Product details
Overview
MAX4618EUE from Analog Devices is a high-speed, low-voltage CMOS dual 4-channel analog multiplexer operating from a single +2V to +5.5V supply, featuring 15ns turn-on time, 10ns turn-off time, 10Ω max on-resistance at +5V, rail-to-rail signal handling, and TTL/CMOS logic compatibility - used for precision audio/video routing and low-voltage data-acquisition channel selection.
For engineers reviewing the MAX4618EUE datasheet, MAX4618EUE pinout, MAX4618EUE application, or MAX4618EUE equivalent, this page delivers verified electrical specs, package mapping, functional truth table alignment, and real-world switching performance data critical for battery-powered instrumentation and signal-path integrity validation.
Technical Context
The MAX4618EUE implements two independent 4:1 analog multiplexers sharing common address lines (A, B) and a global ENABLE input, with each section selecting one of four bidirectional analog inputs (X0–X3 or Y0–Y3) to its respective output (X or Y). Its BiCMOS process enables fast switching while maintaining low leakage and matched on-resistance across channels.
All digital inputs accept 0.8V to 2.4V thresholds under +5V supply, ensuring robust interface with microcontrollers and FPGAs; analog terminals support rail-to-rail signals up to VCC, with off-isolation of –93dB and crosstalk below –96dB at 100kHz - confirming suitability for high-fidelity, multi-channel signal routing where channel separation is critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4582ESE+ | Same pinout, 12ns tON, 25Ω RON at +3.3V - higher on-resistance, lower speed at low voltage. | Optimized for +3.3V systems with relaxed RON tolerance; less suitable for precision <10Ω paths. | Select MAX4582ESE+ only when prioritizing cost over on-resistance spec in 3.3V-only designs. |
| 74HC4052D,653 | Industry-standard SO16, 80Ω RON at +4.5V, 120ns switching - significantly slower and higher resistance. | General-purpose routing where speed and precision are non-critical; not suitable for audio or data acquisition. | Choose 74HC4052D,653 only for cost-sensitive, low-performance applications with ample timing margin. |
Compared with MAX4618EUE, MAX4582ESE+ trades 10Ω on-resistance and 15ns speed for broader 3.3V optimization, while 74HC4052D,653 sacrifices >8× switching speed and >8× on-resistance for commodity availability - making MAX4618EUE the only choice for high-fidelity, low-latency dual-channel routing.

FAQ
What is the maximum operating temperature range for the MAX4618EUE?
The MAX4618EUE is specified for operation from –40°C to +85°C, as indicated by the "E" grade suffix in its part number. This extended temperature range makes it suitable for industrial and automotive-adjacent applications where ambient conditions exceed commercial-grade limits. Electrical characteristics including on-resistance, leakage, and switching times are guaranteed across this full range per the datasheet's "Electrical Characteristics-Single +5V Supply" tables.
Does the MAX4618EUE support rail-to-rail analog signal operation?
Yes, the MAX4618EUE supports rail-to-rail analog signal operation - meaning it can pass signals from GND to VCC without clipping or distortion. This capability is explicitly confirmed in the "Analog-Signal Range" parameter (VX, VY = 0 to VCC) and is enabled by its BiCMOS architecture and internal level-shifting circuitry. It is essential for preserving full dynamic range in single-supply sensor interfaces and audio circuits.
Is the MAX4618EUE pin-compatible with the 74HC4052?
Yes, the MAX4618EUE is pin-compatible with the industry-standard 74HC4052, as stated in the "Features" section and "Pin Nomenclature" subsection of the datasheet. Both devices use identical 16-pin TSSOP/SO/DIP footprints and share the same pin assignments for X0–X3, Y0–Y3, X, Y, A, B, ENABLE, GND, VCC, and N.C. This allows direct replacement without PCB modification.
What is the typical on-resistance of the MAX4618EUE at +3.3V supply?
At +3.3V supply, the MAX4618EUE has a guaranteed maximum on-resistance of 20Ω (typical 13Ω), measured at 10mA load and 1.5V analog signal level. This value is documented in the "Electrical Characteristics-Single +3V to +3.6V Supply" table. The on-resistance increases as supply voltage decreases, reaching ~60Ω at +2.5V - a key consideration for low-voltage precision applications.
How does the ENABLE pin function on the MAX4618EUE?
The ENABLE pin on the MAX4618EUE is an active-low control that globally disables both multiplexer sections. When ENABLE is logic high, all analog switches open regardless of address inputs A and B - effectively isolating all inputs from outputs. When ENABLE is logic low, channel selection proceeds normally via A/B inputs. This feature enables system-level power gating and fault-safe signal isolation in safety-critical designs.
