Product details
Overview
MAX4051CSE+T 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 ADCs.
For engineers reviewing the MAX4051CSE+T datasheet, MAX4051CSE+T pinout, MAX4051CSE+T application, or MAX4051CSE+T equivalent, key selection criteria include guaranteed on-resistance matching (≤6Ω), dual-supply operation (±2.7V to ±8V), single-supply compatibility (+2.7V to +16V), low crosstalk (<–90dB), and SOIC-16 package compatibility with industry-standard 74HC4051 layouts.
Technical Context
The MAX4051CSE+T implements a CMOS transmission-gate architecture with independent control of eight analog paths via three address bits (ADDA, ADDB, ADDC) and an active-low inhibit input (INH). Its internal logic-level translators isolate digital control signals from analog supply rails (V+, V−), enabling robust operation across bipolar and single-supply configurations.
Each switch exhibits symmetrical conduction-NO and COM pins are functionally interchangeable-and supports bidirectional analog signal routing without polarity constraints. The device guarantees break-before-make timing (≤75ns) and charge injection ≤10pC, critical for precision sampling applications where signal integrity must be preserved during switching transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V - ensures minimal voltage drop and gain error in precision signal paths |
| On-resistance match | 6Ω max - enables consistent channel-to-channel gain and offset in multi-sensor systems |
| Off-leakage current | 0.1nA max at +25°C - preserves high-impedance sensor node accuracy over time |
| Supply range | ±2.7V to ±8V dual or +2.7V to +16V single - supports battery-powered and industrial rail-flexible designs |
| Crosstalk | <–90dB at 100kHz - prevents interference between active and inactive channels in dense routing |
| Logic thresholds | 0.8V to 2.4V - ensures reliable interface with 3.3V/5V microcontrollers without level-shifting |
| Turn-on time | 175ns max - enables fast multiplexing in real-time data acquisition up to ~5MHz effective rate |
Pinout & Package
MAX4051CSE+T is housed in a 16-pin narrow SOIC (SO) package, 3.9mm width, with standard JEDEC MS-012AC outline and 1.27mm pitch. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 | Normally open analog terminals - selectable inputs/outputs; electrically identical to COM |
| 3 | COM | Common analog terminal - connects to one NO pin per address state; bidirectional signal path |
| 6 | INH | Digital inhibit - logic high disables all switches; pulled low for normal operation |
| 7 | V− | Negative analog supply - tied to GND for single-supply use; sets lower analog signal limit |
| 8 | GND | Digital ground reference - separate from analog signal reference; no direct connection to analog path |
| 9, 10, 11 | ADDA, ADDB, ADDC | Binary address inputs - select one of eight NO paths to connect to COM (000 = NO0, 111 = NO7) |
| 16 | V+ | Positive analog/digital supply - powers internal logic and switch gates; sets upper analog signal limit |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Direct drop-in replacement in existing PCB layouts using SOIC-16 footprints |
| Rail-to-rail analog signal handling | Supports full V− to V+ swing - eliminates clipping in ±5V or +3.3V systems with grounded references |
| Guaranteed on-resistance flatness | ≤10Ω variation over full analog range - maintains linearity in audio and instrumentation amplifiers |
| Low distortion | <0.04% THD at 600Ω load - preserves fidelity in audio routing and sensor signal chains |
| High off-isolation | <–90dB at 100kHz - suppresses coupling between adjacent channels in high-density multiplexers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4051ACSE+ | Characterized for tighter on-resistance match (6Ω vs. 12Ω) and lower leakage (0.1nA vs. 1nA at +25°C) | Required for high-precision metrology or medical-grade sensor multiplexing where channel matching is critical | Select MAX4051ACSE+ when RON matching ≤6Ω and sub-0.5nA leakage are mandatory; MAX4051CSE+ suffices for general-purpose industrial use. |
| 74HC4051D,653 | No guaranteed RON match or flatness; higher typical on-resistance (120Ω); no A-grade leakage specs | Suitable only for non-critical audio or digital signal routing where leakage and matching are not design constraints | Choose 74HC4051D,653 only for cost-sensitive consumer applications with relaxed analog performance requirements. |
Compared with MAX4051ACSE+ and 74HC4051D,653, the MAX4051CSE+ delivers verified 12Ω RON matching and 1nA off-leakage-striking a balance between precision and cost for industrial data acquisition where A-grade specs are unnecessary but baseline CMOS switch reliability is essential.

FAQ
What is the maximum supply voltage rating for MAX4051CSE+T?
The MAX4051CSE+T has absolute maximum ratings of V+ = –0.3V to +17V and V− = +0.3V to –17V, with V+ to V− differential limited to +17V. For reliable operation, use dual supplies within ±2.7V to ±8V or single supply from +2.7V to +16V. Exceeding these ranges risks permanent damage due to internal ESD diode conduction.
Does MAX4051CSE+T support true bidirectional analog signal flow?
Yes, the MAX4051CSE+T supports fully bidirectional signal routing: NO and COM pins are electrically identical and interchangeable. Signals pass with equal on-resistance and distortion in either direction, making it suitable for both input multiplexing and output demultiplexing in analog signal chains.
What is the guaranteed on-resistance match specification for MAX4051CSE+T?
The MAX4051CSE+T guarantees a maximum on-resistance match (∆RON) of 12Ω between any two channels under ±5V supply conditions at +25°C. This value reflects the difference between highest and lowest RON across all eight NO paths, ensuring predictable gain consistency in multi-channel measurement systems.
Can MAX4051CSE+T operate from a +3.3V single supply?
Yes, the MAX4051CSE+T operates from +3.0V to +3.6V single supply (V− = GND). At +3.3V, typical on-resistance rises to ~525Ω, and turn-on time increases to ~300ns-but all logic thresholds, leakage specs, and rail-to-rail analog range remain valid, supporting low-power IoT sensor hubs.
Is MAX4051CSE+T pin-compatible with the 74HC4051?
Yes, the MAX4051CSE+T is pin-compatible with the industry-standard 74HC4051 in SOIC-16 packages. Pin assignments for V+, GND, INH, ADDA–ADDC, COM, and NO0–NO7 match exactly-enabling direct substitution without PCB changes, though electrical performance (leakage, RON match, distortion) exceeds the HC variant.
