Product details
Overview
MAX4618CSE+T 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 routing in battery-powered instrumentation.
For engineers reviewing the MAX4618CSE+T datasheet, MAX4618CSE+T pinout, MAX4618CSE+T application, or MAX4618CSE+T equivalent, this device is selected for low-distortion (<0.017%), low-crosstalk (–96dB), and matched-channel switching in portable data-acquisition and communications signal-path designs.
Technical Context
The MAX4618CSE+T implements two independent 4:1 analog multiplexers with shared digital control (A/B/ENABLE) and separate analog I/O banks (X0–X3/X and Y0–Y3/Y). Each multiplexer uses complementary CMOS switch architecture with internal ESD diodes clamping analog terminals to VCC and GND.
It supports break-before-make switching with <1.5ns tBBM, guarantees 1Ω on-resistance match between channels at +5V, and maintains low off-isolation (–93dB) and charge injection (3pC) - critical for precision sampling and low-noise signal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +5.5V single supply - enables direct integration into 3.3V and 5V systems without level-shifting. |
| tON / tOFF | 15ns / 10ns at +5V - supports >30MHz switching rates in high-speed data acquisition. |
| RON (max) | 10Ω at +5V, 20Ω at +3V - ensures minimal signal attenuation and gain error in sensor front-ends. |
| Off-Leakage | 1nA at +25°C, 10nA at +85°C - preserves accuracy in high-impedance measurement paths. |
| Crosstalk | –96dB at 100kHz - prevents interference between adjacent channels in multi-signal routing. |
| THD | <0.017% at 600Ω load - maintains fidelity in audio and precision analog signal chains. |
| Logic Thresholds | 0.8V to 2.4V at +5V - ensures robust compatibility with TTL and CMOS drivers without external biasing. |
Pinout & Package
MAX4618CSE+T is housed in a 16-pin narrow SO (Small Outline) package with 1.27mm pitch, RoHS-compliant, rated for 0°C to +70°C operation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | X0 | Analog input channel 0 for X-multiplexer - connects to selected output X when address A=0,B=0. |
| 2 | X1 | Analog input channel 1 for X-multiplexer - active when A=1,B=0. |
| 3 | X2 | Analog input channel 2 for X-multiplexer - active when A=0,B=1. |
| 4 | X3 | Analog input channel 3 for X-multiplexer - active when A=1,B=1. |
| 5 | Y0 | Analog input channel 0 for Y-multiplexer - independently selectable via same A/B controls. |
| 6 | Y1 | Analog input channel 1 for Y-multiplexer - enables dual parallel 4:1 routing paths. |
| 7 | Y2 | Analog input channel 2 for Y-multiplexer - isolated electrically from X-bank except by shared control logic. |
| 8 | Y3 | Analog input channel 3 for Y-multiplexer - supports simultaneous or staggered channel selection. |
| 9 | A | LSB address input - determines lower bit of 2-bit channel select for both X and Y banks. |
| 10 | B | MSB address input - determines upper bit of 2-bit channel select; jointly controls X and Y sections. |
| 11 | ENABLE | Active-low global enable - pulls all switches open when high, overriding address inputs. |
| 12 | X | Common output for X-multiplexer - carries selected X0–X3 signal; bidirectional and rail-to-rail capable. |
| 13 | Y | Common output for Y-multiplexer - independent of X path; supports dual-output signal distribution. |
| 14 | N.C. | No internal connection - must be left unconnected; no electrical function or thermal role. |
| 15 | GND | Analog/digital ground reference - serves as return path for all leakage, switching, and logic currents. |
| 16 | VCC | Positive supply - powers internal CMOS switches and logic; sets analog signal range (0V to VCC). |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility | Fully pin-compatible with industry-standard 74HC4052 and MAX4582 - allows drop-in replacement without PCB redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4:1 analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum analog signal voltage range supported by the MAX4618CSE+T?
The MAX4618CSE+T supports rail-to-rail analog signals from 0V to VCC. With a +5.5V supply, this means signals from 0V to +5.5V are fully passed without clipping or distortion. The internal ESD diodes clamp voltages beyond VCC or GND, so exceeding these limits risks damage unless external protection is added.
Does the MAX4618CSE+T support bidirectional signal flow?
Yes, the MAX4618CSE+T supports fully bidirectional analog signal flow - any pin labeled X0–X3, Y0–Y3, X, or Y may serve as input or output. This is explicitly confirmed in the datasheet's "Applications Information" section, which states "Input and output pins are identical and interchangeable."
Can the MAX4618CSE+T operate from a +3.3V supply, and what performance changes occur?
Yes, the MAX4618CSE+T operates from +3.3V (within its +2V to +5.5V range). At +3V supply, RON increases to 20Ω max (vs. 10Ω at +5V), tON/tOFF increase to 20ns/15ns, and logic thresholds adjust to 0.5V/2.0V. All other parameters - including leakage, crosstalk, and THD - remain within guaranteed limits.
Is the MAX4618CSE+T pin-compatible with the 74HC4052, and are there functional differences?
Yes, the MAX4618CSE+T is pin-compatible with the 74HC4052 in 16-pin SO packages and shares identical logic diagrams. However, it offers faster switching (15ns vs. ~70ns), lower on-resistance (10Ω vs. 120Ω), and guaranteed specifications for RON match, THD, and off-isolation - making it a performance upgrade, not just a drop-in replacement.
What is the thermal performance of the MAX4618CSE+T in narrow SO package?
The MAX4618CSE+T in narrow SO package has a thermal derating factor of 8.70mW/°C above +70°C, with a maximum continuous power dissipation of 696mW at TA = +70°C. Its BiCMOS process ensures stable RON and leakage behavior across the full 0°C to +70°C operating range, with no thermal shutdown or latch-up observed under normal conditions.
