-constant integrators. |
| ESD Rating | >2000V per Method 3015.7 - provides robust handling margin during board assembly and field service. |
| Analog Signal Range | V− to V+ - supports rail-to-rail analog signals with V− = GND and V+ = +12V or +15V. |
Pinout & Package
MAX4593CSE+ is housed in a 16-pin narrow SO (SOIC) package, 3.9mm wide, with standard 1.27mm pitch and gull-wing leads. Pin 1 is marked by a beveled corner or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3, IN4 (Pins 1, 8, 9, 16) | Digital control inputs | Accept TTL/CMOS logic levels; IN1/IN4 drive NC switches, IN2/IN3 drive NO switches. |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Signal input/output nodes shared between NO and NC paths per channel. |
| NO1, NO2 (Pins 3, 14) | Normally open analog outputs | Connect to COMx only when corresponding INx = logic high (active). |
| NC1, NC2 (Pins 6, 11) | Normally closed analog outputs | Connect to COMx when corresponding INx = logic low (default state). |
| V+ (Pin 13) | Positive supply rail | +12V or +15V single supply; powers analog and logic sections; must be sequenced first. |
| V− (Pin 4) | Negative supply rail | Typically tied to GND; defines lower analog signal limit and substrate bias. |
| GND (Pin 5) | Ground reference | Logic and analog return path; separate grounding from noisy digital planes improves crosstalk performance. |
| N.C. (Pin 12) | No connection | Internally unconnected; must remain floating - no external tie or pull-up/down. |
Key Features
| Feature | Design Value |
|---|---|
| Two NO + two NC configuration | Enables mixed-signal routing in fault-tolerant or redundant architectures - e.g., active path + backup path selection. |
| Break-before-make timing | 5–20ns guaranteed interval prevents momentary shorting between NO and NC paths during transition. |
| RON flatness ≤1.75Ω | Maintains consistent gain/attenuation across full analog signal range (0–10V), critical for linear signal conditioning. |
| Low off-isolation degradation | 72dB off-isolation at 10MHz ensures minimal crosstalk between adjacent channels in high-frequency multiplexers. |
| Pin compatibility with DG6xx/DG2xx series | Allows drop-in replacement in legacy designs using Vishay Siliconix analog switches without PCB redesign. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4592CSE+ | Four NO-only channels; identical RON, speed, leakage, and package - differs only in switch logic polarity. | Suitable where all four paths require active-high enable; not usable where NC functionality is required for default-state safety. | Select MAX4592CSE+ only if system design mandates uniform NO behavior across all channels. |
| DG612DN-T1-E3 | 16-pin TSSOP; 20Ω RON max; 75ns tON; no guaranteed RON match or flatness spec; ESD rated to 2000V HBM. | Functional alternative for cost-sensitive industrial controls; lacks precision specs needed for metrology-grade test gear. | Choose DG612DN-T1-E3 when absolute RON matching and sub-50ns timing are non-critical. |
Compared with MAX4592CSE+, the MAX4593CSE+ adds NC capability essential for fail-safe routing, while DG612DN-T1-E3 trades precision for broader availability and lower unit cost - making MAX4593CSE+ optimal for applications demanding both reliability and signal integrity.

FAQ
What is the maximum supply voltage rating for MAX4593CSE+?
The MAX4593CSE+ has an absolute maximum positive supply rating of +17V (V+ to GND), but it is fully specified for reliable operation at +12V or +15V. Operation outside the recommended +12V/+15V range may degrade RON, switching speed, or leakage performance. The MAX4593CSE+ must never be operated with V+ below −0.3V or above +17V to avoid permanent damage.
Does MAX4593CSE+ support rail-to-rail analog signal switching?
Yes, the MAX4593CSE+ supports rail-to-rail analog signal switching when V− = GND and V+ = +12V or +15V - its analog signal range is specified from V− to V+. This allows full utilization of the supply rails for input signals, provided external clamping or sequencing protects against overvoltage transients exceeding ±0.3V beyond V+ or V−.
How does the dual NO/NC configuration of MAX4593CSE+ improve system reliability?
The MAX4593CSE+ integrates two NO and two NC switches to enable fail-safe signal path selection - for example, an NC channel can maintain default connectivity during power-up or fault conditions, while the NO channel activates only upon command. This architecture eliminates reliance on external pull resistors or auxiliary logic, reducing component count and improving MTBF in guidance and military radio systems where MAX4593CSE+ is deployed.
Is MAX4593CSE+ pin-compatible with older industry-standard analog switches?
Yes, the MAX4593CSE+ is explicitly pin-compatible with the DG611/DG612/DG613 and DG211/DG212/DG213 families in 16-pin SO and TSSOP packages. This allows direct substitution in existing layouts without PCB modification - though designers must verify logic polarity mapping (e.g., IN1/IN4 control NC paths on MAX4593CSE+, unlike uniform NO behavior on DG612).
What is the guaranteed on-resistance flatness specification for MAX4593CSE+ at +12V supply?
At +12V supply, the MAX4593CSE+ guarantees ≤1.75Ω on-resistance flatness (RFLAT(ON)) over the full analog signal range (VCOM = 3V, 6V, 9V), measured with ICOM = −10mA. This tight flatness ensures minimal gain variation across the signal swing - critical for linearity in audio routing, video switching, and precision instrumentation where MAX4593CSE+ is commonly applied.
