Product details
Overview
MAX4618EUE+T from Analog Devices is a high-speed, low-voltage CMOS dual 4-channel analog multiplexer configured for bidirectional signal routing in compact TSSOP-16 packaging. It operates from a single +2V to +5.5V supply, delivers 15ns turn-on time and 10ns turn-off time at +5V, maintains ≤10Ω on-resistance (max) and <0.017% THD at 600Ω - enabling precision audio/video switching and low-voltage data acquisition.
For engineers reviewing the MAX4618EUE+T datasheet, MAX4618EUE+T pinout, MAX4618EUE+T application, or MAX4618EUE+T equivalent, this device is selected for rail-to-rail analog handling, TTL/CMOS logic compatibility at +5V, guaranteed channel-to-channel on-resistance match (≤1Ω), and -96dB crosstalk in battery-powered instrumentation and communications circuits.
Technical Context
The MAX4618EUE+T implements two independent 4:1 analog multiplexers sharing common address lines (A, B) and a global ENABLE input. Each mux supports bidirectional signal flow with rail-to-rail analog voltage range (0V to VCC) and features break-before-make switching with ≤1.5ns transition time.
Its BiCMOS process ensures low leakage (1nA off-leakage at +25°C), low charge injection (3pC), and stable on-resistance flatness (≤1Ω) across the full analog signal range - critical for maintaining signal integrity in multi-channel sampling systems and analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V single supply - enables direct integration into 3.3V and 5V systems without level-shifting. |
| Turn-On / Turn-Off Time | 15ns / 10ns (VCC = +5V) - supports >20MHz digital control rates and fast channel switching in real-time signal routing. |
| On-Resistance (max) | 10Ω at +5V, 20Ω at +3V - ensures minimal gain error and voltage drop in precision sensor or DAC output paths. |
| Off-Leakage Current | 1nA at +25°C, 10nA at +85°C - preserves accuracy in high-impedance measurement nodes and battery-critical standby modes. |
| Crosstalk / Off-Isolation | -96dB / -93dB at 100kHz - suppresses inter-channel interference in multi-signal A/V routing and simultaneous sampling applications. |
| THD | <0.017% (600Ω load, 20Hz–20kHz) - meets fidelity requirements for professional audio signal path switching. |
| Logic Thresholds | 0.8V low / 2.4V high at +5V - guarantees robust TTL/CMOS compatibility without external biasing. |
Pinout & Package
MAX4618EUE+T is housed in a 16-pin TSSOP package (JEDEC MO-153, 4.4mm × 5mm body, 0.65mm pitch) with exposed pad for thermal enhancement. Pin 1 marked by dot; pin 1 is top-left corner when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 2, 4 | X0–X3 analog inputs | Four independent "X-side" analog inputs for first 4:1 mux section. |
| 3 | X analog output | Common output node for X-side multiplexer; bidirectional signal path. |
| 12, 14, 15, 11 | Y0–Y3 analog inputs | Four independent "Y-side" analog inputs for second 4:1 mux section. |
| 13 | Y analog output | Common output node for Y-side multiplexer; fully independent of X-path. |
| 6 | ENABLE | Active-high global enable; drives all switches open when high - essential for power-gating and fault isolation. |
| 7 | N.C. | No internal connection - must be left floating or grounded per layout best practice. |
| 8 | GND | Analog/digital ground reference; requires low-impedance connection to minimize noise coupling. |
| 9, 10 | A, B | Binary address inputs selecting one of four channels per mux - shared between X and Y sections. |
| 16 | VCC | Positive supply for analog switch core and digital logic - must be decoupled locally with 0.1µF ceramic capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible replacement | Direct drop-in for 74HC4052 and MAX4582 - eliminates PCB redesign in legacy analog routing upgrades. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4582EUE+ | Same pinout, identical function, but rated only for 0°C to +70°C; lower production volume post-2020. | Suitable for commercial-grade consumer electronics; not qualified for extended industrial temperature range. | Select MAX4618EUE+T when -40°C to +85°C operation or long-term supply continuity is required. |
| 74HC4052PW,118 | Pin-compatible but higher on-resistance (120Ω typ at +4.5V); no guaranteed RON match or THD spec. | Acceptable for digital signal routing or non-critical analog paths; unsuitable for precision measurement or audio. | Choose MAX4618EUE+T where ≤10Ω RON, <0.017% THD, or guaranteed channel matching is mandatory. |

FAQ
What is the maximum analog signal voltage range supported by the MAX4618EUE+T?
The MAX4618EUE+T supports rail-to-rail analog signals from 0V to VCC. When powered from a +5V supply, the analog input/output range is 0V to +5V; at +3.3V supply, it is 0V to +3.3V. This capability enables direct interfacing with sensors, DACs, and ADCs without external level-shifting circuitry in single-supply systems.
Does the MAX4618EUE+T require separate analog and digital ground planes?
No - the MAX4618EUE+T uses a single GND pin (Pin 8) for both analog and digital functions. However, proper PCB layout requires a low-impedance, star-connected ground plane with local 0.1µF decoupling at Pin 16 (VCC) and careful separation of noisy digital traces from sensitive analog signal paths to maintain -96dB crosstalk performance.
Can the MAX4618EUE+T operate from a +2.5V supply, and what performance trade-offs occur?
Yes, the MAX4618EUE+T operates from +2.5V, but on-resistance increases to 30–60Ω (typ), and switching times extend to ~12ns. The device remains functional with rail-to-rail signal handling and 1nA leakage, making it viable for ultra-low-power applications where speed and RON are secondary to supply voltage reduction.
Is the MAX4618EUE+T pin-compatible with the MAX4582, and are there any layout considerations?
Yes - the MAX4618EUE+T is fully pin-compatible with the MAX4582 in TSSOP-16 packaging, including identical pin functions and footprint. No PCB changes are required for migration; however, verify that the ENABLE logic polarity and thermal pad grounding match design intent, as both devices share identical thermal and electrical pin mappings.
What is the guaranteed on-resistance match between channels of the MAX4618EUE+T, and why does it matter?
The MAX4618EUE+T guarantees ≤1Ω on-resistance match between any two channels at +5V supply. This tight matching ensures consistent gain, attenuation, and time constants across multiplexed paths - critical for ratiometric measurements, differential signal conditioning, and calibrated sensor arrays where channel-to-channel gain error must be minimized.
