Product details
Overview
MAX4619CUE+ from Analog Devices is a high-speed, low-voltage CMOS analog SPDT switch IC configured as three independent single-pole/double-throw switches. 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 signal routing in battery-powered audio/video systems.
For engineers reviewing the MAX4619CUE+ datasheet, MAX4619CUE+ pinout, MAX4619CUE+ application, or MAX4619CUE+ equivalent, this page provides verified electrical specs, TSSOP-16 pin mapping, real-world use cases in low-voltage data acquisition and communications circuits, and two validated alternative parts with documented functional and packaging differences.
Technical Context
The MAX4619CUE+ implements three fully independent SPDT switches, each with rail-to-rail analog signal handling capability and TTL/CMOS-compatible digital control inputs (A, B, C, ENABLE). Its BiCMOS process ensures low charge injection (3pC) and tight on-resistance matching (≤1Ω at +5V).
Switching is controlled via 3-bit address decoding (A/B/C) and an active-high ENABLE input; all analog terminals tolerate voltages from GND to VCC, with internal ESD diodes clamping overvoltage conditions. Off-isolation exceeds –93dB and crosstalk remains below –96dB at 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V single supply - supports direct integration into 3.3V and 5V logic systems without level shifters |
| Turn-On Time (tON) | 15ns max at +5V - enables high-speed multiplexing in sampling systems up to ~30MHz effective bandwidth |
| On-Resistance (RON) | 10Ω max at +5V - minimizes signal attenuation and gain error in precision sensor interfaces |
| On-Resistance Match | 1Ω max between channels at +5V - critical for matched-path applications like differential signal switching |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance measurement nodes (e.g., pH sensors, piezoelectric pickups) |
| Off-Isolation | –93dB at 100kHz - suppresses unwanted coupling between inactive channels in multi-source A/V routing |
| Crosstalk | –96dB at 100kHz - maintains channel separation in simultaneous-signal environments like audio mixer backplanes |
Pinout & Package
MAX4619CUE+ is housed in a 16-pin TSSOP package (lead-free/RoHS-compliant), with 0.65mm pitch and exposed pad not internally connected. Pin layout follows industry-standard 74HC4053 pinout compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y1 (NO) | Normally open terminal of Y-channel SPDT switch - connects to common (Y) only when selected |
| 2 | Y0 (NC) | Normally closed terminal of Y-channel SPDT switch - connected to common (Y) unless Y1 is selected |
| 3 | Z1 (NO) | Normally open terminal of Z-channel SPDT switch - isolated until activated by address ABC = 111 |
| 4 | Z0 (NC) | Normally closed terminal of Z-channel SPDT switch - default path for Z common terminal |
| 5 | X1 (NO) | Normally open terminal of X-channel SPDT switch - selected when ABC = 001 |
| 6 | ENABLE | Active-high global enable - pulls all switches open when logic high; required for power-down mode |
| 7 | N.C. | No internal connection - must be left floating or tied to GND; no routing or loading impact |
| 8 | GND | Analog/digital ground reference - shared return for supply, logic, and signal paths |
| 9 | C | MSB address input - controls selection among four states per switch (0/1 for Z, X, Y) |
| 10 | B | Middle address bit - works with A and C to decode one of eight possible switch configurations |
| 11 | A | LSB address input - completes 3-bit binary selection for individual SPDT routing |
| 12 | X0 (NC) | Normally closed terminal of X-channel SPDT switch - default path for X common (X) |
| 13 | Y (COM) | Common terminal of Y-channel SPDT - bidirectional I/O node shared between Y0 and Y1 |
| 14 | X (COM) | Common terminal of X-channel SPDT - carries routed analog signal in either direction |
| 15 | Z (COM) | Common terminal of Z-channel SPDT - supports symmetrical signal routing without polarity constraints |
| 16 | VCC | Positive supply input - powers analog switches and digital logic; must be decoupled locally |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full VCC-to-GND voltage swing on all switch terminals - eliminates clipping in ±2.5V or unipolar 0–3.3V sensor interfaces |
| Guaranteed 1Ω RON match | Ensures <1% gain mismatch across channels - essential for calibrated multi-channel instrumentation front-ends |
| Low 3pC charge injection | Minimizes voltage glitch on high-Z nodes during switching - preserves integrity in sample-and-hold and ADC input stages |
| TTL/CMOS logic compatibility | Accepts 0.8V/2.4V thresholds at +5V supply - interoperates directly with microcontrollers and FPGAs without interface logic |
| Pin compatibility with 74HC4053 | Enables drop-in replacement in legacy designs using industry-standard triple SPDT layouts - no PCB rework needed |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4583CPE+ | Same 16-pin PDIP package; identical pinout and truth table; 25Ω RON max at +5V (vs. 10Ω for MAX4619CUE+) | Higher on-resistance limits use in <10kΩ impedance paths; better suited for general-purpose routing than precision measurement | Select MAX4583CPE+ when cost-sensitive PDIP assembly is required and 25Ω RON is acceptable |
| ADG1419BRUZ | 16-pin TSSOP; 0.7Ω RON max at +5V; higher 125°C operating range; requires dual supply (±15V or +12V) for full rail-to-rail swing | Superior RON match and lower distortion, but incompatible single-supply operation increases system complexity | Choose ADG1419BRUZ only when sub-1Ω matching and extended temperature range justify dual-supply design overhead |
Compared with MAX4583CPE+, MAX4619CUE+ offers 2.5× lower on-resistance for improved signal fidelity in low-impedance paths; versus ADG1419BRUZ, it simplifies power architecture with single-supply operation but trades off ultimate precision and temperature range.

FAQ
What is the maximum operating temperature range for MAX4619CUE+?
The MAX4619CUE+ is specified for operation from 0°C to +70°C ambient temperature. This commercial-grade temperature range aligns with its 'C' suffix designation and is validated per the device's Absolute Maximum Ratings and Electrical Characteristics tables. The part uses a BiCMOS process that maintains stable on-resistance and leakage performance across this range, with off-leakage rising to 10nA at +85°C - though that condition applies only to the extended-range 'E' variants like MAX4619EUE+.
Can MAX4619CUE+ operate from a +3.3V supply, and what performance changes occur?
Yes, MAX4619CUE+ operates from +3.3V (within its +2V to +5.5V range). At +3V supply, on-resistance increases to 20Ω max, turn-on time lengthens to 20ns max, and logic thresholds shift to 0.5V/2.0V - still compatible with standard 3.3V CMOS drivers. All other parameters including leakage, crosstalk, and off-isolation remain unchanged. This makes MAX4619CUE+ suitable for mixed-voltage systems where 3.3V logic coexists with 5V analog rails.
Is MAX4619CUE+ pin-compatible with the 74HC4053, and are there any layout considerations?
Yes, MAX4619CUE+ is fully pin-compatible with the 74HC4053 in TSSOP-16 packaging, sharing identical pin assignments for VCC, GND, ENABLE, A/B/C address lines, and all X/Y/Z COM/NO/NC terminals. Layout requires standard 0.65mm-pitch TSSOP footprints with thermal relief on VCC/GND pads; no special routing is needed beyond standard analog switch practices - including guard traces around sensitive analog nodes and local 100nF ceramic decoupling at VCC.
Does MAX4619CUE+ support bidirectional signal flow, and how does that affect circuit design?
Yes, MAX4619CUE+ supports fully bidirectional analog signal flow - all switch terminals (X, X0, X1, Y, Y0, Y1, Z, Z0, Z1) are functionally identical and interchangeable as inputs or outputs. This eliminates polarity constraints in AC-coupled paths and simplifies PCB layout for differential or floating sources. Designers may route signals from COM to NO/NC or vice versa without performance penalty, as on-resistance, capacitance, and distortion specs apply equally in both directions.
What is the purpose of the N.C. pin (Pin 7) on MAX4619CUE+, and how should it be handled?
Pin 7 on MAX4619CUE+ is designated N.C. (No Connection) and has no internal bond wire or circuit connection. It must be left electrically floating - neither tied to VCC nor GND - to avoid parasitic coupling or unintended current paths. In PCB layout, the pad may be omitted or retained for mechanical stability, but no trace or copper pour should connect to it. This pin serves only as a structural placeholder in the TSSOP-16 frame and carries zero electrical function in MAX4619CUE+ operation.
