Product details
Overview
MAX4609CPE+ 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, rail-to-rail signal handling (±15V dual or +12V single supply), and 2.5nA max off-leakage at +85°C - used in PBX systems, test equipment, and audio-signal routing where low distortion and relay replacement are critical.
For engineers reviewing the MAX4609CPE+ datasheet, MAX4609CPE+ pinout, MAX4609CPE+ application, or MAX4609CPE+ equivalent, key selection criteria include guaranteed RON match (≤0.5Ω), TTL/CMOS-compatible logic thresholds (+0.8V/+2.4V), ±4.5V to ±20V dual-supply operation, and 16-pin PDIP package compatibility with legacy through-hole layouts.
Technical Context
The MAX4609CPE+ implements two independent SPST switches in a single BiCMOS die: Switch 1 is NC (closed when IN1 = LOW), Switch 2 is NO (closed when IN2 = HIGH), enabling complementary signal path control. Its architecture guarantees matched on-resistance (ΔRON ≤ 0.5Ω) and flat RON (≤0.5Ω variation) over the full ±10V signal range, ensuring minimal gain error in precision multiplexing.
It supports both single-supply (+4.5V to +36V) and dual-supply (±4.5V to ±20V) operation with separate VL logic supply input, allowing level-shifting between analog and digital domains. Input logic thresholds are fixed at +0.8V (VIL) and +2.4V (VIH), eliminating external biasing for TTL/CMOS interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max at ±15V dual supply - ensures <0.05% gain error in 50Ω systems and low voltage drop under 100mA load. |
| RON Match Between Channels | 0.5Ω max - enables precise differential signal switching without channel-to-channel gain mismatch. |
| Off-Leakage Current | 2.5nA max at +85°C - preserves signal integrity in high-impedance sensor front-ends and sample-hold circuits. |
| Turn-On / Turn-Off Time | 110ns / 150ns typical at ±15V - supports >5MHz analog multiplexing with minimal settling delay. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - accommodates industrial, test, and avionics rails without external regulation. |
| Logic Compatibility | +0.8V VIL, +2.4V VIH - directly interfaces 3.3V/5V microcontrollers and FPGAs without level shifters. |
| ESD Protection | >2kV per HBM Method 3015.7 - reduces need for external protection in board-level ESD-prone environments. |
Pinout & Package
MAX4609CPE+ uses a 16-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Pin 1 is top-left corner (notch side), pin 16 is top-right. All N.C. pins (1, 3, 6, 8, 10, 15) must be connected to GND for optimal off-isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connection (N.C.) | Internally unconnected; tie to GND to reduce crosstalk and improve off-isolation performance. |
| 2, 7 | IN1, IN2 | Digital control inputs: IN1 controls NC1 (active-low), IN2 controls NO2 (active-high). |
| 4 | V− | Negative analog supply; connect to DGND for single-supply operation. |
| 5 | GND | Analog/digital ground reference; star-point connection recommended for noise-sensitive designs. |
| 9, 16 | NC1, NO1 | Normally closed and normally open terminals for Switch 1 - only one conducts per state. |
| 11, 14 | COM1, COM2 | Common analog terminals - bidirectional signal paths with rail-to-rail voltage support. |
| 12 | VL | Logic supply input - accepts +2.7V to +5.5V to set logic threshold independently of analog rails. |
| 13 | V+ | Positive analog supply - defines upper signal limit and powers internal switch driver circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ (e.g., −15V to +15V), enabling direct interface with op-amp outputs and sensor bridges without clamping. |
| Guaranteed RON flatness (≤0.5Ω) | Maintains consistent gain across full signal range - critical for audio line-level switching and precision instrumentation multiplexing. |
| Low charge injection (45pC typical) | Minimizes voltage glitch on sampled nodes - essential for data acquisition systems using switched-capacitor ADC drivers. |
| High off-isolation (−60dB at 1MHz) | Attenuates crosstalk between active and inactive channels - improves SNR in multi-channel test fixtures and communication matrix switches. |
| TTL/CMOS-compatible logic inputs | Eliminates need for external level translators when driving from standard microcontrollers or CPLDs operating at 3.3V or 5V. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Single-supply only (+5V to +36V); 2.2Ω RON; 16-TSSOP package; no dual-supply support. | Better for cost-sensitive industrial PLC I/O modules where only positive rails exist and surface-mount is preferred. | Select ADG1419BRUZ when footprint size and single-supply simplicity outweigh need for dual-rail flexibility. |
| TS5A3159DCKR | Lower voltage range (1.65V to 5.5V); 0.75Ω RON; 6-pin SC70; no NC/NO asymmetry - both switches are NO. | Suitable for portable medical devices and battery-powered sensors requiring ultra-low power and compact layout. | Choose TS5A3159DCKR only for low-voltage (<6V), space-constrained designs where complementary switch topology is not required. |
Compared with ADG1419BRUZ and TS5A3159DCKR, the MAX4609CPE+ uniquely supports true dual-supply operation, provides mixed NC/NO topology in one package, and maintains guaranteed RON flatness over ±10V - making it irreplaceable in high-fidelity test and avionics signal routing where rail symmetry and channel complementarity are design-critical.

FAQ
What is the maximum supply voltage rating for MAX4609CPE+?
The MAX4609CPE+ supports absolute maximum ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V, with recommended operating range of ±4.5V to ±20V (dual) or +4.5V to +36V (single). Exceeding these limits risks permanent damage, and proper sequencing (V+ first, then V−, then logic) is required for robust operation.
Does MAX4609CPE+ support rail-to-rail analog signal switching?
Yes, MAX4609CPE+ supports rail-to-rail analog signal switching - signals at COM1/COM2 can swing from V− to V+ without clipping or increased distortion. This capability is confirmed across all operating conditions, including ±15V dual supply and +12V single supply, and is essential for interfacing with op-amps and sensor bridges.
How does the NC/NO configuration of MAX4609CPE+ differ from MAX4607CPE+ and MAX4608CPE+?
The MAX4609CPE+ integrates one normally closed (NC1) and one normally open (NO2) switch - enabling complementary path control in a single package. In contrast, MAX4607CPE+ contains two NC switches, and MAX4608CPE+ contains two NO switches. This mixed topology allows break-before-make or make-before-break behavior without external logic.
What is the guaranteed on-resistance match between the two channels of MAX4609CPE+?
The MAX4609CPE+ guarantees on-resistance match (ΔRON) of ≤0.5Ω max over the full operating temperature range (0°C to +70°C for C-grade), measured at ICCOM = 10mA and VNO/VNC = −5V, 0V, +5V. This specification ensures minimal gain mismatch in differential or ratiometric measurement applications.
Can MAX4609CPE+ operate with a 3.3V logic supply on the VL pin?
Yes, MAX4609CPE+ accepts VL from +2.7V to +5.5V, so a 3.3V logic supply is fully supported. The device maintains TTL/CMOS-compatible input thresholds (+0.8V VIL, +2.4V VIH) regardless of VL voltage, enabling seamless interfacing with 3.3V microcontrollers while retaining full analog rail flexibility (e.g., ±15V analog supplies).
