Product details
Overview
MAX4619EUE+ from Analog Devices is a high-speed, low-voltage CMOS triple SPDT analog switch configured for signal routing in precision, bidirectional, rail-to-rail applications. It operates from a single +2V to +5.5V supply, delivers 15ns tON/10ns tOFF, guarantees ≤10Ω on-resistance at +5V, and maintains ≤1nA off-leakage at +25°C - enabling use in battery-powered audio/video multiplexing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4619EUE+ datasheet, MAX4619EUE+ pinout, MAX4619EUE+ application, or MAX4619EUE+ equivalent, key selection criteria include its guaranteed 1Ω on-resistance match between channels, -93dB off-isolation at 100kHz, 8.5pF output off-capacitance, and compatibility with TTL/CMOS logic under +5V supply - all critical for low-distortion, high-channel-density analog switching.
Technical Context
The MAX4619EUE+ implements three independent SPDT switches using BiCMOS process technology, each with matched P- and N-channel MOSFETs to ensure rail-to-rail analog signal handling (0V to VCC) and symmetrical on-resistance flatness. Its digital control interface uses address inputs A/B/C and a global ENABLE pin, supporting break-before-make switching with <1.5ns tBBM to prevent signal shorting during channel transitions.
All analog terminals feature internal ESD protection diodes to VCC and GND, limiting analog input voltage to -0.3V to (VCC + 0.3V). Logic thresholds scale with VCC: 2.4V/0.8V at +5V, 2.0V/0.5V at +3.3V - ensuring robust interfacing across supply voltages without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +5.5V single supply - supports direct integration into 2.5V, 3.3V, and 5V systems without regulators. |
| On-Resistance (RON) | ≤10Ω max at +5V - ensures minimal signal attenuation and gain error in 600Ω audio or sensor interfaces. |
| RON Match | ≤1Ω max between channels at +5V - preserves amplitude consistency across switched paths in multi-channel instrumentation. |
| tON/tOFF | 15ns/10ns typical - enables >30MHz switching rates for time-division multiplexed data acquisition. |
| Off-Leakage Current | ≤1nA at +25°C - prevents DC offset drift in high-impedance sensor front-ends (e.g., thermocouples, pH electrodes). |
| Off-Isolation | -93dB at 100kHz - suppresses crosstalk between active and inactive channels in dense PCB layouts. |
| Output Off-Capacitance | 8.5pF - minimizes high-frequency feedthrough and preserves bandwidth in RF-adjacent analog routing. |
Pinout & Package
MAX4619EUE+ is housed in a 16-pin TSSOP package (JEDEC MO-153, 4.4mm × 5mm body, 0.65mm pitch), optimized for space-constrained industrial and portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y1 | Normally open input of Y-switch - connects to common Y terminal when selected via A/B/C logic. |
| 2 | Y0 | Normally closed input of Y-switch - default path for Y-switch unless overridden by address inputs. |
| 3 | X1 | Normally open input of X-switch - active when A=0, B=0, C=1 per truth table. |
| 4 | Z | Common output of Z-switch - bidirectional node shared with Z0/Z1 paths. |
| 5 | Z0 | Normally closed input of Z-switch - provides default connection to Z common terminal. |
| 6 | ENABLE | Global enable/disable control - logic high forces all switches open (high-Z state), independent of address inputs. |
| 7 | N.C. | No internal connection - must be left floating or grounded; no electrical function. |
| 8 | GND | Analog/digital reference ground - shared return for supply, logic, and signal paths; requires low-impedance layout. |
| 9 | C | Most significant address bit - selects between Z0/Z1 and determines X/Y channel group in 3-bit decode. |
| 10 | B | Middle address bit - combines with A/C to select one of eight possible switch states per SPDT section. |
| 11 | A | Least significant address bit - completes 3-bit decoding for precise channel selection across X/Y/Z banks. |
| 12 | X0 | Normally closed input of X-switch - default path for X-switch; complements X1 as SPDT pair. |
| 13 | Y | Common output of Y-switch - bidirectional node routed to Y0/Y1 based on address state. |
| 14 | X | Common output of X-switch - primary analog I/O node for X-switch bank; interchangeable as input/output. |
| 15 | Z1 | Normally open input of Z-switch - activated only when C=1, A=0, B=0 per truth table. |
| 16 | VCC | Positive supply - powers internal logic and switch FETs; also sets analog signal range (0V to VCC). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports 0V to VCC signals without clipping - essential for unipolar sensor outputs and audio line-level routing. |
| Guaranteed 1Ω RON match | Ensures ≤0.1% gain error between parallel signal paths - critical for differential or ratiometric measurement systems. |
| Low charge injection (3pC) | Minimizes voltage glitch on high-impedance nodes during switching - preserves accuracy in sample-and-hold circuits. |
| TTL/CMOS logic compatibility | Eliminates need for external level shifters when interfacing with microcontrollers or FPGAs operating at +5V. |
| Pin-compatible with 74HC4053 | Enables drop-in replacement in legacy designs using industry-standard 3-channel SPDT logic, reducing redesign effort. |

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 |
|---|---|---|---|
| MAX4583ESE+ | Same BiCMOS process, identical pinout, but rated only for 0°C to +70°C operation and higher 15Ω RON at +5V. | Suitable for commercial-grade equipment where extended temperature range is not required. | Select MAX4583ESE+ only if ambient operating temperature stays within 0°C–70°C and 5Ω higher RON is acceptable. |
| ADG1419BRUZ | Higher 1.8Ω RON match, 12ns tON, but requires dual ±15V supplies or +12V single supply - incompatible with +2V–+5.5V operation. | Targeted at high-voltage test equipment, not low-voltage portable systems. | Choose ADG1419BRUZ only when bipolar supply capability and sub-1Ω RON match outweigh the need for ultra-low-voltage operation. |
Compared with MAX4583ESE+, MAX4619EUE+ offers wider -40°C to +85°C operation and lower on-resistance; versus ADG1419BRUZ, it enables true single-supply battery operation but trades off ultimate RON precision for voltage flexibility.

FAQ
What is the maximum analog signal voltage range supported by the MAX4619EUE+?
The MAX4619EUE+ supports rail-to-rail analog signals from 0V to VCC. With VCC = +5.5V, the absolute maximum analog input is +5.8V (VCC + 0.3V) due to internal ESD diode clamping. Exceeding this risks forward-biasing protection diodes and increasing leakage. The MAX4619EUE+ does not support negative analog voltages unless a negative supply is applied to VEE - which this device lacks.
Does the MAX4619EUE+ require external pull-up or pull-down resistors on its digital control pins?
No, the MAX4619EUE+ does not require external pull-up or pull-down resistors on A, B, C, or ENABLE pins. Its digital inputs have guaranteed TTL/CMOS-compatible thresholds (e.g., 2.4V/0.8V at +5V supply) and draw only ±1µA input current. However, ENABLE should be actively driven - leaving it floating may result in undefined switch states and increased ICC.
Can the MAX4619EUE+ be used to switch differential analog signals?
Yes, the MAX4619EUE+ can switch differential signals by using two matched SPDT sections (e.g., X and Y) with identical control logic. Its guaranteed ≤1Ω RON match and -96dB crosstalk preserve common-mode rejection. However, differential pairs must be routed with tight length matching, and the 8.5pF output off-capacitance requires careful layout to avoid skew above 10MHz.
What is the thermal performance of the MAX4619EUE+ in TSSOP package at full load?
In its 16-pin TSSOP package, the MAX4619EUE+ has a thermal resistance θJA of 106°C/W. At maximum continuous power dissipation (755mW at +70°C ambient), junction temperature reaches ~145°C - exceeding recommended limits. For reliable operation, keep total power below 300mW (e.g., <10mA per channel at 5V) or add copper pour to reduce θJA to ~60°C/W.
How does the MAX4619EUE+ handle overvoltage conditions on analog inputs?
The MAX4619EUE+ features internal ESD diodes from each analog pin to VCC and GND. If an analog signal exceeds VCC or drops below GND, the corresponding diode conducts, limiting voltage excursion to ±0.3V beyond rails. Sustained overvoltage (>±75mA) risks damage; external series resistors (e.g., 100Ω) are recommended for fault protection in harsh environments.
