Product details
Overview
MAX336CPI+ from Maxim Integrated is a 16-channel, single-ended CMOS analog multiplexer designed to route one of 16 bidirectional analog inputs (NO1–NO16) to a common output (COM) under 4-bit binary address control (A0–A3). It features 400Ω max on-resistance, <20pA NO-off leakage at +25°C, 3.5pC typical charge injection, and operates from +4.5V to +30V single supply or ±4.5V to ±20V dual supplies. It is used in precision data acquisition systems requiring low signal distortion and rail-to-rail analog handling.
For engineers reviewing the MAX336CPI+ datasheet, MAX336CPI+ pinout, MAX336CPI+ application, or MAX336CPI+ equivalent, key selection criteria include guaranteed low off-leakage (<20pA), tight on-resistance matching (≤10Ω), TTL/CMOS-compatible enable/address inputs, ESD protection >2000V, and compatibility with precision test equipment and signal routing architectures.
Technical Context
The MAX336CPI+ implements a monolithic BiCMOS decoder-switch architecture that supports both multiplexing and demultiplexing functions. Its internal CMOS transmission gates are controlled by a 4-bit address decoder and an active-low enable input (EN), enabling precise channel selection without break-before-make timing gaps exceeding 50ns.
All analog terminals (NO1–NO16, COM) support rail-to-rail signal swing between V− and V+, with guaranteed bidirectional conduction and symmetric on-resistance behavior. Control logic inputs tolerate full-supply-range TTL thresholds (0.8V to 2.4V) across ±4.5V to ±18V supply conditions, ensuring robust interfacing with microcontrollers and FPGA I/O.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | 16-channel single-ended mux - selects one analog input from 16 sources to shared COM output. |
| On-Resistance (max) | 400Ω at TA = +25°C - ensures minimal voltage drop and gain error in precision signal paths. |
| NO-Off Leakage (max) | 0.02nA at +25°C - preserves high-impedance sensor node integrity and measurement accuracy. |
| Charge Injection (typ) | 3.5pC - limits transient voltage kick at COM during channel switching, critical for sample-and-hold stability. |
| Supply Range | +4.5V to +30V single or ±4.5V to ±20V dual - enables operation in industrial, test, and mixed-signal systems with wide voltage rails. |
| Transition Time (max) | 500ns - defines maximum analog path settling time after address change, supporting kHz-rate scanning. |
| ESD Protection | >2000V per Method 3015.7 - provides robust handling during board assembly and system integration without external protection. |
Pinout & Package
MAX336CPI+ is housed in a 28-pin plastic DIP (dual in-line package) with 0.600-inch body width and through-hole mounting. Pin 1 is V+, pin 27 is V−, pin 28 is COM, pins 4–26 carry NO1–NO16 and address/enable signals, and pin 12 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Bias source for internal logic and switch PMOS devices; must be ≥ +4.5V for guaranteed operation. |
| V− | Negative supply input | Reference for NMOS switches and analog signal lower rail; connect to GND for single-supply use. |
| COM | Common analog output | Single bidirectional terminal connected to selected NOx channel; handles rail-to-rail signals up to ±15V. |
| NO1–NO16 | Analog input/output terminals | 16 fully interchangeable, bidirectional analog ports; no dedicated input/output assignment. |
| A0–A3 | Binary address inputs | 4-bit code selects which NOx connects to COM; logic levels compatible with TTL/CMOS over full temperature range. |
| EN | Enable input (active-high) | When low, all switches open; when high, decoding logic activates and selected channel conducts. |
| GND | Logic ground reference | Return path for digital control circuitry; separate from analog signal reference unless using single supply. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail® analog signal handling | Supports input/output voltages from V− to V+ without clipping - essential for full-scale sensor interface and DAC output routing. |
| Guaranteed low charge injection (3.5pC typ) | Minimizes voltage glitch at COM during channel switching - directly improves accuracy in sampling circuits and integrators. |
| Pin-compatible upgrade for DG506 | Direct replacement for industry-standard 16-channel mux without PCB redesign - reduces qualification time in legacy upgrades. |
| Sub-20pA off-leakage at +25°C | Preserves high-Z source integrity in electrometer-grade measurements and piezoelectric sensor conditioning. |
| TTL/CMOS-compatible control inputs | Operates reliably with standard logic families across full supply range - eliminates level-shifter requirements in mixed-voltage systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG506ACJ | Higher 600Ω max on-resistance; no guaranteed charge injection spec; 1500V ESD rating. | Limited to lower-precision, non-critical signal routing where leakage and switching transients are less constrained. | Choose DG506ACJ only if cost sensitivity outweighs precision requirements and existing layout uses same 28-pin DIP footprint. |
| ADG506AKRZ | 440Ω max on-resistance; 25pC max charge injection; -40°C to +85°C temp range; SOIC-28 package. | Better suited for extended-temperature industrial designs but requires PCB rework due to surface-mount packaging. | Select ADG506AKRZ when operating beyond 0°C to +70°C or when SOIC footprint is preferred; verify layout compatibility before substitution. |
Compared with DG506ACJ and ADG506AKRZ, the MAX336CPI+ delivers superior leakage performance (<20pA vs. ~100pA), tighter RON matching (≤10Ω vs. ≤25Ω), and lower charge injection (3.5pC vs. 25pC), making it optimal for high-fidelity data acquisition where signal integrity is non-negotiable.

FAQ
What is the maximum operating temperature range for the MAX336CPI+?
The MAX336CPI+ is rated for operation from 0°C to +70°C ambient temperature. This commercial-grade temperature range is specified in the ordering information table and confirmed in the Absolute Maximum Ratings section. The 'C' suffix in MAX336CPI+ explicitly denotes the 0°C to +70°C grade, distinguishing it from the extended-temperature E-grade (−40°C to +85°C) and military-grade M-grade (−55°C to +125°C) variants. Operation outside this range may result in parametric degradation or functional failure.
Does the MAX336CPI+ support single-supply operation, and what is the minimum voltage?
Yes, the MAX336CPI+ supports single-supply operation with V− connected to GND. The minimum positive supply voltage is +4.5V, as specified in the Electrical Characteristics table under "Power-Supply Range." At +4.5V, the analog signal range is reduced compared to higher supplies (e.g., ±15V), but the device remains fully functional with guaranteed TTL-compatible logic thresholds and on-resistance performance within datasheet limits. Operation below +4.5V is not characterized or guaranteed.
Is the MAX336CPI+ pin-compatible with the DG506, and what does that mean for design reuse?
Yes, the MAX336CPI+ is explicitly described in its datasheet as a "pin-compatible upgrade for the industry-standard DG506." This means identical pin count (28), pinout arrangement (including V+, V−, COM, NO1–NO16, A0–A3, EN, GND), and mechanical footprint (28-pin plastic DIP). No PCB layout changes are required when replacing DG506 with MAX336CPI+, enabling drop-in improvement of leakage, charge injection, and ESD performance without redesign effort or qualification delay.
What is the significance of the '+' suffix in MAX336CPI+?
The '+' suffix in MAX336CPI+ indicates a lead(Pb)-free and RoHS-compliant package, as stated in the datasheet's Ordering Information footnote. This applies to the 28-pin plastic DIP housing and confirms compliance with EU Directive 2011/65/EU. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for through-hole assembly and carries no halogen or antimony restrictions beyond RoHS scope. No special handling or reflow profile is needed beyond standard DIP wave-solder guidelines.
How does the MAX336CPI+ handle bidirectional analog signals, and what are the voltage limits?
The MAX336CPI+ supports fully bidirectional analog signal flow between any NOx pin and the COM pin, with no intrinsic directionality. Voltage limits are rail-to-rail: signals may swing from V− to V+, provided the absolute maximum ratings are observed (e.g., V+ − V− ≤ 44V, and no terminal exceeds V+ + 0.3V or V− − 0.3V). In single-supply mode (V− = GND), the analog range is 0V to V+. In dual-supply mode (e.g., V+ = +15V, V− = −15V), the full ±15V range is supported, enabling true bipolar signal routing without external level-shifting circuitry.
