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 signal handling, and TTL/CMOS-compatible logic thresholds - enabling precise audio/video routing in battery-powered instrumentation.
For engineers reviewing the MAX4618CSE datasheet, MAX4618CSE pinout, MAX4618CSE application, or MAX4618CSE equivalent, this device serves as a pin-compatible upgrade to 74HC4052 with guaranteed low crosstalk (–96dB), high off-isolation (–93dB), and matched on-resistance (≤1Ω) for precision signal path selection in mixed-signal systems.
Technical Context
The MAX4618CSE integrates two independent 4-channel analog multiplexers sharing common address lines (A, B) and enable control. Each multiplexer routes one of four bidirectional analog inputs (X0–X3 or Y0–Y3) to its respective output (X or Y) under digital control, supporting simultaneous or staggered channel selection.
Its BiCMOS process ensures fast switching with minimal charge injection (3pC) and low distortion (<0.017% at 600Ω), while internal ESD diodes clamp analog signals to VCC/GND - requiring proper power sequencing but enabling robust operation in noisy environments without external protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V single supply - supports direct interface with Li-ion battery (3.0–3.7V) and 3.3V/5V logic domains without level shifting. |
| On-Resistance (max) | 10Ω at +5V, 20Ω at +3V - ensures minimal voltage drop and gain error in sensor front-ends and DAC output routing. |
| Switching Speed | tON = 15ns, tOFF = 10ns (VCC = +5V) - enables sampling of signals up to ~35MHz without timing skew between channels. |
| Off-Leakage Current | 1nA at +25°C, 10nA at +85°C - preserves accuracy in high-impedance pH sensors or piezoelectric transducer interfaces. |
| Crosstalk / Off-Isolation | –96dB crosstalk, –93dB off-isolation at 100kHz - prevents interference between adjacent video channels or multi-sensor data acquisition paths. |
| Logic Compatibility | 0.8V to 2.4V input thresholds at +5V - guarantees reliable switching with standard TTL and CMOS outputs without pull-ups or buffers. |
Pinout & Package
MAX4618CSE 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/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | X0 | Analog input channel 0 for X-side multiplexer - connects to source signal when A=0, B=0, ENABLE=L. |
| 2 | X1 | Analog input channel 1 for X-side multiplexer - selected with A=1, B=0, ENABLE=L. |
| 3 | X2 | Analog input channel 2 for X-side multiplexer - selected with A=0, B=1, ENABLE=L. |
| 4 | X3 | Analog input channel 3 for X-side multiplexer - selected with A=1, B=1, ENABLE=L. |
| 5 | Y0 | Analog input channel 0 for Y-side multiplexer - shares same address decoding as X-side. |
| 6 | Y1 | Analog input channel 1 for Y-side multiplexer - enables parallel dual-path routing (e.g., stereo left/right). |
| 7 | Y2 | Analog input channel 2 for Y-side multiplexer - isolated from X-side except via shared address/control lines. |
| 8 | Y3 | Analog input channel 3 for Y-side multiplexer - supports independent selection timing from X-side channels. |
| 9 | A | LSB address input - controls bit 0 of 2-bit channel select for both X and Y multiplexers. |
| 10 | B | MSB address input - controls bit 1 of 2-bit channel select; together with A, selects one of four inputs per side. |
| 11 | ENABLE | Active-low global enable - drives all switches open (high-Z) when logic high; required for power-down or fault isolation. |
| 12 | X | Common output for X-side multiplexer - carries selected X0–X3 signal bidirectionally. |
| 13 | Y | Common output for Y-side multiplexer - carries selected Y0–Y3 signal bidirectionally; electrically isolated from X node. |
| 14 | N.C. | No internal connection - must be left unconnected; not usable as spare I/O or thermal pad. |
| 15 | GND | Analog/digital ground reference - requires low-impedance star connection to minimize switching noise coupling into analog paths. |
| 16 | VCC | Positive supply for analog switch core and logic - must be decoupled with ≥100nF ceramic capacitor near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility | Fully pin-compatible with industry-standard 74HC4052 and MAX4582 - allows drop-in replacement without PCB revision. |
| Rail-to-rail analog range | Supports signals from GND to VCC - eliminates clipping in single-supply op-amp circuits and ADC driver stages. |
| On-resistance matching | ≤1Ω max difference between any two channels at +5V - critical for gain-matched multi-channel instrumentation amplifiers. |
| Low charge injection | 3pC typical - minimizes voltage glitch on high-impedance nodes (e.g., sample-and-hold capacitors) during switching. |
| High-frequency isolation | –93dB off-isolation at 100kHz - maintains signal integrity in RF-adjacent analog subsystems and communication receivers. |

FAQ
What is the maximum analog signal voltage range supported by the MAX4618CSE?
The MAX4618CSE supports rail-to-rail analog signals from GND to VCC. When operated at +5V supply, this means signals from 0V to +5V are fully passed without clipping. The device's internal ESD diodes clamp voltages beyond these limits, so exceeding VCC or going below GND risks forward conduction and potential damage unless external protection is added.
Does the MAX4618CSE require separate analog and digital supplies?
No, the MAX4618CSE uses a single supply (VCC) for both analog switching and digital control logic. VCC powers the internal CMOS transmission gates and sets the logic threshold levels - which scale with supply voltage (e.g., 2.0V min high-level at +3V VCC). No AVCC/DVCC separation or isolation is needed.
Can the MAX4618CSE be used in bidirectional signal paths?
Yes, the MAX4618CSE is fully bidirectional: any analog pin (X0–X3, Y0–Y3, X, Y) can serve as input or output. Signal direction is determined by external circuitry, not internal architecture. This enables flexible use in T/R switching, loopback testing, or shared-bus configurations without polarity constraints.
What is the guaranteed on-resistance match between channels of the MAX4618CSE?
The MAX4618CSE guarantees ≤1Ω on-resistance match (ΔRON) between any two channels when operated at +5V supply and TA = +25°C. This specification ensures consistent gain and minimal channel-to-channel error in applications like programmable-gain amplifiers or multi-channel calibration systems.
Is the MAX4618CSE pin-compatible with the 74HC4052?
Yes, the MAX4618CSE is explicitly designed to be pin-compatible with the 74HC4052 and MAX4582. Pin assignments for X0–X3, Y0–Y3, X, Y, A, B, ENABLE, GND, and VCC align exactly - enabling direct substitution without layout changes, provided the system operates within the MAX4618CSE's voltage and temperature specifications.
