Product details
Overview
MAX4612EPD from Maxim Integrated is a quad, low-voltage, SPST CMOS analog switch with two normally open (NO) and two normally closed (NC) channels. It operates from a single +2V to +12V supply, delivers ≤100Ω on-resistance at +5V, matches channel RON within 4Ω max, and supports rail-to-rail analog signal handling (GND to V+). It is used in battery-powered audio routing and low-voltage data-acquisition systems where leakage-critical switching is required.
For engineers reviewing the MAX4612EPD datasheet, MAX4612EPD pinout, MAX4612EPD application, or MAX4612EPD equivalent, key selection criteria include its dual NO/NC topology, guaranteed on-resistance flatness (≤18Ω), sub-2nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and operation across -40°C to +85°C industrial temperature range.
Technical Context
The MAX4612EPD implements four independent CMOS transmission gates controlled by digital inputs IN1–IN4, with dedicated NO1/NO2 and NC3/NC4 terminals. Its switch architecture ensures matched conduction characteristics and minimal charge injection (1–5pC), enabling precision sample-and-hold and low-distortion signal routing.
It features internal ESD protection (>2kV per Method 3015.7), rail-to-rail analog voltage support (0V to V+), and logic thresholds fixed at +0.8V (low) and +2.4V (high) for reliable +5V TTL/CMOS interfacing without level shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 12V systems without auxiliary rails |
| On-Resistance (RON) | ≤100Ω max at +5V - ensures minimal signal attenuation and voltage drop in low-level analog paths |
| RON Match | ≤4Ω max between channels - critical for matched gain/attenuation in differential or multi-channel sensing |
| Off-Leakage Current | <2nA at +85°C - preserves accuracy in high-impedance sample-and-hold and sensor front-ends |
| Signal Range | GND to V+ - supports full-rail analog signals without clamping or distortion |
| Logic Thresholds | +0.8V (low), +2.4V (high) - guarantees interoperability with standard 5V TTL and CMOS controllers |
| Bandwidth | 300MHz - suitable for audio, video, and medium-speed data-switching applications |
Pinout & Package
MAX4612EPD is supplied in a 14-pin plastic DIP package (PDIP), with exposed pad not applicable (non-QFN variant). Pin assignments are standardized across the MAX461x family for PCB layout reuse.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | NO1, NO3 | Normally open analog outputs - connect only when corresponding IN1/IN3 is HIGH |
| 3, 11 | NC2, NC4 | Normally closed analog outputs - disconnect only when corresponding IN2/IN4 is HIGH |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - serve as bidirectional signal ports for all four switches |
| 13, 5, 6, 12 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible; drive switch state (NO/NC) directly |
| 7 | GND | Digital/analog reference ground - must be tied to system ground plane for noise immunity |
| 14 | V+ | Positive supply - powers analog and digital sections; bypass with 0.1µF capacitor near pin |
Key Features
| Feature | Design Value |
|---|---|
| Dual NO/NC configuration | Two independent NO and two NC switches enable flexible signal path selection (e.g., default-closed backup + active-high primary) |
| Guaranteed RON flatness | ≤18Ω over full signal range - maintains consistent gain/loss across input voltage swing in precision instrumentation |
| Rail-to-rail signal handling | Supports analog signals from GND to V+ - eliminates need for external level-shifting in single-supply systems |
| ESD robustness | >2kV per Method 3015.7 - enhances reliability in handling-sensitive industrial and portable equipment |
| Low THD+N | 0.009% at 20Hz–20kHz - preserves fidelity in audio routing and measurement-grade signal chains |
Applications
| Audio Signal Routing | Low-Voltage Data Acquisition |
|---|---|

IC Role / Device Role / Timing Role: Fail-safe analog switch blocking fault currents and preventing backfeeding into powered-down logic. Use Value: Dual NO/NC topology allows one path to remain closed (NC) for default connectivity while NO path enables active isolation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612EUD+ | 14-pin TSSOP package; same electrical specs and -40°C to +85°C rating | Higher board density; requires reflow-compatible layout | Select for space-constrained PCBs where surface-mount assembly is available |
| ADG1412BRUZ | Quad SPST, ±15V dual-supply capable; higher RON (1.8Ω typical), but wider voltage range | Supports bipolar signal routing; unsuitable for single-supply ≤2.7V systems | Choose when ±5V/±12V operation or lower on-resistance at high VSUPPLY is required |
Compared with MAX4612EPD, MAX4612EUD+ offers identical functionality in a smaller TSSOP package but demands SMT capability, while ADG1412BRUZ provides superior RON and bipolar support at the cost of higher supply complexity and incompatibility with sub-3V operation.

FAQ
What is the maximum supply voltage for MAX4612EPD?
The absolute maximum supply voltage (V+) for MAX4612EPD is +13V referenced to GND. Operation above +12V is possible but requires careful bypassing (≥0.1µF ceramic capacitor close to V+ and GND pins) and attention to tolerance-induced overshoot. The recommended operating range remains +2V to +12V per the datasheet's electrical characteristics tables.
Does MAX4612EPD support rail-to-rail analog signals?
Yes, MAX4612EPD supports analog signals from GND to V+ across all COM, NO, and NC terminals. This rail-to-rail capability is explicitly guaranteed in the datasheet's "Analog Signal Range" parameter (0V to V+) and enables direct interfacing with single-supply op amps and ADCs without level-shifting circuitry.
How does the dual NO/NC configuration of MAX4612EPD benefit system design?
The MAX4612EPD integrates two normally open (NO) and two normally closed (NC) switches, allowing fail-safe or default-path configurations - for example, an NC switch can maintain signal continuity during MCU reset or power loss, while an NO switch enables active control. This eliminates external diodes or relays in redundancy-critical signal routing.
What is the off-leakage current specification for MAX4612EPD at elevated temperature?
MAX4612EPD guarantees NO/NC off-leakage current of ≤2nA at TA = +85°C, and ≤1nA at TA = +25°C. This is confirmed in the "ELECTRICAL CHARACTERISTICS-Single +5V Supply" table and validated per Note 6 (100% tested at max-rated hot temperature).
Is MAX4612EPD pin-compatible with industry-standard analog switches?
Yes, MAX4612EPD is pin-compatible with the industry-standard 74HC4066 and MAX4066 in its 14-pin PDIP package. Pin functions (COM, NO/NC, IN, V+, GND) align directly, enabling drop-in replacement where matching electrical specs (e.g., supply range, RON, leakage) meet system requirements.
