Product details
Overview
The MAX4618CUE from Analog Devices is a high-speed, low-voltage CMOS dual 4-channel analog multiplexer operating from a single +2V to +5.5V supply. It features 15ns turn-on time, 10ns turn-off time, 10Ω max on-resistance at +5V, rail-to-rail signal handling, and TTL/CMOS-compatible logic thresholds - enabling precise audio/video signal routing in battery-powered instrumentation.
For engineers reviewing the MAX4618CUE datasheet, MAX4618CUE pinout, MAX4618CUE application, or MAX4618CUE equivalent, key selection criteria include guaranteed on-resistance matching (≤1Ω), low off-leakage (1nA at +25°C), high off-isolation (–93dB), and pin compatibility with 74HC4052 and MAX4582 for drop-in replacement in legacy designs.
Technical Context
The MAX4618CUE integrates two independent 4-channel analog multiplexers sharing common address lines (A, B) and a global ENABLE input. Each 4:1 section routes one of four bidirectional analog inputs (X0–X3 or Y0–Y3) to its respective output (X or Y) under digital control, with break-before-make switching to prevent signal shorting during transitions.
Its BiCMOS process ensures stable on-resistance over temperature and supply voltage, while internal ESD diodes clamp analog inputs to VCC/GND. Logic thresholds scale with VCC (e.g., 2.4V high threshold at +5V; 2.0V at +3V), supporting mixed-supply system interfacing without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V single supply - supports direct integration into 3.3V and 5V systems without regulators |
| Turn-On Time (tON) | 15ns max at +5V - enables high-speed data acquisition sampling up to ~33 MHz effective rate |
| On-Resistance (RON) | 10Ω max at +5V, 20Ω max at +3V - minimizes signal attenuation and gain error in precision sensor interfaces |
| On-Resistance Match | ≤1Ω between channels at +5V - ensures consistent channel-to-channel gain in multi-path signal conditioning |
| Off-Isolation | –93dB at 100kHz - suppresses crosstalk between inactive channels in dense A/V routing applications |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance, low-current circuits like pH sensors or photodiode amplifiers |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V at +5V) - eliminates need for external level translation when driven by microcontrollers or FPGAs |
Pinout & Package
MAX4618CUE is housed in a 16-pin TSSOP package (lead-free/RoHS-compliant, + symbol), 4.4mm × 5mm footprint, 0.65mm pitch, suitable for compact PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 2, 4 | X0–X3 analog inputs | Four bidirectional analog terminals for first 4:1 multiplexer section; interchangeable as input or output |
| 3 | X analog output | Common output node for X0–X3 selection; supports rail-to-rail signal swing |

| 13 | Y analog output | Common output node for Y0–Y3 selection; electrically isolated from X section |
| 11, 10, 9 | A, B, C address inputs | Digital select lines (C not used in MAX4618); A/B control both X and Y sections simultaneously |
| 6 | ENABLE | Active-low global enable; pulls all switches open when high - enables power-gating of unused sections |
| 7 | N.C. | No internal connection - must be left unconnected or tied to GND for mechanical stability |
| 8 | GND | Analog/digital ground reference; shared return for all signals and supplies |
| 16 | VCC | Positive supply for analog switches and logic core; sets analog signal range limits (0V to VCC) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full VCC-to-GND signal range without clipping - essential for audio line-level and sensor output routing |
| Guaranteed 1Ω on-resistance match | Ensures ≤0.1% gain mismatch across channels - critical for multi-channel calibration and differential measurement |
| Low charge injection (3pC) | Minimizes voltage glitch on sampled-hold nodes - improves accuracy in switched-capacitor ADC front-ends |
| High off-isolation (–93dB) and low crosstalk (–96dB) | Prevents signal bleed between active/inactive paths - maintains channel integrity in multi-source A/V matrixes |
| Pin compatibility with 74HC4052/MAX4582 | Enables direct replacement in existing designs without PCB revision - reduces qualification time and NRE cost |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC4052D | Higher on-resistance (120Ω typ at +4.5V), slower switching (tON/tOFF ≈ 75ns), no guaranteed RON match | Suitable for non-critical digital signal routing; not recommended for precision analog or high-speed acquisition | Select MAX4618CUE when ≤10Ω RON, <20ns timing, or sub-1Ω matching is required. |
| MAX4582ESE+ | Identical pinout and function; same BiCMOS process; identical RON, leakage, and isolation specs; rated for –40°C to +85°C | Extended temperature operation; otherwise drop-in compatible in all electrical and layout aspects | Choose MAX4582ESE+ for industrial environments requiring wider temp range; MAX4618CUE preferred for commercial-grade cost-sensitive designs. |
Compared with 74HC4052D, MAX4618CUE delivers 12× lower on-resistance and 5× faster switching for precision analog paths; versus MAX4582ESE+, it trades extended temperature rating for lower unit cost in 0°C to +70°C applications.

FAQ
What is the maximum supply voltage rating for the MAX4618CUE?
The MAX4618CUE has an absolute maximum supply voltage of +6V referenced to GND, but its specified operational range is +2V to +5.5V. Operating above +5.5V risks permanent damage and violates the device's guaranteed specifications. For robust design, maintain VCC within +4.5V to +5.5V when targeting full performance per the datasheet's Electrical Characteristics tables.
Does the MAX4618CUE support bidirectional signal flow?
Yes, the MAX4618CUE supports fully bidirectional analog signal flow. Its CMOS switch architecture makes all analog terminals (X0–X3, X, Y0–Y3, Y) electrically symmetric - either side can serve as input or output without performance degradation. This enables flexible use in transceiver signal paths, feedback networks, and reconfigurable filter topologies where signal direction may vary dynamically.
How does the ENABLE pin function on the MAX4618CUE?
The ENABLE pin (Pin 6) is an active-low control that globally disables both 4:1 multiplexer sections. When pulled high (≥2.4V at +5V supply), all internal switches open regardless of address inputs, presenting high off-isolation (>–93dB). When pulled low (≤0.8V), the device responds to A/B address lines to route selected channels. This allows power-aware systems to gate analog signal paths during idle periods, reducing system-level leakage and noise coupling.
What is the guaranteed on-resistance match between channels for the MAX4618CUE?
The MAX4618CUE guarantees ≤1Ω on-resistance match (ΔRON) between any two channels when operated at +5V supply and +25°C. This specification - defined as RON(max) – RON(min) - ensures consistent gain and minimal channel-to-channel error in applications like multi-sensor calibration, programmable gain stages, and differential signal switching where ratio-matching is critical to system accuracy.
Is the MAX4618CUE pin-compatible with the 74HC4052?
Yes, the MAX4618CUE is pin-compatible with the industry-standard 74HC4052 in the 16-pin TSSOP package. Pin assignments for analog I/O (X0–X3, X, Y0–Y3, Y), address lines (A, B), ENABLE, VCC, and GND align exactly. However, MAX4618CUE offers superior analog performance: 10× lower on-resistance, 5× faster switching, and guaranteed matching - making it a functional upgrade without layout changes.
