Product details
Overview
MAX4604CPE+ from Maxim Integrated is a quad, single-pole single-throw (SPST), normally closed (NC) analog switch IC with 5Ω max on-resistance, 0.5Ω max RON match between channels, and rail-to-rail signal handling capability across ±4.5V to ±20V dual supplies or +4.5V to +36V single supply. It delivers 2.5nA max off-leakage at +85°C and supports TTL/CMOS-compatible control inputs - ideal for reed relay replacement in automated test equipment.
For engineers reviewing the MAX4604CPE+ datasheet, MAX4604CPE+ pinout, MAX4604CPE+ application, or MAX4604CPE+ equivalent, key selection criteria include guaranteed RON flatness (0.5Ω max), low charge injection (225pC typ), dual-/single-supply flexibility, and 16-pin PDIP package compatibility with legacy through-hole layouts.
Technical Context
The MAX4604CPE+ implements four independent CMOS SPST switches configured as normally closed (NC), each with matched on-resistance and flat RON over its full analog signal range (±10V with ±15V supplies). Its logic inputs feature fixed 0.8V/2.4V thresholds, enabling direct interface with TTL/CMOS without level-shifting when operating from ±15V or +12V supplies.
Internal protection diodes clamp signals exceeding V+ or V−, limiting forward current per Absolute Maximum Ratings. The device supports rail-to-rail analog operation, exhibits 34pF COM off-capacitance and 100pF COM on-capacitance (single supply), and achieves 120ns turn-on / 130ns turn-off times under standard 50Ω/5pF load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 5Ω max - ensures minimal voltage drop and signal attenuation in precision analog paths |
| RON Match | 0.5Ω max - enables accurate channel-to-channel signal routing without gain mismatch |
| RON Flatness | 0.5Ω max over ±10V - maintains consistent insertion loss across full input signal swing |
| Off-Leakage Current | 2.5nA max at +85°C - preserves high-impedance node integrity in sensor/mux applications |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports industrial and mixed-signal systems |
| Logic Thresholds | 0.8V low / 2.4V high - guarantees reliable TTL/CMOS compatibility without external biasing |
| Turn-On/Off Time | 120ns / 130ns (typ, RL=50Ω, CL=5pF) - suitable for moderate-speed multiplexing up to ~1MHz |
Pinout & Package
MAX4604CPE+ uses a 16-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Pin spacing is 0.1 inch; lead finish is matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs - active-low logic drives NC switches open (disconnect) |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connect to signal source or load in SPST configuration |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - conduct to COM when IN = 0V; open when IN ≥ 2.4V |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation (+4.5V to +36V) |
| 5 | GND | Digital/analog ground reference - shared return for logic and analog sections |
| 12 | VL | Logic supply input - accepts 2.7V to 5.5V; decouples logic threshold stability from analog rails |
| 13 | V+ | Positive analog supply - sets upper rail for rail-to-rail analog signal range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full-swing signals from V− to V+ - eliminates clipping in ±15V op-amp or DAC interfaces |
| Guaranteed RON match (0.5Ω max) | Enables precise multi-channel gain matching in programmable-gain amplifiers or sensor arrays |
| TTL/CMOS-compatible logic inputs | Eliminates need for level translators when interfacing with microcontrollers or FPGAs using +5V or ±15V supplies |
| ESD protection >2000V (HBM) | Reduces risk of field failure during board handling and system integration without external protection |
| Low charge injection (225pC typ) | Minimizes transient glitches in sample-and-hold or switched-capacitor circuits |
Applications
| Reed Relay Replacement | Test Equipment Signal Routing |
|---|---|
|
Use Scenario: Replacing electromechanical relays in automated test fixtures where cycle life, speed, and size are critical. IC Role / Device Role / Timing Role: Quad SPST NC switch providing solid-state isolation and connection control for DUT signal paths. Use Value: 100M+ switching cycles vs. <1M for relays, 120ns switching vs. 10ms relay settling, and 16-pin DIP footprint replacing 4× relay modules. |
Use Scenario: Multiplexing stimulus and response signals among multiple instruments and devices under test. IC Role / Device Role / Timing Role: Low-RON, matched analog switch enabling calibrated signal path selection without gain error. Use Value: 0.5Ω RON match ensures ≤0.01% channel-to-channel gain variation; rail-to-rail support covers full instrument output range. |
| Avionics Signal Conditioning | Audio-Signal Routing |
|
Use Scenario: Selecting sensor inputs (e.g., temperature, pressure) in flight data acquisition units with strict reliability requirements. IC Role / Device Role / Timing Role: NC-configured analog switch ensuring default-closed safety path during power-up or fault conditions. Use Value: 2.5nA max off-leakage prevents DC drift in high-Z sensor bridges; -40°C to +85°C grade (E-grade variants) meets DO-160 thermal specs. |
Use Scenario: Channel selection and mute control in professional audio mixers and effects processors. IC Role / Device Role / Timing Role: Low-distortion analog switch routing line-level or headphone signals with minimal THD. Use Value: 5Ω RON and flat RON reduce frequency-dependent insertion loss; low charge injection avoids audible pop/click on mute transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4604EPE+ | Same functionality and pinout, but rated for -40°C to +85°C industrial temperature range | Suitable for extended-temperature environments where MAX4604CPE+ (0°C to +70°C) may fail | Select MAX4604EPE+ when operating outside commercial temperature limits; otherwise MAX4604CPE+ suffices |
| ADG444BRZ | Quad SPST NO switch (not NC); 4.5Ω RON; requires separate VDD/VSS for ±15V operation; no VL pin | Requires redesign of control logic polarity and power sequencing; lacks dedicated logic supply | Use only if NO configuration is acceptable and VL decoupling is not required for logic threshold stability |
Compared with MAX4604CPE+, MAX4604EPE+ offers identical performance with extended temperature range, while ADG444BRZ provides similar RON but demands NO-based logic inversion and lacks VL pin flexibility - making MAX4604CPE+ preferable for NC-critical, temperature-stable, and logic-supply-isolated designs.

FAQ
What is the maximum supply voltage rating for MAX4604CPE+?
The MAX4604CPE+ supports absolute maximum analog supply ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V. For continuous operation, use +4.5V to +36V single supply or ±4.5V to ±20V dual supply. Exceeding these limits risks permanent damage due to internal diode clamping and forward-current stress.
Does MAX4604CPE+ support rail-to-rail analog signal operation?
Yes, MAX4604CPE+ supports true rail-to-rail analog signal handling - signals from V− to V+ pass unattenuated through the switch when ON. This is confirmed in the General Description and Electrical Characteristics tables, where input voltage range is specified as (V− − 0.3V) to (V+ + 0.3V) with internal clamping diodes.
What is the logic configuration of MAX4604CPE+ switches?
MAX4604CPE+ contains four normally closed (NC) SPST analog switches. When logic input (INx) is low (≤0.8V), the corresponding COM–NC path is closed (low RON). When INx is high (≥2.4V), the path opens. This behavior is explicitly defined in the General Description and verified in the MAX4604 pin configuration diagram.
Can MAX4604CPE+ operate from a single +5V supply?
No - the minimum single-supply voltage for MAX4604CPE+ is +4.5V. At +5V, it operates within specification, but logic thresholds (0.8V/2.4V) and RON performance remain valid only when VL = 5V and V+ ≥ 4.5V. Operation below 4.5V violates the Absolute Maximum Ratings and is not characterized.
Is MAX4604CPE+ pin-compatible with MAX4605CPE+ or MAX4606CPE+?
Yes - all three variants (MAX4604/MAX4605/MAX4606) share identical 16-pin PDIP pinouts and package dimensions. However, their switch configurations differ: MAX4604CPE+ is NC-only, MAX4605CPE+ is NO-only, and MAX4606CPE+ combines two NC and two NO switches. PCB layout is interchangeable, but firmware/control logic must match the switch type.
