Product details
Overview
The MAX4599EXT from Maxim Integrated is a low-voltage, single-supply SPDT analog switch in SC70-6 package, designed for bidirectional signal routing with 60Ω max on-resistance at +5V, 30ns max turn-on time, and 5pC max charge injection. It operates from +2.0V to +5.5V and supports audio/video signal paths in space-constrained portable systems.
For engineers reviewing the MAX4599EXT datasheet, MAX4599EXT pinout, MAX4599EXT application, or MAX4599EXT equivalent, key selection criteria include on-resistance flatness (4Ω max), break-before-make timing (10ns min), -76dB off-isolation at 1MHz, and guaranteed performance across -40°C to +85°C.
Technical Context
This device implements a CMOS-based transmission-gate architecture with TTL/CMOS-compatible digital control (VIH = 2.4V min, VIL = 0.8V max) and break-before-make switching to prevent signal shorting during state transitions. Its analog signal range spans rail-to-rail (GND to V+), enabling direct interfacing with ADCs, DACs, and op-amp stages without level-shifting.
The MAX4599EXT achieves 200MHz -3dB on-channel bandwidth and 0.12% THD at 20Hz–20kHz, supported by low leakage (±0.5nA typ at +25°C) and tight RON matching (1Ω max between NO/NC channels). Charge injection is tightly controlled (5pC max) to minimize sampling errors in precision data-acquisition front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +5.5V single supply - enables direct integration with Li-ion battery-powered systems and 3.3V/5V logic domains. |
| On-Resistance (RON) | 60Ω max at +5V - ensures minimal signal attenuation and voltage drop in low-level analog paths. |
| RON Flatness | 4Ω max over full signal range - maintains consistent gain and linearity across GND-to-V+ analog inputs. |
| Charge Injection | 5pC max - reduces settling error and pedestal distortion in sample-and-hold and multiplexed ADC circuits. |
| Turn-On / Turn-Off Time | 30ns / 25ns max - supports high-speed signal routing in communications and test equipment interfaces. |
| Off-Isolation | -76dB at 1MHz - suppresses crosstalk between inactive channels in multi-source audio/video routing. |
| Bandwidth (-3dB) | 200MHz - preserves integrity of fast-switching video signals and wideband RF IF paths. |
Pinout & Package
The MAX4599EXT is housed in a 6-pin SC70 package (1.6mm × 1.6mm × 0.9mm height), optimized for high-density PCB layouts in portable electronics. Pin mapping is validated per Maxim's official datasheet Rev 2 (19-1637).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Digital control input | TTL/CMOS-compatible logic signal that selects NO or NC path; active-high logic sense (IN = HIGH connects COM to NO). |
| 2 V+ | Positive supply rail | Single power source for analog and digital sections; must be applied before analog signals to avoid latch-up. |
| 3 GND | Ground reference | Common return for supply, logic, and analog paths; requires low-impedance connection to minimize noise coupling. |
| 4 NC | Normally closed analog terminal | Connected to COM when IN = LOW; remains isolated when IN = HIGH - used for default-path routing. |
| 5 COM | Analog common node | Bidirectional signal port shared between NO and NC; supports rail-to-rail analog voltages (GND to V+). |
| 6 NO | Normally open analog terminal | Connected to COM when IN = HIGH; electrically isolated when IN = LOW - used for active-path selection. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 10ns minimum dead time prevents momentary shorting between NO and NC during transition - critical for protecting downstream circuitry. |
| RON matching between channels | 1Ω max difference ensures identical gain and phase response when routing differential or dual-signal paths. |
| Rail-to-rail analog signal handling | Supports input/output signals from GND to V+ without clipping - eliminates need for external biasing in sensor or audio interfaces. |
| Low leakage current | ±0.5nA max at +25°C minimizes DC error accumulation in high-impedance sample-and-hold or sensor front-ends. |
| Small-footprint SC70-6 package | 1.6mm × 1.6mm footprint saves >60% board area vs. SOT23-6 - ideal for ultra-compact cellular phone modules and wearables. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4699EXT | Higher RON (120Ω max at +3V), slower switching (tON = 55ns max), same SC70-6 package and pinout. | Targeted for cost-sensitive, lower-bandwidth industrial sensors where speed and THD are less critical. | Select MAX4699EXT only if supply voltage is constrained to +2.7V–+3.6V and bandwidth <50MHz suffices. |
| TMUX1574DSGR | Lower RON (0.5Ω typ), higher supply range (+1.08V to +4.5V), but larger 8-pin VSSOP package and different pin assignment. | Optimized for ultra-low-distortion instrumentation-grade signal chains requiring sub-1Ω matching and 10-bit+ resolution. | Choose TMUX1574DSGR only when RON matching <0.2Ω and THD <0.01% are mandatory - not a drop-in replacement. |
Compared with MAX4599EXT, MAX4699EXT trades speed and linearity for wider low-voltage operation, while TMUX1574DSGR delivers superior analog performance at the cost of PCB area and layout redesign - neither offers pin compatibility, making MAX4599EXT optimal for space-constrained, mid-bandwidth portable designs.

FAQ
What is the operating temperature range for the MAX4599EXT?
The MAX4599EXT is rated for continuous operation from -40°C to +85°C. This industrial-grade temperature range is validated per Maxim's datasheet Rev 2 (19-1637) and applies to all electrical specifications including RON, leakage, and switching times. The SC70-6 package's thermal resistance (θJA = 322°C/W) supports reliable performance in sealed handheld enclosures without forced airflow. MAX4599EXT maintains specified 60Ω max RON and 5pC max charge injection across this full range.
Does the MAX4599EXT support rail-to-rail analog signal operation?
Yes, the MAX4599EXT supports analog signal voltages from GND to V+ across its COM, NO, and NC terminals - confirmed in the "Analog Signal Levels" section of the datasheet. This rail-to-rail capability is enabled by its CMOS transmission-gate design and holds true for all supply voltages from +2.0V to +5.5V. At V+ = +5V, the device sustains <1% RON variation over 0V–5V input swing, ensuring linear gain in sensor and audio interfaces. MAX4599EXT does not require external biasing or level-shifting circuitry.
What is the maximum allowable supply voltage for the MAX4599EXT?
The absolute maximum supply voltage for the MAX4599EXT is +6V, as stated in the Absolute Maximum Ratings table. However, functional operation is guaranteed only from +2.0V to +5.5V per the Electrical Characteristics tables. Exceeding +5.5V risks violating the 60Ω max RON spec and may increase charge injection beyond 5pC. The SC70-6 package's 245mW power dissipation limit at +70°C further constrains sustained operation above +5.5V. MAX4599EXT must never be operated at +6V in production designs.
How does the MAX4599EXT handle power-supply sequencing?
The MAX4599EXT requires V+ to be applied before analog signals or logic inputs to prevent latch-up or ESD damage - a requirement documented in the "Power-Supply Sequencing and Overvoltage Protection" section. If sequencing cannot be guaranteed, Maxim recommends adding external Schottky diodes (D1/D2 in Figure 1) to clamp input voltages. These diodes reduce analog range by ~0.7V but preserve MAX4599EXT functionality. No internal protection circuitry exists; improper sequencing may cause permanent failure.
Is the MAX4599EXT pin-compatible with other variants in the MAX4599 family?
Yes, the MAX4599EXT shares identical pinout and function with MAX4599EUT-T (SOT23-6) and MAX4599ELT-T (µDFN-6) - all three use the same 6-pin configuration: IN, V+, GND, NC, COM, NO. This allows direct substitution across packages without PCB changes, provided thermal and mechanical constraints permit. The SC70-6 footprint of MAX4599EXT measures 1.6mm × 1.6mm, smaller than SOT23-6 (2.9mm × 1.6mm) but larger than µDFN-6 (1.5mm × 1.5mm). MAX4599EXT retains full electrical equivalence across all variants.
