Product details
Overview
MAX4712CPE+ from Maxim Integrated is a fault-protected, quad SPST analog switch with normally open (NO) configuration, designed for signal routing in low-voltage systems. It delivers 25Ω max on-resistance at +25°C, <125ns turn-on time, and ±12V fault protection on NO/NC pins with power off - enabling robust operation in battery-powered test equipment and industrial control interfaces.
For engineers reviewing the MAX4712CPE+ datasheet, MAX4712CPE+ pinout, MAX4712CPE+ application, or MAX4712CPE+ equivalent, key selection criteria include fault-protection voltage margins under single/dual supply, on-resistance matching across channels, rail-to-rail signal handling capability, and compatibility with TTL/CMOS logic levels across +2.7V to +11V operation.
Technical Context
The MAX4712CPE+ implements dual-FET (N+P channel) parallel switching architecture per channel to achieve low RON and flat on-resistance vs. signal voltage. Its integrated fault-sensing comparators monitor NO/NC pins against V+ and V− rails; exceeding either by ~150mV triggers automatic shutdown and output clamping to the appropriate supply rail.
Fault response includes sub-200ns turn-on delay during overvoltage events and 700ns recovery time post-fault, with clamp FETs capable of sourcing/sinking up to ±15mA. The COM pins lack fault protection and rely on internal ESD diodes - requiring external voltage limiting if driven beyond supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 25Ω max at +25°C, +4.5V/−4.5V supplies - ensures minimal signal attenuation in precision analog paths |
| RON match | 1Ω max between channels - critical for matched gain/phase in multi-channel signal routing |
| Turn-on time (tON) | <125ns - supports high-speed multiplexing in data-acquisition and communication systems |
| Fault protection range | ±12V on NO/NC with power off - enables safe hot-plug and transient immunity in field-deployed equipment |
| Supply range | +2.7V to +11V single or ±2.7V to ±5.5V dual - supports wide input voltage flexibility in portable and industrial designs |
| Logic compatibility | TTL/CMOS thresholds (VIH = 2.4V, VIL = 0.8V at +5V) - simplifies interface with microcontrollers and FPGAs |
| Off-isolation | −59dB at 1MHz - suppresses crosstalk between inactive channels in dense signal routing |
Pinout & Package
MAX4712CPE+ uses a 16-pin Plastic DIP package (0.300" width), rated for 0°C to +70°C operation. Pin assignments follow industry-standard layout compatible with MAX392.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Fault-protected logic inputs; accept VIH ≥ 2.4V / VIL ≤ 0.8V with ±12V tolerance relative to V− |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - not fault-protected; must remain within V− to V+ range |
| 3, 6, 11, 14 | NO1–NO4 | Fault-protected normally open analog inputs - clamp to V+ or V− during overvoltage faults |
| 4 | V− | Negative supply input; connect to GND for single-supply operation |
| 5 | GND | Ground reference for logic and analog sections |
| 12 | N.C. | No internal connection - leave unconnected |
| 13 | V+ | Positive supply input; supports up to +11V or ±5.5V dual rail |
Key Features
| Feature | Design Value |
|---|---|
| Fault-protected NO inputs | Withstands ±12V transients on NO pins even with power removed - eliminates need for external TVS in many front-end designs |
| Rail-to-rail signal handling | Passes signals from V− to V+ without distortion - essential for full-scale sensor and DAC outputs |
| Output clamping during fault | COM pin clamped to same-polarity supply rail (V+ or V−) - prevents downstream IC damage |
| Pin-compatible replacement | Direct drop-in for MAX392 in existing layouts - reduces redesign effort while adding fault resilience |
| All-switches-off with power loss | Guaranteed high-impedance state when V+ or V− is absent - prevents backfeeding or signal leakage |
Applications
| Battery-Operated Test Equipment | Redundant Signal Routing |
|---|---|
Use Scenario: Portable multimeter or handheld signal analyzer switching between multiple sensor inputs under variable battery voltage (2.7V–5.5V). IC Role / Device Role / Timing Role: Quad SPST NO switch isolating analog front-end paths while maintaining rail-to-rail signal integrity. Use Value: Fault protection prevents latch-up during probe misconnection; low RON preserves measurement accuracy across battery discharge cycle. | Use Scenario: Avionics system with dual independent sensor feeds routed to a primary controller, where failure of one path must not affect the other. IC Role / Device Role / Timing Role: Isolation switch enabling automatic failover via logic-controlled channel enable/disable. Use Value: ±12V fault margin protects against induced transients in aircraft wiring harnesses; break-before-make timing avoids short-circuit during switchover. |
| Industrial Process Control I/O | Communication System Signal Multiplexing |
Use Scenario: PLC analog input module conditioning 4–20mA loop signals with potential ground-loop-induced overvoltages. IC Role / Device Role / Timing Role: Front-end protection and routing element before ADC stage. Use Value: Clamp current limit (±15mA) safely shunts fault energy; low leakage (<10nA) avoids offset errors in high-impedance sensing circuits. | Use Scenario: Base station RF subsystem selecting between multiple IF signal paths using digital control. IC Role / Device Role / Timing Role: High-isolation analog switch enabling clean signal path selection without cross-coupling. Use Value: −59dB off-isolation at 1MHz suppresses adjacent-channel interference; fast tOFF (<80ns) minimizes switching glitches in time-division systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX392CPE+ | No fault protection; 35Ω max RON; identical pinout and logic interface | Suitable only in benign environments with controlled signal ranges and no risk of overvoltage | Select when cost sensitivity outweighs fault resilience requirements and system-level protection is already implemented externally |
| ADG1412BRUZ | 4-channel SPST, ±15V supply rating, 1.8Ω RON, but no built-in fault clamping | Higher performance for precision instrumentation, but requires external overvoltage protection circuitry | Choose when ultra-low on-resistance and wider supply range are prioritized, and board space allows discrete protection components |
Compared with MAX392CPE+, the MAX4712CPE+ adds ±12V fault tolerance without changing PCB layout; versus ADG1412BRUZ, it trades lower RON for integrated fault response - reducing BOM count and improving reliability in harsh electrical environments.

FAQ
What is the maximum fault voltage the MAX4712CPE+ can withstand on its NO pins with power removed?
The MAX4712CPE+ sustains ±12V on NO pins with power off, as confirmed in Absolute Maximum Ratings and Electrical Characteristics tables. This applies regardless of supply voltage level, including V+ = V− = 0V. The device enters high-impedance state, preventing current flow into internal circuitry - making it ideal for hot-swap and maintenance scenarios where inputs may be exposed before power-up.
Does the MAX4712CPE+ support single-supply operation, and what is the minimum operating voltage?
Yes, the MAX4712CPE+ operates from a single +2.7V to +11V supply with V− tied to GND. At +2.7V, logic thresholds shift to VIH = 2.0V and VIL = 0.6V to maintain CMOS compatibility. On-resistance rises to 100Ω max at +2.7V/25°C, but remains monotonic and predictable - enabling use in ultra-low-power sensor nodes and energy-harvesting systems.
How does fault protection work on the COM pins of the MAX4712CPE+?
The COM pins of the MAX4712CPE+ are not fault-protected. They connect directly to internal ESD diodes referenced to V+ and V−. If a COM pin voltage exceeds V+ or falls below V− by more than ~0.7V, the corresponding diode conducts - potentially damaging the device if current exceeds ±40mA. Therefore, external clamping or limiting is required when COM signals may exceed supply rails, unlike the self-protecting NO pins.
Is the MAX4712CPE+ pin-compatible with standard industry analog switches?
Yes, the MAX4712CPE+ features identical pinout to the MAX392 and other industry-standard quad SPST NO switches in 16-pin DIP, SO, and TSSOP packages. This enables direct replacement in legacy designs. However, only NO/NC pins inherit fault protection - COM and logic pins retain standard behavior, so existing layouts require no modification but gain enhanced robustness without functional change.
What is the typical on-resistance flatness across signal voltage for the MAX4712CPE+?
The MAX4712CPE+ guarantees on-resistance flatness (RFLAT) of 5Ω max over the full signal range (V− to V+) at +25°C under ±4.5V supplies. This means RON varies by no more than ±2.5Ω across the entire analog input span - preserving linearity in audio, sensor, and DAC output buffering applications where harmonic distortion must be minimized.
