Product details
Overview
MAX4051ESE+TG002 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 MAX4051ESE+TG002 datasheet, MAX4051ESE+TG002 pinout, MAX4051ESE+TG002 application, or MAX4051ESE+TG002 equivalent, key selection criteria include guaranteed on-resistance match (6Ω), single-supply operation down to +2.7V, dual-supply range (±2.7V to ±8V), and compatibility with 74HC4051-based layouts.
Technical Context
The MAX4051ESE+TG002 implements a CMOS transmission-gate architecture with independent V+ and V− supplies defining analog signal swing limits; internal logic-level translators convert TTL/CMOS inputs into full-rail gate drive signals without ground reference for analog paths. Its three supply pins (V+, V−, GND) isolate digital control from analog signal domains.
It features break-before-make switching (30ns typical), low charge injection (2pC), and high off-isolation (<−90dB at 100kHz). Signal routing is controlled via three address bits (ADDA, ADDB, ADDC) and an active-high INH inhibit input that disables all channels simultaneously.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel analog multiplexer (SP8T), single COM–NO0 to NO7 path per selection |
| On-resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and gain error in precision sensor interfaces |
| On-resistance match (∆RON) | 6Ω max (A-suffix) - enables accurate ratiometric measurements across channels without calibration |
| Off-leakage current | 0.1nA max at +25°C - preserves high-impedance node integrity in battery-powered front-ends |
| Supply range | Single: +2.7V to +16V; Dual: ±2.7V to ±8V - supports portable, industrial, and mixed-signal systems |
| Logic compatibility | 0.8V to 2.4V thresholds at +5V - interoperates directly with 5V TTL and CMOS microcontrollers |
| Off-isolation | <−90dB at 100kHz (50Ω) - prevents crosstalk between inactive channels in audio/video routing |
Pinout & Package
MAX4051ESE+TG002 is housed in a 16-pin narrow SO (SOIC-N) package, 3.9mm width, with standard 1.27mm pitch and gull-wing leads - compatible with automated SMT assembly and IPC Class 2/3 reflow profiles.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO2 | Normally open analog terminal for channel 2; bidirectional signal path with COM |
| 2 | NO1 | Normally open analog terminal for channel 1; interchangeable with NOx/NCx/COM per datasheet note |
| 3 | NO0 | Normally open analog terminal for channel 0 - default selected path when ADDA=ADDB=ADDC=0 |
| 4 | NO3 | Normally open analog terminal for channel 3; routed to COM when address = 011b |
| 5 | ADDA | LSB address input (A0); controls bit 0 of 3-bit binary channel select (0–7) |
| 6 | ADDB | Address input (A1); together with ADDA and ADDC, selects one of eight NO paths |
| 7 | ADDC | MSB address input (A2); required for full 8-channel decoding (not present on MAX4052) |
| 8 | NO4 | Normally open analog terminal for channel 4; enabled when address = 100b |
| 9 | NO6 | Normally open analog terminal for channel 6; enabled when address = 110b |
| 10 | COM | Common analog terminal - sole I/O port shared across all eight NO channels |
| 11 | NO7 | Normally open analog terminal for channel 7; highest-numbered path, selected at 111b |
| 12 | NO5 | Normally open analog terminal for channel 5; enabled when address = 101b |
| 13 | INH | Digital inhibit input - logic high forces all switches OFF regardless of address state |
| 14 | V− | Negative analog supply rail - tied to GND for single-supply operation (+2.7V to +16V) |
| 15 | GND | Digital ground reference only; no analog signal reference - analog signals float between V+ and V− |
| 16 | V+ | Positive analog/digital supply rail - powers internal logic translators and switch driver stages |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Drop-in replacement in existing 74HC4051 layouts without PCB revision - same pinout and logic interface |
| Rail-to-rail analog signal handling | Supports input/output signals from V− to V+ - enables full dynamic range utilization in ±5V or +5V systems |
| Guaranteed 6Ω on-resistance match | Ensures ≤0.5% gain mismatch across channels - critical for multi-sensor scanning without per-channel calibration |
| Low 2pC charge injection | Minimizes voltage glitch on high-Z nodes (e.g., sample-hold capacitors), preserving ADC accuracy |
| −90dB off-isolation at 100kHz | Suppresses coupling from active to inactive channels - essential for clean audio routing and RF-adjacent signal paths |
| TTL/CMOS logic thresholds | Valid 0.8V/2.4V thresholds at +5V supply - eliminates need for level shifters when interfacing with 3.3V/5V MCUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4051ACSE | Same die, 0°C to +70°C temp grade (vs. −40°C to +85°C for ESE); identical electrical specs and pinout | Suitable for commercial-grade equipment only; not rated for extended industrial temperature operation | Select MAX4051ESE+TG002 for designs requiring −40°C startup or sustained +85°C operation. |
| ADG408BRUZ | 8-channel CMOS mux with 45Ω RON (±15V), but higher 10nA off-leakage at +25°C and no A-suffix match guarantee | Preferred where lower on-resistance is critical and leakage tolerance >10× higher than MAX4051ESE+TG002 | Choose ADG408BRUZ only if system can accommodate 100× higher off-leakage and requires tighter RON spec. |
Compared with MAX4051ACSE, MAX4051ESE+TG002 delivers extended temperature reliability without electrical trade-offs; versus ADG408BRUZ, it offers superior leakage performance and guaranteed channel matching at the cost of slightly higher RON - ideal for precision, low-power, wide-temp applications.

FAQ
What is the operating temperature range for MAX4051ESE+TG002?
The MAX4051ESE+TG002 is rated for −40°C to +85°C operation, verified across all electrical parameters including on-resistance, leakage, and switching times. This industrial temperature grade ensures reliable performance in automotive cabin modules, outdoor IoT sensors, and factory-floor PLCs where ambient extremes are common. The device maintains 0.1nA off-leakage compliance at +25°C and 5nA at +85°C per datasheet specifications.
Can MAX4051ESE+TG002 operate from a single 3.3V supply?
Yes, MAX4051ESE+TG002 supports single-supply operation from +2.7V to +16V. At +3.3V, it delivers ~250Ω typical on-resistance and retains full logic compatibility (VIH = 2.4V, VIL = 0.8V), making it suitable for direct interfacing with 3.3V microcontrollers. However, on-resistance increases and switching speed decreases relative to ±5V operation - verify timing margins using tON/tOFF values from the +3V supply table in the datasheet.
Is MAX4051ESE+TG002 pin-compatible with the 74HC4051?
Yes, MAX4051ESE+TG002 is fully pin-compatible with the industry-standard 74HC4051 - sharing identical 16-pin SOIC-N pinout, address/control logic (ADDA, ADDB, ADDC, INH), and COM/NO terminal assignments. This allows drop-in replacement without PCB modification, while delivering superior specs: lower leakage (0.1nA vs. ~100nA), tighter RON match (6Ω vs. unguaranteed), and extended supply range.
What is the maximum analog signal voltage range supported by MAX4051ESE+TG002?
The MAX4051ESE+TG002 supports rail-to-rail analog signals from V− to V+. With ±5V supplies, this means −5V to +5V; with +5V/V− = GND, the range is 0V to +5V. Absolute maximum ratings allow V+ up to +17V and V− down to −17V, but analog signal excursion must remain within V− and V+ to avoid forward-biasing internal ESD diodes. Exceeding these rails risks increased leakage or latch-up.
Does MAX4051ESE+TG002 require external pull-up or pull-down resistors on address lines?
No, MAX4051ESE+TG002 does not require external biasing on ADDA, ADDB, ADDC, or INH - its digital inputs have defined TTL/CMOS thresholds (0.8V low, 2.4V high at +5V) and low input current (±1µA). Microcontroller GPIOs or logic gates can drive them directly. However, floating address lines must be avoided: uncontrolled states may cause unintended channel selection or partial turn-on, risking signal corruption or increased supply current.
