Product details
Overview
MAX333AEWP/GG8 from Maxim Integrated is a precision quad SPDT CMOS analog switch operating on bipolar supplies (±4.5V to ±20V) or single-ended supplies (+10V to +30V), featuring <35Ω on-resistance, <2Ω channel-to-channel match, <10pC charge injection, 175ns turn-on time, and rail-to-rail analog signal handling. It serves in high-accuracy signal routing for portable test equipment and communications interfaces.
For engineers reviewing the MAX333AEWP/GG8 datasheet, MAX333AEWP/GG8 pinout, MAX333AEWP/GG8 application, or MAX333AEWP/GG8 equivalent, this page delivers verified electrical specs, thermal range (-40°C to +85°C), wide SO-20 package details, and real-world switching performance data critical for analog multiplexer, relay replacement, and signal-path isolation designs.
Technical Context
The MAX333AEWP/GG8 implements four independent SPDT switches using silicon-gate CMOS technology with integrated level translation, enabling TTL/CMOS-compatible logic inputs (0.8V–2.4V) regardless of supply voltage. Its break-before-make architecture ensures 10ns typical isolation between NC and NO paths during switching.
It supports rail-to-rail analog signal ranges (V− to V+), maintains flat on-resistance (∆3Ω max) over full signal swing under bipolar operation, and guarantees off-channel leakage <6nA at +85°C-critical for low-error data acquisition and precision instrumentation front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | Bipolar: ±4.5V to ±20V; single: +10V to +30V - enables flexible power architecture in mixed-signal systems |
| On Resistance | <35Ω max (20Ω typ) - minimizes signal attenuation and gain error in precision analog paths |
| On-Resistance Match | <2Ω between channels - ensures matched gain/attenuation across multiplexed sensor or channel banks |
| Charge Injection | <10pC - reduces settling error and glitch energy in sample-and-hold and ADC driver stages |
| Turn-On/Off Time | <175ns / <145ns - supports fast-switching applications like automatic test equipment scan sequencing |
| Operating Temp | -40°C to +85°C - qualified for industrial and extended-temperature embedded instrumentation |
| ESD Rating | >2000V HBM - improves robustness during board handling and system integration |
Pinout & Package
MAX333AEWP/GG8 is housed in a 20-pin Wide SOIC (SO-20W) package with 0.3" body width and standard 0.050" lead pitch. Pin 1 is marked with a notch or dot; pin 6 is GND, pin 5 is V−, pin 16 is V+, and pins 1/10/11/20 are logic inputs (IN1–IN4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 10, 11, 20 | Logic Input (IN1–IN4) | TTL/CMOS-compatible control lines; valid 0.8V–2.4V regardless of V+/V− |
| 2, 9, 12, 19 | Normally Open Terminal (NO1–NO4) | Analog output path closed when corresponding IN = high; rail-to-rail capable |
| 3, 8, 13, 18 | Common Pole (COM1–COM4) | Input analog node shared between NC and NO paths; handles full V− to V+ range |
| 4, 7, 14, 17 | Normally Closed Terminal (NC1–NC4) | Analog output path closed when corresponding IN = low; break-before-make isolated |
| 5 | Negative Supply (V−) | Bipolar negative rail; must be connected even in single-supply mode (tied to GND) |
| 6 | GND | Digital/analog reference ground; decoupling required near V+ and V− pins |
| 15 | Not Internally Connected | No internal bond; must remain unconnected or grounded per layout best practice |
| 16 | Positive Supply (V+) | Main power rail; supports up to +30V in single-supply configuration |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | VCOM, VNO, VNC operate from V− to V+ - eliminates level-shifting circuitry in ±15V or +24V systems |
| Guaranteed flat on-resistance | ∆3Ω max over full analog range - preserves linearity in audio, sensor, and DAC output switching |
| Low quiescent current | <50µA total - extends battery life in portable instruments and handheld test gear |
| Break-before-make timing | 10ns typical open interval - prevents momentary shorting in critical signal routing (e.g., muxing reference voltages) |
| ESD-hardened design | >2000V per MIL-STD-883 Method 3015.7 - reduces field failure risk in unshielded industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | 8-channel single-pole, not quad SPDT; 24Ω on-resistance; no guaranteed channel match spec | Designed for general-purpose multiplexing, not precision matched-path routing | Select only if channel matching and charge injection are non-critical |
| TS5A3159DCKR | Single SPDT, 0.75Ω on-resistance, but only one switch per package; operates to +5.5V only | Targeted at low-voltage portable logic-level switching, not industrial ±15V signal routing | Use only for single-path, low-voltage, high-speed digital signal routing |
Compared with ADG408BRUZ and TS5A3159DCKR, the MAX333AEWP/GG8 uniquely delivers guaranteed channel-matched on-resistance (<2Ω), bipolar ±20V operation, and <10pC charge injection-making it the only option among the three qualified for precision analog multiplexing in industrial test and telecom infrastructure.

FAQ
What is the maximum allowable supply voltage for MAX333AEWP/GG8?
The MAX333AEWP/GG8 supports absolute maximum ratings of V+ to V− ≤ 44V, with bipolar operation up to ±20V and single-supply operation up to +30V. Exceeding these limits risks permanent damage. For reliable long-term operation, use within the specified operating ranges: ±4.5V to ±20V (bipolar) or +10V to +30V (single). The MAX333AEWP/GG8 datasheet confirms derating curves apply above +70°C ambient.
Does MAX333AEWP/GG8 support rail-to-rail analog signal switching?
Yes, the MAX333AEWP/GG8 supports true rail-to-rail analog signal handling: VCOM, VNO, and VNC terminals operate from V− to V+ across the full specified supply range. This capability eliminates external level shifters in ±15V or +24V systems. The MAX333AEWP/GG8 achieves this via internal charge-pump level translation and robust oxide design, validated in Figures 1–4 of its official datasheet.
What is the guaranteed on-resistance match between channels for MAX333AEWP/GG8?
The MAX333AEWP/GG8 guarantees on-resistance matching of less than 2Ω between any two channels under bipolar-supply operation (±4.5V to ±20V), as explicitly stated in the Features section and Electrical Characteristics table. This specification is process-tested and guaranteed-not typical-enabling precise gain/attenuation matching in multi-channel sensor interfaces. The MAX333AEWP/GG8 does not guarantee this match under single-supply conditions.
Can MAX333AEWP/GG8 operate from a single +12V supply?
Yes, the MAX333AEWP/GG8 operates from a single +12V supply with V− tied to GND. In this configuration, analog signals swing from 0V to +12V, and logic inputs remain compatible (0.8V–2.4V). However, on-resistance increases to 45Ω max (vs. 35Ω max in bipolar mode), and channel matching is not guaranteed. The MAX333AEWP/GG8 datasheet Table "ELECTRICAL CHARACTERISTICS-Single Supply" validates this behavior.
What is the ESD rating for MAX333AEWP/GG8 and how is it tested?
The MAX333AEWP/GG8 has an ESD rating greater than 2000V per MIL-STD-883 Method 3015.7 (Human Body Model), as confirmed in both the General Description and Features sections. This rating applies to all pins including V+, V−, COM, NO, NC, IN, and GND. The MAX333AEWP/GG8 achieves this via on-chip protection diodes and optimized I/O cell design, making it suitable for assembly environments without full ESD flooring.
