Product details
Overview
MAX4702ETE+ from Maxim Integrated is a quad single-pole/double-throw (SPDT) analog switch IC designed for low-voltage signal routing in space-constrained systems. It operates from a single +1.8V to +5.5V supply, delivers 40Ω max on-resistance at +5V, features 1.0V logic threshold with dedicated VL pin, and achieves tON = 18ns (max) and tOFF = 9ns (max) at +5V - enabling high-fidelity audio/video switching in battery-powered handheld devices.
For engineers reviewing the MAX4702ETE+ datasheet, MAX4702ETE+ pinout, MAX4702ETE+ application, or MAX4702ETE+ equivalent, key selection criteria include guaranteed break-before-make timing, rail-to-rail analog signal handling (0V to V+), 250MHz -3dB bandwidth, <1nA leakage at +85°C, and compatibility with 1.5V logic supplies via VL input.
Technical Context
The MAX4702ETE+ implements four independent SPDT switches controlled by a single digital input (IN), with separate VL pin enabling 1.0V VIH logic threshold under +1.5V logic supply. Its CMOS architecture ensures bidirectional signal flow, rail-to-rail analog range, and break-before-make switching to prevent momentary shorting during state transitions.
Each channel exhibits tightly matched on-resistance (≤4Ω max ΔRON) and flatness (≤10Ω max RFLAT(ON) at +5V), critical for maintaining signal integrity across varying common-mode voltages. The device supports full-spectrum analog signals up to 250MHz with -76dB off-isolation and -79dB crosstalk at 1MHz, making it suitable for high-fidelity audio and broadband video routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct integration with Li-ion, 3.3V, and 5V system rails without level-shifting. |
| On-Resistance (RON) | 40Ω max at +5V - ensures minimal insertion loss and voltage drop for precision analog signal paths. |
| On-Resistance Match (ΔRON) | 4Ω max between channels - preserves amplitude balance in multi-channel audio or differential signal routing. |
| Turn-On/Off Time | tON = 18ns max, tOFF = 9ns max at +5V - supports fast multiplexing in real-time communication and data acquisition systems. |
| -3dB Bandwidth | 250MHz - accommodates HD video signals (e.g., HDMI auxiliary, RGB, YPbPr) without attenuation. |
| Logic Threshold (VIH/VIL) | 1.0V / 0.4V with VL = +1.5V - allows direct interfacing with ultra-low-voltage microcontrollers and ASICs. |
| Leakage Current | ±1nA max at +85°C - maintains signal fidelity in high-impedance sensor interfaces and battery-critical standby modes. |
Pinout & Package
MAX4702ETE+ uses a 16-pin 3mm × 3mm TQFN-EP package with exposed pad connected to GND for thermal and EMI performance. Pin numbering follows standard top-view orientation with pin 1 at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO1) | Analog Switch 1 Normally Open | Output terminal closed to COM1 when IN = high; bidirectional signal path. |
| 2 (V+) | Positive Supply Input | Primary power rail for analog and core logic; must be applied before analog signals per sequencing guidelines. |
| 3 (NC4) | Analog Switch 4 Normally Closed | Output terminal closed to COM4 when IN = low; unused in SPDT configuration unless NC path required. |
| 4 (COM4) | Analog Switch 4 Common Terminal | Signal input/output node shared between NO4 and NC4; supports rail-to-rail voltage swing (0V to V+). |
| 5 (NO4) | Analog Switch 4 Normally Open | Output terminal closed to COM4 when IN = high; matches NO1–NO3 behavior for consistent routing. |
| 6 (VL) | Logic Power-Supply Input | Provides reference for 1.0V VIH threshold; must be ≥1.5V and powered after V+ for reliable logic operation. |
| 7 (NC3) | Analog Switch 3 Normally Closed | Output terminal closed to COM3 when IN = low; enables fail-safe or default-path configurations. |
| 8 (COM3) | Analog Switch 3 Common Terminal | Third independent signal path common node; electrically isolated from other COMx pins. |
| 9 (NO3) | Analog Switch 3 Normally Open | Output terminal closed to COM3 when IN = high; identical electrical specs to NO1–NO4. |
| 10 (COM1) | Analog Switch 1 Common Terminal | First signal path common node; pin 16 is COM1 in alternate pinout - confirmed as COM1 in MAX4702-specific diagram. |
| 11 (NC1) | Analog Switch 1 Normally Closed | Default path for Switch 1 when IN = low; complements NO1 for dual-path routing schemes. |
| 12 (COM2) | Analog Switch 2 Common Terminal | Second independent signal path common node; shares same RON and bandwidth specs as COM1/COM3/COM4. |
| 13 (IN) | Digital Control Input | Single logic input controlling all four SPDT switches simultaneously; active-high with VL-referenced thresholds. |

| 15 (NC2) | Analog Switch 2 Normally Closed | Default path for Switch 2 when IN = low; enables redundant or backup signal routing. |
| 16 (GND) | Ground Reference | System ground return; exposed pad (EP) must be soldered to PCB GND plane for thermal dissipation and noise reduction. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | Higher on-resistance (1.8Ω typ at +5V), wider supply range (+5V to ±15V), no VL pin - requires 2.0V logic min. | Better suited for industrial PLC I/O modules needing bipolar supplies; less optimal for 1.5V logic systems. | Select ADG1414BRUZ when bipolar operation or higher voltage tolerance is required; avoid if 1.0V logic interface is mandatory. |
| TS5A3157DCUR | Lower on-resistance (0.75Ω typ at +3.3V), smaller 6-pin SC70 package, no VL pin, 1.65V–5.5V supply only. | Ideal for ultra-compact consumer wearables; lacks MAX4702ETE+'s 250MHz bandwidth and -76dB off-isolation. | Choose TS5A3157DCUR for size-constrained designs where bandwidth >100MHz is not required; verify crosstalk meets system SNR targets. |
Compared with ADG1414BRUZ and TS5A3157DCUR, the MAX4702ETE+ uniquely combines 1.0V logic compatibility via VL, 250MHz bandwidth, and guaranteed break-before-make in a 3mm × 3mm footprint - making it optimal for next-generation USB-C and battery-powered medical devices demanding both low-voltage logic and high-frequency signal integrity.

FAQ
What is the maximum supply voltage rating for MAX4702ETE+?
The MAX4702ETE+ has an absolute maximum supply voltage (V+) of +6V. Operation beyond this limit risks permanent damage. For reliable long-term performance, the recommended operating range is +1.8V to +5.5V. At +5V, the device delivers optimal switching speed (tON = 18ns max) and lowest on-resistance (40Ω max), making +5V the preferred supply for high-bandwidth applications like video routing.
Does MAX4702ETE+ require external level-shifting when interfaced with a 1.5V microcontroller?
No, the MAX4702ETE+ does not require external level-shifting when used with a 1.5V microcontroller. Its dedicated VL pin accepts +1.5V, establishing a 1.0V VIH and 0.4V VIL logic threshold. This allows direct connection to 1.5V GPIO outputs while guaranteeing reliable switching - a key differentiator from standard 3.3V-logic switches that would otherwise necessitate additional translation circuitry.
How does the break-before-make timing of MAX4702ETE+ prevent signal corruption?
The MAX4702ETE+ guarantees break-before-make timing of ≤2ns at +5V, ensuring the NC path opens fully before the NO path closes during state transitions. This eliminates momentary shorting between normally open and normally closed signal paths - critical in audio routing where even nanosecond shorts cause audible pops, and in USB-C alternate mode switching where bus contention could disrupt link training or damage PHY circuitry.
Can MAX4702ETE+ handle analog signals exceeding its V+ supply rail?
No, the MAX4702ETE+ cannot safely handle analog signals exceeding its V+ supply rail. Absolute maximum ratings specify that voltages on COM_, NO_, or NC_ pins must remain within -0.3V to (V+ + 0.3V). Exceeding this range risks latch-up or permanent damage. For overvoltage protection, external diodes (as shown in Figure 1 of the datasheet) must be added - though this reduces usable analog range by ~0.7V and slightly increases on-resistance.
What is the thermal performance advantage of the exposed pad in the MAX4702ETE+ TQFN package?
The exposed pad (EP) in the MAX4702ETE+ 3mm × 3mm TQFN package provides a low-thermal-resistance path from the die to the PCB ground plane. When soldered to a solid copper pour, it reduces junction-to-board thermal resistance by up to 40% versus non-exposed packages. This enables continuous operation at full 1666.7mW power dissipation (at TA = +70°C) and improves long-term reliability in thermally dense layouts like smartphone mainboards or medical handheld enclosures.
