Product details
Overview
MAX4669ESE+ 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. It is used in reed relay replacement, test equipment, and audio-signal routing where low distortion and high reliability are required.
For engineers reviewing the MAX4669ESE+ datasheet, MAX4669ESE+ pinout, MAX4669ESE+ application, or MAX4669ESE+ equivalent, key selection criteria include guaranteed break-before-make timing (5–30ns), matched on-resistance (≤0.4Ω), off-isolation (−60dB), crosstalk (−66dB), and −40°C to +85°C industrial temperature rating.
Technical Context
The MAX4669ESE+ implements two independent CMOS transmission gates in a single 16-pin narrow SOIC package, each with dedicated logic-controlled IN1/IN2 inputs driving complementary NMOS/PMOS stacks. Its break-before-make behavior is hardware-guaranteed via internal timing control, eliminating external sequencing requirements for NC/NO co-location.
It supports both dual-supply (±4.5V to ±20V) and single-supply (+4.5V to +36V) configurations, with TTL/CMOS-compatible logic thresholds (0.8V/2.4V) referenced to VL. Analog signal range spans V− to V+, enabling true rail-to-rail operation - critical for precision instrumentation and avionics signal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max at ±15V dual supply - ensures minimal voltage drop and power loss in signal path |
| RON Match (∆RON) | 0.4Ω max between channels - enables precise differential or matched-path switching without gain error |
| Break-Before-Make Delay | 5–30ns - prevents momentary short-circuit during channel transition in mixed NO/NC configuration |
| Off-Isolation | −60dB at 1MHz - suppresses leakage between inactive switch and signal path in multiplexed systems |
| Crosstalk | −66dB at 1MHz - maintains signal integrity when routing multiple analog channels on shared PCB traces |
| Charge Injection | 450pC max - limits voltage glitch on high-impedance nodes (e.g., sample-and-hold capacitors) |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports wide-range industrial and test-equipment rails |
Pinout & Package
MAX4669ESE+ is housed in a 16-pin narrow SOIC (SO/DIP) package with 1.27mm pitch, rated for −40°C to +85°C operation. Pin 1 is NC (no internal connection); pins 1, 3, 6, 8, 10, and 15 are all NC and must be tied to GND for optimal off-isolation performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connection (NC) | Not internally connected; tie to GND to reduce parasitic capacitance and improve off-isolation |
| 2, 7 | Logic Input (IN1, IN2) | TTL/CMOS-compatible digital control inputs; active-high logic drives respective switch |
| 4 | Negative Supply (V−) | Analog negative rail input; connect to GND for single-supply operation |
| 5 | Ground (GND) | Reference return for logic and analog sections; separate grounding improves noise immunity |
| 9, 16 | Normally Closed (NC1, NC2) | Closed when corresponding INx = LOW; MAX4669 uses only NC1 (pin 9) and NO1 (pin 16) |
| 11, 14 | Common Terminals (COM1, COM2) | Analog signal input/output nodes; bidirectional, rail-to-rail capable |
| 12 | Logic Supply (VL) | Independent logic voltage reference (typically +5V); decouples logic threshold from analog rails |
| 13 | Positive Supply (V+) | Analog positive rail input; supports up to +36V in single-supply mode |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed Break-Before-Make | Hardware-enforced 5–30ns delay prevents simultaneous conduction in MAX4669's mixed NO/NC topology |
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ (e.g., ±20V or 0V to +36V), preserving full dynamic range in precision circuits |
| Low On-Resistance Flatness | 0.5Ω max variation over full signal range - ensures consistent gain and linearity across input voltage swing |
| ESD Protection | ≥2kV per Human Body Model (Method 3015.7) - enhances robustness in automated test and field-deployed equipment |
| Low Off-Leakage Current | 0.5nA max at +85°C - minimizes error in high-impedance sensor interfaces and sample-and-hold applications |

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 | Single-supply only (±5V to ±22V not supported); 1.3Ω RON; no guaranteed break-before-make | Better for low-voltage, low-RON precision instrumentation; unsuitable for dual-supply avionics or ATE | Select when RON <1.5Ω is mandatory and break-before-make is managed externally |
| TS5A23157DCUR | Lower voltage range (2.5V–5.5V V+); 0.9Ω RON; no dual-supply support; −40°C to +85°C rating matches | Optimized for portable battery-powered audio; lacks rail-to-rail analog range and high-voltage isolation | Choose for cost-sensitive consumer audio where ±15V operation is unnecessary |
Compared with ADG1419BRUZ and TS5A23157DCUR, the MAX4669ESE+ uniquely combines guaranteed break-before-make, ±20V dual-supply support, and industrial temperature range - making it the only option for safety-critical or wide-rail test and avionics applications.

FAQ
What is the guaranteed break-before-make timing specification for MAX4669ESE+?
The MAX4669ESE+ guarantees a break-before-make time delay of 5ns minimum to 30ns maximum between its NC and NO channels. This hardware-enforced timing prevents momentary short-circuit during state transitions and is validated across −40°C to +85°C and full supply voltage range. The MAX4669ESE+ achieves this without external circuitry, distinguishing it from generic dual switches.
Does MAX4669ESE+ support true rail-to-rail analog signal operation?
Yes, the MAX4669ESE+ supports rail-to-rail analog signal handling from V− to V+, including ±20V dual-supply and 0V to +36V single-supply configurations. This is confirmed by Absolute Maximum Ratings (VCOM_, VNO_, VNC_ = V− to V+) and Electrical Characteristics tables showing full-range operation with ≤2.5Ω RON and ≤0.5nA leakage at extremes.
What is the purpose of the NC pins (1, 3, 6, 8, 10, 15) on MAX4669ESE+?
Pins 1, 3, 6, 8, 10, and 15 on the MAX4669ESE+ are No Connect (NC) terminals - not internally bonded. Per Maxim's Pin Description table, they must be tied to GND to minimize stray capacitance and improve off-isolation performance. Leaving them floating degrades high-frequency isolation and increases crosstalk beyond −60dB.
Can MAX4669ESE+ operate from a single +12V supply?
Yes, the MAX4669ESE+ operates from +4.5V to +36V single supply. With V− tied to GND and V+ = +12V, it delivers 4Ω max on-resistance, −66dB crosstalk, and 500ns max turn-on time. Logic inputs remain TTL/CMOS-compatible via VL = +5V, and analog signals swing 0V to +12V - validated in Single-Supply Electrical Characteristics tables.
How does MAX4669ESE+ differ from MAX4667ESE+ and MAX4668ESE+?
The MAX4669ESE+ integrates one normally closed (NC1, pin 9) and one normally open (NO1, pin 16) switch with guaranteed break-before-make timing. In contrast, MAX4667ESE+ has two NC switches, and MAX4668ESE+ has two NO switches - neither provides break-before-make. All three share identical RON, leakage, supply range, and package, but only MAX4669ESE+ enables safe channel handover in mixed-path systems.
