Product details
Overview
MAX354CPE from Maxim Integrated is a fault-protected single 8-channel analog multiplexer IC designed for high-reliability signal routing in industrial and avionics systems. It operates from ±4.5V to ±18V dual supplies (or +4.5V to +36V single supply), features 350Ω max on-resistance, <0.5nA input leakage at +25°C, and guarantees break-before-make switching. It protects downstream circuitry against continuous ±40V overvoltage faults-even with power supplies off.
For engineers reviewing the MAX354CPE datasheet, MAX354CPE pinout, MAX354CPE application, or MAX354CPE equivalent, this page delivers verified electrical parameters, fault-protection behavior under rail-exceeding conditions, leakage vs. temperature curves, charge injection data at ±15V/±10V/±5V, and precise truth-table–driven channel selection logic-critical for data-acquisition and redundant-system design.
Technical Context
The MAX354CPE implements a series N-channel/P-channel/N-channel FET structure that actively clamps output voltage to ~1.5V below V+ and ~3V above V− during overvoltage events, limiting fault current to sub-microamp levels. Its digital inputs use fixed 0.8V/2.4V TTL-compatible thresholds referenced to GND, independent of supply voltage variation.
When analog signals exceed ±13.5V (with ±15V supplies), internal gate structures increase on-resistance to infinity, blocking conduction while maintaining polarity integrity and eliminating glitches. Charge injection is characterized across supply voltages (±5V/±10V/±15V) and analog input levels, with typical values of 15–180pC depending on operating point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 350Ω max - ensures low signal attenuation and minimal gain error in precision measurement paths |
| Fault Protection Range | ±40V continuous - protects connected ADCs, amplifiers, or microcontrollers even with V+/V− unpowered |
| Input Leakage Current | 0.5nA max at +25°C - preserves high-impedance sensor node accuracy without external guarding |
| Supply Voltage Range | ±4.5V to ±18V dual or +4.5V to +36V single - supports wide industrial and avionics rail configurations |
| Break-Before-Make Interval | 100ns min - prevents momentary shorting between channels during address transitions |
| Logic Thresholds | 0.8V low / 2.4V high - enables direct interface with TTL and CMOS without pull-ups or level shifters |
| Charge Injection | 15pC to 180pC - determines settling time penalty in S/H circuits; load capacitance directly scales induced voltage step |
Pinout & Package
MAX354CPE is housed in a 16-pin plastic DIP package (0.300" wide), rated for 0°C to +70°C operation. Pin functions are electrically symmetric for analog I/O, supporting bidirectional signal flow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 | Binary address inputs selecting one of eight NOx channels to connect to COM |
| 2 | EN | Active-high enable controlling all switch conduction; disables all channels when low |
| 3 | V− | Negative supply rail; tied to GND for single-supply operation |
| 4–7 | NO1–NO4 | Analog input/output terminals for channels 1–4 |
| 8 | COM | Common analog terminal - bidirectional connection point for selected channel |
| 9–12 | NO5–NO8 | Analog input/output terminals for channels 5–8 |
| 13 | GND | Ground reference for logic thresholds and internal protection circuitry |
| 14 | V+ | Positive supply rail - powers internal FET gates and defines upper fault clamp level |
| 15 | A2 | Third address bit (not used in MAX354; reserved for family compatibility) |
Key Features
| Feature | Design Value |
|---|---|
| Fault-clamped output | Clamps at ~1.5V below V+ and ~3V above V− - prevents damage to downstream op-amps or ADC inputs |
| No power-up sequencing | Safe operation regardless of V+/V− ramp order - eliminates need for external supply supervisors |
| All switches off with supplies off | Zero conduction path when V+/V− = 0V - avoids back-driving of unpowered systems |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds with <1µA input current - interfaces directly with microcontroller GPIOs |
| Demultiplexing support | Full bidirectional analog path - enables reverse signal routing without performance degradation |
Applications
| Industrial Process Control | Data-Acquisition Systems |

IC Role / Device Role / Timing Role: Fault-isolated channel selector ensuring no fault propagation between redundant branches. Use Value: Output clamping and sub-µA fault current prevent single-point failure from disabling both monitoring paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG508F | Pin-compatible but lacks ±40V fault protection; max overvoltage = ±25V with supplies on, ±20V with supplies off | Suitable only in benign environments where wiring faults are mitigated externally | Select ADG508F only if system-level protection (TVS, series resistors) already limits fault energy below MAX354CPE's native capability |
| MAX358 | Same fault-protection architecture but octal SPST (non-multiplexed); no address decoding or EN pin | Used when independent channel control is required instead of sequential scanning | Choose MAX358 when individual channel enable/disable per signal path is needed, not shared COM routing |
Compared with ADG508F and MAX358, the MAX354CPE uniquely combines 8:1 multiplexing, integrated ±40V fault tolerance, and TTL/CMOS-compatible logic in a single 16-pin DIP-enabling simplified BOMs and reduced PCB area in safety-critical analog signal chains.

FAQ
What is the maximum continuous overvoltage the MAX354CPE can withstand with power supplies off?
The MAX354CPE withstands ±40V continuous overvoltage on any analog input or output pin-even when V+ and V− are disconnected or at 0V. This is achieved via its series FET protection structure, which blocks conduction while limiting leakage to sub-nanoamp levels. The MAX354CPE datasheet specifies this rating in Absolute Maximum Ratings and confirms it in Figure 8 through Figure 11 fault-condition analysis.
Does the MAX354CPE support demultiplexing operation, and how does fault protection behave in that mode?
Yes, the MAX354CPE supports full bidirectional operation and functions as a demultiplexer when the COM pin is driven and NOx pins serve as outputs. Fault protection remains fully active: overvoltage applied to any NOx pin while COM is active triggers the same clamping and current-limiting behavior as in multiplexing mode. This capability is explicitly documented in the "Operation as a Demultiplexer" section of the MAX354CPE datasheet.
What is the guaranteed on-resistance matching between channels for the MAX354CPE?
The MAX354CPE guarantees ∆RON (RONMAX − RONMIN) ≤ 15Ω across all eight channels at TA = TMIN to TMAX, with typical matching tighter than 7Ω. This parameter ensures consistent gain and settling behavior when switching between channels in precision measurement applications. The value is specified in the Electrical Characteristics table under "On-Resistance Matching Between Channels."
Can the MAX354CPE operate from an asymmetrical supply, such as +15V and −5V?
Yes, the MAX354CPE supports asymmetrical supplies including +15V/−5V. Its analog performance-including on-resistance, leakage, and fault-clamp levels-depends on the total V+−V− differential. With +15V/−5V, the output swing is limited to approximately +13.5V (1.5V below V+) and −2V (3V above V−). Digital thresholds remain referenced to GND and retain TTL compatibility, as confirmed in the "Operation with Supply Voltages Other than ±15V" section of the MAX354CPE datasheet.
Is the MAX354CPE pin-compatible with the MAX354EPE or MAX354MJE variants?
Yes, the MAX354CPE shares identical pinout and footprint with MAX354EPE (−40°C to +85°C) and MAX354MJE (−55°C to +125°C) - all use the 16-pin plastic DIP package. The only differences are temperature rating and screening level; electrical specifications at respective temperature ranges are fully compatible. This allows drop-in replacement for extended temperature upgrades without PCB redesign.
