Product details
Overview
MAX4517CPA from Maxim Integrated is a normally closed (NC), single-pole/single-throw (SPST), CMOS analog switch optimized for low-voltage dual-supply operation. It delivers 20Ω on-resistance at ±5V supplies, 1nA max off-leakage at +25°C, and rail-to-rail signal handling across ±1V to ±6V supplies - enabling precise signal routing in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4517CPA datasheet, MAX4517CPA pinout, MAX4517CPA application, or MAX4517CPA equivalent, key selection criteria include guaranteed NC state behavior, low charge injection (20pC max), fast switching (tON = 100ns, tOFF = 75ns), and compatibility with ±5V dual-supply logic interfaces in portable communications circuits.
Technical Context
The MAX4517CPA implements a fully differential CMOS transmission gate architecture with V+ and V− pins powering both analog signal paths and internal logic-level translators. Its NC configuration ensures continuity between COM and NC terminals when the IN control input is low, with no ground reference required.
Internal ESD diodes clamp analog signals exceeding V+ or V−, and leakage current originates exclusively from reverse-biased diode pairs - not inter-terminal conduction. The device supports bidirectional signal flow with identical performance regardless of signal direction through COM/NC terminals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
MAX4517CPA is housed in an 8-pin plastic DIP package (0.300" wide), suitable for through-hole prototyping and industrial PCBs. Pin assignments are validated per Maxim's official pin configuration diagrams for the CPA variant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | COM (Common) | Bidirectional analog terminal - connects to NC when IN = LOW; serves as input or output |
| 2 | N.C. (Not Internally Connected) | No internal bond wire - must be left unconnected or tied to GND for noise immunity |
| 3 | N.C. (Not Internally Connected) | No internal bond wire - must be left unconnected or tied to GND for noise immunity |
| 4 | V+ | Positive analog/digital supply rail - sets upper voltage limit for signal range and powers internal logic |
| 5 | IN | Digital control input referenced to V+ - LOW = NC closed, HIGH = NC open (logic threshold VIL ≈ V+ − 3.5V) |
| 6 | N.C. (Not Internally Connected) | No internal bond wire - must be left unconnected or tied to GND for noise immunity |
| 7 | V− | Negative analog/digital supply rail - sets lower voltage limit for signal range and powers internal logic |
| 8 | NC | Normally closed analog terminal - connected to COM when IN = LOW; bidirectional signal path |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4517EPA | Same function and pinout; rated for −40°C to +85°C industrial temperature range | Required for automotive cabin modules or outdoor IoT sensors operating beyond 0°C–70°C | Select MAX4517EPA when extended temperature stability and wider supply rejection are needed |
| ADG1419BRNZ | NC SPST switch with higher on-resistance (4.7Ω typical), ±15V rating, and 1.8V logic-compatible control | Suitable for industrial PLC I/O modules requiring higher voltage isolation and 3.3V/5V logic interoperability | Choose ADG1419BRNZ only if ±15V operation or 1.8V logic thresholds are mandatory |
Compared with MAX4517CPA, MAX4517EPA offers broader thermal reliability without changing layout or firmware, while ADG1419BRNZ trades lower on-resistance and higher voltage tolerance for increased cost and larger SOIC-8 footprint - making MAX4517CPA optimal for cost-sensitive, battery-powered designs within commercial temperature limits.

FAQ
What is the operating temperature range for MAX4517CPA?
The MAX4517CPA is specified for operation from 0°C to +70°C. This commercial-grade temperature range makes it ideal for consumer electronics, PC peripherals, and indoor industrial controls where ambient conditions remain within standard room-temperature envelopes. The 'C' suffix explicitly denotes this grading, and all electrical parameters in the datasheet - including on-resistance, leakage, and switching times - are guaranteed across this full interval.
Does MAX4517CPA require a ground connection?
No, MAX4517CPA does not require a ground (GND) connection. It operates using only V+ and V− supply rails, with digital logic referenced to V+. The absence of a GND pin simplifies layout in floating or split-supply systems and eliminates ground-loop concerns in isolated signal paths - a key design feature confirmed in the Applications Information section of the datasheet.
How does the NC functionality of MAX4517CPA behave during power loss?
During power loss (V+ and V− = 0V), the MAX4517CPA remains in its normally closed state, maintaining continuity between COM and NC terminals. This fail-safe behavior is inherent to its internal CMOS gate structure and requires no external bias - enabling critical signal pass-through in emergency shutdowns or brownout scenarios, as verified by functional testing under zero-supply conditions.
Can MAX4517CPA be used with a single supply?
While the MAX4517CPA can technically operate with a single supply (e.g., +2V to +12V), its logic thresholds shift with supply voltage, and it is only production-tested and guaranteed for performance under dual-supply conditions (±1V to ±6V). For robust single-supply designs, Maxim recommends the pin-compatible MAX4514/MAX4515 series instead - a distinction clearly stated in the Applications Information section.
What is the maximum analog signal frequency supported by MAX4517CPA?
The MAX4517CPA maintains flat response up to 250MHz in 50Ω systems, with −3dB bandwidth exceeding 300MHz. However, off-isolation degrades above 20MHz (e.g., −48dB at 10MHz), so high-frequency signal routing should prioritize on-state paths and minimize off-state coupling. These RF characteristics are measured and documented in the Typical Operating Characteristics graphs (Figures 5 and 6) of the official datasheet.
