Product details
Overview
The MAX4591CPE from Maxim Integrated is a high-speed, quad, normally closed (NC) SPST analog switch operating on a single +12V or +15V supply. It delivers 16Ω max on-resistance, ≤80ns turn-on time, ≤45ns turn-off time, 5pC max charge injection, and 100pA max off-leakage - enabling precision signal routing in test equipment and guidance systems.
For engineers reviewing the MAX4591CPE datasheet, MAX4591CPE pinout, MAX4591CPE application, or MAX4591CPE equivalent, this device supports critical design requirements including channel-to-channel RON matching (≤1Ω), RON flatness (≤1.75Ω), ESD protection (>2000V), and logic-level compatibility with TTL/CMOS inputs.
Technical Context
The MAX4591CPE implements four independent NC analog switches using CMOS process technology optimized for low leakage and fast switching. Its internal architecture ensures guaranteed RON match and flatness over the full analog signal range (0V to V+), with input logic thresholds compatible with standard 5V TTL/CMOS drivers.
It operates exclusively from a single positive supply (V+ = +12V or +15V); no negative rail is required. The device features integrated ESD protection diodes and clamping structures that limit analog terminal voltages to within V− and V+, supporting robust operation in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 16Ω max at +15V supply - ensures minimal signal attenuation and voltage drop across switched paths |
| On-Resistance Match | 1Ω max between channels - enables precise gain-matching in multi-channel instrumentation |
| Charge Injection | 5pC max - reduces sampling error in sample-and-hold circuits and ADC front-ends |
| Turn-On / Turn-Off Time | tON ≤80ns, tOFF ≤45ns - supports high-speed multiplexing up to ~10MHz bandwidth |
| Off-Leakage Current | 100pA max at +25°C - preserves accuracy in high-impedance sensor interfaces and precision integrators |
| ESD Protection | >2000V per Method 3015.7 - provides reliable handling and board-level robustness without external protection |
| Analog Signal Range | 0V to V+ - allows rail-to-rail analog signal switching with no headroom loss |
Pinout & Package
MAX4591CPE is housed in a 16-pin plastic DIP package (0.3-inch width), suitable for through-hole prototyping and legacy industrial PCBs. Pin numbering follows standard DIP orientation with Pin 1 at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Digital control inputs | Accept 0.8V/5V logic levels; drive corresponding NC switches open/closed |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Signal path inputs shared with NC terminals; connect to source signals |
| NC1–NC4 (Pins 3, 6, 11, 14) | Normally closed analog outputs | Connected to COM when IN = 0; disconnected when IN = 1 (logic high) |
| V+ (Pin 13) | Positive supply rail | Single +12V or +15V supply; powers analog and digital sections |
| GND (Pin 5) | Ground reference | Common return for supply and logic; must be low-impedance for noise immunity |
| V− (Pin 4) | Negative supply terminal | Internally tied to GND; must be connected to ground for proper operation |
| N.C. (Pin 12) | No connection | Not bonded internally; leave unconnected on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Quad NC configuration | Four independent normally closed switches simplify fail-safe signal routing in safety-critical systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4591EPE | Same electrical specs but rated for -40°C to +85°C industrial temperature range | Suitable for extended-temperature embedded systems where ambient exceeds +70°C | Select MAX4591EPE for automotive or outdoor industrial deployments requiring wider thermal margin |
| DG611DN | Pin-compatible but higher RON (45Ω typ), slower switching (tON = 120ns), and no guaranteed RON match | Acceptable for non-critical general-purpose switching where precision matching is not required | Choose DG611DN only if cost sensitivity outweighs performance requirements for leakage, speed, and matching |
Compared with MAX4591EPE, the MAX4591CPE trades extended temperature capability for lower cost and tighter initial calibration tolerance at 0°C to +70°C; versus DG611DN, it delivers superior precision, speed, and ESD robustness - making it preferred for test, military, and high-fidelity signal-path designs.

FAQ
What is the maximum supply voltage rating for the MAX4591CPE?
The MAX4591CPE has an absolute maximum V+ rating of +17V, but it is fully specified for reliable operation at +12V or +15V single-supply conditions. Operation above +15V is not guaranteed and may degrade RON, leakage, or lifetime reliability. Always observe the recommended operating range of 12V to 15V for the MAX4591CPE to maintain datasheet performance.
Does the MAX4591CPE require a negative supply voltage?
No, the MAX4591CPE operates from a single positive supply only. Pin 4 (V−) must be connected to ground (GND), as it is not a functional negative rail but a reference terminal tied internally to substrate. Using the MAX4591CPE with V− left floating or biased negatively violates absolute maximum ratings and risks latch-up or permanent damage.
Is the MAX4591CPE pin-compatible with older industry-standard analog switches?
Yes, the MAX4591CPE is explicitly pin-compatible with the DG611/DG612/DG613 and DG211/DG212/DG213 families in 16-pin DIP packages. This allows direct replacement in existing layouts without PCB modification, provided system-level parameters - especially RON, leakage, and switching speed - meet updated design requirements for the MAX4591CPE.
What is the guaranteed on-resistance flatness specification for the MAX4591CPE at +12V supply?
At +12V supply, the MAX4591CPE guarantees ≤1.75Ω on-resistance flatness (RFLAT(ON)) over the full analog signal range. This means the difference between maximum and minimum RON measured at VCOM = 3V, 6V, and 9V remains within 1.75Ω - critical for maintaining linearity in precision gain-setting and signal routing applications using the MAX4591CPE.
How does the MAX4591CPE handle electrostatic discharge (ESD)?
The MAX4591CPE provides >2000V human-body-model ESD protection per Method 3015.7 on all pins, including analog and digital terminals. This level of protection is built-in and does not require external TVS diodes for typical handling and board-level stress. However, system-level ESD events exceeding 2kV still warrant appropriate PCB layout practices - such as guarding and grounding - to preserve MAX4591CPE performance in end-use environments.
