Product details
Overview
MAX4612EUD+ from Maxim Integrated is a quad, low-voltage, SPST analog switch with two normally open (NO) and two normally closed (NC) channels, operating from +2V to +12V supply. It delivers 100Ω max on-resistance at +5V, 4Ω max channel-to-channel match, rail-to-rail signal handling (GND to V+), and <2nA off-leakage at +85°C - enabling precision signal routing in battery-powered instrumentation and audio multiplexing.
For engineers reviewing the MAX4612EUD+ datasheet, MAX4612EUD+ pinout, MAX4612EUD+ application, or MAX4612EUD+ equivalent, key selection criteria include verified on-resistance flatness (18Ω max), TTL/CMOS logic compatibility at +5V, ESD robustness (>2kV per Method 3015.7), and guaranteed -40°C to +85°C operation in 14-pin TSSOP packaging.
Technical Context
The MAX4612EUD+ implements four independent CMOS transmission gates controlled by digital inputs IN1–IN4, each driving one NO or NC switch. Its architecture ensures matched RON across channels and minimal variation over the full analog signal range (0V to V+).
Logic thresholds are fixed at +0.8V (low) and +2.4V (high) for +5V operation, eliminating level-shifting needs. All switches support bidirectional analog signals, with COM pins serving as common terminals and NO/NC pins as complementary switch outputs - no internal pull-ups/downs or latching logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply - supports direct integration into 3.3V, 5V, and 9V systems without external regulators. |
| On-Resistance (RON) | 100Ω max at +5V - ensures minimal signal attenuation and voltage drop in low-current analog paths. |
| RON Match | 4Ω max between channels - critical for gain-matching in multi-channel data acquisition front-ends. |
| Off-Leakage Current | <2nA at +85°C - preserves accuracy in high-impedance sample-and-hold and sensor interface circuits. |
| Analog Signal Range | GND to V+ - enables true rail-to-rail switching of DC and AC signals without clipping. |
| Logic Compatibility | TTL/CMOS thresholds (+0.8V / +2.4V) at +5V - interfaces directly with microcontrollers and FPGAs without glue logic. |
| ESD Protection | >2kV per Method 3015.7 - withstands handling and board-level electrostatic discharge in industrial environments. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612ESD+ | Same electrical specs, but in 14-pin narrow SO package - larger footprint, lower thermal resistance than TSSOP. | Preferred where manual soldering or board-level rework is required; less suitable for high-density layouts. | Select MAX4612ESD+ when SO package mechanical robustness or thermal margin outweighs space constraints. |
| ADG1412BRUZ | Quad SPST, 1.5Ω RON typical at +5V, but 16-pin TSSOP, higher supply current (20µA vs. 1µA), and no automotive temp grade. | Used in high-precision lab equipment where ultra-low RON dominates over leakage and temperature range. | Choose ADG1412BRUZ only if sub-2Ω RON is mandatory and -40°C to +85°C operation is not required. |
Compared with MAX4612EUD+, MAX4612ESD+ offers identical functionality in a more serviceable package, while ADG1412BRUZ trades leakage performance and temperature range for lower on-resistance - making MAX4612EUD+ optimal for battery-powered and wide-temperature industrial designs.

FAQ
What is the maximum supply voltage for MAX4612EUD+?
The absolute maximum supply voltage for MAX4612EUD+ is +13V referenced to GND. Continuous operation is specified up to +12V. Exceeding +13V risks permanent damage. When operating near the limit, a minimum 0.1µF ceramic bypass capacitor must be placed close to the V+ pin. The MAX4612EUD+ datasheet specifies derating curves for power dissipation above +70°C ambient.
Does MAX4612EUD+ support bidirectional analog signal routing?
Yes, MAX4612EUD+ supports fully bidirectional analog signal routing on all COM–NO and COM–NC paths. There is no intrinsic directionality - voltage or current can flow equally from COM to NO/NC or vice versa, provided signals remain within the GND-to-V+ range. This enables use in both signal multiplexing and demultiplexing configurations without polarity constraints.
How does the dual NO/NC configuration of MAX4612EUD+ differ from MAX4610EUD+ and MAX4611EUD+?
MAX4612EUD+ integrates two normally open (NO) and two normally closed (NC) switches in one package. In contrast, MAX4610EUD+ contains four NO switches only, while MAX4611EUD+ contains four NC switches only. This hybrid configuration allows MAX4612EUD+ to implement break-before-make or make-before-break switching topologies without external logic, unlike the single-mode variants which require additional components for such functionality.
Is MAX4612EUD+ pin-compatible with industry-standard analog switches?
MAX4612EUD+ is pin-compatible with the industry-standard 74HC4066 and MAX4066 in its 14-pin TSSOP footprint. Pin assignments for V+, GND, COMx, INx, NOx, and NCx align directly - enabling drop-in replacement in existing designs. However, note that MAX4612EUD+ offers superior on-resistance matching (4Ω max vs. ~10Ω typical for 74HC4066) and guaranteed rail-to-rail operation down to +2V supply.
What is the leakage current specification for MAX4612EUD+ at elevated temperatures?
MAX4612EUD+ guarantees NO/NC off-leakage current of ≤2nA at TA = +85°C and ≤1nA at TA = +25°C. COM off-leakage is similarly rated at ≤2nA at +85°C. These values are 100% tested at hot temperature and correlated at room temperature per the datasheet. Leakage remains stable across the full -40°C to +85°C operating range, supporting reliable performance in thermally demanding environments.
