Product details
Overview
MAX4609ESE 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 maximum on-resistance, rail-to-rail signal handling (±15V dual or +12V single supply), and guaranteed RON match ≤0.5Ω between channels. It serves as a solid-state replacement for reed relays in automated test equipment requiring low distortion and high reliability.
For engineers reviewing the MAX4609ESE datasheet, MAX4609ESE pinout, MAX4609ESE application, or MAX4609ESE equivalent, key selection criteria include its dual-supply compatibility (±4.5V to ±20V), TTL/CMOS-compatible logic thresholds (+0.8V / +2.4V), sub-150ns switching times, <2.5nA off-leakage at +85°C, and 16-pin narrow SO package with validated NC/NO/COM terminal mapping.
Technical Context
The MAX4609ESE integrates two independent SPST switches fabricated in BiCMOS process, each with matched and flat on-resistance over full signal range (–15V to +15V). Its control architecture uses separate digital inputs (IN1, IN2) with fixed logic polarity: IN1 controls COM1–NC1 (active-low) and COM1–NO1 (active-high); IN2 controls COM2–NC2 and COM2–NO2 identically.
It supports both single-supply (+4.5V to +36V) and dual-supply (±4.5V to ±20V) operation, with VL pin enabling independent logic-level referencing. ESD protection exceeds 2kV per MIL-STD-3015.7, and leakage currents are fully tested at –40°C to +85°C temperature extremes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max at ±15V dual supply - ensures minimal voltage drop and power loss in precision signal routing paths |
| RON Match Between Channels | 0.5Ω max - enables accurate differential or ratiometric measurements without calibration offset |
| RON Flatness | 0.5Ω max over full signal range - maintains consistent gain and linearity across rail-to-rail analog inputs |
| Off-Leakage Current | 2.5nA max at +85°C - preserves high-impedance node integrity in sensor front-ends and sample-hold circuits |
| Turn-On / Turn-Off Time | 110ns / 150ns typical at VCOM = ±10V - supports >5MHz multiplexing in data acquisition systems |
| Supply Range | ±4.5V to ±20V dual or +4.5V to +36V single - accommodates industrial ±15V and automotive +12V/24V rails |
| Logic Thresholds | +0.8V low / +2.4V high - guarantees direct interface with standard TTL and CMOS microcontrollers |
Pinout & Package
MAX4609ESE is housed in a 16-pin narrow SO (Small Outline) package, RoHS-compliant, with 1.27mm pitch and JEDEC MS-012AC outline (S16-8). Thermal resistance θJA = 115°C/W; rated for –40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connection (N.C.) | Unbonded die pads; must be connected to GND for optimal off-isolation and noise immunity |
| 2, 7 | IN1, IN2 | Digital control inputs - active-high drives NO path, active-low drives NC path per switch |
| 4 | V− | Negative analog supply - connect to DGND for single-supply operation |
| 5 | GND | Analog/digital ground reference - star-point connection recommended for mixed-signal layouts |
| 9, 16 | NO1, NO2 | Normally open analog terminals - conduct only when respective INx = high |
| 11, 14 | COM1, COM2 | Common analog I/O nodes - bidirectional, rail-to-rail capable, ±100mA continuous current rating |
| 12 | VL | Logic supply reference - decouples logic threshold from analog rails; tie to +5V or system logic VCC |
| 13 | V+ | Positive analog supply - sets upper signal limit; supports up to +36V in single-supply mode |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance | 2.5Ω max ensures <0.1% gain error in 10kΩ load applications and minimal THD in audio routing |
| Rail-to-rail signal handling | Supports full swing from V− to V+ - eliminates level-shifting in ±15V op-amp signal chains |
| Guaranteed RON match & flatness | ≤0.5Ω variation enables matched-channel applications like differential ADC input switching without trimming |
| TTL/CMOS-compatible inputs | +0.8V/+2.4V thresholds allow direct drive from 3.3V or 5V microcontrollers without level shifters |
| ESD protection | >2kV HBM - reduces need for external TVS diodes in board-level ESD design |

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 |
|---|---|---|---|
| ADG1419BRUZ | 4.7Ω RON, ±15V only, no VL pin, 16-TSSOP | Higher on-resistance limits use in <10kΩ precision paths; lacks logic supply independence | Select when lower cost and ADI ecosystem integration outweigh RON and flexibility needs |
| TS5A3159DCKR | 0.75Ω RON, +1.65V to +5.5V only, 6-pin SC70 | Single-supply only; unsuitable for ±15V industrial or avionics rails | Choose for battery-powered, low-voltage portable instruments where ultra-low RON is critical |
Compared with ADG1419BRUZ and TS5A3159DCKR, MAX4609ESE uniquely balances wide supply range (±4.5V to ±20V), low 2.5Ω RON, matched channels, and logic-level flexibility via VL-making it the only option qualified for high-reliability, multi-rail industrial and aerospace signal routing.

FAQ
What is the maximum supply voltage rating for MAX4609ESE?
The MAX4609ESE supports dual supplies from ±4.5V to ±20V and single supplies from +4.5V to +36V. Absolute maximum ratings specify V+ to GND ≤ +44V and V− to GND ≥ –44V, with V+ to V− differential ≤ +44V. Exceeding these may cause permanent damage, and operation beyond specified ranges is not guaranteed.
Does MAX4609ESE support rail-to-rail analog signal switching?
Yes, MAX4609ESE supports true rail-to-rail analog signal handling: input signals can swing from V− to V+, including ±15V dual-supply and +12V single-supply configurations. This capability is confirmed in the Electrical Characteristics tables and Typical Operating Characteristics plots (e.g., Figure MAX4607/08/09-01).
How is the logic polarity defined for the two switches in MAX4609ESE?
In MAX4609ESE, IN1 controls COM1: low logic selects NC1, high logic selects NO1; IN2 controls COM2 identically. This is explicitly shown in the truth table and pin-function table (page 7 of datasheet), where "0" = OFF for NO and ON for NC, and "1" = ON for NO and OFF for NC.
What is the purpose of the VL pin on MAX4609ESE?
The VL pin on MAX4609ESE sets the reference voltage for internal logic threshold comparators, enabling independent logic-level interfacing (e.g., +3.3V or +5V) while operating from high analog supplies (e.g., ±15V). It decouples digital control from analog rail constraints and is required for proper TTL/CMOS compatibility across all supply configurations.
Is MAX4609ESE pin-compatible with MAX4607ESE or MAX4608ESE?
Yes, MAX4609ESE shares identical pinout, package (16-pin narrow SO), and footprint with MAX4607ESE and MAX4608ESE. The only functional difference is switch configuration: MAX4607ESE has two NC switches, MAX4608ESE has two NO switches, and MAX4609ESE has one NC and one NO switch-enabling drop-in replacement where topology permits.
