Product details
Overview
The MAX395EAG.TG071 from Maxim Integrated is an 8-channel, serially controlled, single-pole/single-throw (SPST) analog switch IC with rail-to-rail signal handling, 100Ω max on-resistance (±5V supplies), matched channel resistance ≤5Ω, and <0.1nA off-leakage at +25°C. It operates from ±2.7V to ±8V dual supplies or +2.7V to +16V single supply, and is used in precision serial data-acquisition systems requiring low crosstalk (<−90dB) and high off-isolation (−90dB).
For engineers reviewing the MAX395EAG.TG071 datasheet, MAX395EAG.TG071 pinout, MAX395EAG.TG071 application, or MAX395EAG.TG071 equivalent, this page delivers verified electrical specs, SPI/Microwire™-compatible timing, daisy-chain capability via DOUT, reset-controlled power-up state, and TTL/CMOS logic compatibility across supply configurations.
Technical Context
The MAX395EAG.TG071 implements an 8-bit shift register interface synchronized to SCLK rising edges, with CS-driven latch update on its rising edge-fully compliant with SPI™ (CPOL=0, CPHA=0), QSPI™, and Microwire™ protocols. Its internal logic decodes serial DIN bits (D7–D0) to independently control eight bidirectional SPST switches, each with identical NO/COM terminal roles.
It features asynchronous RESET that forces all switches OFF and clears the shift register regardless of clock or CS state. Analog performance is maintained across wide supply ranges: on-resistance flatness ≤15Ω over ±3V signal range (dual ±5V), charge injection ≤10pC, and break-before-make delay ≤15ns-enabling accurate signal routing in multichannel instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation and gain error in precision analog paths. |
| On-Resistance Match | ≤5Ω max between channels - enables consistent channel-to-channel gain and offset in multiplexer applications. |
| Off-Leakage Current | 0.1nA max at +25°C - preserves signal integrity in high-impedance sensor front-ends and sample-hold circuits. |
| Rail-to-Rail Signal Range | VCOM/VNO = V− to V+ - supports full dynamic range utilization without clipping in bipolar or single-supply systems. |
| Serial Interface | SPI™/QSPI™/Microwire™-compatible 3-wire interface - simplifies microcontroller integration with no additional protocol translation. |
| Crosstalk & Isolation | <−90dB channel-to-channel crosstalk and −90dB off-isolation - critical for simultaneous multi-signal acquisition without interference. |
| Supply Range | ±2.7V to ±8V dual or +2.7V to +16V single - accommodates legacy industrial rails and modern low-voltage embedded systems. |
Pinout & Package
MAX395EAG.TG071 is packaged in a 24-pin narrow plastic DIP (Dual In-line Package) with 0.3-inch body width and standard through-hole mounting. Pin 1 is marked with a notch or dot; pin numbering follows counter-clockwise convention from top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SCLK (Pin 1) | Serial clock input | Drives synchronous data capture on rising edge; supports up to 2.1MHz operation with defined setup/hold timing. |
| V+ (Pin 2) | Positive analog supply | Sets upper analog voltage limit; must be ≥2.7V above GND or V− in dual-supply mode. |
| DIN (Pin 3) | Serial data input | Accepts 8-bit control word (D7–D0); D7 is MSB loaded first during CS low period. |
| GND (Pin 4) | Digital ground reference | Reference for logic inputs only; analog signals are referenced solely to V+ and V−. |
| NO0–NO7 (Pins 5,7,9,11,14,16,18,20) | Normally open analog terminals | Bidirectional signal paths; interchangeable with COMx pins for flexible mux/switch topology design. |
| COM0–COM7 (Pins 6,8,10,12,13,15,17,19) | Common analog terminals | Each pairs with corresponding NOx to form independent SPST switches; no internal connection between COMs. |
| V− (Pin 21) | Negative analog supply | Sets lower analog voltage limit; connect to GND for single-supply operation (+2.7V to +16V). |
| DOUT (Pin 22) | Serial data output | Shift-register output delayed by 8 clocks; enables daisy-chaining multiple MAX395EAG.TG071 devices. |
| RESET (Pin 23) | Asynchronous reset input | Active-low signal that forces all switches OFF and clears shift register-no clock or CS dependency. |
| CS (Pin 24) | Chip-select input | Active-low enable for serial loading; rising edge latches 8-bit data into switch control register. |
Key Features
| Feature | Design Value |
|---|---|
| 8 independently controllable SPST switches | Enables flexible reconfiguration as 8:1 mux, dual 4:2 differential mux, or quad SPDT using external wiring. |
| Rail-to-rail analog signal handling | Supports input signals spanning full V− to V+ range-eliminates level-shifting in ±5V, ±3V, or +5V systems. |
| Daisy-chainable serial interface | DOUT output allows cascading multiple MAX395EAG.TG071 units with shared SCLK/CS/DIN-reduces MCU GPIO count. |
| Asynchronous hardware RESET | Guarantees known OFF state at power-up or fault recovery-critical for safety-critical analog signal path control. |
| TTL/CMOS logic compatibility | 0.8V–2.4V input thresholds ensure reliable interfacing with both 3.3V and 5V microcontrollers without level shifters. |
| 2kV ESD protection (HBM) | Robust handling of electrostatic discharge during board assembly and field operation-reduces test yield loss. |
Applications
| Industrial Process Monitoring | Avionics Signal Routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX391CNG+ | Quad SPST switch (4 channels), same serial interface and pinout per quadrant; requires two devices for 8-channel coverage. | Limited to 4-channel configurations unless paralleled; lacks integrated 8-bit shift register-requires external logic for full control. | Select when board space permits discrete quad implementation or when partial channel control suffices. |
| ADG708BRUZ | 8-channel CMOS SPST switch with parallel (not serial) 3-wire control; 4Ω typical RON, but no daisy-chain or RESET pin. | Requires 3 dedicated GPIOs (ADDR0–2 + EN) instead of 4 serial lines; no hardware reset-relies on software initialization. | Prefer for low-RON priority in non-daisy-chain systems where microcontroller GPIOs are abundant and reset reliability is software-managed. |
Compared with MAX395EAG.TG071, MAX391CNG+ offers modularity but increases component count and layout complexity for 8-channel use, while ADG708BRUZ trades serial simplicity and hardware reset for lower on-resistance and parallel control overhead.

FAQ
What supply voltages does the MAX395EAG.TG071 support?
The MAX395EAG.TG071 supports dual supplies from ±2.7V to ±8V or a single supply from +2.7V to +16V. When using single-supply operation, V− must be tied to GND. The device maintains rail-to-rail analog signal handling across all supported supply configurations, and logic inputs remain compatible with TTL/CMOS levels at +5V or ±5V supplies.
How does the serial interface of the MAX395EAG.TG071 work?
The MAX395EAG.TG071 uses a 3-wire SPI™/QSPI™/Microwire™-compatible interface: DIN accepts an 8-bit control word (D7–D0), SCLK clocks data on its rising edge, and CS rising edge latches the data to update all eight switches. DOUT provides daisy-chain capability by outputting the shifted-out bit after eight clocks. RESET provides asynchronous initialization independent of clock or CS state.
Can the MAX395EAG.TG071 be used as a multiplexer?
Yes-the MAX395EAG.TG071 can be configured as an 8:1 multiplexer by connecting COM0–COM7 together as the output and using NO0–NO7 as inputs. It also supports dual 4:2 differential mux and quad SPDT topologies via external pin wiring. Its 100Ω RON, ≤5Ω matching, and <−90dB crosstalk make it suitable for precision multiplexing in data-acquisition systems.
What is the purpose of the RESET pin on the MAX395EAG.TG071?
The RESET pin on the MAX395EAG.TG071 is an active-low asynchronous input that forces all eight switches to the OFF state and clears the internal 8-bit shift register to zero-regardless of SCLK or CS state. This guarantees a known, safe analog signal path at power-up or during fault recovery, eliminating reliance on proper initialization sequence timing.
Does the MAX395EAG.TG071 support daisy-chaining with other devices?
Yes-the MAX395EAG.TG071 supports daisy-chaining via its DOUT pin, which outputs the serial data stream delayed by eight clock cycles. Multiple MAX395EAG.TG071 devices can share SCLK, CS, and DIN lines, with DOUT of one connected to DIN of the next. A single CS pulse updates all devices simultaneously, enabling scalable channel expansion without additional control lines.
