Product details
Overview
MAX333AEPP+ 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 on-resistance match, and <10pC charge injection. It serves as a rail-to-rail signal path selector in portable test equipment and communications interfaces.
For engineers reviewing the MAX333AEPP+ datasheet, MAX333AEPP+ pinout, MAX333AEPP+ application, or MAX333AEPP+ equivalent, key selection criteria include guaranteed on-resistance flatness (∆3Ω max), break-before-make timing (10ns typical), -40°C to +85°C industrial temperature range, and TTL/CMOS logic compatibility independent of supply voltage.
Technical Context
The MAX333AEPP+ integrates four independent SPDT switches fabricated using Maxim's silicon-gate process, enabling simultaneous control of four analog signal paths with matched conduction characteristics. Its internal level translator supports logic inputs from 0.8V to 2.4V regardless of V+/V- rails, and its rail-to-rail analog handling allows signals from V- to V+ without damage.
Break-before-make switching prevents momentary shorting during state transitions, critical for multiplexed sensor or audio routing. Charge injection (<10pC) and low off-capacitance (5pF) preserve signal integrity in precision sampling and high-frequency applications up to 1MHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRZ | 8-channel single-pole single-throw (SPST), 44Ω on-resistance, no break-before-make guarantee | Higher channel count but lacks SPDT topology and guaranteed B-B-M timing | Select when needing more than 4 switch paths and can tolerate higher on-resistance and undefined switching overlap |
| TS5A3157DCKR | Single SPDT, 0.75Ω typical on-resistance, +1.65V to +5.5V supply only, not rated for -40°C to +85°C | Optimized for low-voltage portable logic-level switching, not industrial bipolar operation | Select for ultra-low on-resistance in 3.3V/5V systems where extended temperature range and high-voltage capability are unnecessary |
Compared with ADG408BRZ and TS5A3157DCKR, the MAX333AEPP+ uniquely delivers quad SPDT functionality with guaranteed break-before-make timing, bipolar supply support up to ±20V, and industrial temperature rating - making it irreplaceable in precision test and telecom infrastructure where signal integrity and ruggedness are non-negotiable.

FAQ
What is the maximum analog signal voltage range supported by the MAX333AEPP+?
The MAX333AEPP+ supports rail-to-rail analog signals from V- to V+, with absolute maximum ratings allowing VCOM, VNO, and VNC to swing between -30V and +30V when referenced to ground. Under bipolar operation (e.g., V+ = +15V, V- = -15V), the full ±15V analog range is usable; under single-supply operation (e.g., V+ = +24V, V- = GND), the range extends from 0V to +24V. This capability is confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables of the official MAX333A datasheet.
Does the MAX333AEPP+ require external level-shifting for TTL/CMOS logic inputs?
No, the MAX333AEPP+ does not require external level-shifting. Its logic inputs are guaranteed TTL- and CMOS-compatible over 0.8V to 2.4V, independent of the analog supply voltages (V+ and V-). This is explicitly stated in the Features section and verified in the Electrical Characteristics table under "Input Voltage Low" (VIL) and "Input Voltage High" (VIH) parameters. The internal level translator ensures reliable switching even when V+ and V- are set to ±20V while logic signals remain at standard 3.3V or 5V levels.
What is the guaranteed on-resistance match between channels for the MAX333AEPP+?
The MAX333AEPP+ guarantees on-resistance matching of less than 2Ω between any two channels under bipolar-supply operation, as documented in the Features list and Electrical Characteristics table. This specification applies across the full operating temperature range (-40°C to +85°C) and analog signal range, and is critical for applications such as precision multiplexing where gain or offset errors must be minimized. The match is not guaranteed under single-supply conditions per Note 4 in the datasheet.
Can the MAX333AEPP+ be used in a single-supply configuration with V- tied to ground?
Yes, the MAX333AEPP+ supports single-supply operation with V- tied to ground, accepting V+ from +10V to +30V. In this mode, analog signals may swing from 0V to V+, and logic inputs retain their 0.8V–2.4V compatibility. The Electrical Characteristics table includes dedicated "Single Supply" rows confirming parameters such as 45Ω max on-resistance, 45ns turn-off time, and 0.25mA positive supply current at V+ = +12V. This configuration is widely used in portable instruments and industrial controllers.
Is the MAX333AEPP+ pin-compatible with the DG211/DG212 or DG403 devices?
The MAX333AEPP+ is specified in the datasheet as an "upgraded replacement for a DG211/DG212 pair or two DG403s", but it is not pin-compatible with those legacy devices. Its 20-pin DIP footprint differs from the 16-pin packages of DG211/DG212 and the 16-pin SOIC of DG403. While functional equivalence exists in quad SPDT operation, PCB layout changes are required. The MAX333AEPP+ pinout - including dedicated N.C. (pin 15), GND (pin 6), and separate V+ (pin 16)/V- (pin 5) - is unique to the MAX333A family and validated in the Pin Configuration and Pin Description sections.
