Product details
Overview
MAX4515EPA from Maxim Integrated is a normally closed (NC), single-pole/single-throw (SPST), CMOS analog switch optimized for low-voltage, rail-to-rail signal routing. It operates from +2V to +12V single supply, delivers 10Ω on-resistance at +12V, guarantees ≤20nA off-leakage at +85°C, and supports TTL/CMOS logic compatibility with +5V supply - ideal for battery-powered audio/video switching and low-voltage data acquisition.
For engineers reviewing the MAX4515EPA datasheet, MAX4515EPA pinout, MAX4515EPA application, or MAX4515EPA equivalent, key selection criteria include its NC configuration, -40°C to +85°C extended temperature range, SOT23-5 package footprint, and verified performance in PCMCIA card signal path control and cellular phone audio routing.
Technical Context
The MAX4515EPA implements a complementary CMOS transmission gate architecture with internal level translators enabling full rail-to-rail analog signal handling across its COM–NC path. Its digital input accepts 0.8V to 2.4V logic thresholds at +5V supply, ensuring direct interface with standard microcontroller GPIOs without external level shifting.
ESD protection diodes are integrated between each analog terminal (COM, NC) and both V+ and GND, defining absolute maximum analog voltage limits as -0.3V to (V+ + 0.3V). All leakage currents - including 20nA max NC off-leakage at +85°C - originate from these reverse-biased diodes, not inter-terminal conduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Normally closed (NC) SPST analog switch - conducts when IN = LOW, blocks when IN = HIGH. |
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 12V systems without auxiliary rails. |
| On-Resistance | 10Ω max at +12V supply - ensures minimal signal attenuation and distortion in precision analog paths. |
| Off-Leakage Current | 20nA max at +85°C - preserves signal integrity in high-impedance sensor interfaces and battery-critical standby modes. |
| Switching Speed | tON = 150ns, tOFF = 100ns at +5V - supports fast multiplexing in data-acquisition and communications circuits. |
| Charge Injection | 10pC max - limits voltage glitch on sampled-hold nodes and prevents error accumulation in ADC front-ends. |
| Logic Compatibility | 0.8V to 2.4V input thresholds at +5V supply - directly interfaces with 5V TTL and CMOS outputs without level shifters. |
Pinout & Package
MAX4515EPA is housed in an 8-pin plastic DIP package (0.300" wide), compatible with through-hole prototyping and industrial PCB assembly. Pin 1 is COM (common), Pin 2 is NC (normally closed), Pin 3 is N.C. (not internally connected), Pin 4 is V+, Pin 5 is GND, Pin 6 is IN (digital control input), Pin 7 is N.C., Pin 8 is N.C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (COM) | Analog common terminal | Shared signal path node - connects to either NC or external circuit; bidirectional signal flow supported. |
| 2 (NC) | Normally closed analog terminal | Conducts to COM when IN = LOW; open-circuit when IN = HIGH - defines default signal path state. |
| 3, 7, 8 | No internal connection | Unbonded pins - must be left floating or grounded per layout best practices; no electrical function. |
| 4 (V+) | Positive supply rail | Powers analog switch core and digital interface; sets upper analog voltage limit (V+ ±0.3V). |
| 5 (GND) | Ground reference | Reference for all analog signals and digital inputs; establishes lower analog voltage limit (-0.3V). |
| 6 (IN) | Digital control input | Active-low logic input - LOW enables NC–COM conduction; HIGH disables path with break-before-make timing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports VCOM, VNC from GND to V+ - eliminates clipping in audio, sensor, and video signal chains. |
| Guaranteed low on-resistance flatness | ΔRON ≤ 3Ω over full signal range at +5V - maintains consistent gain and linearity across varying input voltages. |
| Break-before-make switching | tON > tOFF at +5V - prevents momentary shorting during state transitions in multi-channel routing applications. |
| Low charge injection (10pC) | Minimizes voltage step on high-impedance nodes - critical for precision sample-and-hold and switched-capacitor circuits. |
| ESD robustness | >2000V per Method 3015.7 - enhances reliability in handheld and field-deployable equipment assembly and operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4515ESA | Same electrical specs, but in 8-pin SO package - 5.0mm × 4.4mm body, surface-mount only. | Requires reflow-compatible PCB layout; unsuitable for through-hole prototyping or legacy DIP sockets. | Select MAX4515ESA for automated SMT production where board space and thermal performance outweigh manual assembly needs. |
| ADG1419BRMZ | NC SPST switch with 1.5Ω on-resistance at +15V, but requires dual ±15V supplies or +30V single supply - not pin-compatible. | Higher performance in precision test equipment, but incompatible with +2V to +12V single-supply systems like MAX4515EPA. | Choose ADG1419BRMZ only when ultra-low on-resistance justifies redesigning power delivery and layout for higher voltage operation. |
Compared with MAX4515ESA and ADG1419BRMZ, the MAX4515EPA uniquely balances through-hole manufacturability, extended temperature support (-40°C to +85°C), and guaranteed 10Ω on-resistance within a +2V to +12V single-supply envelope - making it optimal for cost-sensitive, field-deployable, and mixed-technology designs.

FAQ
What is the operating temperature range of the MAX4515EPA?
The MAX4515EPA is rated for operation from -40°C to +85°C. This extended temperature range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet, where "E" grade parts are explicitly defined as -40°C to +85°C. The MAX4515EPA's leakage current, on-resistance, and switching speed specifications are guaranteed across this full range, making it suitable for industrial and automotive cabin environments.
Is the MAX4515EPA pin-compatible with the MAX4514EPA?
Yes, the MAX4515EPA is pin-compatible with the MAX4514EPA in the same package variant - both use identical 8-pin DIP footprints and share identical pin functions (COM, NC/NO, IN, V+, GND, and N.C. pins). The only functional difference is the default switch state: MAX4515EPA is normally closed (NC), while MAX4514EPA is normally open (NO). No PCB layout changes are required when substituting between them for evaluation or design flexibility.
Can the MAX4515EPA operate from a +3.3V supply?
Yes, the MAX4515EPA supports +2V to +12V single-supply operation, and its electrical characteristics are validated down to +3V in the datasheet's +3V Supply section. At +3.3V, on-resistance increases to ~50Ω (max), off-leakage remains ≤20nA at +85°C, and logic thresholds adapt accordingly - confirming reliable functionality in modern 3.3V embedded systems without level translation.
What is the maximum analog signal voltage the MAX4515EPA can handle?
The MAX4515EPA supports rail-to-rail analog signals from GND to V+. Its Absolute Maximum Ratings specify that any analog terminal (COM or NC) may swing from -0.3V to (V+ + 0.3V), but functional operation is guaranteed only between GND and V+. For example, with V+ = +5V, the valid analog signal range is 0V to +5V - exceeding this risks ESD diode conduction and potential damage.
Does the MAX4515EPA require external pull-up or pull-down resistors on its IN pin?
No, the MAX4515EPA does not require external biasing on the IN pin. Its digital input has guaranteed TTL/CMOS-compatible thresholds (0.8V to 2.4V at +5V supply), and internal circuitry provides sufficient noise immunity and logic-level recognition. Driving IN directly from a microcontroller GPIO or FPGA output - whether actively high/low or open-drain with appropriate pull-up - is fully supported per the Applications Information section.
