Product details
Overview
MAX4051CSE+ 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 channel selection between sensors and ADC inputs.
For engineers reviewing the MAX4051CSE+ datasheet, MAX4051CSE+ pinout, MAX4051CSE+ application, or MAX4051CSE+ equivalent, key selection criteria include guaranteed on-resistance match (12Ω), dual-supply operation (±2.7V to ±8V), single-supply compatibility (+2.7V to +16V), low crosstalk (< –90dB), and pin compatibility with 74HC4051.
Technical Context
The MAX4051CSE+ implements a CMOS transmission-gate architecture with independent V+ and V– supplies defining the analog signal range, enabling true rail-to-rail operation. Its digital control uses ADDA/ADDB/ADDC address lines and INH enable, with logic thresholds fixed at 0.8V (low) and 2.4V (high) under +5V supply-ensuring interoperability with TTL and CMOS logic families without level shifting.
Internal ESD protection diodes connect each NO/COM pin to V+ and V–, limiting analog signal excursion but preserving low leakage (≤0.1nA at +25°C) and high off-isolation (< –90dB). The device guarantees break-before-make timing (≤225ns) and charge injection ≤10pC, critical for precision sampling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and gain error in precision analog paths |
| On-resistance match (∆RON) | 12Ω max - enables accurate ratiometric measurements across channels without calibration |
| Off-leakage current | 0.1nA max at +25°C - preserves high-impedance sensor node integrity and reduces offset drift |
| Supply range | ±2.7V to ±8V dual or +2.7V to +16V single - supports battery-powered and industrial rails without external regulators |
| Crosstalk | < –90dB at 100kHz - prevents signal coupling between active and inactive channels in multi-signal routing |
| Off-isolation | < –90dB at 100kHz - blocks unwanted signal feedthrough from powered-off channels into sensitive receivers |
| Logic thresholds | 0.8V (low), 2.4V (high) - guarantees reliable switching with standard 5V TTL/CMOS microcontrollers and FPGAs |
Pinout & Package
MAX4051CSE+ is housed in a 16-pin narrow SO (Small Outline) package with 1.27mm pitch, JEDEC MS-012AC compliant, 10.2mm × 5.3mm footprint, and exposed pad not present. Pin 1 marked by beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 | Eight normally open analog switch terminals - bidirectional, interchangeable with COM; support rail-to-rail signal routing |
| 3 | COM | Common analog terminal - connects to selected NOx channel; no ground reference; voltage bounded by V+ and V– |
| 6 | INH | Digital inhibit input - logic high disables all switches; tied low for normal operation |
| 7 | V– | Negative analog supply - set to GND for single-supply use; defines lower analog signal limit |
| 8 | GND | Digital ground reference - separate from analog path; required for logic interface stability |
| 9, 10, 11 | ADDA, ADDB, ADDC | 3-bit binary address inputs - select one of eight NOx channels (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 in existing PCB layouts using industry-standard 16-pin SO footprint |
| Rail-to-rail analog signal handling | Supports input/output signals from V– to V+ - eliminates level-shifting circuitry in mixed-supply systems |
| Guaranteed on-resistance flatness | 10Ω max variation over full analog range - maintains consistent gain and linearity across signal swing |
| Low charge injection (≤10pC) | Minimizes voltage glitch on sampled-hold capacitors - critical for high-resolution SAR ADC front-ends |
| TTL/CMOS logic compatibility | Operates reliably with 5V microcontrollers and FPGAs without external level translators |

FAQ
What is the maximum supply voltage rating for MAX4051CSE+?
The MAX4051CSE+ supports dual supplies from ±2.7V to ±8V, with absolute maximum ratings of V+ ≤ +17V and V– ≥ –17V. Exceeding these limits risks permanent damage. For single-supply use, V– must be connected to GND and V+ may range from +2.7V to +16V. Operation at +16V requires verification of thermal dissipation in the 16-pin SO package.
Does MAX4051CSE+ support rail-to-rail analog signal switching?
Yes, MAX4051CSE+ supports rail-to-rail analog signal switching between V– and V+. When V– = 0V (single supply), signals from 0V to V+ pass unattenuated; with dual supplies (e.g., ±5V), signals from –5V to +5V are fully supported. This is enabled by its CMOS transmission-gate structure and independent V+/V– supply pins-no external level shifters needed.
What is the function of the INH pin on MAX4051CSE+?
The INH (Inhibit) pin on MAX4051CSE+ is a digital input that disables all eight analog switches when driven high (≥2.4V). When INH is low (≤0.8V), normal address-controlled switching resumes. It is commonly tied to GND for continuous operation or controlled by a microcontroller GPIO to globally power-down signal paths-reducing system leakage and enabling low-power sleep modes.
Can MAX4051CSE+ be used with a 3.3V logic controller?
Yes, MAX4051CSE+ accepts 3.3V logic levels on ADDA/ADDB/ADDC and INH pins when V+ = +3.3V or higher. Its logic thresholds (0.8V low, 2.4V high) are compatible with 3.3V CMOS outputs. However, analog performance degrades at low V+: RON increases to ~250Ω at +3.3V, and leakage remains within spec. Ensure V– is properly referenced (GND for single supply) and layout minimizes noise coupling.
How does MAX4051CSE+ differ from MAX4051ACSE+?
MAX4051CSE+ is the commercial-grade version (0°C to +70°C), while MAX4051ACSE+ is the extended-grade variant (–40°C to +85°C) with tighter guaranteed specs: 6Ω max on-resistance match (vs. 12Ω), and 0.1nA off-leakage validated at +85°C (vs. specified at +25°C). Both share identical pinout, package, and basic electrical behavior-but MAX4051ACSE+ is required for applications demanding full-temperature-range parametric assurance.
