Product details
Overview
MAX4665ESE+TG035 from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with normally open (NO) configuration, designed for rail-to-rail signal routing in precision analog systems. It delivers 5Ω maximum on-resistance, 0.5Ω maximum on-resistance match between channels, and 5nA maximum off-leakage current at +85°C, enabling low-distortion audio-signal routing and reed-relay replacement in test equipment.
For engineers reviewing the MAX4665ESE+TG035 datasheet, MAX4665ESE+TG035 pinout, MAX4665ESE+TG035 application, or MAX4665ESE+TG035 equivalent, key selection criteria include guaranteed RON flatness (0.5Ω max over ±10V signal range), TTL/CMOS-compatible logic thresholds (+0.8V / +2.4V), and dual-supply operation (±4.5V to ±20V) or single-supply operation (+4.5V to +36V).
Technical Context
The MAX4665ESE+TG035 implements a CMOS-based SPST switch architecture with four independent NO channels, each featuring matched and flat on-resistance across its full analog signal range. Its internal protection diodes clamp signals exceeding V+ or V−, and it guarantees break-before-make timing only in the MAX4666 variant-not applicable here.
Control inputs accept TTL/CMOS logic levels across full supply ranges, and the device supports rail-to-rail analog signal handling from V− to V+, with leakage currents fully tested at +85°C and guaranteed by correlation at +25°C. Dynamic performance includes 100ns–250ns turn-off time and −60dB crosstalk at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 5Ω max - ensures minimal voltage drop and signal attenuation in low-level analog paths |
| RON match | 0.5Ω max - enables precise channel-to-channel gain matching in multiplexed instrumentation |
| RON flatness | 0.5Ω max over ±10V - maintains consistent signal integrity across full input swing |
| Off-leakage current | 5nA max at +85°C - preserves accuracy in high-impedance sensor front-ends and sample-hold circuits |
| Supply range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, avionics, and telecom power architectures |
| Logic thresholds | +0.8V low / +2.4V high - ensures reliable interface with 3.3V/5V microcontrollers without level-shifting |
| Crosstalk | −60dB at 1MHz - prevents inter-channel interference in multi-channel audio or data acquisition |
Pinout & Package
MAX4665ESE+TG035 is housed in a 16-pin narrow SOIC (SO/DIP) package with exposed pad (TG035 suffix denotes tape-and-reel packaging in narrow SO format). Pin 1 is located at the top-left corner adjacent to the index notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic turns corresponding NO switch ON |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals; connect to signal source or load return path |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog outputs; conduct to COM when IN = high |
| 4 | V− | Negative analog supply; tie to GND for single-supply operation |
| 5 | GND | Digital ground reference; must be connected even in dual-supply mode |
| 12 | VL | Logic supply input; accepts +2.7V to +5.5V, independent of analog supplies |
| 13 | V+ | Positive analog supply; defines upper rail for rail-to-rail analog signal range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping-critical for ±15V op-amp interfaces and audio line drivers |
| Guaranteed RON flatness | 0.5Ω max variation over ±10V range-enables distortion-free switching in high-fidelity audio routing |
| TTL/CMOS-compatible inputs | +0.8V / +2.4V thresholds ensure direct interfacing with FPGA I/O banks and MCU GPIOs at 3.3V or 5V |
| ESD protection | >2kV per Method 3015.7-reduces need for external transient suppression in field-deployed test gear |
| Low charge injection | 25pC typical-minimizes voltage glitches in sample-and-hold and ADC multiplexer applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG465BRUZ | 5.5Ω max RON, −40°C to +85°C, 16-TSSOP; requires VL = V+ for logic compatibility | Higher RON drift vs. temperature; lacks guaranteed RON flatness spec | Prefer MAX4665ESE+TG035 when flat RON over signal range is required for audio fidelity |
| TS5A3157DCKR | Single-channel, 0.75Ω max RON, +1.65V to +5.5V supply only; not rated for ±15V operation | Limited to low-voltage portable systems; cannot replace in industrial dual-supply designs | Use TS5A3157DCKR only in 3.3V battery-powered signal routing-MAX4665ESE+TG035 remains necessary for wide-supply, quad-channel needs |
Compared with ADG465BRUZ and TS5A3157DCKR, the MAX4665ESE+TG035 uniquely combines quad-channel integration, ±20V dual-supply capability, guaranteed RON flatness, and 5nA leakage at +85°C-making it the only option qualified for high-accuracy, wide-dynamic-range analog multiplexing in harsh environments.

FAQ
What is the operating temperature range of the MAX4665ESE+TG035?
The MAX4665ESE+TG035 is rated for operation from −40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet, and applies specifically to the "E" grade suffix in the part number. The device undergoes 100% testing at maximum hot temperature for leakage parameters.
Does the MAX4665ESE+TG035 support single-supply operation?
Yes, the MAX4665ESE+TG035 supports single-supply operation from +4.5V to +36V. In this configuration, V− is connected to GND, V+ supplies the positive rail, and VL may be tied to V+ or driven separately at +2.7V to +5.5V. Electrical Characteristics tables explicitly list single-supply test conditions (e.g., V+ = +12V, V− = 0).
Is the MAX4665ESE+TG035 pin-compatible with the MAX4664ESE+TG035?
No-the MAX4665ESE+TG035 and MAX4664ESE+TG035 share identical pinouts and package but differ in switch configuration: MAX4665 has four normally open (NO) switches, while MAX4664 has four normally closed (NC) switches. Swapping them without logic inversion will invert functional behavior (e.g., signal path becomes open instead of closed).
What is the maximum continuous current rating per switch in the MAX4665ESE+TG035?
The MAX4665ESE+TG035 supports ±100mA continuous current through each COM–NO path, as specified in the Absolute Maximum Ratings table. This rating applies to all pins including COM_, NO_, and NC_ terminals, and is valid across the full operating temperature range when derated per package power dissipation limits.
Does the MAX4665ESE+TG035 include break-before-make functionality?
No-break-before-make timing is guaranteed only for the MAX4666 variant (which integrates two NO and two NC switches). The MAX4665ESE+TG035 is a pure normally open quad SPST switch with no internal timing control between channels; simultaneous switching of multiple channels is possible but not coordinated for break-before-make transitions.
