Product details
Overview
MAX4750EUD+ from Maxim Integrated is a dual single-pole/double-throw (SPDT) analog switch IC operating from a single +2V to +11V supply, delivering rail-to-rail signal handling with 50Ω max on-resistance at +3V, 3.5Ω max channel matching, and <0.1nA leakage at +25°C - ideal for precision low-power audio routing in portable medical devices and battery-powered instrumentation.
For engineers reviewing the MAX4750EUD+ datasheet, MAX4750EUD+ pinout, MAX4750EUD+ application, or MAX4750EUD+ equivalent, this page provides verified electrical specs, TSSOP-14 package layout, real-world use cases in glucose meters and communications circuits, and two validated alternative parts with documented functional and interface differences.
Technical Context
The MAX4750EUD+ implements two independent SPDT switches using CMOS process technology, each with break-before-make timing (1ns typ) to prevent signal shorting during state transitions. Its TTL/CMOS-compatible logic inputs accept rail-to-rail control voltages, enabling direct interfacing with microcontrollers across its full +2V to +11V supply range.
It supports bidirectional analog signal flow between COM, NO, and NC terminals with guaranteed flatness of ≤9Ω over the full signal range at +3V, and achieves -72dB off-isolation and -84dB crosstalk at 1MHz - critical for maintaining signal integrity in multi-channel AFEs and audio multiplexers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +11V - enables operation from single Li-ion cell up to industrial rails without level-shifting. |
| On-Resistance (RON) | 50Ω max at +3V - ensures minimal insertion loss and voltage drop in low-voltage sensor signal paths. |
| On-Resistance Matching | 3.5Ω max between channels at +3V - preserves gain and phase balance in differential or parallel-switched configurations. |
| Leakage Current | <0.1nA at TA = +25°C - prevents DC error accumulation in high-impedance measurement front-ends like glucose meter biosensors. |
| Off-Isolation | -72dB at 1MHz - suppresses coupling between inactive channels in audio/video routing applications. |
| Crosstalk | -84dB at 1MHz - maintains channel separation in multi-signal systems such as PDA audio codecs. |
| Turn-On/Off Time | 170ns / 70ns max at +3V - supports fast switching in data-acquisition sample-and-hold control. |
Pinout & Package
MAX4750EUD+ is housed in a 14-pin TSSOP package (JEDEC MO-153, 5.0mm × 4.4mm × 1.2mm), RoHS-compliant and lead-free, with exposed thermal pad not present in this variant (unlike TQFN-EP versions).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO1 | Normally open terminal of Switch 1 - connects to COM1 when IN1 is HIGH; used for signal path enable/disable. |
| 2 | COM1 | Common terminal of Switch 1 - bidirectional I/O node shared between NO1 and NC1; must be routed with controlled impedance. |
| 3 | NC1 | Normally closed terminal of Switch 1 - connects to COM1 when IN1 is LOW; provides default signal path in fail-safe configurations. |
| 4 | COM2 | Common terminal of Switch 2 - independent of COM1; enables dual-channel routing without cross-talk coupling. |
| 5 | NO2 | Normally open terminal of Switch 2 - activated by IN2; allows separate control of second analog path (e.g., stereo L/R selection). |
| 6 | NC2 | Normally closed terminal of Switch 2 - complements NO2 for complementary switching logic in communication circuitry. |
| 7 | GND | Digital/analog ground reference - must be connected to low-impedance system ground plane to minimize noise coupling. |
| 8 | IN1 | Logic input for Switch 1 - TTL/CMOS compatible; drives internal gate with rail-to-rail swing for lowest power consumption. |
| 9 | IN2 | Logic input for Switch 2 - electrically isolated from IN1; permits independent control of both SPDT sections. |
| 10 | N.C. | No connection - internally unconnected; PCB pad may be left floating or tied to GND for mechanical stability. |
| 11 | N.C. | No connection - same as Pin 10; no internal bond wire or circuitry attached. |
| 12 | N.C. | No connection - confirmed via Maxim's official pin description table for MAX4750EUD+ TSSOP variant. |
| 13 | V+ | Positive supply input - powers analog and digital sections; requires local 0.1µF bypass capacitor to GND per layout guidelines. |
| 14 | N.C. | No connection - final pin in TSSOP-14 footprint; unused and unconnected in MAX4750 die configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without clipping - essential for full-scale ADC input conditioning in low-voltage data acquisition. |
| Break-before-make switching | Guaranteed 1ns minimum interval prevents momentary shorting between NO and NC paths - required for safe signal reconfiguration in medical diagnostics. |
| Ultra-low quiescent power | 0.5nW typical supply current - extends battery life in always-on glucose meters and wearable health monitors. |
| Low charge injection (7pC) | Minimizes voltage glitch on sampled nodes - critical for precision integrator and sample-hold circuits in portable instrumentation. |
| 250MHz on-channel bandwidth | Preserves signal fidelity up to audio and baseband RF frequencies - suitable for HDMI auxiliary channel switching and VoIP codec interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4750ETE+ | Same die, 16-pin TQFN-EP (4mm × 4mm) with exposed pad tied to V+ - lower thermal resistance but requires different PCB footprint and reflow profile. | Better thermal performance in high-density layouts; unsuitable for legacy TSSOP footprints. | Select MAX4750ETE+ only if board space allows QFN and thermal management justifies redesign. |
| ADG736BRMZ | Dual SPDT, 5V-only supply (±1.8V to ±5.5V dual or +3.3V/+5V single), 4.5Ω RON at +5V, -80dB crosstalk - higher performance at 5V but incompatible below +2.5V. | Preferred for 5V industrial systems; cannot replace MAX4750EUD+ in 2.7–3.6V battery-powered designs. | Choose ADG736BRMZ for fixed 5V rails where lower RON and tighter matching outweigh supply flexibility needs. |
Compared with MAX4750ETE+, the MAX4750EUD+ offers drop-in compatibility with existing TSSOP-14 layouts and simplified thermal design, while ADG736BRMZ delivers superior analog performance at 5V but sacrifices the wide +2V to +11V single-supply operation critical for universal portable electronics.

FAQ
What is the maximum supply voltage rating for MAX4750EUD+?
The absolute maximum supply voltage (V+) for MAX4750EUD+ is +12V referenced to GND, but continuous operation is specified up to +11V. Exceeding +11V risks permanent damage and violates the device's guaranteed operating conditions. Always use a 0.1µF ceramic bypass capacitor close to the V+ and GND pins when operating near the upper limit.
Does MAX4750EUD+ support rail-to-rail analog signal switching?
Yes, MAX4750EUD+ supports true rail-to-rail analog signal switching - signals from GND to V+ pass through the switch with minimal distortion or RON variation. This is confirmed in the Electrical Characteristics tables and Typical Operating Characteristics plots (e.g., Figure TOC01), where RON remains stable across the full 0V to V+ range at all tested supply voltages.
What is the function of pins 10, 11, 12, and 14 on MAX4750EUD+?
Pins 10, 11, 12, and 14 on MAX4750EUD+ are all designated N.C. (No Connection) per Maxim's official pin description table. They have no internal bond wires or circuitry and may be left unconnected or tied to GND solely for mechanical PCB stability - no electrical function or signal routing should be assigned to these pins.
Can MAX4750EUD+ be used with a +2.5V supply?
Yes, MAX4750EUD+ is fully specified for operation down to +2.0V, including +2.5V. At +2.5V, on-resistance increases slightly (typical ~65Ω), but all key parameters - leakage, switching speed, and logic compatibility - remain within guaranteed limits. The device maintains TTL/CMOS compatibility when driven rail-to-rail (0V/2.5V).
Is MAX4750EUD+ pin-compatible with other parts in the MAX4747–MAX4750 family?
MAX4750EUD+ shares the same 14-pin TSSOP pinout with MAX4747EUD+, MAX4748EUD+, and MAX4749EUD+, but internal switch configuration differs: MAX4750EUD+ implements two SPDT switches (NO1/NC1/COM1 + NO2/NC2/COM2), whereas others implement quad SPST variants. Pin functions match only where signal type aligns (e.g., COM1, IN1, V+, GND); NO/NC assignments differ per part number.
