Product details
Overview
MAX4608CSE+ from Maxim Integrated is a dual, normally open (NO), single-pole single-throw (SPST) CMOS analog switch with 2.5Ω maximum on-resistance, rail-to-rail signal handling (±15V dual or +12V single supply), and 2.5nA max off-leakage at +85°C. It operates across -0°C to +70°C and is used in audio-signal routing, test equipment, and PBX systems where low distortion and mechanical relay replacement are required.
For engineers reviewing the MAX4608CSE+ datasheet, MAX4608CSE+ pinout, MAX4608CSE+ application, or MAX4608CSE+ 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 or +4.5V to +36V single-supply operation, and 16-pin narrow SO package compatibility.
Technical Context
The MAX4608CSE+ implements two independent SPST switches with complementary control logic: IN1 and IN2 drive NO1 and NO2 respectively, turning them ON when logic high. Its BiCMOS process enables low charge injection (45pC typical) and flat on-resistance (≤0.5Ω variation over ±10V signal range), critical for precision signal routing.
All analog terminals (COM1/COM2, NO1/NO2) support rail-to-rail voltages relative to V+ and V−, while digital inputs tolerate TTL/CMOS levels across full supply ranges. The device guarantees ESD protection >2kV per Method 3015.7 and maintains ≤3Ω max RON over temperature (−0°C to +70°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max at TA = TMIN to TMAX - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Match Between Channels | 0.5Ω max - enables matched gain/attenuation in differential or dual-path circuits without calibration |
| Off-Leakage Current | 2.5nA max at +85°C - preserves signal integrity in high-impedance sensor or sample-hold applications |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports industrial, telecom, and test-equipment power architectures |
| Logic Thresholds | +0.8V (low), +2.4V (high) - ensures reliable TTL/CMOS compatibility without level-shifting at +12V or ±15V supplies |
| Turn-On/Off Time | 110ns / 150ns typical at VCOM = ±10V - suitable for medium-speed multiplexing up to ~3MHz switching rate |
| Charge Injection | 45pC typical - limits voltage glitch on sampled nodes, critical for ADC front-end and data acquisition |
Pinout & Package
MAX4608CSE+ is housed in a 16-pin narrow SO (Small Outline) package, RoHS-compliant and lead-free (indicated by '+' suffix). Pin pitch is 0.050", body width 3.9mm, and footprint matches JEDEC MS-012AA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connection (N.C.) | Not internally connected; recommended tied to GND for improved off-isolation and noise immunity |
| 2, 7 | IN1, IN2 | Digital control inputs; active-high logic turns respective NO switch ON (logic high = closed path) |
| 4 | V− | Negative analog supply input; connect to DGND for single-supply operation |
| 5 | GND | Digital ground reference; must be low-impedance connection for stable logic interface |
| 9, 16 | NO1, NO2 | Normally open analog switch terminals; conduct to COMx only when corresponding INx is high |
| 11, 14 | COM1, COM2 | Common analog terminals; bidirectional signal path between COMx and NOx when switch is ON |
| 12 | VL | Logic supply input; decoupled +5V source required for proper input threshold referencing |
| 13 | V+ | Positive analog supply input; sets upper rail for analog signal range and powers internal switch core |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - eliminates clipping in wide-dynamic-range audio or instrumentation paths |
| Guaranteed RON flatness | ≤0.5Ω variation over ±10V signal range - maintains consistent gain/loss across full input swing |
| TTL/CMOS-compatible inputs | +0.8V/+2.4V thresholds with ±5µA input current - interfaces directly with microcontrollers and FPGAs without buffers |
| ESD protection | >2kV per Method 3015.7 - enhances robustness in handling-sensitive production and field environments |
| Low power consumption | <5µA supply currents (I+, I−, IL, IGN D) - enables battery-powered or energy-constrained portable test gear |

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 | Higher RON (3.8Ω typ), wider temp range (−40°C to +125°C), SPI-compatible serial interface | Better suited for high-temp industrial PLCs; requires serial configuration vs. parallel logic control | Select when system-level configurability and extended temperature operation outweigh need for lowest RON |

FAQ
What is the operating temperature range for MAX4608CSE+?
The MAX4608CSE+ is specified for operation from 0°C to +70°C. This commercial-grade temperature range is confirmed in the Ordering Information table and applies specifically to the 'C' grade variant. The '+' suffix denotes RoHS-compliant packaging but does not alter thermal specifications. MAX4608CSE+ maintains all key parameters-including 2.5Ω max RON and 2.5nA max off-leakage-within this range.
Does MAX4608CSE+ support single-supply operation?
Yes, MAX4608CSE+ supports single-supply operation from +4.5V to +36V. In this mode, V− is connected to GND, VL is supplied with +5V, and analog signals swing from 0V to V+. The device retains rail-to-rail capability, TTL/CMOS-compatible logic thresholds, and all key specs including ≤2.5Ω RON. Single-supply use is explicitly validated in the Electrical Characteristics-Single Supply section of the datasheet.
How many switches does MAX4608CSE+ contain, and what is their configuration?
MAX4608CSE+ contains two independent SPST analog switches, both configured as normally open (NO). When IN1 is high, NO1 connects to COM1; when IN2 is high, NO2 connects to COM2. This differs from MAX4607 (dual NC) and MAX4609 (one NC + one NO). The NO configuration is confirmed in the General Description and Pin Configuration diagrams for MAX4608.
What package type is used for MAX4608CSE+?
MAX4608CSE+ uses a 16-pin narrow SO (Small Outline) package, also referred to as SOIC-N or 16-SO. The 'S' in 'CSE' denotes narrow SO, and the '+' indicates lead-free/RoHS compliance. Package dimensions, land pattern (90-0097), and outline number (21-0041) are documented in the Package Information section. It is not pin-compatible with standard-width SOIC-16.
Is MAX4608CSE+ pin-compatible with other variants in the MAX4607/08/09 family?
Yes, MAX4608CSE+ shares identical pinout and package with MAX4607CSE+ and MAX4609CSE+. All three variants use the same 16-pin narrow SO footprint and terminal assignments (e.g., IN1/IN2 at pins 2/7, COM1/COM2 at 11/14, NO1/NO2 at 16/9). Functional differences (NO vs NC vs mixed) do not affect physical layout, enabling drop-in replacement where logic polarity and switch behavior align with system requirements.
