Product details
Overview
The MAX4599EXT+TG50 from Maxim Integrated is a single-pole/double-throw (SPDT) analog switch designed for low-voltage signal routing in space-constrained systems. It operates from +2.0V to +5.5V, delivers ≤60Ω on-resistance at +5V, achieves 30ns max tON/25ns max tOFF, and guarantees ≤5pC charge injection - enabling high-fidelity audio/video switching in battery-powered handheld devices.
For engineers reviewing the MAX4599EXT+TG50 datasheet, MAX4599EXT+TG50 pinout, MAX4599EXT+TG50 application, or MAX4599EXT+TG50 equivalent, key selection criteria include its SC70-6 package footprint, break-before-make timing, ±0.5nA leakage at +25°C, 200MHz -3dB bandwidth, and TTL/CMOS logic compatibility across full supply range.
Technical Context
This SPDT switch uses CMOS transmission-gate architecture with integrated level-shifting circuitry to ensure TTL/CMOS-compatible control inputs across its entire +2.0V to +5.5V supply range. Its bidirectional analog path supports rail-to-rail signal swing (0V to V+) with minimal RON variation - flatness ≤4Ω and matching ≤1Ω between NO and NC channels.
Break-before-make timing (tBBM ≤10ns at +25°C) prevents momentary shorting during state transitions. Charge injection (≤5pC) and low off-capacitance (8pF per channel) preserve signal integrity in sample-and-hold and multiplexed data-acquisition paths without requiring external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +5.5V single supply - enables direct interface with Li-ion, 3.3V, and 5V logic domains without level shifters |
| On-Resistance (RON) | ≤60Ω max at +5V - ensures <0.1% gain error in 600Ω audio paths and minimal voltage drop in sensor signal chains |
| RON Matching | ≤1Ω max between NO/NC channels - critical for balanced differential switching and THD-sensitive applications |
| Charge Injection | ≤5pC max - limits voltage glitch on hold capacitors to <5mV in 1nF sample circuits |
| -3dB Bandwidth | 200MHz - supports composite video, USB 1.1, and baseband RF signal routing without attenuation |
| Off-Isolation | -76dB at 1MHz - suppresses crosstalk between inactive channels in multi-source audio/video systems |
| Leakage Current | ±0.5nA max at +25°C - preserves battery life in always-on monitoring nodes and reduces offset drift in precision front-ends |
Pinout & Package
MAX4599EXT+TG50 is packaged in a RoHS-compliant 6-pin SC70-6 (X6SN-1) outline with 0.65mm pitch, measuring 2.0mm × 1.25mm × 0.95mm - optimized for ultra-compact portable PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital Control Input | TTL/CMOS-compatible logic input; active-high control with VIH ≥2.4V at +5V supply |
| 2 (V+) | Positive Supply Rail | Single power connection; must be applied before analog signals to prevent latch-up |
| 3 (GND) | Analog/Digital Ground | Common reference for all analog and digital signals; requires low-impedance PCB return path |
| 4 (N.C.) | Normally Closed Analog Terminal | Connects to COM when IN = low; open-circuit when IN = high - used for default-path routing |
| 5 (COM) | Common Analog Terminal | Bidirectional signal port; connects to either N.C. or N.O. depending on logic state of IN |
| 6 (N.O.) | Normally Open Analog Terminal | Connects to COM when IN = high; open-circuit when IN = low - used for active-path selection |
Key Features
| Feature | Design Value |
|---|---|
| Break-Before-Make Switching | tBBM ≤10ns ensures no overlap between N.C. and N.O. conduction - eliminates signal shorting during transition |
| Rail-to-Rail Analog Range | Supports 0V to V+ signal swing with <5Ω RON variation - preserves dynamic range in ADC driver and DAC output stages |
| Low THD+N | 0.12% at 20Hz–20kHz into 600Ω - meets CD-quality audio routing requirements without post-filtering |
| Ultra-Low Leakage | ±0.5nA max off-leakage at +25°C - extends battery runtime in always-on IoT sensors and medical patch monitors |
| Small-Signal Integrity | 8pF off-capacitance and 20pF on-capacitance minimize loading on high-Z sources like piezoelectric sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX1574DSGR | Higher RON (120Ω typ), wider supply (1.08V–5.5V), no guaranteed charge injection spec | Optimized for ultra-low-voltage MCU I/O expansion, not precision signal routing | Select when operating below +2.0V or needing 1.08V logic compatibility; avoid for audio/THD-critical use |
| ADG849YRMZ-REEL7 | Lower RON (0.5Ω typ), narrower supply (+1.8V to +5.5V), higher cost, 8-pin MSOP package | Targeted at high-precision instrumentation where sub-ohm matching is mandatory | Select only when RON matching <0.5Ω is required; MAX4599EXT+TG50 offers better cost/performance for consumer audio |
Compared with TMUX1574DSGR and ADG849YRMZ-REEL7, the MAX4599EXT+TG50 delivers optimal balance of low distortion (0.12% THD), tight RON matching (≤1Ω), and SC70-6 footprint - making it preferred for space-constrained, battery-operated audio/video routing where signal fidelity and board area are jointly constrained.

FAQ
What is the maximum supply voltage rating for MAX4599EXT+TG50?
The MAX4599EXT+TG50 has an absolute maximum supply voltage (V+) of +6V, but its specified operational range is +2.0V to +5.5V. Exceeding +6V risks permanent damage per Absolute Maximum Ratings. For reliable operation, keep V+ within +5.5V and ensure V+ is powered before applying analog signals or logic inputs to prevent latch-up.
Does MAX4599EXT+TG50 support bidirectional analog signal flow?
Yes, the MAX4599EXT+TG50 is fully bidirectional: the COM, NO, and NC terminals can serve as either input or output ports. This allows flexible routing in both source-to-load and load-to-source configurations - essential for applications like audio loopback testing and sensor excitation/sensing sharing the same analog path.
What is the guaranteed charge injection specification for MAX4599EXT+TG50?
The MAX4599EXT+TG50 guarantees ≤5pC maximum charge injection at +25°C, measured with VGEN = 0V, RGEN = 0Ω, and CL = 1.0nF. This low value minimizes voltage glitches on hold capacitors in sample-and-hold circuits, limiting step errors to <5mV - critical for maintaining accuracy in successive-approximation ADC front-ends.
How does the on-resistance of MAX4599EXT+TG50 vary with supply voltage?
At +25°C, MAX4599EXT+TG50 exhibits 40Ω typical / 60Ω maximum RON at +5V, rising to 65Ω typical / 95Ω maximum at +3V, and 65Ω typical / 110Ω maximum at +2.5V. The increase reflects MOSFET channel resistance scaling inversely with VGS - design margin must account for this when operating near minimum supply.
Is MAX4599EXT+TG50 compatible with 1.8V logic control signals?
No - MAX4599EXT+TG50 requires VIH ≥2.4V (for +5V supply) or ≥2.0V (for +3V supply) to guarantee logic high recognition. A 1.8V GPIO will not reliably drive the IN pin high across temperature and process variation. Level-shifting or a logic-compatible alternative like TMUX1574 is required for true 1.8V control.
