Product details
Overview
MAX333AEWP+T from Maxim Integrated is a precision quad SPDT CMOS analog switch operating with 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, and rail-to-rail analog signal handling. It serves as a low-leakage, low-distortion signal routing device in test equipment and portable instrumentation.
For engineers reviewing the MAX333AEWP+T datasheet, MAX333AEWP+T pinout, MAX333AEWP+T application, or MAX333AEWP+T equivalent, key selection criteria include guaranteed on-resistance flatness (∆3Ω max), break-before-make timing (10ns typ), -40°C to +85°C operation, and compatibility with TTL/CMOS logic across supply voltages.
Technical Context
The MAX333AEWP+T implements four independent SPDT switches using silicon-gate CMOS technology, with internal level translation enabling logic inputs (0.8V–2.4V) to function independently of supply voltage. Its architecture guarantees matched on-resistance between channels and flat RON over the full analog signal range (V− to V+).
It supports dual-supply operation with strict break-before-make switching (10ns typical), sub-175ns turn-on, and <6nA off-channel leakage at +85°C. Charge injection is tightly controlled at ≤10pC, and ESD tolerance exceeds 2000V per Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance | <35Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On Resistance Match | <2Ω between channels - enables accurate differential or ratiometric measurements |
| Charge Injection | <10pC - reduces glitch-induced errors in sample-and-hold and multiplexed ADC front-ends |
| Supply Range | ±4.5V to ±20V or +10V to +30V - supports wide-range industrial and battery-powered systems |
| Operating Temp | -40°C to +85°C - qualified for extended-temperature industrial and automotive-adjacent applications |
| Logic Compatibility | TTL/CMOS (0.8V–2.4V input threshold) - interoperable with diverse microcontrollers and FPGAs without level shifters |
| Off-Leakage @ +85°C | <6nA - preserves signal integrity in high-impedance sensor interfaces and low-power standby modes |
Pinout & Package
MAX333AEWP+T is housed in a 20-pin Wide SO (SOIC-W) package with exposed pad, optimized for thermal performance and board space efficiency in compact analog signal chains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 10, 11, 20 | Logic Input (IN1–IN4) | Accepts TTL/CMOS-compatible control signals; referenced to GND, independent of supply rails |
| 2, 9, 12, 19 | Normally Open Terminal (NO1–NO4) | Connects to COMx when corresponding INx = logic high; supports rail-to-rail analog swing |
| 3, 8, 13, 18 | Common Pole (COM1–COM4) | Analog signal path hub; handles bidirectional signals from V− to V+ without damage |
| 4, 7, 14, 17 | Normally Closed Terminal (NC1–NC4) | Connected to COMx when INx = logic low; break-before-make prevents short-through during transition |
| 5 | Negative Supply (V−) | Bipolar supply rail; must be connected even in single-supply mode (tie to GND) |
| 6 | GND | Digital ground reference for logic inputs and internal biasing |
| 15 | Not Internally Connected | No internal connection; must be left floating or tied to GND per layout best practice |
| 16 | Positive Supply (V+) | Main power rail; supports up to +30V in single-supply configuration |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | 8-channel single-pole single-throw (SPST), 28Ω typical RON, ±15V supply only, no single-supply support | Lacks quad SPDT topology and rail-to-rail logic compatibility; requires external level shifting for mixed-voltage systems | Choose ADG408BRUZ only when 8:1 multiplexing is required and supply rails are fixed at ±15V. |
| TS5A3157DCKR | Single SPDT, 0.75Ω typical RON, +1.65V to +5.5V supply, 1.5pC charge injection | Lower voltage, lower RON, but not quad-channel; unsuitable for bipolar or >6V analog signal ranges | Choose TS5A3157DCKR for low-voltage, high-speed digital signal routing-not for precision analog switching above 5.5V. |
Compared with ADG408BRUZ and TS5A3157DCKR, the MAX333AEWP+T uniquely combines quad SPDT topology, bipolar/single-supply flexibility, rail-to-rail analog capability, and guaranteed channel matching-making it irreplaceable in multi-channel precision instrumentation requiring wide dynamic range and temperature resilience.

FAQ
What is the maximum analog signal voltage range supported by the MAX333AEWP+T?
The MAX333AEWP+T supports analog signals from V− to V+, with absolute maximum ratings allowing V+–V− ≤ 44V. In bipolar mode (±15V), this yields a ±15.5V usable analog range; in single-supply mode (+12V, V− = GND), it supports 0V to +11V. The MAX333AEWP+T maintains rail-to-rail operation without damage across these conditions, as confirmed in Absolute Maximum Ratings and Electrical Characteristics tables.
Does the MAX333AEWP+T require external pull-up or pull-down resistors on its logic inputs?
No, the MAX333AEWP+T does not require external pull-up or pull-down resistors. Its logic inputs are TTL/CMOS compatible with guaranteed thresholds of 0.8V (VIL) and 2.4V (VIH) across all supply configurations, and input current is specified at ±1.0µA max. This allows direct interfacing with microcontrollers, FPGAs, and logic gates without additional biasing components-verified in the Electrical Characteristics table under "Input Voltage Low/High" and "Input Current" parameters.
Can the MAX333AEWP+T operate reliably at -40°C ambient temperature?
Yes, the MAX333AEWP+T is fully specified and tested over -40°C to +85°C. The "E" grade suffix denotes extended temperature qualification, and electrical characteristics-including on-resistance, leakage current, and switching times-are guaranteed across this range. Data sheet Figures 2 and 5 confirm RON and leakage stability down to -55°C, and the Ordering Information table explicitly lists MAX333AEWP for -40°C to +85°C operation.
What is the significance of "break-before-make" timing in the MAX333AEWP+T?
Break-before-make timing (10ns typical in the MAX333AEWP+T) ensures the normally closed (NC) path opens before the normally open (NO) path closes during switching. This prevents momentary short-circuits between NC and NO terminals-critical in applications like relay replacement, multiplexer guarding, or signal path isolation where cross-conduction could damage downstream circuitry or corrupt measurements. The value is measured and guaranteed per Figure 5 and Electrical Characteristics table.
How does the MAX333AEWP+T achieve rail-to-rail analog signal handling?
The MAX333AEWP+T achieves rail-to-rail analog signal handling through internal level-shifting circuitry and silicon-gate CMOS process design that extends the voltage tolerance of COM, NO, and NC terminals to the full V−–V+ range-regardless of logic input voltage. This is explicitly stated in the General Description ("Logic inputs and switched analog signals can range anywhere between the supply voltages without damage") and verified in Absolute Maximum Ratings (VCOM, VNO, VNC = V− to V+). No external clamping or limiting is required.
