Product details
Overview
MAX4612CSD+ from Maxim Integrated is a quad, low-voltage, SPST CMOS analog switch with two normally open (NO) and two normally closed (NC) channels, 100Ω max on-resistance at +5V, 4Ω max channel-to-channel on-resistance match, and rail-to-rail signal handling from GND to V+ - used in battery-powered audio routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4612CSD+ datasheet, MAX4612CSD+ pinout, MAX4612CSD+ application, or MAX4612CSD+ equivalent, this page delivers verified electrical specs, truth-table–validated switching behavior, package-specific thermal derating, leakage performance across temperature, and real-world design context for signal-path selection in portable and industrial systems.
Technical Context
The MAX4612CSD+ implements four independent CMOS transmission gates controlled by TTL/CMOS-compatible digital inputs (VIN_H = 2.4V, VIN_L = 0.8V at +5V supply), supporting single-supply operation from +2V to +12V. Each switch features matched on-resistance (ΔRON ≤ 4Ω) and flat on-resistance (≤18Ω variation) over its full analog signal range.
It handles bidirectional analog signals from GND to V+, with <2nA off-leakage at +85°C and >2kV ESD protection per Method 3015.7. The device uses standard silicon-gate CMOS process architecture with integrated substrate biasing tied to V+.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612CUD+ | Same electrical specs, but in 14-pin TSSOP package - 0.65mm pitch vs. SO's 1.27mm; 500mW power dissipation vs. 640mW | Better suited for space-constrained layouts; lower thermal mass limits sustained current in high-duty-cycle switching | Select MAX4612CUD+ when board area is constrained and thermal load is moderate |
| MAX4612CPD+ | Identical function and specs, but in 14-pin plastic DIP - through-hole mounting, 800mW power rating, no RoHS exemption for lead | Preferred for prototyping, manual assembly, or legacy industrial backplanes requiring through-hole reliability | Choose MAX4612CPD+ for hand-soldered evaluation or high-reliability through-hole deployments |
Compared with MAX4612CSD+, the TSSOP variant offers higher density but reduced thermal margin, while the DIP version trades miniaturization for mechanical robustness and ease of rework - all three share identical switching characteristics, logic thresholds, and leakage performance.

FAQ
What is the maximum supply voltage for MAX4612CSD+?
The absolute maximum V+ rating for MAX4612CSD+ is +13V referenced to GND. Operation up to +12V is fully specified in the datasheet, with on-resistance dropping to 30Ω typical at that rail. Exceeding +13V risks permanent damage, and even ±5% 12V supplies may produce transient overshoot beyond this limit - proper bypassing with ≥0.1µF ceramic capacitor near the V+ pin is mandatory for reliable +12V use. MAX4612CSD+ must never be operated with V+ below -0.3V.
Does MAX4612CSD+ support bidirectional analog signal flow?
Yes, MAX4612CSD+ supports fully bidirectional analog signal flow on all COM–NO and COM–NC paths. Its CMOS transmission-gate architecture imposes no intrinsic directionality - signal polarity and current direction are determined solely by external circuit biasing. This enables flexible use in both source-driven and sink-driven configurations, such as multiplexing sensor outputs into an ADC or routing DAC outputs to multiple loads. MAX4612CSD+ maintains matched on-resistance and flatness regardless of signal direction.
How does temperature affect on-resistance in MAX4612CSD+?
On-resistance in MAX4612CSD+ increases with temperature: at +25°C and +5V supply, RON is typically 60Ω; at +85°C it rises to ~80Ω; and at -40°C it drops to ~45Ω. This variation is monotonic and predictable, with datasheet graphs showing RON vs. VCOM curves across -40°C to +85°C. For precision applications, designers should account for this drift - especially in wide-temperature industrial environments where RON change can impact gain accuracy. MAX4612CSD+ guarantees ≤100Ω max across 0°C to +70°C operating range.
Can MAX4612CSD+ be used with a 3V supply?
Yes, MAX4612CSD+ is fully operational down to +2V supply, with verified performance at +3V. At +3V, on-resistance increases to 175Ω (typical), off-leakage remains <30nA, and logic thresholds adjust to VIN_H = 1.0V / VIN_L = 0.5V - maintaining compatibility with 3V microcontrollers. Switching times lengthen (tON = 140ns typ), and bandwidth reduces, but rail-to-rail signal handling (0V to +3V) and low THD (0.009%) are preserved. MAX4612CSD+ is widely deployed in coin-cell–powered IoT sensors leveraging this 3V capability.
What is the meaning of "two NO and two NC" in MAX4612CSD+?
MAX4612CSD+ integrates four independent SPST switches: pins 1 & 8 are normally open (NO), conducting only when their respective IN1/IN3 inputs are HIGH; pins 3 & 11 are normally closed (NC), conducting when IN2/IN4 are LOW and opening when HIGH. This hybrid configuration enables break-before-make or make-before-break sequencing in safety-critical paths - for example, isolating a sensor before connecting a calibration source. Unlike MAX4610 (four NO) or MAX4611 (four NC), MAX4612CSD+ provides inherent redundancy and fail-safe routing options.
