Product details
Overview
MAX4618EPE from Analog Devices is a high-speed, low-voltage CMOS dual 4-channel analog multiplexer configured for bidirectional signal routing in single-supply systems. It supports rail-to-rail analog signals from +2V to +5.5V, delivers 15ns turn-on time, 10ns turn-off time, and guarantees ≤10Ω on-resistance at +5V - enabling precision audio/video switching and low-voltage data acquisition.
For engineers reviewing the MAX4618EPE datasheet, MAX4618EPE pinout, MAX4618EPE application, or MAX4618EPE equivalent, this device is selected for its TTL/CMOS-compatible logic thresholds, <−96dB crosstalk, 1Ω on-resistance match between channels, and pin compatibility with 74HC4052 and MAX4582 in 16-pin PDIP packaging.
Technical Context
The MAX4618EPE integrates two independent 4:1 analog multiplexers sharing common address (A, B) and enable inputs, with separate X and Y output buses. Each channel uses matched CMOS transmission gates driven by decoded logic to ensure monotonic on-resistance and minimal charge injection (3pC).
Its architecture supports break-before-make switching (≤1.5ns), operates without external biasing, and maintains signal integrity via low off-capacitance (15pF) and high off-isolation (−93dB at 100kHz), making it suitable for high-fidelity analog path selection in mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +5.5V single supply - enables direct interface with 3.3V and 5V logic without level shifters |
| On-Resistance (max) | 10Ω at +5V - ensures minimal voltage drop and gain error in sensor/ADC front-ends |
| On-Resistance Match | 1Ω max between channels at +5V - critical for multi-channel instrumentation requiring matched gain paths |
| Switching Time (tON/tOFF) | 15ns / 10ns - supports >20MHz analog signal routing with low timing skew |
| Off-Leakage Current | 1nA at +25°C - preserves accuracy in high-impedance circuits (e.g., pH sensors, photodiode amps) |
| Crosstalk | <−96dB at 100kHz - prevents interference between active and inactive channels in A/V routing |
| Off-Isolation | <−93dB at 100kHz - blocks signal coupling from disabled channels into sensitive receive paths |
Pinout & Package
MAX4618EPE is housed in a 16-pin plastic DIP (PDIP) package with 0.3-inch body width, through-hole mounting, and RoHS-compliant lead finish. Pin spacing is 0.1 inch, compatible with standard IC sockets and prototyping boards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | X1 | Analog input channel 1 for X-side multiplexer - selected when A=1, B=0 |
| 3 | X2 | Analog input channel 2 for X-side multiplexer - selected when A=0, B=1 |
| 4 | X3 | Analog input channel 3 for X-side multiplexer - selected when A=1, B=1 |

| 7 | Y2 | Analog input channel 2 for Y-side multiplexer - supports parallel signal conditioning architectures |
| 8 | Y3 | Analog input channel 3 for Y-side multiplexer - allows independent routing of two 4:1 streams |
| 9 | A | LSB address input - controls channel selection bit for both X and Y muxes |
| 10 | B | MSB address input - completes 2-bit decode for 4-channel selection per bus |
| 11 | ENABLE | Digital enable input - logic high disables all switches; tied to GND for always-on operation |
| 12 | N.C. | No internal connection - must remain unconnected; no pull-up/down required |
| 13 | GND | Analog/digital ground reference - shared return for supply and signal paths |
| 14 | X | Common output for X-side multiplexer - carries selected X0–X3 signal to downstream circuitry |
| 15 | Y | Common output for Y-side multiplexer - carries selected Y0–Y3 signal independently of X bus |
| 16 | VCC | Positive supply input - powers internal logic and switch transistors; range +2V to +5.5V |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4052/MAX4582 | Direct replacement in existing 16-pin PDIP layouts - eliminates PCB redesign for upgrade paths |

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 |
|---|---|---|---|
| MAX4582EPE+ | Same pinout, identical function, but rated only for 0°C to +70°C industrial range (vs. −40°C to +85°C for MAX4618EPE) | Suitable for commercial-grade equipment; not qualified for extended temperature environments | Select MAX4582EPE+ only if ambient operating temperature remains within 0°C–70°C and long-term reliability at extremes is not required. |
| 74HC4052N | Higher on-resistance (120Ω typical at +4.5V), slower switching (tON ≈ 60ns), no guaranteed RON match or leakage specs | Acceptable for non-critical digital control or low-frequency analog paths where precision is secondary | Choose 74HC4052N only for cost-sensitive, non-precision applications where 10Ω RON and 15ns speed are unnecessary. |
Compared with MAX4582EPE+ and 74HC4052N, the MAX4618EPE provides superior thermal robustness, tighter parametric guarantees, and lower distortion - making it the preferred choice for industrial, medical, and portable test equipment demanding repeatable analog performance across temperature.

FAQ
What is the operating temperature range of the MAX4618EPE?
The MAX4618EPE is specified for operation from −40°C to +85°C, as indicated by the "E" grade suffix in its part number. This extended industrial temperature range ensures reliable performance in harsh environments such as outdoor instrumentation, automotive cabin electronics, and industrial control panels where thermal cycling occurs.
Can the MAX4618EPE operate from a +3.3V supply?
Yes, the MAX4618EPE operates fully from a +3.3V supply. At +3V, it guarantees ≤20Ω on-resistance and maintains 1nA leakage performance. Logic thresholds scale accordingly (2.0V high, 0.5V low), ensuring compatibility with 3.3V microcontrollers and FPGAs without level translation.
Is the MAX4618EPE pin-compatible with the 74HC4052?
Yes, the MAX4618EPE is pin-compatible with the 74HC4052 in the 16-pin PDIP package. Both share identical pin assignments for X0–X3, Y0–Y3, X, Y, A, B, ENABLE, VCC, GND, and N.C. However, the MAX4618EPE offers significantly lower on-resistance, faster switching, and guaranteed matching not found in the HC-series device.
Does the MAX4618EPE support bidirectional analog signal flow?
Yes, the MAX4618EPE supports fully bidirectional analog signal routing. Its CMOS transmission-gate architecture imposes no directionality - signals pass equally well from X0–X3 to X or from X to X0–X3, and similarly for the Y-side. This enables flexible use in both input multiplexing and output demultiplexing configurations.
What is the maximum analog signal voltage the MAX4618EPE can handle?
The MAX4618EPE supports rail-to-rail analog signals from GND to VCC. With a +5.5V supply, it handles up to +5.5V; with a +2.5V supply, it handles 0V to +2.5V. Absolute maximum analog voltage is limited to VCC + 0.3V or −0.3V relative to GND - exceeding this risks ESD diode conduction and potential damage.
