Product details
Overview
MAX14594EEWL+T from Maxim Integrated is a high-density, ±5V-capable double-pole/double-throw (DPDT) analog switch with Beyond-the-Rails™ operation, enabling distortion-free signal switching from −5.5V to +5.5V even when powered by as low as +1.6V. It features integrated 500Ω shunt resistors at NO1/NO2 terminals for click-and-pop suppression in audio paths, 0.2Ω typical on-resistance at 2.5V, and operates over −40°C to +85°C in portable audio routing applications.
For engineers reviewing the MAX14594EEWL+T datasheet, MAX14594EEWL+T pinout, MAX14594EEWL+T application, or MAX14594EEWL+T equivalent, key selection criteria include its ±5.5V analog signal range independent of VCCEN, 30µA supply current at 1.6V, break-before-make timing, ESD robustness (±15kV HBM on COM/NO/NC), and wafer-level package compatibility with space-constrained mobile designs.
Technical Context
The MAX14594EEWL+T implements two independent DPDT switches controlled by a single CB logic input, supporting bidirectional analog signal routing with full rail-to-rail and beyond-the-rails capability. Its internal shunt resistors (500Ω typ) are activated only when NO terminals are disconnected from COM, enabling automatic discharge of AC-coupling capacitors to suppress audio transients.
Switching behavior follows strict break-before-make timing (0–10µs at 3.3V), ensuring no momentary short between NC and NO paths. All analog pins tolerate −6V to +6V continuously, while digital control (CB) accepts 0.4V/1.4V logic thresholds across the full 1.6V–5.5V supply range, allowing direct GPIO interfacing without level shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | −5.5V to +5.5V - supports audio/video signals beyond supply rails without distortion or clipping |
| On-Resistance (RON) | 0.2Ω typ at VCCEN = 2.5V - enables low insertion loss and minimal THD+N (0.001%) in audio paths |
| Supply Voltage Range | +1.6V to +5.5V - allows direct powering from low-voltage GPIOs or battery rails |
| Shunt Resistance | 500Ω typ - discharges precharged coupling caps to eliminate audible pop during audio source switching |
| ESD Protection | ±15kV HBM on COM/NO/NC - survives handling and system-level ESD events without latchup or degradation |
| Turn-On/Off Time | 5µs/1µs typ at RL = 50Ω - ensures fast, glitch-free channel reconfiguration in real-time audio routing |
| Off-Leakage Current | ±400nA max at TA = −40°C to +85°C - preserves DC bias integrity in precision sensor or audio front-end circuits |
Pinout & Package
MAX14594EEWL+T uses a 1.2mm × 1.2mm, 0.4mm pitch, 9-bump wafer-level package (WLP) with bottom-side solder bumps. The package is RoHS-compliant and optimized for ultra-compact PCB layouts in smartphones and wearables.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| A2 | CB | Digital control bit - low = COM_ to NC_; high = COM_ to NO_; compatible with 1.6V logic |
| A3 | NC2 | Normally closed terminal for Switch 2 - connects to COM2 when CB = low |
| B1 | COM1 | Common terminal for Switch 1 - bidirectional analog I/O path shared with NC1/NO1 |
| B2 | GND | Ground reference - must be connected directly to low-impedance system ground plane |
| B3 | COM2 | Common terminal for Switch 2 - bidirectional analog I/O path shared with NC2/NO2 |
| C1 | NO1 | Normally open terminal for Switch 1 - connects to COM1 when CB = high; includes internal 500Ω shunt to GND |
| C2 | VCCEN | Positive supply input - bypass with 0.1µF capacitor close to pin; powers internal logic and analog switches |
| C3 | NO2 | Normally open terminal for Switch 2 - connects to COM2 when CB = high; includes internal 500Ω shunt to GND |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX14589EEWL+T | No internal shunt resistors on NO1/NO2 - lacks click-and-pop suppression capability | Suitable for non-audio signal routing (e.g., video, sensor mux) where transient suppression is unnecessary | Select MAX14589EEWL+T only when audio pop elimination is not required and cost optimization is prioritized |
| TMUX1574RTER | Higher RON (0.5Ω typ), no Beyond-the-Rails operation (limited to VCCEN ±0.3V), ±4kV HBM ESD rating | Requires external clamping for ±5V signals; unsuitable for direct coupling to AC-coupled audio amplifiers | Choose TMUX1574RTER only for lower-voltage, non-audio applications where WLP size and ESD margin are secondary concerns |
Compared with MAX14589EEWL+T and TMUX1574RTER, MAX14594EEWL+T uniquely combines ±5.5V signal handling, integrated shunt-based pop suppression, and industry-leading ±15kV HBM protection - making it the only option qualified for high-fidelity, space-constrained mobile audio routing without external circuitry.

FAQ
What is the maximum analog signal voltage the MAX14594EEWL+T can handle without distortion?
The MAX14594EEWL+T supports analog signals from −5.5V to +5.5V relative to GND, regardless of VCCEN level - a feature called Beyond-the-Rails™ operation. This allows distortion-free passage of audio or video signals that exceed the supply voltage range, such as precharged AC-coupled audio lines. The specification is guaranteed over the full −40°C to +85°C operating temperature range and applies to all NC_, NO_, and COM_ pins.
Does the MAX14594EEWL+T require an external power supply for its shunt resistors?
No - the shunt resistors in the MAX14594EEWL+T are fully integrated and powered internally. They activate automatically when CB is low (connecting NC_ to COM_) and NO_ terminals are unconnected, discharging any residual charge on AC-coupling capacitors. No external bias, control, or power is needed - the 500Ω shunt resistance is inherent to the MAX14594EEWL+T silicon design and functions without additional components.
Can the MAX14594EEWL+T operate with a 1.6V GPIO driving the CB pin?
Yes - the MAX14594EEWL+T specifies VIH = 1.4V min and VIL = 0.4V max across its entire +1.6V to +5.5V supply range, making it fully compatible with 1.6V, 1.8V, and 3.3V GPIOs. When VCCEN = 1.6V, the CB input threshold remains valid, and ICC draws only 30µA typ, enabling direct microcontroller control without level-shifting circuitry or additional power domains.
How does the MAX14594EEWL+T behave when VCCEN is unpowered?
When VCCEN is unpowered (0V), the MAX14594EEWL+T enters a high-impedance state: all analog ports (NC_, NO_, COM_) remain functional and can safely withstand −5.5V to +5.5V signals without damage or leakage. The internal switches are disabled, and digital inputs (CB) retain ±2kV HBM ESD protection. This fail-safe behavior allows hot-swap compatibility and safe operation during power sequencing in multi-rail systems.
Is the MAX14594EEWL+T pin-compatible with the MAX14589EEWL+T?
Yes - MAX14594EEWL+T and MAX14589EEWL+T share identical 9-bump WLP packaging, pinout, footprint, and electrical interface. The only functional difference is the presence of internal shunt resistors in the MAX14594EEWL+T (absent in MAX14589EEWL+T); all other timing, leakage, RON, and ESD specifications match. PCB layouts designed for MAX14589EEWL+T can be reused for MAX14594EEWL+T without modification.
