Product details
Overview
MAX4619EUE+T from Analog Devices is a high-speed, low-voltage CMOS triple SPDT analog switch configured for signal routing in precision analog systems. It operates from a single +2V to +5.5V supply, delivers 10ns tOFF and 15ns tON switching, guarantees ≤10Ω on-resistance at +5V, and supports rail-to-rail analog signals up to VCC. It is used in audio/video signal routing where low distortion (<0.017% THD) and high off-isolation (–93dB) are critical.
For engineers reviewing the MAX4619EUE+T datasheet, MAX4619EUE+T pinout, MAX4619EUE+T application, or MAX4619EUE+T equivalent, key selection criteria include guaranteed on-resistance matching (≤1Ω), low charge injection (3pC), TTL/CMOS-compatible logic thresholds, and –96dB crosstalk performance in compact TSSOP-16 packaging.
Technical Context
The MAX4619EUE+T implements three independent SPDT switches with fully bidirectional analog paths, each controlled by a 3-bit address (A/B/C) and global ENABLE input. Its BiCMOS process enables fast switching while maintaining low leakage: ≤1nA off-leakage and ≤1nA on-leakage at +25°C.
All analog terminals tolerate voltages from –0.3V to (VCC + 0.3V), with internal ESD diodes clamping overvoltage events. Logic inputs meet TTL/CMOS thresholds across supply range (+2V to +5.5V), scaling from 0.5V/2.0V at +3V to 0.8V/2.4V at +5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +5.5V single supply - enables direct integration into battery-powered and mixed-signal systems without level-shifting. |
| On-Resistance (RON) | ≤10Ω max at +5V - ensures minimal signal attenuation and gain error in 600Ω audio and data-acquisition paths. |
| Switching Time (tON/tOFF) | 15ns/10ns typical at +5V - supports high-speed multiplexing in sampling systems up to ~30MHz effective bandwidth. |
| Off-Isolation | –93dB at 100kHz - suppresses channel bleed in multi-source audio routing and sensor front-ends. |
| Crosstalk | –96dB at 100kHz - prevents interference between concurrently active SPDT paths in communication circuits. |
| Charge Injection | 3pC - limits voltage glitch on high-impedance nodes (e.g., ADC sample capacitors), reducing settling error. |
| THD | <0.017% at 1VP-P, 20Hz–20kHz, 600Ω load - preserves fidelity in line-level audio signal switching. |
Pinout & Package
MAX4619EUE+T 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 1 is marked by a dot; pin 7 is N.C.; pin 8 is GND; pin 16 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5 | Z1, Z0, Y1, Y0, X1 | SPDT normally open/normally closed analog terminals for Z, Y, and X switch sections - fully bidirectional, interchangeable as input or output. |
| 6 | ENABLE | Active-high digital enable - drives all three SPDTs into high-impedance off-state when logic high; must be tied low for normal operation. |
| 7 | N.C. | No internal connection - left floating; no PCB trace required. |
| 8 | GND | Analog/digital reference ground - shared return for supply, logic, and analog signals; requires low-impedance plane. |
| 9, 10, 11 | C, B, A | 3-bit binary address inputs - select one of two positions per SPDT (Z, Y, X); TTL/CMOS compatible across full supply range. |
| 12, 13, 14, 15 | X0, Y, X, Z | Common analog terminals - X, Y, Z are outputs of respective SPDTs; X0 is Z-section NC terminal - all support rail-to-rail signal swing. |
| 16 | VCC | Positive supply for analog switches and digital logic - powers internal CMOS gates and sets analog voltage limits; must be decoupled locally. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed 1Ω RON match | Ensures amplitude consistency across channels in differential or gain-matched signal paths without calibration. |
| Low 1nA leakage (25°C) | Maintains accuracy in high-impedance sensor interfaces and battery-monitoring circuits over temperature. |
| Pin compatibility with 74HC4053 | Enables drop-in replacement in legacy designs using industry-standard 16-pin SO/TSSOP footprints and logic mapping. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4619ESE+T | Narrow SO-16 package (same pinout, larger footprint, lower thermal resistance) | Better power dissipation in high-duty-cycle switching; less suitable for space-constrained PCBs | Select for thermal-limited environments where TSSOP thermal performance is insufficient. |
| 74HC4053PW,118 | Higher RON (120Ω typ. at +4.5V), slower switching (tON/tOFF ≈ 40ns), no guaranteed RON match | Acceptable for non-critical digital or low-frequency analog routing; not suitable for audio or precision DAQ | Choose only for cost-sensitive, non-performance-critical designs where speed and matching are secondary. |
Compared with MAX4619EUE+T, the MAX4619ESE+T offers identical electrical performance in a thermally robust SO package, while the 74HC4053PW,118 provides basic SPDT functionality at lower cost but with significantly degraded analog performance metrics critical for signal integrity.

FAQ
What is the maximum operating temperature range for the MAX4619EUE+T?
The MAX4619EUE+T is rated for operation from –40°C to +85°C. This extended temperature grade is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet. The "E" suffix explicitly denotes the –40°C to +85°C range, distinguishing it from the "C" grade (0°C to +70°C). Thermal derating applies above +70°C for continuous power dissipation.
Does the MAX4619EUE+T support rail-to-rail analog signal operation?
Yes, the MAX4619EUE+T supports rail-to-rail analog signal operation. Per the Electrical Characteristics tables, the analog-signal range is specified as 0V to VCC for all switch terminals (X_, Y_, Z_, X, Y, Z) under both +5V and +3.3V supply conditions. Internal ESD diodes clamp signals beyond this range, but full rail-to-rail swing is guaranteed within VCC and GND.
What is the guaranteed on-resistance matching between channels for the MAX4619EUE+T?
The MAX4619EUE+T guarantees ≤1Ω on-resistance matching (ΔRON) between channels when operated at +5V supply and +25°C. This specification is explicitly listed in the Electrical Characteristics table under "Switch On-Resistance Match Between Channels" and applies to all three SPDT sections (X, Y, Z) simultaneously.
Is the MAX4619EUE+T pin-compatible with the 74HC4053?
Yes, the MAX4619EUE+T is pin-compatible with the industry-standard 74HC4053 in TSSOP-16 packaging. The datasheet states this explicitly in the Features section and Pin Nomenclature section, confirming identical pin assignments, logic diagrams, and footprint compatibility for single-supply applications.
What is the typical charge injection value for the MAX4619EUE+T, and why does it matter?
The typical charge injection value for the MAX4619EUE+T is 3pC, measured per the test circuit in Figure 5 of the datasheet. This low value minimizes voltage glitches on high-impedance nodes-such as the sample-and-hold capacitor in precision ADC front-ends-reducing settling time and measurement error in data-acquisition systems.
