Product details
Overview
The MAX4619CUE+T 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 turn-on time, 10ns turn-off time, and guarantees ≤10Ω on-resistance at +5V - enabling precise audio/video switching and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4619CUE+T datasheet, MAX4619CUE+T pinout, MAX4619CUE+T application, or MAX4619CUE+T equivalent, this device is selected for rail-to-rail analog signal handling, sub-1nA leakage at +25°C, TTL/CMOS logic compatibility, and pin alignment with industry-standard 74HC4053 and MAX4583 switches.
Technical Context
The MAX4619CUE+T implements three independent SPDT switches using BiCMOS process technology, each supporting bidirectional analog signal flow with matched on-resistance (≤1Ω max difference between channels at +5V). Its digital control interface uses address inputs A/B/C and an active-low ENABLE pin to select one of two paths per switch - X0/X1, Y0/Y1, or Z0/Z1 - with break-before-make timing of 0.2–1.5ns.
All analog terminals tolerate rail-to-rail signals (0V to VCC), and internal ESD diodes clamp overvoltage transients. Off-isolation exceeds –93dB and crosstalk remains below –96dB at 100kHz, making it suitable for high-fidelity audio routing and precision sensor multiplexing where channel integrity is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V single supply - supports battery-powered and 3.3V/5V system integration without level shifters. |
| Turn-On / Turn-Off Time | 15ns / 10ns (typ, +5V) - enables fast channel switching in real-time signal routing applications. |
| On-Resistance (RON) | ≤10Ω max at +5V - ensures minimal voltage drop and signal attenuation in low-impedance paths (e.g., 600Ω audio). |
| On-Resistance Match | ≤1Ω max between channels at +5V - maintains consistent gain and phase across switched paths. |
| Off-Leakage Current | ≤1nA at +25°C - preserves accuracy in high-impedance sensor interfaces and battery-critical standby modes. |
| Off-Isolation / Crosstalk | –93dB / –96dB at 100kHz - suppresses interference between adjacent SPDT channels in dense PCB layouts. |
| Total Harmonic Distortion | <0.017% (600Ω load) - meets fidelity requirements for line-level audio and instrumentation-grade signal paths. |
Pinout & Package
MAX4619CUE+T is housed in a 16-pin TSSOP package (U16+2 outline), 4.4mm × 5mm body, 0.65mm pitch, RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y1 (NO) | Normally open terminal of Y-switch - connects to common Y when selected via A/B/C logic. |
| 2 | Y0 (NC) | Normally closed terminal of Y-switch - connected to Y by default unless Y1 is activated. |
| 3 | Z1 (NO) | Normally open terminal of Z-switch - forms second path for Z-channel routing. |
| 4 | Z (COM) | Common terminal of Z-switch - bidirectional I/O node shared with Z0/Z1. |
| 5 | Z0 (NC) | Normally closed terminal of Z-switch - default connection to Z until Z1 is selected. |
| 6 | ENABLE | Active-low global enable - pulls all three SPDT switches to high-impedance open state when logic high. |
| 7 | N.C. | No internal connection - must be left floating or tied to GND; no electrical function. |
| 8 | GND | Analog/digital ground reference - shared return for supply, logic, and signal paths. |
| 9 | C | MSB address input for channel selection - controls Z-switch path (Z0 vs Z1) and contributes to X/Y decoding. |
| 10 | B | Middle address bit - jointly selects X0/X1, Y0/Y1, and Z0/Z1 states with A and C. |
| 11 | A | LSB address input - completes 3-bit decode for simultaneous triple SPDT configuration. |
| 12 | X0 (NC) | Normally closed terminal of X-switch - default path for X unless X1 is selected. |
| 13 | X1 (NO) | Normally open terminal of X-switch - activated when A/B/C = 001, 011, 101, or 111. |
| 14 | X (COM) | Common terminal of X-switch - bidirectional node routed to X0 or X1 based on address. |
| 15 | Y (COM) | Common terminal of Y-switch - carries signal between Y0 and Y1 under address control. |
| 16 | VCC | Positive supply for analog switches and digital logic - sets analog signal range (0V to VCC) and logic thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full 0V to VCC swing on all switch terminals - eliminates clipping in single-supply audio and sensor interfaces. |
| Guaranteed 1Ω RON match (+5V) | Ensures amplitude and phase consistency across three independent SPDT paths - critical for balanced signal routing. |
| Low charge injection (3pC) | Minimizes voltage glitch during switching - preserves DC accuracy in precision ADC front-ends and sample-hold circuits. |
| TTL/CMOS-compatible logic thresholds | Inputs accept 0.8V/2.4V thresholds at +5V supply - interoperable with standard microcontrollers and FPGAs without glue logic. |
| Pin compatibility with 74HC4053/MAX4583 | Enables drop-in replacement in existing designs using industry-standard 16-pin SO/TSSOP footprints and logic mapping. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4583CSE+T | Same pinout, identical truth table, but higher RON (15Ω max at +5V) and slower tON/tOFF (25ns/15ns). | Lower bandwidth and higher insertion loss - less suitable for >1MHz audio or precision data acquisition. | Select MAX4583CSE+T only if legacy design reuse or cost sensitivity outweighs performance requirements. |
| 74HC4053PW,118 | Pin-compatible, but higher RON (120Ω typ at +4.5V), no guaranteed RON match, and no 2V operation. | Limited to 3V–5V systems; unsuitable for battery-powered 2.5V operation or precision matching-critical applications. | Choose 74HC4053PW,118 for non-critical general-purpose switching where cost and availability dominate. |
Compared with MAX4583CSE+T and 74HC4053PW,118, the MAX4619CUE+T provides superior on-resistance (≤10Ω), tighter channel matching (≤1Ω), faster switching (15ns/10ns), and extended low-voltage operation down to +2V - making it optimal for high-fidelity, low-power, and precision analog routing.

FAQ
What is the maximum operating supply voltage for the MAX4619CUE+T?
The MAX4619CUE+T supports a single-supply voltage range from +2V to +5.5V. Absolute maximum rating is +6V on VCC relative to GND. Operation beyond +5.5V risks permanent damage and violates the device's specified electrical characteristics - always limit VCC to ≤+5.5V in production designs using MAX4619CUE+T.
Does the MAX4619CUE+T support bidirectional signal flow?
Yes, the MAX4619CUE+T supports fully bidirectional analog signal flow on all switch terminals (X, Y, Z, X0/X1, Y0/Y1, Z0/Z1). The device has no intrinsic directionality - signals pass equally well from common to normally closed/open terminals or vice versa, as confirmed in the Applications Information section of the MAX4619CUE+T datasheet.
What is the guaranteed on-resistance match between channels for the MAX4619CUE+T?
The MAX4619CUE+T guarantees ≤1Ω on-resistance match (ΔRON) between its three SPDT channels when operated at +5V supply and TA = +25°C. This specification ensures consistent gain, phase, and settling behavior across X, Y, and Z paths - a key requirement for matched signal routing in differential or multi-channel systems using MAX4619CUE+T.
Can the MAX4619CUE+T be used with a +3.3V supply?
Yes, the MAX4619CUE+T is fully specified for +3.3V operation: on-resistance is ≤20Ω max, switching times are 20ns/15ns (tON/tOFF), and logic thresholds adjust to 2.0V/0.5V. All parameters remain guaranteed across 0°C to +70°C - making MAX4619CUE+T compatible with modern 3.3V microcontroller interfaces and low-voltage portable systems.
Is the ENABLE pin active-high or active-low on the MAX4619CUE+T?
The ENABLE pin on the MAX4619CUE+T is active-low: driving it logic high (≥2.4V at +5V supply) forces all three SPDT switches into high-impedance open state, regardless of A/B/C address inputs. Pulling ENABLE low (≤0.8V) enables normal address-controlled switching - a critical feature for system-level power gating and fault-safe isolation in designs using MAX4619CUE+T.
