Product details
Overview
MAX4642EUA+G104 from Maxim Integrated is a dual, single-pole/single-throw (SPST) analog switch with two normally closed (NC) channels, operating from +1.8V to +5.5V single supply. It delivers 4Ω max on-resistance at +5V, 0.6Ω max RON matching between channels, and 1Ω max RON flatness over full signal range. Designed for low-leakage, high-speed signal routing in battery-powered instrumentation and audio systems.
For engineers reviewing the MAX4642EUA+G104 datasheet, MAX4642EUA+G104 pinout, MAX4642EUA+G104 application, or MAX4642EUA+G104 equivalent, key selection criteria include guaranteed RON specs across voltage/temperature, rail-to-rail analog signal handling, sub-20ns switching, <0.35nA leakage, and µMAX-8 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4642EUA+G104 implements CMOS transmission-gate architecture with integrated logic-level translators, enabling TTL/CMOS-compatible control inputs only at +5V supply while maintaining functional operation down to +1.8V. Its bidirectional analog path supports rail-to-rail signal swing without external biasing.
Each NC channel features matched on-resistance characteristics and tightly controlled dynamic parameters: tON = 18ns typ / 22ns max, tOFF = 12ns typ / 14ns max at +5V, with -97dB crosstalk and -80dB off-isolation at 1MHz. Charge injection is limited to 2pC, ensuring minimal settling error in precision sampling circuits.
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 domains without level shifters. |
| On-Resistance (RON) | 4Ω max at +5V, 8Ω max at +3V - ensures minimal signal attenuation and gain error in sensor/ADC front-ends. |
| RON Matching | 0.6Ω max between channels at +5V - critical for differential signal integrity and matched-path applications. |
| Leakage Current | <0.35nA over -40°C to +85°C - preserves accuracy in high-impedance measurement paths and battery-monitoring circuits. |
| Switching Speed | tON = 18ns typ, tOFF = 12ns typ at +5V - supports multiplexing of audio, video, and fast data-acquisition signals. |
| Analog Signal Range | Rail-to-rail - allows full-swing AC/DC signals from GND to V+ without clipping or distortion. |
| Total Harmonic Distortion | 0.018% at 20Hz–20kHz - maintains fidelity in audio routing and low-noise instrumentation. |
Pinout & Package
MAX4642EUA+G104 is housed in an 8-pin µMAX package (3mm × 3mm, 0.8mm height), compatible with standard SO-8 footprints but offering 50% smaller area and improved thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | NC1, NC2 | Normally closed analog terminals - conduct when INx = LOW; open when INx = HIGH; bidirectional signal path. |
| 2, 6 | IN1, IN2 | Digital control inputs - TTL/CMOS-compatible at +5V; logic thresholds scale with V+ (VIL = 0.8V typ, VIH = 2.4V typ at +5V). |
| 3, 7 | GND | Ground reference for analog and digital sections - must be low-impedance connection to minimize noise coupling. |
| 4 | COM1 | Common terminal for first NC switch - connects to NC1 when IN1 = LOW; isolated when IN1 = HIGH. |
| 8 | V+ | Positive supply input - requires local 0.1µF ceramic bypass capacitor to GND for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full-swing signals from GND to V+, eliminating need for external bias networks in AC-coupled systems. |
| Guaranteed RON flatness (1Ω) | Maintains consistent gain and linearity across entire analog input range - essential for precision data acquisition. |
| Low charge injection (2pC) | Minimizes voltage glitch during switching - reduces settling time and error in sample-and-hold and ADC multiplexing. |
| High off-isolation (-80dB @ 1MHz) | Prevents signal bleed-through between inactive channels - critical for multi-channel audio/video routing. |
| Ultra-low quiescent power (<0.01µW) | Enables always-on signal path control in energy-sensitive portable devices without measurable battery drain. |

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+ | Same die, identical electrical specs, same µMAX-8 package - differs only in tape-and-reel packaging (G104 denotes 1000-piece reel). | No functional difference; suitable for identical use cases including medical sensors and audio routing. | Select MAX4642EUA+G104 for volume production requiring standardized reel delivery; MAX4642EUA+ for sample evaluation or small-batch prototyping. |
| ADG722BRMZ-REEL7 | 2.5Ω RON max at +5V, but higher 1nA leakage and no guaranteed RON flatness spec; uses MSOP-8 package (3.0mm × 4.9mm). | Acceptable for lower-precision audio or general-purpose muxing where leakage <1nA is tolerable. | Choose ADG722BRMZ-REEL7 only if board layout accommodates larger MSOP footprint and system tolerates higher leakage-induced offset drift. |
Compared with MAX4642EUA+G104, the MAX4642EUA+ offers identical performance in a different packaging format, while the ADG722BRMZ-REEL7 trades guaranteed flatness and ultra-low leakage for marginally lower RON - making MAX4642EUA+G104 optimal for precision, low-power, and space-constrained designs.

FAQ
What is the maximum supply voltage rating for MAX4642EUA+G104?
The absolute maximum supply voltage for MAX4642EUA+G104 is +6V, but operational specifications are guaranteed only from +1.8V to +5.5V. Exceeding +5.5V risks permanent damage and voids parametric guarantees; sustained operation above +5.5V violates Absolute Maximum Ratings and may degrade long-term reliability.
Does MAX4642EUA+G104 support rail-to-rail analog signals?
Yes, MAX4642EUA+G104 supports rail-to-rail analog signal ranges - meaning signals from GND to V+ pass through the NC switches without clipping or distortion. This capability is confirmed in the datasheet's "Rail-to-Rail™ Analog Signal Range" feature and Electrical Characteristics table under "Analog Signal Range."
What is the typical on-resistance matching between channels for MAX4642EUA+G104?
The typical on-resistance matching (∆RON) between the two NC channels of MAX4642EUA+G104 is 0.2Ω at +5V, with a guaranteed maximum of 0.6Ω across -40°C to +85°C. This specification ensures consistent gain and phase response in differential or parallel-switched configurations.
Can MAX4642EUA+G104 operate from a 1.8V supply?
Yes, MAX4642EUA+G104 is fully specified for operation from +1.8V to +5.5V. At +1.8V, RON rises to 30Ω typical over temperature, and logic thresholds scale accordingly (VIL ≈ 0.4V, VIH ≈ 2.0V). All timing and leakage specs remain valid per datasheet Conditions tables.
Is MAX4642EUA+G104 pin-compatible with MAX4641EUA+G104?
No, MAX4642EUA+G104 is not pin-compatible with MAX4641EUA+G104 despite identical µMAX-8 packaging and pin count. The MAX4641 has NO (normally open) switches on pins 1/5, while MAX4642 has NC (normally closed) switches on those same pins - requiring PCB layout changes for functional replacement.
