Product details
Overview
The MAX4669CSE+ from Maxim Integrated is a dual SPST CMOS analog switch with one normally closed (NC) and one normally open (NO) channel, guaranteeing break-before-make operation. It features 2.5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail analog signal handling up to ±20V - ideal for reed relay replacement in automatic test equipment and audio-signal routing.
For engineers reviewing the MAX4669CSE+ datasheet, MAX4669CSE+ pinout, MAX4669CSE+ application, or MAX4669CSE+ equivalent, key selection criteria include guaranteed break-before-make timing (5–30ns), matched on-resistance (≤0.4Ω between channels), low off-leakage (≤0.5nA at +85°C), and TTL/CMOS-compatible logic thresholds (0.8V/2.4V) across supply configurations.
Technical Context
The MAX4669CSE+ implements complementary MOSFET topologies per channel to achieve rail-to-rail conduction and low charge injection (450pC typical). Its internal logic ensures strict break-before-make switching - critical for preventing momentary short-circuits during signal path reconfiguration in multiplexed test systems.
It supports dual-supply operation with independent V+ and V− pins (±4.5V to ±20V), plus VL logic supply (2.7V to 5.5V), enabling robust interfacing with mixed-voltage control systems while maintaining <0.5Ω on-resistance flatness over full signal range (±10V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - enables low insertion loss and minimal voltage drop in precision analog paths |
| RON Match (ΔRON) | 0.4Ω max - ensures matched gain/attenuation across dual channels in differential or parallel signal paths |
| RON Flatness | 0.5Ω max over ±10V - maintains consistent signal integrity across full input voltage swing |
| Break-Before-Make Delay | 5–30ns - prevents transient shorts during channel switching in safety-critical routing |
| Off-Leakage Current | 0.5nA max at +85°C - preserves high-impedance signal integrity in sensor front-ends and sample-hold circuits |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports industrial, avionics, and test-equipment power architectures |
| Logic Thresholds | VIN_H = 2.4V, VIN_L = 0.8V - ensures reliable TTL/CMOS compatibility without level-shifting at +12V or ±15V supplies |
Pinout & Package
MAX4669CSE+ uses a 16-pin narrow SOIC (SOIC-N) package with 1.27mm pitch, 10.3mm × 5.3mm body, and exposed pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connect (N.C.) | Unbonded die pads; connect to GND for improved off-isolation and EMI suppression |
| 2, 7 | Digital Control Input (IN1, IN2) | Active-high logic inputs controlling NO1/NC1 and NO2/NC2 states respectively |
| 4 | Negative Analog Supply (V−) | Reference for negative rail; tie to GND for single-supply operation |
| 5 | Ground (GND) | Logic and substrate reference; must be low-impedance for leakage and noise control |
| 9, 16 | Normally Closed Terminal (NC1, NC2) | Closed when corresponding INx = LOW; used for default-path continuity |
| 11, 14 | Common Terminal (COM1, COM2) | Analog signal I/O node shared between NO and NC paths per channel |
| 12 | Logic Supply (VL) | Independent 2.7V–5.5V supply for logic interface; decoupling required |
| 13 | Positive Analog Supply (V+) | Primary analog rail; supports up to +36V or ±20V differential |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Ensures no overlap between NO and NC conduction - eliminates signal shorting in fault-tolerant routing |
| Rail-to-rail analog signal handling | Supports input signals from V− to V+ without clipping - essential for ±15V instrumentation and audio line-level switching |
| ESD protection >2kV (HBM) | Meets MIL-STD-883 Method 3015.7 - reduces handling sensitivity and board-level ESD hardening requirements |
| Low charge injection (450pC) | Minimizes voltage glitch on sampled nodes - critical for precision data acquisition and sample-and-hold accuracy |
| Matched on-resistance flatness | 0.5Ω max variation across ±10V range - preserves amplitude fidelity in AC-coupled and DC-coupled signal chains |

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 |
|---|---|---|---|
| ADG1419BRUZ | Higher RON (3.8Ω typ), wider temp range (−40°C to +125°C), no guaranteed break-before-make | Better suited for high-temp industrial PLC I/O modules where timing overlap is acceptable | Select ADG1419BRUZ only if extended temperature rating outweighs need for guaranteed break-before-make |
| TS5A23157DGSR | Lower supply range (+1.65V to +5.5V), higher RON (0.9Ω min), no dual-supply capability | Targeted at low-voltage portable audio and USB-C accessory switching - incompatible with ±15V systems | Choose TS5A23157DGSR only for battery-powered 3.3V designs requiring ultra-low quiescent current |
Compared with ADG1419BRUZ and TS5A23157DGSR, the MAX4669CSE+ uniquely delivers guaranteed break-before-make timing, ±20V dual-supply operation, and 2.5Ω RON in a single device - making it the only option for safety-critical, wide-voltage, relay-replacement applications requiring zero overlap.

FAQ
What is the guaranteed break-before-make time for MAX4669CSE+?
The MAX4669CSE+ guarantees a break-before-make time delay of 5ns minimum to 30ns maximum under dual-supply conditions (V+ = +15V, V− = −15V, TA = TMIN to TMAX). This specification ensures no overlap between NO and NC conduction paths during state transitions, which is critical for preventing signal shorts in multiplexed test fixtures and safety-critical avionics interfaces. The timing is process- and temperature-compensated across the full operating range.
Can MAX4669CSE+ operate from a single +5V supply?
No, the MAX4669CSE+ cannot operate from a single +5V supply. Its absolute minimum single-supply voltage is +4.5V, but functional operation requires ≥+12V for guaranteed RON ≤4Ω and proper logic threshold margins. At +5V, the device may exhibit degraded on-resistance (>6Ω), increased leakage, and unreliable switching due to insufficient gate overdrive for the internal MOSFETs. Use +12V or higher for production designs.
Does MAX4669CSE+ support rail-to-rail analog signals with a +12V single supply?
Yes, the MAX4669CSE+ supports rail-to-rail analog signals from 0V to +12V when operated from a +12V single supply (V− tied to GND). The COM, NO, and NC terminals can swing continuously across the full supply range without clipping or distortion, verified by on-resistance flatness ≤0.5Ω over 0V to +10V. This enables direct interfacing with +12V op-amps and ADC drivers without level-shifting circuitry.
What is the maximum signal frequency supported by MAX4669CSE+?
The MAX4669CSE+ maintains usable performance up to 10MHz for on-isolation and crosstalk, with −60dB off-isolation and −66dB crosstalk measured at 1MHz. Above 5MHz, PCB layout becomes critical; off-isolation degrades rapidly above 300MHz due to capacitive coupling. For RF applications >10MHz, Maxim recommends the MAX440/MAX441 series, which are fully characterized to 160MHz and optimized for impedance-controlled layouts.
How should unused N.C. pins on MAX4669CSE+ be handled?
All six N.C. pins (1, 3, 6, 8, 10, 15) on the MAX4669CSE+ must be connected to GND via low-impedance traces. These pins are unconnected die pads; leaving them floating increases susceptibility to noise coupling and degrades off-isolation by up to 15dB. Grounding them improves high-frequency isolation and reduces EMI susceptibility - a requirement explicitly stated in the Maxim datasheet Pin Description table.
