Product details
Overview
MAX4591CUE+T from Maxim Integrated is a high-speed, quad SPST analog switch with normally closed (NC) configuration, designed for +12V or +15V single-supply operation. 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 audio/video switching systems.
For engineers reviewing the MAX4591CUE+T datasheet, MAX4591CUE+T pinout, MAX4591CUE+T application, or MAX4591CUE+T equivalent, this device is selected for low-leakage, fast-switching analog multiplexing where channel-to-channel RON matching (≤1Ω) and flatness (≤1.75Ω) are critical under industrial temperature conditions (0°C to +70°C).
Technical Context
The MAX4591CUE+T implements four independent NC SPST switches using CMOS process technology optimized for single-supply analog signal integrity. Its logic interface accepts TTL/CMOS-compatible inputs (0.8V/5V thresholds), and internal ESD protection exceeds 2000V per Method 3015.7.
All channels share a common V+ supply (up to +17V absolute max) and GND reference, with no negative rail required. Analog signal range spans V− to V+, where V− is tied to GND - supporting full-rail input signals up to 12V or 15V depending on supply configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 16Ω max at +12V supply - ensures minimal signal attenuation and gain error in precision instrumentation paths |
| On-Resistance Match | 1Ω max between channels - enables accurate differential or ratiometric measurements across switched paths |
| Turn-On / Turn-Off Time | 50ns / 30ns typical - supports high-speed sampling and multiplexing up to ~10MHz bandwidth |
| Charge Injection | 5pC max - reduces voltage glitch and settling time in sample-and-hold and ADC front-end circuits |
| Off-Leakage Current | 100pA max at +25°C - preserves signal integrity in high-impedance sensor interfaces and battery-powered systems |
| Analog Signal Range | 0V to V+ (up to +15V) - allows rail-to-rail analog signal handling without level-shifting circuitry |
| ESD Protection | >2000V per Method 3015.7 - enhances reliability in manufacturing, test, and field-deployed equipment |
Pinout & Package
MAX4591CUE+T is housed in a 16-pin TSSOP package (4.4mm × 5mm, 0.65mm pitch), optimized for space-constrained PCB layouts while maintaining thermal performance up to +70°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic control inputs | Drive ≥5V for "ON" (closed), ≤0.8V for "OFF" (open); TTL/CMOS compatible, high-impedance |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Signal path connection point shared with NC pins; must remain within V− to V+ range |
| NC1–NC4 (Pins 3, 6, 11, 14) | Normally closed analog terminals | Connected to COM when IN = low; open when IN = high - defines NC SPST topology |
| V+ (Pin 13) | Positive supply rail | +12V or +15V single supply; powers analog and logic sections; substrate tie |
| GND (Pin 5) | Ground reference | Common return for supply, logic, and analog paths; requires low-impedance PCB plane |
| V− (Pin 4) | Negative supply terminal | Internally tied to GND; not used as active rail but required for ESD diode biasing |
| N.C. (Pin 12) | No connection | Not bonded internally; must be left floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Quad NC SPST architecture | Four independent normally closed switches enable fail-safe signal routing in safety-critical or default-closed monitoring paths |
| Guaranteed RON flatness | 1.75Ω max over full signal range - maintains consistent gain and linearity across varying input voltages |
| Low-temperature leakage stability | 5nA max COM on-leakage at +85°C - ensures long-term accuracy in extended-temperature industrial environments |
| Pin compatibility with DG-series | Direct replacement for DG611/DG211 family - simplifies legacy system upgrades without layout changes |
| Break-before-make timing | Not applicable - MAX4591 is NC-only; no simultaneous conduction risk between channels |
Applications
| Test Equipment | Audio/Video Switching |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG611DN | Higher RON (35Ω typ), slower tON/tOFF (120ns/100ns), no guaranteed RON match or flatness spec | Limited to non-critical general-purpose switching; unsuitable for precision ratiometric or high-speed sampling | Select MAX4591CUE+T when channel matching, speed, or leakage specs are design-critical |
| MAX4592CUE+T | Identical package, timing, and leakage specs - but NO (normally open) configuration instead of NC | Used where default-open safety state is required (e.g., power-down isolation, fail-safe disconnect) | Choose MAX4591CUE+T for default-closed behavior; MAX4592CUE+T for default-open - same footprint, complementary function |
Compared with DG611DN and MAX4592CUE+T, the MAX4591CUE+T uniquely combines NC topology with guaranteed 1Ω RON matching and 5pC charge injection - making it the only option among the three for precision, fail-safe analog multiplexing in industrial test and military comms.

FAQ
What is the maximum supply voltage rating for MAX4591CUE+T?
The MAX4591CUE+T has an absolute maximum V+ rating of +17V. It is fully specified for reliable operation at +12V or +15V single-supply conditions. Exceeding +17V risks permanent damage, and operation below +12V may degrade RON, switching speed, and leakage performance per the datasheet limits. The MAX4591CUE+T must always have V− tied to GND.
Does MAX4591CUE+T support dual-supply operation?
No, the MAX4591CUE+T is designed exclusively for single-supply operation with V− connected to GND. It does not support true dual-supply (e.g., ±5V) configurations. For low-voltage or dual-supply analog switching, Maxim specifies the MAX391 series - not the MAX4591CUE+T - as the appropriate solution.
Is MAX4591CUE+T pin-compatible with DG611 devices?
Yes, the MAX4591CUE+T is explicitly pin-compatible with DG611, DG612, DG613, DG211, DG212, and DG213 devices in the same 16-pin TSSOP, SO, or DIP packages. This allows direct drop-in replacement without PCB redesign, though electrical performance (RON, speed, leakage) of the MAX4591CUE+T exceeds that of the DG-series parts.
What is the guaranteed on-resistance flatness specification for MAX4591CUE+T?
The MAX4591CUE+T guarantees ≤1.75Ω on-resistance flatness over the full analog signal range (0V to V+) when operated at +12V supply, and ≤1.5Ω at +15V supply. Flatness is defined as the difference between maximum and minimum RON measured across VCOM = 3V, 6V, and 9V - ensuring consistent signal gain regardless of input voltage level.
Can MAX4591CUE+T be used in automotive applications?
The MAX4591CUE+T is rated for 0°C to +70°C operation and is not qualified for automotive AEC-Q100 temperature grades (−40°C to +125°C). While its electrical specs meet many automotive signal-routing needs, its commercial-grade qualification means it lacks automotive-specific reliability testing and documentation - use MAX4591EUE+T (−40°C to +85°C) for automotive-qualified alternatives.
