Product details
Overview
MAX4618CPE 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 analog signal handling, and TTL/CMOS-compatible logic thresholds - enabling precise signal routing in battery-powered audio/video systems.
For engineers reviewing the MAX4618CPE datasheet, MAX4618CPE pinout, MAX4618CPE application, or MAX4618CPE equivalent, this device serves as a pin-compatible upgrade to industry-standard 74HC4052 with guaranteed on-resistance matching (≤1Ω), low crosstalk (−96dB), and validated performance across 0°C to +70°C industrial temperature range.
Technical Context
The MAX4618CPE implements two independent 4:1 analog multiplexers sharing common address lines (A, B) and enable control, supporting simultaneous or selective channel selection. Its BiCMOS process ensures fast switching with sub-20ns propagation delays and minimal charge injection (3pC) for low distortion in precision signal paths.
All analog terminals tolerate rail-to-rail signals up to VCC + 0.3V and down to −0.3V, with internal ESD diodes clamping overvoltage transients. Digital inputs maintain 0.8V–2.4V logic thresholds at +5V supply, scaling proportionally with VCC to retain compatibility across +2.5V to +5.5V operation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-channel analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC4052N | Higher on-resistance (120Ω typ at +4.5V), slower switching (≈100ns), no guaranteed RON match | Suitable for non-critical digital control signals but not precision analog routing | Choose MAX4618CPE where low distortion, tight RON matching, or <20ns timing is required |
| MAX4582CPE+ | Same pinout and function; 25Ω max RON at +5V, 25ns tON, higher off-leakage (5nA) | Acceptable for general-purpose routing but less suitable for high-accuracy sensor front-ends | Prefer MAX4618CPE for lower on-resistance, faster switching, and tighter leakage specs |

FAQ
What is the maximum analog signal voltage range supported by the MAX4618CPE?
The MAX4618CPE supports rail-to-rail analog signals from GND to VCC. With absolute maximum ratings allowing −0.3V to (VCC + 0.3V), it safely handles signals extending slightly beyond supply rails - critical for AC-coupled audio or transient-tolerant sensor interfaces. At +5V supply, this yields a usable range of 0V to +5V with margin for overshoot.
Does the MAX4618CPE require separate analog and digital ground connections?
No, the MAX4618CPE uses a single ground pin (Pin 8) for both analog and digital functions. Its BiCMOS design integrates noise isolation internally, eliminating the need for split grounds. Layout best practice remains star grounding at Pin 8 and short, low-inductance traces to minimize coupling between digital switching and analog paths.
Can the MAX4618CPE operate reliably at 2.5V supply voltage?
Yes, the MAX4618CPE is fully specified down to +2.5V supply. At this voltage, on-resistance increases to 30Ω (typ), switching times extend to ~12ns, and logic thresholds scale to 2.0V (high) and 0.5V (low). Performance remains robust for low-power portable designs, though RON match degrades slightly versus +5V operation.
How does the ENABLE pin function in the MAX4618CPE?
The ENABLE pin (Pin 6) is active-low: pulling it high opens all switches (high-impedance state), while driving it low enables normal address-controlled multiplexing. It operates independently of address inputs, providing hardware-level channel disable capability - useful for power gating, fault isolation, or system-level sleep mode control in the MAX4618CPE.
Is the MAX4618CPE pin-compatible with the MAX4582 series?
Yes, the MAX4618CPE is pin-compatible with the MAX4582CPE+ and shares identical pinout, truth table, and functional behavior. However, the MAX4618CPE offers improved specifications: 10Ω vs. 25Ω max on-resistance at +5V, 15ns vs. 25ns tON, and 1nA vs. 5nA off-leakage - making it a performance-enhanced drop-in alternative for the MAX4582CPE+.
