Product details
Overview
MAX4651EUE-T from Maxim Integrated is a quad, normally closed (NC), single-pole single-throw (SPST) CMOS analog switch operating from a single +1.8V to +5.5V supply. It delivers 4Ω maximum on-resistance at +5V, 0.2Ω max on-resistance matching between channels, and rail-to-rail analog signal handling up to V+. Designed for low-distortion signal routing, it replaces mechanical relays in automated test equipment and battery-powered data-acquisition systems.
For engineers reviewing the MAX4651EUE-T datasheet, MAX4651EUE-T pinout, MAX4651EUE-T application, or MAX4651EUE-T equivalent, key selection criteria include verified NC configuration, 16-pin TSSOP package compatibility, sub-20ns switching speed, <0.1nA off-leakage at +25°C, and guaranteed 0.8Ω on-resistance flatness over the full signal range.
Technical Context
The MAX4651EUE-T implements four independent SPST switches with normally closed logic behavior: each switch conducts when its INx input is logic low (0), and opens when high (1). Its CMOS architecture supports rail-to-rail analog signals from GND to V+, with internal protection diodes clamping inputs beyond supply rails.
All four switches share a common +1.8V to +5.5V single supply (V+), require TTL/CMOS-compatible control inputs (VIH = 2.4V min at 5V, VIH = 2.0V min at 3V), and exhibit matched dynamic performance - tON = 11ns typ / 14ns max, tOFF = 6ns typ / 8ns max (at +5V, RL = 300Ω, CL = 35pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 4Ω max at +5V - ensures minimal voltage drop and power loss in signal paths carrying up to ±50mA continuous current. |
| On-resistance matching | 0.2Ω max across channels - enables precise gain/phase tracking in multi-channel instrumentation and sampling circuits. |
| On-resistance flatness | 0.8Ω max over 0V to V+ signal range - maintains consistent attenuation and linearity for audio, video, and sensor signals. |
| Off-leakage current | 0.1nA max at +25°C - preserves signal integrity in high-impedance sample-and-hold and precision measurement nodes. |
| Switching time (tON/tOFF) | 11ns/6ns typ at +5V - supports high-speed multiplexing in data-acquisition systems up to ~30MHz effective bandwidth. |
| Crosstalk | -100dB at 1MHz - prevents coupling-induced interference between adjacent switched analog channels. |
| Supply voltage range | +1.8V to +5.5V - enables direct integration into 1.8V, 3.3V, and 5V logic domains without level-shifting circuitry. |
Pinout & Package
MAX4651EUE-T is housed in a 16-pin TSSOP package (4.4mm × 5.0mm, 0.65mm pitch) with exposed pad not implemented. Pin functions are fully defined per Maxim's official pin description table and match the MAX4651 family's standardized layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Active-low logic: switch closes (NC path conductive) when input = 0V; opens when ≥2.4V (at +5V supply). |
| COM1–COM4 | Analog common terminals | Signal entry points shared with NC paths; must remain within GND–V+ during operation. |
| NC1–NC4 | Normally closed analog terminals | Conductive path to COMx when corresponding INx = 0; open-circuit when INx = 1. |
| V+ | Positive supply input | Single bias rail powering all switches and logic; requires local 0.1µF bypass to GND. |
| GND | Ground reference | Return path for supply current and analog signal reference; must be low-impedance. |
| N.C. | No-connect pins | Pins 3, 6, 11, 14 - unconnected internally; may be left floating or tied to GND for mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs from GND to V+ without clipping - essential for full-scale sensor and audio signal routing. |
| Low on-resistance flatness | 0.8Ω max variation across entire signal range - minimizes harmonic distortion (<0.02% THD) in AC-coupled paths. |
| TTL/CMOS logic compatibility | VIH = 2.4V min, VIL = 0.8V max at +5V - interfaces directly with FPGA I/O, microcontroller GPIO, and standard logic families. |
| Ultra-low off-leakage | 0.1nA max at +25°C - enables accurate DC-coupled measurements in high-Z front-ends and long-hold sample-and-hold circuits. |
| Fast switching | tON = 11ns typ, tOFF = 6ns typ - allows time-multiplexed sampling of multiple sensors with minimal channel skew. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4652EUE-T | Quad NO (normally open) configuration vs. MAX4651EUE-T's NC - logic polarity inverted; identical RON, timing, and supply specs. | Suitable where default-open safety state is required (e.g., power-off signal isolation), but not drop-in for NC-driven control firmware. | Select MAX4652EUE-T only if system logic expects active-high enable; otherwise, firmware or external inverters needed. |
| ADG1412BRUZ | 4.5Ω RON max at +5V, 16-TSSOP, but requires dual ±5V or single +12V supply - no 1.8V operation; higher 10nA leakage. | Targeted at industrial PLC I/O modules needing higher breakdown voltage (>±20V signal range), not low-voltage portable designs. | Choose ADG1412BRUZ only when >±15V signal swing or higher ESD robustness (±4kV HBM) is mandatory; not suitable for battery operation. |
Compared with MAX4651EUE-T, MAX4652EUE-T offers identical performance in a complementary logic configuration requiring firmware adaptation, while ADG1412BRUZ trades low-voltage operation and ultra-low leakage for higher voltage tolerance - making MAX4651EUE-T the optimal choice for 1.8V–5.5V portable and precision measurement systems.

FAQ
What is the logic configuration of the MAX4651EUE-T?
The MAX4651EUE-T features four normally closed (NC) SPST analog switches. Each switch conducts (connects COMx to NCx) when its corresponding digital input (IN1–IN4) is logic low (≤0.8V), and opens (disconnects) when the input is logic high (≥2.4V at +5V supply). This behavior is confirmed in the truth tables and pin diagrams of the official Maxim datasheet Rev 2.
Does the MAX4651EUE-T support rail-to-rail analog signals?
Yes, the MAX4651EUE-T supports rail-to-rail analog signals from GND to V+, as explicitly stated in the General Description and Detailed Description sections. Its CMOS switch architecture allows analog voltages equal to the supply rails without clipping or increased distortion - a key requirement validated in THD and RON flatness specifications.
What is the maximum operating supply voltage for the MAX4651EUE-T?
The MAX4651EUE-T has an absolute maximum V+ rating of +6V, but its specified operational range is +1.8V to +5.5V. Electrical characteristics including RON, leakage, and timing are guaranteed across this full range - with typical RON = 4Ω at +5V and RON = 7Ω max at +3V, per the datasheet's Electrical Characteristics tables.
Is the MAX4651EUE-T pin-compatible with other packages in the MAX4651 family?
Yes, the MAX4651EUE-T (16-pin TSSOP) shares identical pin numbering and function mapping with the MAX4651EGE (16-pin QFN) and MAX4651ESE (16-pin SO), as confirmed in the Pin Description table and Pin Configurations section. All three packages use the same 1–16 pinout order for IN1, COM1, NC1, N.C., GND, etc., enabling direct PCB footprint interchangeability.
What is the off-isolation performance of the MAX4651EUE-T?
The MAX4651EUE-T provides −75dB off-isolation at 1MHz, measured as 20log₁₀(VCOM/VNO) with RL = 50Ω and CL = 5pF. This value is specified in the Electrical Characteristics table and reflects signal rejection from a powered-off switch path - critical for preventing crosstalk in multi-channel routing applications.
