Product details
Overview
MAX333AEAP+T 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 max on-resistance, <2Ω channel-to-channel match, 10pC max charge injection, 145ns max turn-off time, and rail-to-rail analog signal handling. It serves as a low-leakage, low-distortion switching solution in portable test equipment and communications interfaces.
For engineers reviewing the MAX333AEAP+T datasheet, MAX333AEAP+T pinout, MAX333AEAP+T application, or MAX333AEAP+T equivalent, key selection criteria include guaranteed on-resistance flatness (∆3Ω max), break-before-make timing (10ns typical), ESD tolerance (>2000V), and compatibility with TTL/CMOS logic across supply ranges - critical for high-accuracy signal routing in battery-powered and industrial systems.
Technical Context
The MAX333AEAP+T integrates four independent SPDT switches fabricated using Maxim's silicon-gate process, enabling precise analog signal routing without distortion. Its architecture guarantees matched on-resistance (<2Ω) and flat on-resistance (∆3Ω max) over full signal range under bipolar operation - essential for multi-channel instrumentation where gain/phase tracking matters.
Logic inputs are fully compatible with TTL/CMOS thresholds (0.8V–2.4V) regardless of supply voltage, and analog terminals tolerate voltages from V− to V+, supporting rail-to-rail signal switching. Break-before-make operation prevents momentary shorting during state transitions, with 10ns typical open interval and sub-175ns switching times - suitable for fast multiplexing in automated test systems.
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 channel-to-channel signal balancing in differential or multi-path systems |
| Charge Injection | 10pC max - reduces glitch-induced settling errors in sample-and-hold or ADC front-end circuits |
| Turn-Off Time | 145ns max - supports high-speed multiplexing up to ~3MHz without inter-channel crosstalk buildup |
| Supply Range | ±4.5V to ±20V or +10V to +30V - allows flexible power architecture in mixed-signal systems with legacy or custom rails |
| ESD Rating | >2000V HBM - provides robust handling during board assembly and field service without external protection |
| Off-Leakage Current | 6nA max at +85°C - preserves signal integrity in high-impedance sensor interfaces and battery-monitoring circuits |
Pinout & Package
MAX333AEAP+T is housed in a 20-pin TSSOP package (JEDEC MO-153, 6.5mm × 4.4mm, 0.65mm pitch), optimized for space-constrained portable and test applications. Thermal performance supports 559mW continuous dissipation at +70°C with 7mW/°C derating above that temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1,10,11,20) | Logic control inputs | TTL/CMOS-compatible digital signals selecting NO or NC path per channel |
| COM1–COM4 (Pins 3,8,13,18) | Analog common terminals | Rail-to-rail capable input/output nodes accepting signals from V− to V+ |
| NO1–NO4 (Pins 2,9,12,19) | Normally open analog outputs | Connected to COMx when corresponding INx = logic high; isolated otherwise |
| NC1–NC4 (Pins 4,7,14,17) | Normally closed analog outputs | Connected to COMx when corresponding INx = logic low; isolated otherwise |
| V+ (Pin 16) | Positive supply | Accepts +10V to +30V (single) or +4.5V to +20V (bipolar positive rail) |
| V− (Pin 5) | Negative supply | Accepts −4.5V to −20V (bipolar negative rail); tie to GND for single-supply use |
| GND (Pin 6) | Ground reference | System ground return for logic and internal bias circuitry |
| N.C. (Pin 15) | No internal connection | Unused pad; must be left floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full V− to V+ signal swing without clipping or distortion - critical for ±10V instrumentation inputs |
| Break-before-make switching | 10ns typical open interval prevents signal shorting during transition - avoids transient glitches in audio or sensor muxing |
| Guaranteed on-resistance flatness | ∆3Ω max variation across entire analog signal range - maintains consistent gain/attenuation in precision gain-setting networks |
| Low quiescent current | <50µA total supply current - extends battery life in handheld test gear and portable medical devices |

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; 44Ω on-resistance; no guaranteed channel matching | Requires re-mapping of control logic and PCB layout; lacks break-before-make guarantee | Use only if channel count flexibility outweighs precision matching and timing requirements |
| TS5A3157DCKR | Single SPDT, 0.75Ω typical on-resistance; 5V-only supply; 30pC charge injection | Not functionally equivalent - requires four separate ICs and additional logic for quad operation | Select only for ultra-low-RON in low-voltage, single-channel designs where size and cost dominate precision specs |
Compared with ADG408BRUZ and TS5A3157DCKR, the MAX333AEAP+T uniquely delivers guaranteed quad SPDT topology with matched on-resistance, break-before-make timing, and wide supply flexibility - making it the only drop-in solution for high-fidelity, multi-channel analog routing in industrial and test environments.

FAQ
What is the operating temperature range for MAX333AEAP+T?
The MAX333AEAP+T is rated for −40°C to +85°C ambient operation, validated across all electrical specifications including on-resistance match, leakage current, and switching speed. This extended range supports deployment in industrial control panels, outdoor telecom cabinets, and portable test gear exposed to environmental extremes - unlike the commercial-grade MAX333ACUP variant limited to 0°C to +70°C.
Can MAX333AEAP+T operate from a single +12V supply?
Yes, MAX333AEAP+T supports single-supply operation from +10V to +30V. When using +12V, connect V− to GND. Under this configuration, analog signals can swing from 0V to +12V, and logic inputs remain compatible with standard TTL/CMOS thresholds. Note that on-resistance increases to 75Ω max and turn-off time degrades to 45ns - both specified in the single-supply electrical characteristics table.
Does MAX333AEAP+T require external charge pump or level-shifting circuitry?
No, MAX333AEAP+T does not require external charge pumps or level shifters. Its internal silicon-gate architecture enables full rail-to-rail analog switching and TTL/CMOS logic compatibility directly from V+ and V− supplies. The device integrates all necessary biasing and level translation - confirmed by the "LEVEL TRANSLATOR (2-CHANNEL)" block shown in the typical operating circuit diagram.
How is break-before-make timing verified for MAX333AEAP+T?
Break-before-make timing for MAX333AEAP+T is characterized at 10ns typical using the test circuit in Figure 5 of the datasheet, with V+ = +16.5V, V− = −16.5V, and RGEN = 0Ω. This parameter is guaranteed across temperature and supply variations and ensures no overlap between NC and NO conduction states - critical for preventing momentary shorts in sensitive analog signal paths.
Is MAX333AEAP+T pin-compatible with older MAX333A variants like MAX333AEPP?
Yes, MAX333AEAP+T shares identical pinout and functionality with other MAX333AE_ _ variants (e.g., MAX333AEPP, MAX333AEWP), differing only in package type - TSSOP vs. plastic DIP vs. wide SO. All share the same 20-pin layout, terminal functions, and electrical behavior, enabling direct PCB footprint reuse when upgrading from through-hole to surface-mount assembly.
