Product details
Overview
The MAX4599EXT-T 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 a +2.0V to +5.5V single supply, delivers ≤60Ω on-resistance at +5V, achieves 30ns max turn-on time and 25ns max turn-off time, and guarantees ≤5pC charge injection - enabling high-fidelity audio/video switching in battery-powered handheld devices.
For engineers reviewing the MAX4599EXT-T datasheet, MAX4599EXT-T pinout, MAX4599EXT-T application, or MAX4599EXT-T equivalent, this device is selected for precision analog path control where low RON flatness (≤4Ω), tight RON matching (≤1Ω), and break-before-make timing (≤10ns) are critical to minimize signal distortion and crosstalk in portable communications circuits.
Technical Context
The MAX4599EXT-T implements a CMOS transmission-gate architecture with TTL/CMOS-compatible digital control, supporting bidirectional analog signal flow between COM and either NO or NC terminals. Its internal structure ensures rail-to-rail analog signal handling (0V to V+) and maintains consistent on-resistance across the full input voltage range - verified at ±2.5°C, ±85°C, and -40°C operating extremes.
Break-before-make switching is hardwired into the logic control path, eliminating simultaneous conduction during state transitions. Charge injection is minimized via matched transistor sizing and layout symmetry, resulting in ≤5pC typical error - critical for sample-and-hold accuracy and low-THD (<0.12%) audio routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +5.5V single supply - enables direct integration with Li-ion, 3.3V, and 5V system rails without level-shifting. |
| On-Resistance (RON) | ≤60Ω max at +5V, +25°C - ensures minimal insertion loss and voltage drop in sensor or audio signal paths. |
| RON Matching | ≤1Ω max between NO and NC channels - preserves signal balance in differential or dual-path routing applications. |
| Charge Injection | ≤5pC max - limits voltage glitch on sampled nodes, supporting <1LSB error in 12-bit+ data acquisition systems. |
| -3dB Bandwidth | 200MHz - supports composite video, USB 1.1, and baseband RF signal switching without attenuation. |
| Off-Isolation | -76dB at 1MHz - suppresses crosstalk between inactive channels in multi-source audio/video matrices. |
| Leakage Current | ±0.5nA max at +25°C - prevents DC offset drift in high-impedance sensor front-ends and precision measurement circuits. |
Pinout & Package
The MAX4599EXT-T is packaged in a 6-pin SC70-6 (X6SN-1) surface-mount package measuring 2.0mm × 1.25mm × 0.9mm, optimized for high-density portable PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | TTL/CMOS-compatible logic signal that selects NO (IN = high) or NC (IN = low); inverted logic sense per truth table. |
| 2 - V+ | Positive supply rail | Single power connection for analog and digital sections; must be applied before analog signals to prevent latch-up. |
| 3 - GND | Analog/digital ground reference | Common return path for supply current and signal references; requires low-impedance PCB connection. |
| 4 - N.C. | Normally closed analog terminal | Connected to COM when IN = low; rated for ±20mA continuous current and ±40mA pulsed current. |
| 5 - COM | Common analog terminal | Bidirectional signal port - serves as input or output depending on routing configuration; supports rail-to-rail voltage swing (0V to V+). |
| 6 - NO | Normally open analog terminal | Connected to COM when IN = high; exhibits identical RON, leakage, and bandwidth specs as N.C. terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed ≤10ns interval prevents momentary shorting between NO and NC paths - essential for avoiding signal transients in audio multiplexing. |
| RON flatness | ≤4Ω max variation over full analog signal range (0V to V+) - maintains consistent gain and linearity in variable-gain amplifier or filter-switching applications. |
| Low THD | 0.12% total harmonic distortion at 20Hz–20kHz - preserves fidelity in headphone drivers and line-out circuits without post-filtering. |
| Ultra-low leakage | ±0.5nA max off-state leakage at +25°C - avoids loading of high-Z sources like piezoelectric sensors or photodiode amplifiers. |
| Small-footprint packaging | SC70-6 footprint (2.0mm × 1.25mm) - reduces board area by >50% vs. comparable SOT23-6 switches while maintaining thermal derating (245mW at +70°C). |

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 at 3.3V), wider supply range (1.08V–5.5V), no guaranteed break-before-make. | Better suited for ultra-low-voltage IoT sensors but lacks MAX4599EXT-T's timing control for glitch-free audio switching. | Select when supply voltage drops below 2.0V; avoid where sub-10ns BBM timing is required. |
| ADG821BRMZ-REEL7 | Lower RON flatness (6Ω max), higher charge injection (12pC max), same SC70-6 package. | Acceptable for general-purpose multiplexing but not recommended for high-THD-sensitive audio or precision sample-and-hold. | Use for cost-sensitive industrial I/O where THD <0.12% and charge injection ≤5pC are non-critical. |
Compared with TMUX1574DSGR and ADG821BRMZ-REEL7, the MAX4599EXT-T uniquely combines guaranteed break-before-make timing, ≤5pC charge injection, and ≤4Ω RON flatness - making it the preferred choice for portable audio, cellular RF calibration, and precision data acquisition where signal integrity is non-negotiable.

FAQ
What is the maximum supply voltage rating for the MAX4599EXT-T?
The MAX4599EXT-T 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. The device delivers optimal RON (≤60Ω) and switching speed (tON ≤30ns) within the +4.5V to +5.5V range, and remains functional down to +2.0V with increased RON (≤105Ω at +2.5V). Always apply V+ before analog signals to prevent latch-up.
Does the MAX4599EXT-T support bidirectional signal flow?
Yes, the MAX4599EXT-T supports fully bidirectional analog signal routing between the COM, NO, and NC terminals. Its CMOS transmission-gate design imposes no directionality - COM can serve as input with NO/NC as outputs, or vice versa. The analog signal range spans 0V to V+, and RON flatness (≤4Ω) and matching (≤1Ω) are maintained regardless of signal direction, making it ideal for shared-path audio and sensor interfaces.
What is the significance of break-before-make timing in the MAX4599EXT-T?
The MAX4599EXT-T guarantees a break-before-make (BBM) interval of ≤10ns, meaning the currently connected path (NO or NC) is fully disconnected before the alternate path connects. This prevents momentary shorting between signal sources - critical in audio routing to eliminate pops/clicks and in RF calibration to avoid injecting test signals into active transceivers. BBM is inherent to the internal logic and requires no external timing control.
How does charge injection affect circuit performance, and what is the MAX4599EXT-T's specification?
Charge injection causes a voltage glitch on high-impedance nodes (e.g., sample-and-hold capacitors) when the switch turns on/off. The MAX4599EXT-T specifies ≤5pC max charge injection, measured with VGEN = 0V, RGEN = 0Ω, and CL = 1.0nF. At this level, a 100pF hold capacitor experiences ≤50mV glitch - manageable with standard offset trimming. This spec is guaranteed across temperature and supply voltage, unlike many alternatives where charge injection rises sharply below 3V.
Can the MAX4599EXT-T operate from a 2.5V supply, and how do key parameters change?
Yes, the MAX4599EXT-T is fully specified for +2.5V operation. At V+ = +2.5V, RON increases to ≤110Ω (typ 65Ω), tON/tOFF extend to ≤60ns/≤45ns, and VIH lowers to +2.0V. All other specs - including ≤5pC charge injection, ≤4Ω RON flatness, and -76dB off-isolation - remain guaranteed. This makes the MAX4599EXT-T viable for ultra-low-power wearable devices where 2.5V rails are common.
