Product details
Overview
MAX4642EUA+TG104 from Maxim Integrated is a dual, single-pole/single-throw (SPST), normally closed (NC) CMOS analog switch operating from a single +1.8V to +5.5V supply. It delivers 4Ω max on-resistance at +5V, 0.6Ω max RON matching between channels, and 1Ω max RON flatness, enabling precision signal routing in low-voltage battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4642EUA+TG104 datasheet, MAX4642EUA+TG104 pinout, MAX4642EUA+TG104 application, or MAX4642EUA+TG104 equivalent, key selection criteria include guaranteed RON specs across temperature, sub-20ns switching times, rail-to-rail analog signal handling, and ultra-low 0.35nA leakage over –40°C to +85°C.
Technical Context
The MAX4642EUA+TG104 implements two independent NC switches with complementary control logic: IN1 and IN2 directly drive NC1 and NC2, respectively, closing the path when logic low. Its CMOS architecture supports bidirectional analog signal flow with matched channel characteristics, and internal ESD diodes clamp analog pins to V+ and GND for ±0.3V overvoltage tolerance.
It features guaranteed dynamic performance: tON ≤ 15ns and tOFF ≤ 8ns at +5V, –80dB off-isolation and –97dB crosstalk at 1MHz, and 0.018% THD with 600Ω load - all specified over full industrial temperature range without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct interface with Li-ion, 3.3V, and 5V logic without level shifters |
| RON (max, +5V) | 4Ω - ensures minimal signal attenuation and voltage drop in precision sensor or audio paths |
| RON Matching (max) | 0.6Ω - guarantees matched gain/attenuation in differential or dual-channel routing applications |
| RON Flatness (max) | 1Ω - maintains consistent channel impedance across full 0V to V+ analog swing |
| tON/tOFF (typ) | 18ns/12ns - supports high-speed multiplexing in sampling systems up to ~25MHz effective rate |
| Leakage Current (max) | ±0.35nA over –40°C to +85°C - preserves accuracy in high-impedance sensor front-ends and sample-and-hold circuits |
| Off-Isolation @ 1MHz | –80dB - suppresses coupling between inactive channels in multi-signal routing |
Pinout & Package
MAX4642EUA+TG104 is housed in an 8-pin µMAX package (3mm × 3mm, 0.8mm height), pin-compatible with industry-standard SOIC-8 footprints but with 50% smaller area. The package uses exposed pad for thermal enhancement and requires standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | NC1, NC2 | Normally closed analog terminals - conduct to COMx when respective INx is low; bidirectional signal path |
| 2, 6 | IN1, IN2 | Digital control inputs - active-low logic; TTL/CMOS compatible only at +5V supply |
| 3, 7 | GND | Analog and digital ground reference - must be low-impedance; bypass V+ to GND with 0.1µF ceramic capacitor |
| 4 | COM1 | Common terminal for first NC switch - connects to NC1 when IN1 = low |
| 8 | V+ | Positive supply input - powers analog switch core and internal logic; decoupling mandatory |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports full 0V to V+ signal swing without clipping - essential for unipolar sensor outputs and DAC buffers |
| Guaranteed RON flatness | 1Ω max variation across entire analog range - eliminates harmonic distortion in AC-coupled audio paths |
| Low charge injection | 2pC typical - minimizes voltage glitch during switching in sample-and-hold and ADC front-end designs |
| Ultra-low quiescent power | <0.01µW - extends battery life in always-on portable instrumentation and wearables |
| High off-isolation & low crosstalk | –80dB off-isolation and –97dB crosstalk at 1MHz - enables clean multi-channel signal routing in dense PCB layouts |

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 |
|---|---|---|---|
| MAX4642EUA+ | No tape-and-reel packaging; same µMAX-8 package, identical electrical specs, and pinout as MAX4642EUA+TG104 | Identical functional use; suited for prototype and low-volume hand-soldered builds | Select MAX4642EUA+TG104 for automated SMT production requiring 1000-unit tape-and-reel delivery. |
| ADG722BRMZ-REEL7 | Higher 6.5Ω RON at +5V; 10ns tON/8ns tOFF; operates down to +1.8V but specifies only 0.5nA leakage (not guaranteed over full temp range) | Acceptable for less demanding signal integrity requirements; lacks guaranteed RON matching and flatness specs | Choose ADG722BRMZ-REEL7 only if cost sensitivity outweighs need for guaranteed matching and leakage performance. |
Compared with MAX4642EUA+ and ADG722BRMZ-REEL7, MAX4642EUA+TG104 uniquely provides factory-guaranteed 0.6Ω RON matching and 0.35nA leakage over –40°C to +85°C - critical for production-grade medical and test equipment where parameter consistency across units and temperature is non-negotiable.

FAQ
What is the maximum guaranteed on-resistance for MAX4642EUA+TG104 at +5V supply?
The MAX4642EUA+TG104 guarantees a maximum on-resistance (RON) of 4Ω when operated with a +5V supply, measured under conditions of VCOM = 1V or 4.5V and ICOM = 10mA across the full –40°C to +85°C temperature range. This specification ensures predictable voltage drop and minimal signal attenuation in precision analog paths, and is explicitly validated per Maxim's datasheet Table 1.
Does MAX4642EUA+TG104 support rail-to-rail analog signal operation?
Yes, MAX4642EUA+TG104 supports rail-to-rail analog signal operation - its analog terminals (NC1, NC2, COM1, COM2) handle signals from 0V to V+ continuously, with guaranteed RON flatness of 1Ω max over that full range at +5V. This capability is intrinsic to its CMOS process design and confirmed in both the General Description and Electrical Characteristics sections of the official datasheet.
What is the leakage current specification for MAX4642EUA+TG104 over temperature?
MAX4642EUA+TG104 guarantees a maximum leakage current of ±0.35nA for all analog terminals (NC_, COM_) over the full industrial temperature range of –40°C to +85°C. This value is tested and specified in the datasheet's Electrical Characteristics tables for both COM_ on-leakage and NO_/NC_ off-leakage, making it suitable for high-impedance sensor interfaces and sample-and-hold applications where leakage-induced error must be minimized.
Is MAX4642EUA+TG104 pin-compatible with other packages in the MAX464x family?
Yes, MAX4642EUA+TG104 in the 8-pin µMAX package shares identical pinout and functionality with MAX4642EGA (8-pin QFN) and MAX4642EUA+ (same µMAX, non-tape-and-reel). All three variants use the same pin numbering, terminal functions, and logic behavior - enabling direct PCB layout reuse when migrating between µMAX and QFN for thermal or assembly requirements.
What switching speed does MAX4642EUA+TG104 achieve at +3V supply?
At +3V supply, MAX4642EUA+TG104 achieves a typical turn-on time (tON) of 22ns and turn-off time (tOFF) of 11ns, with maximum values of 20ns and 10ns respectively over temperature. These values are documented in the +3V Electrical Characteristics table and reflect its optimized low-voltage switching performance - critical for energy-efficient portable systems operating from single-cell lithium or regulated 3.3V rails.
