Product details
Overview
MAX4564EUA+ from Maxim Integrated is a low-voltage, dual-supply SPDT analog switch with enable, designed for ±1.8V to ±6V or +1.8V to +12V operation. It delivers 40Ω typical on-resistance at ±5V, 60ns max turn-on time, 1nA max leakage at +25°C, and guaranteed break-before-make switching-ideal for precision audio routing in portable instrumentation.
For engineers reviewing the MAX4564EUA+ datasheet, MAX4564EUA+ pinout, MAX4564EUA+ application, or MAX4564EUA+ equivalent, key selection criteria include on-resistance flatness (10Ω max), charge injection (3pC typ), off-isolation (–77dB at 1MHz), and µMAX® 8-pin RoHS-compliant packaging for space-constrained signal-path designs.
Technical Context
The MAX4564EUA+ implements CMOS-based rail-to-rail analog switching with independent TTL/CMOS-compatible digital control of NO and NC paths via EN and IN inputs. Its break-before-make architecture prevents signal shorting during state transitions, and internal protection diodes clamp input signals exceeding V+ or V−.
It supports dual-supply operation (±1.8V to ±6V) and single-supply mode (+1.8V to +12V), with analog signal range spanning V− to V+. On-resistance varies less than 10Ω over full signal swing (RFLAT(ON) ≤ 10Ω), and channel matching (∆RON ≤ 3Ω typ) ensures balanced performance in differential or stereo paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 40Ω typ (60Ω max) at ±5V - enables low insertion loss in audio/video signal chains |
| On-Resistance Flatness | 10Ω max - maintains consistent gain and THD across full analog input range (±5V) |
| Turn-On / Turn-Off Time | 60ns / 40ns max at ±5V - supports fast multiplexing in test equipment and sample-and-hold systems |
| Charge Injection | 3pC typ - minimizes voltage glitch at COM node during switching, critical for precision ADC front-ends |
| Off-Isolation | –77dB at 1MHz - suppresses crosstalk between inactive channels in multi-signal routing |
| Leakage Current | ±1nA max at +25°C - preserves DC accuracy in high-impedance sensor interfaces and battery-monitoring circuits |
| Supply Range | ±1.8V to ±6V dual or +1.8V to +12V single - accommodates Li-ion, USB, and industrial supply rails |
Pinout & Package
The MAX4564EUA+ is housed in an 8-pin µMAX® package (pin-compatible with industry-standard 8-pin SO and SOT23 footprints but with smaller 3mm × 3mm body). Thermal resistance θJA = 222°C/W; derating 4.5mW/°C above +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (COM) | Analog common terminal | Signal path junction point; connects to either NO or NC based on logic state; rail-to-rail capable |
| 2 (EN) | Enable control input | Active-low: drives low for normal SPDT operation; high disconnects both NO and NC |
| 3 (V−) | Negative supply rail | Supports dual-supply operation down to –1.8V; must be powered before logic inputs |
| 4 (GND) | Ground reference | System ground return; not used as signal reference in dual-supply mode |
| 5 (IN) | Digital control input | TTL/CMOS-compatible; controls NO/NC selection when EN = low |
| 6 (NO) | Normally open analog terminal | Connects to COM only when IN = high and EN = low; unconnected otherwise |
| 7 (NC) | Normally closed analog terminal | Connects to COM only when IN = low and EN = low; unconnected otherwise |
| 8 (V+) | Positive supply rail | Supports single/dual supplies up to +12V or ±6V; powers internal switch matrix and logic |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs from V− to V+ without clipping-enables full dynamic range in ±5V op-amp stages |
| Guaranteed break-before-make | 5ns min / 15ns max tBBM at ±5V-prevents momentary shorting in sensitive feedback or power-path switching |
| Low crosstalk (–72dB) | Isolates active and inactive signal paths at 1MHz-critical for simultaneous multi-channel monitoring |
| Bandwidth (–3dB) | >450MHz typ-preserves integrity of video, RF sampling, and wideband test signals |
| Low power consumption | 5µW typ at ±5V-extends battery life in handheld audio analyzers and portable data loggers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG774ACRUZ | Single +1.8V to +5.5V supply only; 4.5Ω typical RON; no dual-supply support | Not suitable for ±5V signal routing; limited to unipolar systems | Select when operating exclusively from low-voltage single supply and lowest RON is critical |
| TS5A23157DCUR | 3.3V-only logic compatibility; 0.9Ω typical RON at +3.3V; no break-before-make guarantee | Lacks guaranteed BBM timing; unsuitable for fault-sensitive power or feedback paths | Choose for cost-sensitive consumer audio where BBM is non-critical and supply is fixed at 3.3V |
Compared with ADG774ACRUZ and TS5A23157DCUR, the MAX4564EUA+ uniquely supports true dual-supply operation with guaranteed break-before-make timing, making it the only option among the three for ±5V rail-to-rail signal switching in industrial and test equipment.

FAQ
What supply configurations does the MAX4564EUA+ support?
The MAX4564EUA+ operates from dual supplies (±1.8V to ±6V) or a single supply (+1.8V to +12V). At ±5V, it achieves 40Ω typical on-resistance and 60ns/40ns turn-on/turn-off times. The device requires proper sequencing: V+ first, then V−, then logic inputs. Exceeding absolute maximum ratings (e.g., V+ to V− > +13V) risks permanent damage.
Does the MAX4564EUA+ provide guaranteed break-before-make switching?
Yes, the MAX4564EUA+ guarantees break-before-make operation with a minimum interval of 5ns and maximum of 15ns at ±5V. This is confirmed in the Electrical Characteristics table under "Break-Before-Make Time (Note 6)" and is essential for preventing signal shorting in feedback loops or power-path switching. The feature is inherent to the internal CMOS switch architecture and does not require external timing control.
What is the maximum analog signal range supported by the MAX4564EUA+?
The MAX4564EUA+ supports analog signals from V− to V+ across its entire operating supply range. At ±5V supplies, the signal range is –5V to +5V; at +5V single supply, it is 0V to +5V. This rail-to-rail capability is enabled by its CMOS construction and allows full utilization of ADC or amplifier input ranges without level-shifting circuitry.
How does charge injection affect system performance in the MAX4564EUA+?
The MAX4564EUA+ exhibits 3pC typical charge injection, measured with VGEN = 0 and CL = 100pF. In sample-and-hold or high-impedance sensor interfaces, this causes a voltage glitch ∆V = Q/CL at the COM node during switching. For a 100pF hold capacitor, the glitch is 30mV-requiring careful layout and possibly a small series resistor to limit peak current and reduce settling time.
Is the MAX4564EUA+ RoHS-compliant and lead-free?
Yes, the MAX4564EUA+ is RoHS-compliant and lead-free, as indicated by the "+" suffix in its ordering code. The µMAX® package uses matte tin lead finish and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements. Full compliance documentation, including material declarations and test reports, is available through Maxim's official product page and authorized distributors.
