Product details
Overview
MAX336EAI 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, and 3.5pC typical charge injection-enabling precision signal routing in data acquisition systems operating from ±4.5V to ±20V dual supplies or +4.5V to +30V single supply.
For engineers reviewing the MAX336EAI datasheet, MAX336EAI pinout, MAX336EAI application, or MAX336EAI equivalent, key selection criteria include rail-to-rail analog signal handling (±15V), TTL/CMOS-compatible digital inputs across full temperature range (–40°C to +85°C), guaranteed low off-leakage for high-impedance sensor interfaces, and ESD protection >2000V per Method 3015.7.
Technical Context
The MAX336EAI implements a monolithic BiCMOS decoder-driver architecture that enables break-before-make switching with 10ns to 50ns tOPEN, ensuring no signal shorting during channel transitions. Its analog switches operate bidirectionally with matched on-resistance (≤10Ω ΔRON) and rail-to-rail signal capability-supporting input/output voltages from V– to V+ without clipping.
Digital control logic accepts TTL/CMOS levels (0.8V to 2.4V) across the full –40°C to +85°C industrial temperature range and ±4.5V to ±18V supply span. Enable (EN) and address (A0–A3) inputs are internally clamped, and all analog terminals tolerate overvoltage up to (V– – 0.3V) and (V+ + 0.3V) via integrated diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | 16-channel single-ended mux: selects one of 16 analog inputs to shared COM output |
| On-Resistance (max) | 400Ω at TA = +25°C, VCOM = ±10V - ensures minimal signal attenuation and gain error in precision amplification paths |
| NO-Off Leakage (max) | 0.02nA at +25°C - preserves integrity of high-impedance sensor outputs and integrator nodes |
| Charge Injection (typ) | 3.5pC - limits voltage glitch on sampled-hold capacitors, critical for ADC front-end accuracy |
| Supply Range | +4.5V to +30V single supply or ±4.5V to ±20V dual supply - supports industrial ±15V and automotive 24V systems |
| Transition Time (max) | 500ns - enables multiplexing of signals up to ~1MHz without significant edge distortion |
| ESD Protection | >2000V per Method 3015.7 - reduces need for external protection in test equipment and field-deployed instruments |
Pinout & Package
MAX336EAI is housed in a 28-pin SSOP (Shrink Small Outline Package) with 0.635mm pitch and RoHS-compliant lead-free finish (+ suffix). The package measures 10.2mm × 5.3mm × 1.95mm and is optimized for automated surface-mount assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply voltage input | Accepts +4.5V to +30V; powers internal logic and switch driver stages |
| V− | Negative supply voltage input | Accepts –4.5V to –20V; connects to GND for single-supply operation |
| GND | Logic ground reference | Reference for TTL/CMOS input thresholds and internal bias generation |
| COM | Common analog output terminal | Bidirectional node connected to selected NOx channel; handles rail-to-rail signals |
| NO1–NO16 | Analog input terminals | 16 bidirectional, interchangeable analog ports; each electrically identical to COM |
| A0–A3 | Binary address inputs | 4-bit code selects active channel (0–15); TTL/CMOS compatible over full temp/supply range |
| EN | Enable input | Active-high logic control: EN = 0 disables all switches (high-Z state); EN = 1 enables decoding |
| N.C. | No internal connection | Pins 2, 3, 13 - unused; must be left floating or tied to GND for mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail® analog signal handling | Supports VNO/VCOM from V− to V+ - eliminates level-shifting in ±15V op-amp signal chains |
| Guaranteed low charge injection | 3.5pC typical - minimizes sampling error in precision data acquisition and sample-and-hold circuits |
| Matched on-resistance | ≤10Ω difference between any two channels at +25°C - ensures consistent gain and offset across multiplexed channels |
| Plug-in upgrade for DG506 | PIN-compatible replacement for industry-standard DG506 - allows drop-in redesign without PCB changes |
| Bidirectional current conduction | Equal RON and leakage in both directions - enables use as mux or demux in analog signal distribution networks |

FAQ
What is the maximum allowable supply voltage for MAX336EAI?
The MAX336EAI supports a single positive supply from +4.5V to +30V or dual supplies from ±4.5V to ±20V. Absolute maximum ratings specify V+ to V− differential up to 44V, with individual supply pins rated to –0.3V to +44V referenced to V−. Exceeding these limits risks permanent damage.
Does MAX336EAI support rail-to-rail analog signal operation?
Yes, the MAX336EAI supports true rail-to-rail analog signal handling: analog inputs and outputs (NO1–NO16 and COM) operate from V− to V+ without clipping. This is confirmed in the Electrical Characteristics table under "Analog Signal Range" (±15V with ±15V supplies) and applies across the full –40°C to +85°C temperature range.
Is MAX336EAI pin-compatible with the DG506 series?
Yes, the MAX336EAI is explicitly documented as a pin-compatible upgrade for the DG506 and DG507. Pin assignments, package outline, and functional behavior match exactly-enabling direct replacement without PCB layout modification, while delivering improved on-resistance, leakage, charge injection, and ESD protection.
What is the typical charge injection value for MAX336EAI, and why does it matter?
The MAX336EAI has a typical charge injection of 3.5pC, measured with CL = 100pF and RS = 0Ω. This parameter directly impacts voltage glitch magnitude on sampling capacitors in data acquisition systems: ΔV = Q/CL. At 3.5pC and 100pF, the glitch is 35mV-critical for maintaining accuracy in 16-bit+ ADC front-ends where sub-LSB errors are unacceptable.
How does the enable (EN) pin function on MAX336EAI?
The EN pin is an active-high digital input that globally enables or disables all 16 analog switches. When EN = 0V (logic low), all switches enter high-impedance off-state regardless of address inputs. When EN = 2.4V (logic high), the device decodes A0–A3 to connect the selected NOx channel to COM. EN is TTL/CMOS-compatible and operates across the full –40°C to +85°C range and ±4.5V to ±18V supply span.
