Product details
Overview
MAX4649EKA+G0N from Maxim Integrated is a dual-supply, single-pole/double-throw (SPDT) analog switch in an 8-pin SOT23 package. It features 45Ω max on-resistance, ±4.5V to ±20V dual supply operation (or +9V to +36V single supply), 130ns max transition time, guaranteed break-before-make switching with 5ns delay, and rail-to-rail signal handling - used for signal routing in telecom test equipment and avionics systems.
For engineers reviewing the MAX4649EKA+G0N datasheet, MAX4649EKA+G0N pinout, MAX4649EKA+G0N application, or MAX4649EKA+G0N equivalent, key selection criteria include on-resistance flatness (7Ω max), off-isolation (–92dB at 1MHz), crosstalk (–92dB), leakage current (2nA max at +25°C), and compatibility with TTL/CMOS logic inputs without requiring a separate VL supply.
Technical Context
The MAX4649EKA+G0N uses CMOS switch architecture to support bidirectional rail-to-rail analog signal conduction across its COM–NO and COM–NC paths. Its break-before-make timing ensures no transient shorting during state transitions, with guaranteed 5ns minimum dead time under ±15V supplies and 300Ω load.
It operates with independent logic-level thresholds referenced to GND (VIH = 2.4V, VIL = 0.8V), eliminating need for level-shifting circuitry. Internal protection diodes clamp signals exceeding V+ or V−, but require proper power sequencing (V+ first, then V−, then control inputs) to avoid overstress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 45Ω max at ±15V supplies - ensures minimal signal attenuation and voltage drop in precision analog routing paths. |
| RON Matching | 5Ω max difference between NO and NC channels - critical for balanced differential signal switching and relay replacement accuracy. |
| RON Flatness | 7Ω max variation over full signal range - maintains consistent gain and linearity across rail-to-rail input voltages. |
| Off-Isolation / Crosstalk | –92dB at 1MHz - suppresses interference between switched channels in high-density signal multiplexing. |
| Transition Time | 130ns max - enables reliable switching of audio-band and low-speed digital control signals without timing skew. |
| Break-Before-Make Delay | 5ns guaranteed - prevents momentary short-circuit between NO and NC paths during switching, essential for fault-tolerant redundant systems. |
| Off-Leakage Current | 2nA max at +25°C - preserves signal integrity in high-impedance sensor interfaces and battery-powered measurement circuits. |
Pinout & Package
MAX4649EKA+G0N is housed in an 8-pin SOT23 package (JEDEC MO-178AA), measuring 2.9mm × 1.6mm × 1.1mm, with gull-wing leads and thermal pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - COM | Analog Switch Common Terminal | Shared signal path; connects to either NO or NC depending on IN logic state - must be routed with controlled impedance for high-fidelity analog signals. |
| 2 - NC | Normally Closed Terminal | Connected to COM when IN = low (0.8V); open when IN = high - used for default-path signal routing or fail-safe configurations. |
| 3 - GND | Ground Reference | Logic ground reference for control inputs; not tied to analog signal return - requires separate low-noise grounding from analog sections. |
| 4 - V+ | Positive Supply Rail | Accepts +9V to +36V (single) or up to +20V (dual); powers internal CMOS switches and logic - must be decoupled near pin with ≥1µF ceramic capacitor. |
| 5 - N.C. | No Connection | Internally unconnected; must remain floating - no trace or solder mask required; PCB pad may be omitted per layout guidelines. |
| 6 - IN | Digital Control Input | TTL/CMOS-compatible (VIH = 2.4V, VIL = 0.8V); drives internal switch logic - compatible with microcontroller GPIO without level translation. |
| 7 - V− | Negative Supply Rail | Accepts –4.5V to –20V (dual supply only); establishes negative analog signal swing capability - must be decoupled independently from V+. |
| 8 - NO | Normally Open Terminal | Connected to COM when IN = high (2.4V); open when IN = low - used for active-path selection in multiplexer or signal-gating applications. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ without clipping - enables direct interfacing with op-amps, ADCs, and DACs operating at full supply rails. |
| No VL Logic Supply Required | Accepts standard 0V/3.3V/5V logic inputs referenced to GND - eliminates need for auxiliary voltage rail and simplifies system power architecture. |
| Guaranteed Break-Before-Make | 5ns minimum dead time ensures no overlap between NC and NO conduction - prevents short-circuit faults in safety-critical avionics and telecom infrastructure. |
| Low Charge Injection (1pC typ) | Minimizes voltage glitch on high-impedance nodes during switching - critical for sample-and-hold circuits and precision instrumentation front-ends. |
| High Off-Isolation (–92dB) | Effectively isolates unused signal paths at 1MHz - reduces crosstalk in multi-channel test equipment and DSL line card designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4648EKA+T | Same pinout, identical specs except 100Ω max RON at ±15V - higher on-resistance limits use in precision gain paths. | Lower-cost option for non-critical signal routing where RON matching and flatness are less constrained. | Select MAX4648EKA+T only if 45Ω RON is not required and budget sensitivity outweighs performance trade-offs. |
| ADG1419BRMZ-REEL7 | 40Ω max RON, ±15V rating, but requires VL supply for logic interface and uses MSOP-10 package - different footprint and biasing requirements. | Better RON spec but incompatible pinout and added supply complexity - unsuitable for drop-in replacement in existing SOT23-8 layouts. | Choose ADG1419BRMZ-REEL7 only for new designs prioritizing lowest possible RON and willing to redesign PCB and add VL rail. |
Compared with MAX4649EKA+G0N, MAX4648EKA+T offers cost savings at the expense of on-resistance performance, while ADG1419BRMZ-REEL7 improves RON but introduces layout and supply design overhead - making MAX4649EKA+G0N optimal for space-constrained, dual-supply, rail-to-rail applications needing guaranteed break-before-make timing.

FAQ
What supply voltage ranges does the MAX4649EKA+G0N support?
The MAX4649EKA+G0N supports dual supplies from ±4.5V to ±20V and single supplies from +9V to +36V. Operation outside these ranges violates absolute maximum ratings and risks permanent damage. The device is fully specified at ±15V and +12V, with on-resistance and timing parameters guaranteed across the full temperature range (–40°C to +85°C) under those conditions. Always observe proper power sequencing: apply V+ first, then V−, then logic inputs.
Does the MAX4649EKA+G0N require a separate logic supply voltage (VL)?
No, the MAX4649EKA+G0N does not require a separate VL supply. Its IN pin accepts standard TTL/CMOS logic levels (VIH = 2.4V, VIL = 0.8V) referenced directly to GND, regardless of whether it is powered from dual ±15V or single +12V supplies. This eliminates the need for level translators or auxiliary rails, simplifying board design and reducing BOM count - a key advantage over many competing analog switches like the ADG1419.
What is the guaranteed break-before-make timing for the MAX4649EKA+G0N?
The MAX4649EKA+G0N guarantees a minimum break-before-make delay of 5ns under ±15V supplies with RL = 300Ω and CL = 35pF. This specification ensures no overlap between NC and NO conduction states during switching transitions, preventing momentary shorts that could damage downstream circuitry or corrupt data. The value is tested and guaranteed across the full operating temperature range, not just typical at +25°C.
Can the MAX4649EKA+G0N handle rail-to-rail analog signals?
Yes, the MAX4649EKA+G0N is explicitly rated for rail-to-rail analog signal handling - meaning it passes signals from V− to V+ without clipping or distortion. This capability is enabled by its CMOS switch architecture and verified across all supply configurations (±15V, +12V). Signal integrity is preserved via low charge injection (1pC typ), low THD (0.015%), and flat on-resistance (≤7Ω variation), making it suitable for precision instrumentation and audio applications.
What is the maximum allowable voltage difference between V+ and V− for the MAX4649EKA+G0N?
The absolute maximum voltage difference between V+ and V− for the MAX4649EKA+G0N is +44.0V, as specified in the Absolute Maximum Ratings table. Exceeding this limit - even briefly - may cause irreversible damage. For reliable operation, the device is characterized and guaranteed over ±4.5V to ±20V (i.e., 9V to 40V total span), with recommended derating for long-term reliability. Always ensure V+ and V− remain within their individual absolute limits (–0.3V to +44.0V and –44.0V to +0.3V respectively).
