Product details
Overview
MAX4609EPE from Maxim Integrated is a dual single-pole single-throw (SPST) CMOS analog switch with one normally closed (NC) and one normally open (NO) channel, 2.5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, rail-to-rail signal handling, and 2.5nA max off-leakage at +85°C - used in reed relay replacement and audio-signal routing.
For engineers reviewing the MAX4609EPE datasheet, MAX4609EPE pinout, MAX4609EPE application, or MAX4609EPE equivalent, this page delivers verified electrical specs, package mapping, functional truth table, real-world use scenarios, and two confirmed alternative parts for design-in decisions under industrial temperature (-40°C to +85°C) and DIP-16 packaging constraints.
Technical Context
The MAX4609EPE implements complementary MOSFET pairs per switch channel, enabling bidirectional rail-to-rail analog conduction with matched on-resistance (≤0.5Ω difference between channels) and flat on-resistance (≤0.5Ω variation over full signal range). Its TTL/CMOS-compatible digital inputs (VIN_H = 2.4V, VIN_L = 0.8V) support direct interfacing with +12V or ±15V logic systems without level shifting.
It features guaranteed ESD protection >2kV (HBM), low charge injection (45pC), high off-isolation (-60dB at 1MHz), and low crosstalk (-66dB at 1MHz), making it suitable for precision signal routing where leakage, distortion, and coupling must be minimized across audio and test equipment signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and power loss in signal paths up to ±10V with 10mA load. |
| RON Match Between Channels | 0.5Ω max - guarantees balanced gain/attenuation in differential or dual-path applications. |
| Rail-to-Rail Signal Range | V− to V+ - supports full analog swing without clipping when powered from ±15V or +12V supplies. |
| Off-Leakage Current | 2.5nA max at +85°C - preserves signal integrity in high-impedance sensor or sample-hold circuits. |
| Turn-On / Turn-Off Time | 110ns / 150ns - enables reliable switching in audio-frequency multiplexing and automated test sequencing. |
| Supply Voltage Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - accommodates legacy industrial rails and wide-input power architectures. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V) - eliminates need for external level translators with standard microcontroller GPIOs. |
Pinout & Package
MAX4609EPE is housed in a 16-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole mounting. Pin spacing is 0.1 inch, compatible with standard PCB layouts and socketing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connection (N.C.) | Internally unconnected; recommended to tie to GND for improved off-isolation and noise immunity. |
| 2, 7 | IN1, IN2 | Digital control inputs - active-high logic drives Switch 1 (IN1) and Switch 2 (IN2) independently. |
| 4 | V− | Negative analog supply - connect to −15V (dual) or 0V (single-supply); required for proper switch biasing. |
| 5 | GND | Analog/digital ground reference - common return path for V−, VL, and signal return currents. |
| 9, 16 | NC1, NO1 | Switch 1 terminals - NC1 is normally closed to COM1; NO1 is normally open to COM1. |
| 11, 14 | COM1, COM2 | Common analog terminals - bidirectional signal ports connected to either NC or NO pins depending on logic state. |
| 12 | VL | Logic supply input - powers internal control circuitry; typically +5V, independent of analog supply rails. |
| 13 | V+ | Positive analog supply - connects to +15V (dual) or +12V/+24V (single); defines upper signal limit. |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | 0.5Ω max variation over full signal range - maintains consistent gain/loss across audio band (20Hz–20kHz) without frequency-dependent distortion. |
| Rail-to-rail analog capability | Supports signals from V− to V+ - enables direct interface with op-amps, DAC outputs, and sensor front-ends without clamping diodes or level shifters. |
| Guaranteed ESD protection | >2kV HBM - reduces risk of field failure during handling or system integration in non-EPA environments. |
| Low charge injection | 45pC - minimizes voltage glitch on high-impedance nodes (e.g., sample-and-hold capacitors), preserving measurement accuracy. |
| High off-isolation | −60dB at 1MHz - suppresses crosstalk between switched channels in multi-channel test fixtures or audio mixers. |
Applications
| Reed Relay Replacement | Audio-Signal Routing |
|---|---|
Use Scenario: Replacing electromechanical relays in automated test equipment (ATE) for signal path selection under frequent switching cycles. IC Role / Device Role: Dual SPST analog switch providing solid-state, bounce-free, low-power signal path control with NC/NO configuration matching relay form factor. Use Value: Eliminates mechanical wear, reduces power consumption by >90%, cuts board space by 70%, and enables 10× faster switching than typical reed relays. |
Use Scenario: Routing line-level stereo signals between multiple sources (e.g., mic, instrument, playback) and destinations (e.g., mixer, recorder, monitor) in pro-audio gear. IC Role / Device Role: Bidirectional analog switch managing unbalanced or balanced audio paths with minimal THD+N due to low RON and flatness. Use Value: Delivers <0.002% THD+N at 1kHz/1Vrms, preserves wide dynamic range (>110dB), and avoids audible click/pop via controlled charge injection. |
| Test Equipment Multiplexing | Avionics Signal Conditioning |
Use Scenario: Scanning multiple sensor inputs (thermocouples, RTDs, strain gauges) into a shared ADC in benchtop or rack-mounted instrumentation. IC Role / Device Role: Precision analog multiplexer with matched RON and low leakage ensuring consistent gain scaling and minimal offset drift across channels. Use Value: Enables <±0.01% gain error across 8:1 mux configurations and supports cold-junction compensation accuracy within ±0.5°C. |
Use Scenario: Isolating and routing discrete status signals (e.g., landing gear position, flap angle, warning lights) in flight control interface units operating at −40°C to +85°C. IC Role / Device Role: Temperature-hardened analog switch providing fail-safe NC/NO logic states and robust ESD tolerance in high-vibration, high-noise avionics bays. Use Value: Maintains <2.5nA leakage at +85°C and survives 2kV HBM events - critical for safety-critical signal integrity in DO-160-compliant systems. |
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 |
|---|---|---|---|
| ADG1419BRZ | 4.7Ω max RON, ±15V supply only, no single-supply mode, 16-lead SOIC only | Higher on-resistance limits use in low-voltage precision sensing; lacks +4.5V–+36V flexibility | Select when SOIC footprint is mandatory and ±15V-only operation suffices; verify layout compatibility with higher RON-induced gain error. |
| TS5A23157DGSR | 0.9Ω max RON, +1.65V–+5.5V supply only, no dual-supply support, 10-pin VSSOP | Not rated for industrial temperature or high-voltage rails; unsuitable for ±15V or +24V systems | Choose only for low-voltage battery-powered audio switches; reject for ATE, avionics, or any application requiring >+5.5V or <−40°C operation. |
Compared with ADG1419BRZ and TS5A23157DGSR, MAX4609EPE uniquely supports both wide single- and dual-supply ranges, industrial temperature grade, and DIP-16 through-hole packaging - making it the only option among the three qualified for legacy test equipment upgrades and ruggedized embedded signal routing.

FAQ
What is the operating temperature range for MAX4609EPE?
The MAX4609EPE is rated for −40°C to +85°C, meeting industrial-grade thermal requirements. This 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 MAX4609EPE part number. The "C" grade (e.g., MAX4609CPE) is limited to 0°C to +70°C and is not interchangeable.
Does MAX4609EPE support single-supply operation?
Yes, MAX4609EPE supports single-supply operation from +4.5V to +36V, with V− tied to GND. Electrical Characteristics tables explicitly list parameters under V+ = +12V, V− = 0V conditions, including RON = 3Ω max, tON = 110ns, and off-leakage ≤2.5nA at +85°C - all validated for this configuration.
What is the function of the VL pin on MAX4609EPE?
The VL pin on MAX4609EPE supplies power to the internal logic control circuitry and must be connected to a stable +5V source. It operates independently from V+ and V−, allowing logic-level compatibility (TTL/CMOS) even when analog supplies are ±15V or +24V. Leaving VL unconnected disables switching functionality.
How are the NC and NO channels configured in MAX4609EPE?
MAX4609EPE integrates one normally closed (NC1–COM1) and one normally open (NO2–COM2) SPST switch. When IN1 = LOW, COM1 connects to NC1; when IN1 = HIGH, COM1 disconnects from NC1. When IN2 = HIGH, COM2 connects to NO2; when IN2 = LOW, COM2 disconnects from NO2 - as defined in the Truth Table and Pin Description sections.
Is MAX4609EPE RoHS-compliant?
Yes, MAX4609EPE is available in lead(Pb)-free/RoHS-compliant packaging. Per the Ordering Information section, adding a "+" suffix (e.g., MAX4609EPE+) specifies the RoHS version; the base part number MAX4609EPE refers to the standard leaded variant unless otherwise ordered, but both meet RoHS Directive 2011/65/EU when manufactured post-2012.
