Product details
Overview
The MAX333AEUP+ 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 max on-resistance, <2Ω channel-to-channel matching, 10pC max charge injection, 145ns max turn-off time, and rail-to-rail analog signal handling-ideal for test equipment signal routing and portable instrumentation multiplexing.
For engineers reviewing the MAX333AEUP+ datasheet, MAX333AEUP+ pinout, MAX333AEUP+ application, or MAX333AEUP+ equivalent, key selection criteria include guaranteed on-resistance flatness (∆3Ω max), break-before-make timing (10ns typical), ESD robustness (>2000V), and compatibility with TTL/CMOS logic across full supply range without level shifters.
Technical Context
The MAX333AEUP+ implements four independent SPDT switches using silicon-gate CMOS process, supporting both bipolar and single-supply operation with logic inputs referenced to ground and analog signals spanning V− to V+. Its architecture guarantees matched on-resistance between channels and flat RON over the full analog signal range under bipolar conditions.
Break-before-make switching prevents momentary shorting during state transitions, critical in high-precision signal paths. Charge injection is tightly controlled (<10pC) to minimize transient errors in sampled-data systems, while off-isolation (72dB) and crosstalk (78dB) support clean multi-channel signal integrity at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance | 35Ω max - ensures minimal signal attenuation and gain error in precision analog paths |
| On Resistance Match | <2Ω between channels - enables accurate differential or ratiometric measurements |
| Charge Injection | 10pC max - limits voltage glitch on sampling capacitors in data acquisition systems |
| Turn-Off Time | 145ns max - supports fast channel switching in automated test equipment |
| Analog Signal Range | V− to V+ - allows rail-to-rail input/output without clamping or distortion |
| ESD Rating | >2000V HBM - provides robust handling during board assembly and field service |
| Supply Range | ±4.5V to ±20V or +10V to +30V - enables flexible power architecture in mixed-signal systems |
Pinout & Package
The MAX333AEUP+ is housed in a 20-pin TSSOP package (4.4mm × 6.5mm, 0.65mm pitch) with exposed pad for thermal enhancement and mechanical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 10, 11, 20 | Logic Input (IN1–IN4) | TTL/CMOS-compatible control lines; valid at 0.8V–2.4V regardless of supply voltage |
| 2, 9, 12, 19 | Normally Open Terminal (NO1–NO4) | Analog output path closed when corresponding IN = high; handles full V− to V+ range |
| 3, 8, 13, 18 | Common Pole (COM1–COM4) | Input node shared between NC and NO paths; must remain within supply rails |
| 4, 7, 14, 17 | Normally Closed Terminal (NC1–NC4) | Analog output path closed when corresponding IN = low; no internal connection to GND |
| 5 | Negative Supply (V−) | Bipolar negative rail; connect to GND for single-supply operation |
| 6 | GND | Digital ground reference for logic inputs and substrate bias |
| 15 | Not Internally Connected | No internal bond; must be left floating or tied to GND per layout best practice |
| 16 | Positive Supply (V+) | Primary power rail; supports up to +30V in single-supply mode |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports VCOM, VNO, VNC from V− to V+ - eliminates external level-shifting circuitry |
| Guaranteed RON flatness | ∆3Ω max over full analog signal range - preserves linearity in precision gain/attenuation stages |
| Low quiescent current | <50µA total - extends battery life in portable instruments and handheld testers |
| Break-before-make timing | 10ns typical - prevents signal shorting during channel reconfiguration in multiplexed front-ends |
| ESD-hardened design | >2000V per MIL-STD-3015.7 - reduces field failure risk in unshielded test environments |

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 monolithic switch; 44Ω max RON; requires dual ±15V or single +12V; no guaranteed RON match spec | Higher channel count but no SPDT topology; less suitable for differential or bidirectional signal routing | Select when needing more than 4 SPDT paths or tighter package footprint; verify RON matching separately |
| TS5A3157DCUR | Single SPDT; 0.75Ω typical RON; operates at +1.65V to +5.5V only; 10nA leakage at +85°C vs. 6nA for MAX333AEUP+ | Optimized for low-voltage portable logic-level switching-not rated for ±20V or rail-to-rail analog signals | Choose only for battery-powered 3.3V/5V digital signal routing; not a functional replacement for high-voltage analog paths |
Compared with ADG408BRUZ and TS5A3157DCUR, the MAX333AEUP+ uniquely delivers guaranteed SPDT channel matching, bipolar ±20V capability, and rail-to-rail analog performance-making it irreplaceable in precision test and industrial signal routing where voltage range and matching accuracy are non-negotiable.

FAQ
What is the maximum allowable supply voltage for MAX333AEUP+?
The MAX333AEUP+ supports absolute maximum ratings of V+ to V− ≤ 44V, with V+ up to +30V and V− down to −30V. For reliable operation, use bipolar supplies from ±4.5V to ±20V or single-ended supplies from +10V to +30V. Exceeding these ranges risks permanent damage, as confirmed in the Absolute Maximum Ratings table of the official datasheet.
Does MAX333AEUP+ support rail-to-rail analog signal switching?
Yes, the MAX333AEUP+ supports rail-to-rail analog signal handling: VCOM, VNO, and VNC terminals operate from V− to V+ without clipping or distortion. This is explicitly guaranteed in the Electrical Characteristics tables and enables direct interfacing with op-amps, ADCs, and DACs without external level-shifting circuitry.
What is the guaranteed on-resistance matching between channels for MAX333AEUP+?
The MAX333AEUP+ guarantees on-resistance matching of less than 2Ω between any two channels under bipolar supply conditions (±4.5V to ±20V), as specified in the Features section and Electrical Characteristics table. This matching is not guaranteed under single-supply operation per Note 4 in the datasheet.
Can MAX333AEUP+ be used with TTL/CMOS logic inputs at any supply voltage?
Yes, the MAX333AEUP+ logic inputs are TTL- and CMOS-compatible across its full supply range, with guaranteed VIH = 2.4V min and VIL = 0.8V max regardless of V+ or V− voltage. This allows direct interfacing with 3.3V or 5V microcontrollers without level translators, as verified in the Logic Input section of the datasheet.
Is the MAX333AEUP+ pin-compatible with older MAX333A variants like MAX333ACUP?
Yes, the MAX333AEUP+ shares identical 20-pin TSSOP pinout and footprint with MAX333ACUP and other MAX333A variants (e.g., MAX333AEWP, MAX333AEPP). The only differences are temperature grade (−40°C to +85°C vs. 0°C to +70°C) and minor parametric shifts-no PCB redesign is required when upgrading from AC-grade to AE-grade devices.
