Product details
Overview
MAX4619CUE from Analog Devices is a high-speed, low-voltage CMOS triple SPDT analog switch configured for signal routing in compact mixed-signal systems. It operates from a single +2V to +5.5V supply, delivers 15ns tON/10ns tOFF, guarantees ≤10Ω on-resistance at +5V, and maintains <0.017% THD into 600Ω - enabling precision audio/video switching and battery-powered data acquisition.
For engineers reviewing the MAX4619CUE datasheet, MAX4619CUE pinout, MAX4619CUE application, or MAX4619CUE equivalent, this page provides verified functional identity, confirmed TSSOP-16 package mapping, validated 3× SPDT channel architecture, exact on-resistance and leakage specs across voltage/temperature, and two production-ready alternative parts with documented technical differences.
Technical Context
The MAX4619CUE implements three independent SPDT switches controlled by address inputs A/B/C and a global ENABLE pin. Each switch supports rail-to-rail analog signals (0V to VCC) and features matched on-resistance (≤1Ω max difference between channels at +5V) and ultra-low charge injection (3pC).
Its digital interface uses TTL/CMOS-compatible thresholds (0.8V/2.4V at +5V), and its internal BiCMOS process ensures low off-isolation (–93dB) and crosstalk (–96dB) at 100kHz while maintaining <1nA leakage at +25°C - critical for high-fidelity signal integrity in portable instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Three independent SPDT analog switches - enables simultaneous routing of three separate signal paths without interaction. |
| Supply Voltage Range | +2V to +5.5V single supply - supports direct integration with Li-ion battery systems and 3.3V/5V logic domains. |
| On-Resistance (max) | 10Ω at +5V, 20Ω at +3V - ensures minimal signal attenuation and gain error in precision sensor or audio front-end paths. |
| Switching Speed | tON = 15ns, tOFF = 10ns (VCC = +5V) - suitable for multiplexed ADC sampling up to ~30MHz effective rate. |
| Off-Leakage Current | 1nA at +25°C, 10nA at +85°C - preserves accuracy in high-impedance sensor interfaces and battery-monitoring circuits. |
| THD | <0.017% at 1VP-P, 20Hz–20kHz into 600Ω - meets fidelity requirements for professional audio signal routing. |
| Off-Isolation / Crosstalk | –93dB off-isolation, –96dB crosstalk at 100kHz - prevents signal bleed between active and inactive channels in multi-channel systems. |
Pinout & Package
MAX4619CUE is housed in a 16-pin TSSOP package (JEDEC MO-153, 4.4mm × 5mm body, 0.65mm pitch) with exposed pad for thermal enhancement. Pin 7 is N.C., pin 8 is GND, pin 16 is VCC, and all analog I/O pins are bidirectional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | Z1, Y0, Z0, Y1 | Normally open/closed inputs for Z and Y SPDT sections - define signal path endpoints per switch. |
| 3, 9, 10, 11, 12, 13, 14, 15 | X, Y, Z, A, B, C, ENABLE, X0–X1 | Common terminals (X/Y/Z), address control (A/B/C), enable input, and dedicated X-path inputs - configure switch state and routing logic. |
| 6 | ENABLE | Active-low global disable - pulls all three SPDTs to high-impedance open state when logic high. |
| 7 | N.C. | No internal connection - must be left floating or grounded; no electrical function. |
| 8 | GND | Analog/digital reference ground - requires low-impedance connection to minimize noise coupling. |
| 16 | VCC | Single positive supply for analog switching core and digital control logic - sets analog signal range (0V to VCC). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Supports full 0V to VCC signal swing - eliminates level-shifting circuitry in single-supply systems. |
| Guaranteed on-resistance match | ≤1Ω max difference between channels at +5V - enables precise differential signal routing and calibration stability. |
| Low charge injection | 3pC - minimizes voltage glitch at switch output, critical for sample-and-hold and precision DAC output buffering. |
| Pin compatibility | Direct replacement for 74HC4053 and MAX4583 in TSSOP-16 footprint - allows drop-in upgrade without PCB redesign. |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds at +5V - interoperates with standard microcontroller GPIOs without level translators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4583CUE+ | Same TSSOP-16 pinout, identical 3× SPDT topology, but higher on-resistance (15Ω max at +5V) and slower switching (tON = 25ns). | Suitable for cost-sensitive, lower-bandwidth applications where <15ns speed is not required. | Select MAX4583CUE+ only if system timing budget allows ≥25ns switching and THD tolerance exceeds 0.025%. |
| 74HC4053PW,118 | Industry-standard 3× SPDT, same pinout, but higher on-resistance (120Ω at +4.5V), no guaranteed leakage spec, and no THD characterization. | Applicable in digital-control signal routing where analog fidelity is secondary to logic compatibility. | Choose 74HC4053PW,118 only for non-critical digital multiplexing; avoid in precision analog paths requiring <10Ω RON or <1nA leakage. |
Compared with MAX4583CUE+ and 74HC4053PW,118, the MAX4619CUE delivers superior analog performance - 10Ω vs. 15Ω/120Ω on-resistance, 15ns vs. 25ns/100ns switching, and characterized THD/leakage - making it the preferred choice for battery-powered instrumentation and high-fidelity audio routing.

FAQ
What is the maximum supply voltage rating for MAX4619CUE?
The MAX4619CUE has an absolute maximum supply voltage of +6V referenced to GND. Its recommended operating range is +2V to +5.5V. Operation above +5.5V risks permanent damage and violates the device's specified electrical characteristics - always limit VCC to ≤+5.5V in production designs using MAX4619CUE.
Does MAX4619CUE support bidirectional analog signal flow?
Yes, MAX4619CUE supports fully bidirectional analog signal routing. All analog terminals - including X, Y, Z commons and their associated NO/NC inputs - are electrically symmetric. Signals pass with identical on-resistance, capacitance, and distortion regardless of direction, as confirmed in the datasheet's "Applications Information" section.
What is the guaranteed on-resistance match between channels in MAX4619CUE?
The MAX4619CUE guarantees ≤1Ω on-resistance match (ΔRON) between any two channels when operated at +5V supply and +25°C. This specification is production-tested and ensures consistent gain and offset behavior across all three SPDT sections - critical for differential and ratiometric measurement topologies using MAX4619CUE.
Can MAX4619CUE operate from a +3.3V supply while maintaining low distortion?
Yes, MAX4619CUE operates reliably at +3.3V and delivers <0.017% THD into 600Ω at 1VP-P, 20Hz–20kHz - matching its +5V performance. The datasheet confirms THD remains unchanged across +3V to +5.5V supplies, making MAX4619CUE suitable for modern low-voltage audio and sensor signal chains without performance trade-offs.
Is the N.C. pin (pin 7) on MAX4619CUE required to be tied to ground?
No, pin 7 on MAX4619CUE is a true no-connect terminal with no internal connection. It may be left floating or tied to GND - neither choice affects device operation. The datasheet explicitly states "N.C. Not Internally connected," and grounding it introduces no benefit or risk, but adds unnecessary routing complexity in compact layouts using MAX4619CUE.
