Product details
Overview
MAX4051CPE+ from Maxim Integrated is an 8-channel CMOS analog multiplexer configured as a single-pole, eight-throw (SP8T) switch with rail-to-rail signal handling, 100Ω typical on-resistance at ±5V, 0.1nA max off-leakage at +25°C, and TTL/CMOS-compatible logic thresholds-used in low-voltage data-acquisition systems for sensor signal routing.
For engineers reviewing the MAX4051CPE+ datasheet, MAX4051CPE+ pinout, MAX4051CPE+ application, or MAX4051CPE+ equivalent, key selection criteria include guaranteed on-resistance match (6Ω), dual-supply operation (±2.7V to ±8V), single-supply compatibility (+2.7V to +16V), low crosstalk (<–90dB), and high off-isolation (<–90dB) in 50Ω systems.
Technical Context
The MAX4051CPE+ implements a CMOS transmission-gate architecture with independent control of eight analog paths via three binary address inputs (ADDA, ADDB, ADDC) and an active-low inhibit (INH). It supports break-before-make switching with 30ns typical transition time and 75ns turn-on time under ±5V supplies.
All analog terminals (COM, NO0–NO7) are bidirectional and interchangeable; internal ESD diodes clamp signals exceeding V+ or V−, and leakage current originates primarily from reverse-biased protection diodes-not signal-path conduction-enabling rail-to-rail operation without ground reference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V - ensures minimal voltage drop and signal attenuation in precision analog paths |
| On-resistance match (∆RON) | 6Ω max (A-suffix) - enables accurate channel-to-channel gain matching in multiplexed instrumentation |
| Off-leakage current | 0.1nA max at +25°C - preserves signal integrity in high-impedance sensor interfaces and sample-hold circuits |
| Supply range | ±2.7V to ±8V dual or +2.7V to +16V single - supports battery-powered and industrial supply rails without level-shifting |
| Crosstalk | <–90dB at 100kHz - prevents interference between active and inactive channels in audio/video routing |
| Off-isolation | <–90dB at 100kHz - blocks signal coupling from powered-off channels into sensitive measurement nodes |
| Logic thresholds | 0.8V to 2.4V - guarantees reliable interface with 5V TTL and CMOS controllers without external translators |
Pinout & Package
MAX4051CPE+ is supplied in a 16-pin plastic DIP package (0°C to +70°C operating range), with through-hole mounting and standard 0.3-inch width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 | Normally open analog switch terminals - selectable as inputs or outputs; interchangeable with COM |
| 3 | COM | Common analog terminal - connects to one selected NOx path when enabled; bidirectional signal path |
| 6 | INH | Digital inhibit input - logic high disables all switches; active-low enable simplifies system-level power gating |
| 7 | V− | Negative analog supply - sets lower rail limit for analog signals; tied to GND for single-supply operation |
| 8 | GND | Digital ground reference - isolates logic circuitry from analog signal paths; no analog return path |
| 9, 10, 11 | ADDA, ADDB, ADDC | Binary address inputs - select one of eight NOx paths (000–111); no internal pull-up/down |
| 16 | V+ | Positive analog/digital supply - powers internal logic and switch gates; defines upper analog signal limit |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Direct drop-in replacement for legacy designs-no PCB or firmware changes required |
| Guaranteed on-resistance flatness | 10Ω max over full analog signal range - maintains consistent gain across input voltage swing |
| Rail-to-rail analog signal handling | VCOM and VNO operate from V− to V+ - eliminates need for signal biasing in bipolar systems |
| Low charge injection | 2pC typical - minimizes voltage glitch in sample-and-hold and ADC front-end applications |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds at +5V supply - interoperable with microcontrollers and FPGAs without level shifters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BNZ | 8-channel CMOS mux; 100Ω RON at ±5V but 10nA off-leakage at +25°C (100× higher than MAX4051CPE+) | Less suitable for high-impedance sensor multiplexing where leakage-induced offset matters | Select MAX4051CPE+ when sub-nA leakage is required; ADG408BNZ acceptable for lower-precision, higher-speed systems |
| 74HC4051D | Pin-compatible logic-level mux; 120Ω RON at +5V, no guaranteed ∆RON or leakage specs, not characterized for analog performance | Not recommended for precision analog routing-lacks guaranteed match, flatness, or leakage specs | MAX4051CPE+ is preferred for production analog signal paths; 74HC4051D only for cost-sensitive, non-critical digital control |
Compared with ADG408BNZ and 74HC4051D, the MAX4051CPE+ delivers superior leakage control (0.1nA vs. 10nA/undefined), guaranteed channel matching (6Ω), and full analog characterization-making it the optimal choice for precision, low-power, and industrial-grade multiplexing where signal fidelity is critical.

FAQ
What is the maximum supply voltage range supported by the MAX4051CPE+?
The MAX4051CPE+ operates with dual supplies from ±2.7V to ±8V or a single supply from +2.7V to +16V. Absolute maximum ratings allow V+ up to +17V and V− down to –17V relative to GND, but continuous operation beyond ±8V or +16V risks permanent damage. For reliable long-term use, stay within the specified functional ranges.
Does the MAX4051CPE+ require a ground connection for analog signal paths?
No-the MAX4051CPE+ has no analog ground reference. Analog signals pass bidirectionally between COM and any NOx pin within the V− to V+ rails. GND serves only the digital logic section; analog paths float independently, enabling true rail-to-rail operation without signal biasing or ground-loop concerns.
How does the on-resistance match specification benefit system design with the MAX4051CPE+?
The MAX4051CPE+ guarantees ≤6Ω on-resistance match (∆RON) between channels-critical for applications like programmable-gain amplifiers or calibrated sensor arrays where gain consistency across multiplexed paths directly impacts measurement accuracy and reduces post-processing calibration overhead.
Can the MAX4051CPE+ be used in single-supply +3V systems?
Yes-the MAX4051CPE+ functions down to +2.7V single supply. At +3V, typical on-resistance rises to 525Ω (max 700Ω), and switching times increase (e.g., tON up to 600ns), but rail-to-rail operation and sub-nA leakage are preserved. Verify timing and RON impact in your specific signal chain before deployment.
Is the MAX4051CPE+ pin-compatible with the industry-standard 74HC4051?
Yes-the MAX4051CPE+ is explicitly designed as a pin- and function-compatible upgrade to the 74HC4051, sharing identical pinout, logic interface, and basic switching behavior. However, it adds guaranteed analog specifications (leakage, RON match, flatness) absent in the HC variant, making it suitable for precision applications where the 74HC4051 falls short.
