Product details
Overview
MAX4618CSE+ 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 and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4618CSE+ datasheet, MAX4618CSE+ pinout, MAX4618CSE+ application, or MAX4618CSE+ equivalent, this page delivers verified electrical parameters, functional pin mapping, real-world use cases, and validated alternative parts for design-in and sourcing decisions.
Technical Context
The MAX4618CSE+ implements two independent 4:1 analog multiplexers sharing common address (A, B) and enable inputs, with separate X and Y analog buses. Each channel supports bidirectional signal flow and guarantees ≤1Ω on-resistance matching between channels under +5V supply - critical for precision gain-switching and sensor multiplexing where channel-to-channel consistency matters.
Its BiCMOS process enables fast switching (tON/tOFF < 20ns), ultra-low leakage (1nA off-leakage at +25°C), and high off-isolation (–93dB) and crosstalk rejection (–96dB) at 100kHz - making it suitable for high-fidelity audio routing and sensitive instrumentation where signal integrity and channel independence are essential.
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 level-shifting. |
| On-Resistance (RON) | 10Ω max at +5V - ensures minimal insertion loss and voltage drop in precision analog paths. |
| On-Resistance Match | ≤1Ω between channels at +5V - enables accurate ratiometric measurements and matched gain stages. |
| Switching Speed | tON = 15ns, tOFF = 10ns - supports high-throughput data acquisition and fast signal reconfiguration. |
| Off-Leakage Current | 1nA at +25°C - preserves accuracy in high-impedance sensor interfaces and battery-critical standby modes. |
| Off-Isolation / Crosstalk | –93dB off-isolation, –96dB crosstalk at 100kHz - maintains channel separation in multi-signal audio and comms routing. |
| Analog Signal Range | Rail-to-rail (0V to VCC) - accommodates full-scale signals without clipping in unipolar systems. |
Pinout & Package
MAX4618CSE+ is housed in a 16-pin narrow SO (Small Outline) package, RoHS-compliant and lead(Pb)-free. Pin spacing is 0.050", body width 0.150", and total length 0.385". This JEDEC-standard SOIC-N package supports automated assembly and offers thermal performance suitable for industrial ambient conditions (0°C to +70°C).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | X0 | Analog input for first 4:1 mux (X-bus channel 0); bidirectional, rail-to-rail compatible. |
| 2 | X1 | Analog input for first 4:1 mux (X-bus channel 1); identical electrical behavior to X0. |
| 3 | X2 | Analog input for first 4:1 mux (X-bus channel 2); shares same RON and leakage specs as X0–X3. |
| 4 | X3 | Analog input for first 4:1 mux (X-bus channel 3); fully interchangeable with other X inputs. |
| 5 | A | LSB address input for both X and Y muxes; TTL/CMOS-compatible threshold (0.8V/2.4V @ +5V). |
| 6 | B | MSB address input for both X and Y muxes; controls channel selection alongside A. |
| 7 | ENABLE | Active-high digital control; drives all switches open when high - enables global signal gating. |
| 8 | GND | Analog/digital ground reference; must be low-impedance for leakage and distortion performance. |
| 9 | Y0 | Analog input for second 4:1 mux (Y-bus channel 0); electrically isolated from X-bus but share address logic. |
| 10 | Y1 | Analog input for second 4:1 mux (Y-bus channel 1); independent signal path with matched RON. |
| 11 | Y2 | Analog input for second 4:1 mux (Y-bus channel 2); supports simultaneous dual-bus operation. |
| 12 | Y3 | Analog input for second 4:1 mux (Y-bus channel 3); no internal coupling to X-bus channels. |
| 13 | X | Common output for X-bus 4:1 mux; connects selected Xn to this terminal when ENABLE = low. |
| 14 | Y | Common output for Y-bus 4:1 mux; independent of X output - enables parallel dual-channel routing. |
| 15 | N.C. | No internal connection - must remain unconnected per datasheet; not usable as spare pin. |
| 16 | VCC | Positive supply for analog and digital circuitry; powers ESD diodes and defines analog signal range. |
Key Features

| Low charge injection (3pC) | Minimizes voltage glitch on sampled nodes - improves accuracy in sample-and-hold and switched-capacitor circuits. |
| High off-isolation (–93dB) | Prevents signal bleed between inactive channels - essential for clean audio mixing and RF test signal routing. |
| TTL/CMOS logic thresholds | Eliminates need for external level shifters when interfacing with microcontrollers or FPGAs operating at +5V. |
Applications
| Audio Signal Routing | Portable Data Acquisition |
|---|---|

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 |
|---|---|---|---|
| MAX4582CSE+ | Same pinout and logic; higher RON (20Ω max @ +5V), slower switching (tON = 25ns), lower off-isolation (–80dB). | Less suitable for precision audio or high-speed DAQ; acceptable for general-purpose signal routing where speed/accuracy margins are relaxed. | Select MAX4582CSE+ only if cost sensitivity outweighs performance requirements - not recommended for new designs targeting <0.02% THD or >100kSPS. |
| ADG708BRUZ | 8-channel single mux (not dual 4:1); 4Ω RON @ +5V, 10ns tON, but lacks shared address architecture - requires separate control lines per channel. | Requires additional GPIO or decoder logic; better for sequential 8:1 selection than parallel X/Y bus routing. | Choose ADG708BRUZ when needing eight independent channels with lowest possible RON, not dual-bus synchronization. |
Compared with MAX4582CSE+, MAX4618CSE+ delivers 2× faster switching and 13dB better off-isolation - critical for high-fidelity audio routing; versus ADG708BRUZ, it provides native dual-bus addressing with zero additional logic, simplifying PCB layout and firmware for stereo or differential signal paths.

FAQ
What is the maximum analog signal voltage supported by MAX4618CSE+?
MAX4618CSE+ supports rail-to-rail analog signals from 0V to VCC. With a +5.5V supply, the absolute maximum analog input is +5.5V; with a +3.3V supply, it is +3.3V. Exceeding VCC or going below GND risks forward-biasing internal ESD diodes - the device is not rated for overvoltage operation beyond its supply rails.
Does MAX4618CSE+ support bidirectional signal flow?
Yes, MAX4618CSE+ supports fully bidirectional analog signal flow. The X and Y buses are symmetrical - any pin (X0–X3, Y0–Y3, X, Y) can serve as input or output depending on signal direction and ENABLE state. This is explicitly confirmed in the datasheet's "Applications Information" section and enables flexible routing in both source-driven and load-driven configurations.
What is the guaranteed on-resistance matching specification for MAX4618CSE+?
MAX4618CSE+ guarantees ≤1Ω on-resistance match (ΔRON) between any two channels when operated at +5V supply and +25°C. This is measured as RON(max) – RON(min) across all eight channels and is tested and specified in the Electrical Characteristics table - critical for ratiometric measurements and matched filter banks.
Can MAX4618CSE+ operate from a +2.5V supply?
Yes, MAX4618CSE+ operates from +2.5V, though with trade-offs: RON increases to 30–60Ω (typical), switching times slow to ~12ns, and logic thresholds scale downward (VIL = 0.5V, VIH = 2.0V). The device remains fully functional and rail-to-rail, but designers must verify timing and impedance budgets meet system requirements at this voltage.
Is MAX4618CSE+ pin-compatible with the 74HC4052?
Yes, MAX4618CSE+ is explicitly pin-compatible and functionally equivalent to the 74HC4052 in single-supply operation. The datasheet confirms identical pinout, logic diagram, and truth table - allowing drop-in replacement without PCB changes, provided the higher performance (lower RON, faster switching, better isolation) of MAX4618CSE+ is leveraged in the design.
