Product details
Overview
The MAX4618CEE+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 rail-to-rail signal handling, 15ns turn-on time, 10ns turn-off time, and guaranteed 10Ω max on-resistance at +5V - enabling precise signal routing in battery-powered audio/video systems and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4618CEE+T datasheet, MAX4618CEE+T pinout, MAX4618CEE+T application, or MAX4618CEE+T equivalent, this device is selected for designs requiring fast, low-leakage, TTL/CMOS-compatible switching with minimal channel-to-channel crosstalk (-96dB) and high off-isolation (-93dB) in space-constrained TSSOP-16 layouts.
Technical Context
The MAX4618CEE+T integrates two independent 4-channel analog multiplexers sharing common address (A, B) and enable inputs. Each multiplexer routes one of four analog inputs (X0–X3 or Y0–Y3) to its respective output (X or Y) under digital control, with break-before-make switching and guaranteed monotonic on-resistance across temperature.
Its BiCMOS process delivers low charge injection (3pC), low on-resistance match (≤1Ω at +5V), and stable performance over ±2.5V to ±5.5V analog signal ranges. Input logic thresholds scale with VCC (2.4V min at +5V; 2.0V min at +3V), ensuring compatibility across mixed-supply systems without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | +2V to +5.5V single supply - supports direct integration into 3.3V and 5V systems without regulators. |
| On-Resistance (max) | 10Ω at +5V - ensures minimal signal attenuation and gain error in precision sensor or audio paths. |
| tON/tOFF | 15ns / 10ns - enables high-speed multiplexing in sampling systems up to ~30MHz effective rate. |
| Off-Leakage Current | 1nA at +25°C - preserves accuracy in high-impedance measurement nodes (e.g., pH sensors, photodiode amps). |
| Crosstalk / Off-Isolation | -96dB / -93dB at 100kHz - prevents interference between active and inactive channels in multi-signal routing. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V–2.4V at +5V) - interfaces directly with microcontrollers and FPGAs without glue logic. |
| Package | 16-pin TSSOP (EE) - 5mm × 4.4mm footprint suitable for compact portable and industrial PCBs. |
Pinout & Package
MAX4618CEE+T is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package) with exposed pad, JEDEC MO-153 compliant, 0.65mm pitch, and RoHS-compliant lead-free finish.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | X0 | Analog input channel 0 for first multiplexer - bidirectional, rail-to-rail capable. |
| 2 | X1 | Analog input channel 1 for first multiplexer - electrically identical to X0, matched RON. |
| 3 | X2 | Analog input channel 2 for first multiplexer - shares same on-resistance flatness spec (≤1Ω). |
| 4 | X3 | Analog input channel 3 for first multiplexer - used with A/B address lines to select active path. |
| 5 | Y0 | Analog input channel 0 for second multiplexer - independent of X-side, enables dual-path routing. |
| 6 | Y1 | Analog input channel 1 for second multiplexer - supports simultaneous but separate signal selection. |
| 7 | Y2 | Analog input channel 2 for second multiplexer - no internal coupling to X-side channels. |
| 8 | Y3 | Analog input channel 3 for second multiplexer - full 4:1 routing capability per section. |
| 9 | A | LSB address input - controls bit 0 of channel selection (0 = X0/Y0, 1 = X1/Y1, etc.). |
| 10 | B | MSB address input - controls bit 1 of channel selection (00 = X0/Y0, 01 = X1/Y1, 10 = X2/Y2, 11 = X3/Y3). |
| 11 | ENABLE | Digital enable input - logic high disables both multiplexers; tied low for always-on operation. |
| 12 | X | Common output for first multiplexer - connects to selected X0–X3 channel when ENABLE = low. |
| 13 | Y | Common output for second multiplexer - connects to selected Y0–Y3 channel when ENABLE = low. |
| 14 | N.C. | No internal connection - must be left floating or grounded; no electrical function. |
| 15 | GND | Analog/digital ground reference - shared return for all signals and supplies; critical for leakage control. |
| 16 | VCC | Positive supply input - 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 - enables drop-in replacement without layout change. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4582ESE+ | Same pinout, identical truth table, but higher on-resistance (15Ω max at +5V) and slower tON (25ns). | Suitable for cost-sensitive, non-high-speed applications where 10Ω RON is not required. | Select MAX4582ESE+ only if design tolerates +5Ω RON and 10ns slower switching. |
| 74HC4052PW,118 | Pin-compatible, but wider on-resistance variation (120Ω typ at +4.5V), no guaranteed RON match, and no 1nA leakage spec. | Appropriate for general-purpose digital-control analog routing where precision leakage and matching are non-critical. | Choose 74HC4052PW,118 only for non-precision, low-cost consumer applications with relaxed specs. |
Compared with MAX4582ESE+ and 74HC4052PW,118, the MAX4618CEE+T delivers superior on-resistance consistency, lower leakage, and faster switching - making it the preferred choice for battery-powered test equipment and high-fidelity audio routing where signal integrity is paramount.

FAQ
What is the maximum analog signal voltage range supported by the MAX4618CEE+T?
The MAX4618CEE+T supports rail-to-rail analog signals from 0V to VCC. When operated at +5V supply, the analog input/output range is 0V to +5V; at +3.3V supply, it is 0V to +3.3V. Exceeding VCC or going below GND risks forward-biasing internal ESD diodes, so signals must remain within these bounds for reliable operation. The MAX4618CEE+T does not support dual-supply or negative-voltage operation.
Does the MAX4618CEE+T require external pull-up or pull-down resistors on its address or enable pins?
No, the MAX4618CEE+T does not require external pull-up or pull-down resistors on A, B, or ENABLE pins. Its digital inputs have guaranteed TTL/CMOS-compatible thresholds (0.8V low, 2.4V high at +5V) and draw less than 1µA input current. However, ENABLE should be actively driven - tying it permanently low enables both multiplexers, while driving it high disables all channels. Floating ENABLE is not recommended due to potential noise-induced switching.
Can the MAX4618CEE+T be used in bidirectional signal paths?
Yes, the MAX4618CEE+T supports fully bidirectional analog signal flow. Its CMOS switch architecture makes input and output pins functionally identical - X0–X3 and Y0–Y3 can serve as either sources or sinks, and X/Y outputs can accept signals from external sources. This enables flexible use in analog crosspoint matrices, feedback path switching, and I/O multiplexing without directional constraints. The MAX4618CEE+T datasheet explicitly confirms interchangeability of all analog terminals.
What is the thermal performance of the MAX4618CEE+T in TSSOP package at full load?
In its 16-pin TSSOP package, the MAX4618CEE+T has a thermal resistance θJA of 9.4mW/°C above +70°C, with a maximum continuous power dissipation of 755mW at TA = +70°C. Under typical operation (VCC = +5V, 10mA per channel), power dissipation remains well below this limit - less than 1mW - ensuring stable operation without heatsinking. The MAX4618CEE+T operates reliably from -40°C to +85°C ambient, with leakage and RON fully characterized across this range.
How does the MAX4618CEE+T compare to the MAX4052 in terms of on-resistance and speed?
The MAX4618CEE+T offers significantly lower on-resistance (10Ω max at +5V vs. 120Ω max for MAX4052) and faster switching (15ns tON vs. 150ns for MAX4052). It also guarantees ≤1Ω on-resistance matching between channels - a spec not provided for MAX4052. These differences make the MAX4618CEE+T suitable for precision, high-speed applications like portable instrumentation and professional audio, whereas MAX4052 targets general-purpose, low-frequency routing. Both share the same pinout and logic interface.
