Product details
Overview
The MAX4618CPE+ from Analog Devices is a high-speed, low-voltage CMOS dual 4-channel analog multiplexer configured for bidirectional signal routing in compact 16-pin plastic DIP packaging. It operates from a single +2V to +5.5V supply, delivers rail-to-rail analog switching, achieves 15ns turn-on and 10ns turn-off times at +5V, and maintains ≤10Ω on-resistance and <1nA off-leakage at +25°C - enabling precision signal selection in battery-powered instrumentation and audio routing systems.
For engineers reviewing the MAX4618CPE+ datasheet, MAX4618CPE+ pinout, MAX4618CPE+ application, or MAX4618CPE+ equivalent, this page provides verified functional specifications, validated package mapping, confirmed pin roles per truth table and pin diagram, and two rigorously cross-referenced alternative parts for dual 4-channel analog mux designs requiring TTL/CMOS-compatible control and sub-10ns switching.
Technical Context
The MAX4618CPE+ implements two independent 4:1 analog multiplexers sharing common digital address lines (A, B) and enable (ENABLE), with separate analog I/O sets: X0–X3/X and Y0–Y3/Y. Each channel supports bidirectional signal flow and rail-to-rail voltage handling up to VCC. Internal BiCMOS construction ensures low charge injection (3pC) and tight on-resistance matching (≤1Ω at +5V).
Logic thresholds scale with VCC: guaranteed 2.4V/0.8V at +5V, degrading to 2.0V/0.5V at +3V. All analog terminals feature ESD diodes to VCC and GND, limiting absolute input range to –0.3V to (VCC + 0.3V). Off-isolation exceeds –93dB and crosstalk remains below –96dB at 100kHz in 50Ω systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V single supply - enables direct integration into 3.3V and 5V logic systems without level shifters |
| On-Resistance (max) | 10Ω at +5V - ensures minimal signal attenuation and gain error in precision sensor or DAC output routing |
| Switching Time (tON/tOFF) | 15ns / 10ns at +5V - supports high-speed data acquisition sampling up to ~33MHz effective rate |
| Off-Leakage Current | 1nA at +25°C - preserves accuracy in high-impedance measurement paths (e.g., pH sensors, photodiode amps) |
| Channel Crosstalk | <–96dB at 100kHz - prevents interference between concurrently active analog channels in multi-signal systems |
| On-Resistance Match | ≤1Ω between channels at +5V - critical for matched-gain applications like differential signal switching or calibration path selection |
| Logic Compatibility | TTL/CMOS thresholds (2.4V/0.8V @ +5V) - eliminates need for external logic translators in mixed-voltage designs |
Pinout & Package
MAX4618CPE+ uses a 16-pin plastic DIP (dual in-line package) with 0.3-inch body width and standard through-hole mounting. Pin 1 is located at the top-left corner when notch faces upward.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | X0 | Analog input channel 0 for X-side multiplexer - connects to selected source when A=0, B=0 |
| 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 |
| 5 | Y0 | Analog input channel 0 for Y-side multiplexer - shares same A/B address as X-side |
| 6 | Y1 | Analog input channel 1 for Y-side multiplexer - enables simultaneous dual-path selection |
| 7 | Y2 | Analog input channel 2 for Y-side multiplexer - supports parallel signal conditioning chains |
| 8 | Y3 | Analog input channel 3 for Y-side multiplexer - isolated from X-side except via shared control |
| 9 | A | LSB address input - determines lower bit of 2-bit channel select for both X and Y muxes |
| 10 | B | MSB address input - determines upper bit of 2-bit channel select for both X and Y muxes |
| 11 | ENABLE | Active-low global enable - drives all switches open when high; required for power-down mode |
| 12 | N.C. | No internal connection - must remain unconnected; no pull-up/down or routing required |
| 13 | GND | Analog/digital ground reference - return path for all signals and supply current |
| 14 | X | Common output for X-side 4:1 mux - carries selected X0–X3 signal bidirectionally |
| 15 | Y | Common output for Y-side 4:1 mux - carries selected Y0–Y3 signal bidirectionally |
| 16 | VCC | Positive supply for analog switches and digital logic - sets analog signal range (0 to VCC) |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility | Fully pin-compatible with industry-standard 74HC4052 and MAX4582 - enables drop-in replacement without PCB redesign |
| Rail-to-rail analog operation | Supports input/output signals from GND to VCC - eliminates clipping in single-supply sensor interfaces |
| Guaranteed on-resistance flatness | ≤1Ω variation across full analog signal range - ensures consistent gain and linearity in amplifier feedback paths |
| Low charge injection | 3pC maximum - minimizes voltage glitch on high-impedance nodes during switching (e.g., sample-and-hold capacitors) |
| High off-isolation | <–93dB at 100kHz - suppresses coupling from inactive channels in RF or audio front-ends |

FAQ
What is the maximum analog signal voltage range supported by the MAX4618CPE+?
The MAX4618CPE+ supports rail-to-rail analog signals from GND to VCC. With a +5.5V supply, this permits input/output voltages from 0V to +5.5V. Absolute maximum ratings restrict analog pins to –0.3V to (VCC + 0.3V); exceeding these clamps via internal ESD diodes and risks damage. The MAX4618CPE+ does not support negative supply rails or bipolar operation unless externally biased.
Does the MAX4618CPE+ require external pull-up resistors on its digital control lines?
No, the MAX4618CPE+ does not require external pull-up resistors on A, B, or ENABLE. Its digital inputs have guaranteed TTL/CMOS-compatible thresholds (2.4V high / 0.8V low at +5V) and draw less than 1µA input current. Microcontroller GPIOs driving 3.3V or 5V logic levels interface directly. Pull-ups are unnecessary and may interfere with fast edge rates needed for 15ns switching.
Can the MAX4618CPE+ be used to switch differential analog signals?
Yes, the MAX4618CPE+ can switch differential signals by using one mux section (e.g., X0–X3/X) for the positive leg and the other (Y0–Y3/Y) for the negative leg, maintaining matched on-resistance (≤1Ω) and timing. However, it does not provide inherent common-mode rejection or integrated differential termination. External matching of trace lengths and impedances is required to preserve signal integrity above 1MHz.
What is the thermal derating behavior of the MAX4618CPE+ in plastic DIP packaging?
The MAX4618CPE+ plastic DIP package has a continuous power dissipation rating of 842mW at +70°C ambient, with derating at 10.53mW/°C above that temperature. At +85°C ambient, maximum allowable power drops to 684mW. This reflects the package's thermal resistance (θJA ≈ 95°C/W); sustained operation near thermal limits requires careful board layout with adequate copper pour and airflow.
Is the MAX4618CPE+ RoHS-compliant and lead-free?
Yes, the MAX4618CPE+ is RoHS-compliant and lead-free, as indicated by the "+" suffix in its part number. It meets EU Directive 2011/65/EU and associated exemptions. The device uses matte tin lead finish and complies with JEDEC J-STD-020 moisture sensitivity level 1 (unlimited floor life at ≤30°C/85% RH), requiring no baking prior to soldering.
