Product details
Overview
The MAX4514EUK-T from Maxim Integrated is a single-pole/single-throw (SPST), normally-open (NO), CMOS analog switch optimized for low-voltage, rail-to-rail signal routing. It operates from a single +2V to +12V supply, delivers 20Ω on-resistance at +5V, supports ≤1nA off-leakage at +25°C, and switches in 150ns turn-on time-ideal for battery-powered audio routing and low-voltage data acquisition.
For engineers reviewing the MAX4514EUK-T datasheet, MAX4514EUK-T pinout, MAX4514EUK-T application, or MAX4514EUK-T equivalent, key selection criteria include guaranteed on-resistance flatness (≤3Ω), charge injection (10pC), break-before-make timing (tON > tOFF), TTL/CMOS logic compatibility at +5V, and SOT23-5 packaging for space-constrained PCBs.
Technical Context
The MAX4514EUK-T implements a CMOS transmission-gate architecture with dual-channel ESD protection diodes tied to V+ and GND on all analog pins. Its control logic includes level translators that convert 0.8V–2.4V input thresholds into full-rail gate drive, enabling robust switching across the entire +2V to +12V supply range.
Signal integrity is maintained via matched P/N transistor sizing to minimize on-resistance variation over voltage and temperature, while internal charge-balanced topology limits charge injection to 10pC-critical for precision sample-and-hold and multiplexer applications where signal settling error must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply - enables direct integration with Li-ion, 3.3V, and 5V systems without level-shifting. |
| On-Resistance (RON) | 20Ω max at +5V - ensures minimal signal attenuation and gain error in sensor front-ends and audio paths. |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance measurement circuits (e.g., pH sensors, thermocouples). |
| Charge Injection | 10pC - limits voltage glitch on sampled nodes, supporting ≤12-bit accuracy in ADC multiplexing. |
| Switching Speed | tON = 150ns, tOFF = 100ns - suitable for multiplexing up to ~1MHz sampling rates with clean channel transitions. |
| Logic Thresholds | 0.8V to 2.4V at +5V supply - guarantees reliable TTL/CMOS compatibility without external biasing. |
| Analog Signal Range | Rail-to-rail (0V to V+) - allows full-swing AC/DC signal pass-through without clipping or distortion. |
Pinout & Package
SOT23-5 package: compact 2.9mm × 1.6mm footprint with 0.95mm pitch; thermally enhanced for low-power operation in portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NO | Normally Open analog terminal | Open-circuit path when IN = LOW; connects to COM only when switch is enabled. |
| 2 - IN | Digital control input | Active-HIGH logic input; drives internal level translator to enable/disable the switch. |
| 3 - GND | Analog and digital ground reference | Common return for all analog signals and logic circuitry; must be low-impedance. |
| 4 - V+ | Positive supply rail | Powers analog switch core and digital logic; sets maximum analog signal swing (0V to V+). |
| 5 - COM | Common analog terminal | Shared node for bidirectional signal routing between NO and COM; interchangeable as input or output. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | tON > tOFF at +5V prevents momentary shorting during channel transitions-essential for safe multiplexer sequencing. |
| Guaranteed RON flatness | ≤3Ω over full analog range - maintains consistent gain and linearity across varying signal amplitudes. |
| Low on-leakage current | 2nA max at +25°C - avoids DC offset drift in precision instrumentation amplifiers and integrators. |
| ESD-protected analog pins | ±2000V per Method 3015.7 - eliminates need for external TVS diodes in handheld and field-deployable equipment. |
| Temperature-rated performance | -40°C to +85°C operating range - validated for automotive cabin modules and industrial edge sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4514CUK | Same electrical specs but rated for 0°C to +70°C - lacks extended temperature validation. | Not qualified for automotive or industrial ambient environments above +70°C. | Select MAX4514EUK-T when operation beyond +70°C is required; otherwise MAX4514CUK offers cost advantage. |
| ADG801BRM | Lower RON (0.3Ω typ), but higher 25nA off-leakage at +85°C and no guaranteed 1nA spec at +25°C. | Better for ultra-low-loss RF/IF paths; less suitable for high-Z sensor multiplexing requiring sub-nA leakage. | Choose ADG801BRM for <1Ω RON priority; choose MAX4514EUK-T when leakage-limited precision dominates design. |
Compared with MAX4514CUK, the MAX4514EUK-T adds guaranteed -40°C to +85°C operation and tighter leakage specs; versus ADG801BRM, it trades lower RON for significantly lower leakage and broader supply flexibility (+2V to +12V vs. +1.8V to +5.5V), making it more versatile in mixed-supply embedded systems.

FAQ
What is the maximum supply voltage rating for the MAX4514EUK-T?
The MAX4514EUK-T has an absolute maximum supply voltage of +13V, but its specified operational range is +2V to +12V. Operating at +12V yields optimal on-resistance (10Ω typical), while staying within datasheet limits ensures reliability and longevity. Exceeding +13V risks permanent damage due to internal ESD diode breakdown.
Does the MAX4514EUK-T support bidirectional analog signal flow?
Yes, the MAX4514EUK-T supports fully bidirectional signal routing between the NO and COM terminals. Its CMOS transmission-gate structure imposes no directionality-voltage, current, and frequency characteristics are identical regardless of signal direction, enabling flexible use in both input and output signal paths.
What is the guaranteed on-resistance flatness specification for the MAX4514EUK-T?
The MAX4514EUK-T guarantees on-resistance flatness (∆RON) of ≤3Ω over the full analog signal range (0V to V+) and across the -40°C to +85°C temperature range. This tight flatness ensures minimal harmonic distortion and consistent gain in audio and precision measurement applications.
Can the MAX4514EUK-T be used with a +3.3V logic supply while powered from +5V?
No-the MAX4514EUK-T logic inputs are referenced to its own V+ supply. Driving IN with +3.3V logic while V+ = +5V violates the 0.8V–2.4V threshold window and may cause undefined switching behavior. For mixed-supply systems, use level translation or match logic supply to V+.
Is the SOT23-5 package of the MAX4514EUK-T RoHS-compliant and lead-free?
Yes, the MAX4514EUK-T in SOT23-5 packaging is RoHS-compliant and lead-free per Maxim's standard manufacturing process. The device carries the "-T" suffix indicating tape-and-reel packaging and full environmental compliance, verified per JEDEC J-STD-609 and IPC/JEDEC J-STD-020 standards.
