Product details
Overview
MAX4667CSE from Maxim Integrated is a dual, normally closed (NC), single-pole single-throw (SPST) CMOS analog switch with 2.5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling up to ±20V. It delivers matched on-resistance (≤0.4Ω), flat on-resistance (≤0.5Ω), and <5nA off-leakage at +85°C-enabling high-fidelity signal routing in automated test equipment and audio systems.
For engineers reviewing the MAX4667CSE datasheet, MAX4667CSE pinout, MAX4667CSE application, or MAX4667CSE equivalent, key selection criteria include guaranteed break-before-make timing only for MAX4669 (not applicable here), NC-only topology, SOIC-16 narrow-body package compatibility, and TTL/CMOS-compatible logic thresholds at ±15V or +12V supply rails.
Technical Context
The MAX4667CSE implements two independent NC SPST switches using high-voltage CMOS process technology, supporting true rail-to-rail analog signal ranges from V− to V+ (±20V dual or 0V to +36V single). Its control architecture uses non-inverting logic inputs referenced to VL, with guaranteed 0.8V/2.4V TTL/CMOS thresholds across full temperature range.
Each switch features matched and flat on-resistance over its entire signal range, low charge injection (450pC typical), and high off-isolation (−60dB at 1MHz). The device avoids internal sneak paths by isolating unused pins (N.C.) and requires no external protection diodes when power sequencing is observed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and signal attenuation in precision analog paths |
| RON Match Between Channels | 0.4Ω max - enables accurate differential or ratiometric signal switching without gain error |
| RON Flatness | 0.5Ω max over full signal range - maintains consistent gain and linearity across ±20V input swing |
| Off-Leakage Current | 0.5nA max at +85°C - preserves DC accuracy in high-impedance sensor or calibration circuits |
| Supply Range | ±4.5V to ±20V dual or +4.5V to +36V single - supports industrial, test, and avionics power architectures |
| Turn-On/Off Time | 400ns / 300ns typical - suitable for moderate-speed multiplexing (e.g., <1MHz channel scanning) |
| ESD Protection | >2kV per Method 3015.7 - enhances robustness during board handling and system integration |
Pinout & Package
MAX4667CSE is housed in a 16-pin narrow SOIC (SO/DIP) package with 1.27mm pitch, JEDEC MS-012AC compliant, and rated for 0°C to +70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connect (N.C.) | Not internally bonded; tie to GND for improved off-isolation and noise immunity |
| 2, 7 | IN1, IN2 | Digital control inputs for SW1 and SW2; TTL/CMOS-compatible, referenced to VL |
| 4 | V− | Negative analog supply rail; connect to GND for single-supply operation |
| 5 | GND | Analog and digital ground reference; separate grounding improves PSRR and crosstalk |
| 9, 16 | NC1, NC2 | Normally closed switch terminals - conduct to COM when IN = LOW |
| 11, 14 | COM1, COM2 | Common analog terminals - bidirectional signal path between NC and COM |
| 12 | VL | Logic supply input - sets logic threshold; typically +5V, independent of analog supplies |
| 13 | V+ | Positive analog supply rail - defines upper signal limit and powers analog switch core |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ (±20V dual or 0–36V single), eliminating level-shifting in wide-dynamic-range systems |
| Guaranteed RON match & flatness | ≤0.4Ω channel-to-channel mismatch and ≤0.5Ω variation over full signal range - critical for instrumentation-grade multiplexing |
| TTL/CMOS-compatible logic inputs | Fixed 0.8V/2.4V thresholds - ensures reliable switching with standard microcontroller GPIOs even under varying supply conditions |
| Low off-leakage current | ≤0.5nA at +85°C - prevents drift in high-impedance sensor front-ends and precision integrators |
| High off-isolation | −60dB at 1MHz - suppresses crosstalk between active and inactive channels in dense signal routing |
Applications
| Reed Relay Replacement | Audio-Signal Routing |
|---|---|

IC Role / Device Role / Timing Role: Dual NC switch handling tip/ring continuity and tone injection while maintaining FCC Part 68 compliance. Use Value: ±20V dual-supply support accommodates legacy -48V telephony rails; 5nA leakage prevents false off-hook detection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4668CSE | Two normally open (NO) switches instead of NC; identical RON, leakage, and supply specs | Used where default-open signal paths are required (e.g., safety interlocks, default-disconnect sensors) | Select MAX4668CSE when circuit logic demands open-circuit default state rather than closed-circuit default. |
| ADG1419BRUZ | Single-supply only (±15V max), 1.3Ω RON, higher 12pF COFF, but offers guaranteed break-before-make | Better suited for low-RON single-supply systems where BMB timing is mandatory (e.g., FPGA I/O banks) | Choose ADG1419BRUZ only if single-supply operation and sub-2Ω RON outweigh need for dual-supply flexibility and NC topology. |
Compared with MAX4667CSE, MAX4668CSE provides identical electrical performance but inverted switch logic (NO vs. NC), while ADG1419BRUZ trades dual-supply capability and NC configuration for lower on-resistance and integrated break-before-make-making it unsuitable as a drop-in replacement but viable for redesigns prioritizing RON and BMB assurance.

FAQ
What is the maximum allowable supply voltage for MAX4667CSE?
The MAX4667CSE supports absolute maximum ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V, with recommended operating range of ±4.5V to ±20V dual supply or +4.5V to +36V single supply. Exceeding ±20V or +36V risks permanent damage and violates the specified operational envelope defined in the datasheet.
Does MAX4667CSE support break-before-make switching?
No, MAX4667CSE does not support break-before-make operation. That feature is guaranteed only for the MAX4669 variant (one NC + one NO switch). The MAX4667CSE contains two independent normally closed switches with no timing coordination between them-each operates asynchronously based on its own INx input.
Can MAX4667CSE be used with a single +5V supply?
Yes, MAX4667CSE can operate from a +5V single supply, but only if V− is tied to GND and the analog signal range remains within 0V to +5V. Note that RON increases to 4Ω max under +5V single-supply conditions (vs. 2.5Ω at ±15V), and rail-to-rail capability is limited to 0V–V+.
What is the purpose of the VL pin on MAX4667CSE?
The VL pin on MAX4667CSE sets the logic threshold reference for IN1 and IN2 inputs, enabling TTL/CMOS compatibility across diverse supply configurations. When VL = +5V, logic thresholds are fixed at 0.8V (low) and 2.4V (high), regardless of V+ or V− values-ensuring reliable control from standard digital ICs even with ±15V analog rails.
How should unused N.C. pins be handled on MAX4667CSE?
All N.C. pins (1, 3, 6, 8, 10, 15) on MAX4667CSE must be connected to GND via low-impedance traces. This practice minimizes parasitic capacitance, improves off-isolation by >10dB, and reduces high-frequency crosstalk-critical for maintaining signal integrity in multi-channel routing applications.
