Product details
Overview
MAX4514EUK-TG05 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 in battery-powered and portable systems. It operates from a single +2V to +12V supply, delivers 20Ω on-resistance at +5V, supports ≤1nA off-leakage at +25°C, and switches audio/video signals with 150ns turn-on time - deployed in cellular phones and PCMCIA cards.
For engineers reviewing the MAX4514EUK-TG05 datasheet, MAX4514EUK-TG05 pinout, MAX4514EUK-TG05 application, or MAX4514EUK-TG05 equivalent, key selection criteria include guaranteed on-resistance flatness (≤3Ω), break-before-make timing (tON > tOFF), TTL/CMOS logic compatibility at +5V, and SOT23-5 package suitability for space-constrained PCB layouts.
Technical Context
The MAX4514EUK-TG05 implements a CMOS transmission-gate architecture with dual ESD diodes per analog terminal (to V+ and GND), enabling rail-to-rail analog signal handling up to ±0.3V beyond supply rails. Its digital control interface uses fixed 0.8V/2.4V logic thresholds at +5V, independent of V+ variation.
Switching behavior is defined by voltage-controlled gate drive derived from V+ and GND; no external bias is required. Charge injection is tightly controlled at 10pC (typ), minimizing transient glitches in precision data-acquisition paths, while off-isolation exceeds -90dB at 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V and 5V systems without level shifters |
| On-Resistance (RON) | 20Ω max at +5V - ensures minimal signal attenuation and distortion in audio routing paths |
| Off-Leakage Current | 1nA max at +25°C - preserves battery life and accuracy in high-impedance sensor front-ends |
| Switching Speed | tON = 150ns, tOFF = 100ns - supports fast multiplexing in data-acquisition and modem signal paths |
| Charge Injection | 10pC max - limits voltage glitch on switched nodes, critical for ADC sample-and-hold integrity |
| Analog Signal Range | Rail-to-rail (0V to V+) - allows full utilization of supply headroom in low-voltage portable designs |
| Logic Compatibility | 0.8V/2.4V thresholds at +5V - guarantees reliable switching with standard TTL/CMOS microcontroller GPIO |
Pinout & Package
SOT23-5 surface-mount package (3.099mm × 1.499mm × 1.397mm), rated for -40°C to +85°C operation, with exposed pad not internally connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NO | Normally Open analog terminal | Signal path only conducts when IN = HIGH; electrically identical to NC/COM for bidirectional routing |
| 2 - IN | Digital control input | Active-HIGH logic input; drives internal gate with V+ referenced threshold (2.4V min at +5V) |
| 3 - GND | Ground reference | Common return for analog and digital circuitry; substrate tied internally to V+ |
| 4 - V+ | Positive supply | Powers analog switch core and logic translator; sets analog voltage limits and ESD clamp reference |
| 5 - COM | Common analog terminal | Bidirectional signal hub; connects to NO when enabled, isolated otherwise; interchangeable with NO/NC |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make timing | tON > tOFF at +5V prevents momentary short-circuits during channel switching in multiplexer arrays |
| Low on-resistance flatness | ≤3Ω variation across 0–3.5V analog range - maintains consistent gain and THD in audio signal chains |
| Guaranteed leakage specs | 100% tested at +85°C; correlated to +25°C - ensures reliability in extended-temperature industrial deployments |
| ESD robustness | >2000V per Method 3015.7 - reduces need for external protection in handheld device interfaces |
| Small-footprint packaging | SOT23-5 footprint (3.1mm × 1.5mm) - saves board area in space-constrained cellular phone baseband modules |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4514CUK+T | Same silicon, 0°C to +70°C temp grade, identical pinout and electrical specs | Not qualified for automotive or industrial ambient extremes; unsuitable for outdoor or under-hood use | Select MAX4514EUK-TG05 when operation beyond +70°C or below 0°C is required |
| ADG801BRMZ-REEL7 | 2.5Ω RON at +3V, 0.5pC charge injection, but only +1.8V to +5.5V supply range | Lacks +12V capability and rail-to-rail performance above 3.3V; limited to ultra-low-voltage portable designs | Choose ADG801BRMZ-REEL7 only if sub-3V operation and ultra-low glitch energy are mandatory |
Compared with MAX4514CUK+T, MAX4514EUK-TG05 extends temperature coverage to -40°C to +85°C without sacrificing RON, leakage, or speed; versus ADG801BRMZ-REEL7, it trades lower on-resistance for broader supply flexibility and higher voltage tolerance essential in mixed-signal telecom equipment.

FAQ
What is the operating temperature range of the MAX4514EUK-TG05?
The MAX4514EUK-TG05 is specified for continuous operation from -40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official datasheet, making it suitable for deployment in automotive infotainment modules and outdoor portable instrumentation where ambient conditions exceed commercial-grade limits.
Does the MAX4514EUK-TG05 support rail-to-rail analog signal switching?
Yes, the MAX4514EUK-TG05 supports rail-to-rail analog signal switching - its analog terminals (NO, NC, COM) handle signals from GND to V+ without clipping. This is explicitly stated in the General Description and verified in the Electrical Characteristics tables, where Analog Signal Range is listed as 0V to V+ across all supply voltages (+2V to +12V).
Is the MAX4514EUK-TG05 pin-compatible with the MAX4515 series?
No, the MAX4514EUK-TG05 is not pin-compatible with MAX4515 variants. While both share the SOT23-5 package and identical pin numbering, their functional states differ: MAX4514EUK-TG05 is normally open (NO), whereas MAX4515 is normally closed (NC). Swapping them requires logic inversion and may cause system malfunction unless firmware compensates for inverted enable polarity.
What is the maximum allowable analog signal voltage relative to V+ for the MAX4514EUK-TG05?
The MAX4514EUK-TG05 permits analog signals up to (V+ + 0.3V) or down to -0.3V relative to GND, per Absolute Maximum Ratings. This tolerance arises from internal ESD diodes clamping signals to V+ and GND; exceeding these limits risks forward-biasing those diodes and drawing excessive current (>±20mA), potentially damaging the device.
Can the MAX4514EUK-TG05 be used with a +3.3V supply?
Yes, the MAX4514EUK-TG05 operates reliably with a +3.3V supply. The datasheet includes dedicated Electrical Characteristics tables for +3V supply conditions, specifying 50Ω max on-resistance and 150ns turn-on time. Logic thresholds remain compatible, as the 0.8V/2.4V inputs function correctly across the full +2V to +12V range.
