Product details
Overview
MAX4619CSE+T from Analog Devices is a high-speed, low-voltage CMOS triple SPDT analog switch IC operating from a single +2V to +5.5V supply, delivering 15ns turn-on time, 10ns turn-off time, and ≤10Ω on-resistance at +5V - ideal for precision audio/video signal routing in battery-powered instrumentation.
For engineers reviewing the MAX4619CSE+T datasheet, MAX4619CSE+T pinout, MAX4619CSE+T application, or MAX4619CSE+T equivalent, this device offers rail-to-rail analog signal handling, guaranteed 1Ω on-resistance matching between channels, <0.017% THD at 600Ω, and TTL/CMOS logic compatibility with +5V supply - critical for low-distortion multiplexing in portable test equipment and communications interfaces.
Technical Context
The MAX4619CSE+T implements three independent SPDT switches controlled by address inputs A/B/C and a global ENABLE pin, supporting break-before-make switching with <1.5ns transition time and no overlap-induced signal shorting. Each switch features matched internal FETs and ESD-protected analog terminals referenced to VCC and GND.
Its BiCMOS process enables simultaneous low on-resistance (≤10Ω @ +5V), ultra-low leakage (1nA off-leakage @ +25°C), and high-frequency performance up to 50MHz in 50Ω systems - with off-isolation of –93dB and crosstalk suppression of –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 domains without level shifters. |
| On-Resistance (RON) | ≤10Ω max at +5V - ensures minimal voltage drop and signal attenuation in precision sensor or audio paths. |
| On-Resistance Match | ≤1Ω max between channels at +5V - preserves amplitude consistency across switched signals in multi-channel acquisition. |
| Switching Speed | tON = 15ns, tOFF = 10ns - enables reliable sampling of fast analog transients in data-acquisition front-ends. |
| Off-Leakage Current | 1nA max at +25°C - prevents DC error accumulation in high-impedance sensor interfaces (e.g., thermocouples, pH electrodes). |
| Analog Signal Range | Rail-to-rail (0V to VCC) - allows full utilization of ADC input range without external biasing. |
| THD | <0.017% at 600Ω load - maintains fidelity in line-level audio routing and instrumentation amplifier signal chains. |
Pinout & Package
MAX4619CSE+T is housed in a 16-pin narrow SO (Small Outline) package, RoHS-compliant and tape-and-reel packaged (+T suffix). Pin pitch is 0.050", body width 0.150", and thermal resistance θJA = 8.70mW/°C above +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y1 | "Y" switch normally open analog terminal - connects to Y output when selected via address A/B/C. |
| 2 | Y0 | "Y" switch normally closed analog terminal - default path for Y channel when unselected. |
| 3 | Z1 | "Z" switch normally open analog terminal - active path for Z channel under specific address state. |
| 4 | Z | "Z" common analog terminal - shared I/O node for Z SPDT switch. |
| 5 | Z0 | "Z" switch normally closed analog terminal - default return path for Z channel. |
| 6 | ENABLE | Digital enable input - logic high disables all three SPDT switches; tied to GND for always-on operation. |
| 7 | N.C. | No internal connection - must remain unconnected per datasheet; no pull-up/down required. |
| 8 | GND | Analog/digital ground reference - common return for VCC, logic, and analog signals. |
| 9 | C | MSB address input - selects among eight possible switch states (with A/B) per SPDT group. |
| 10 | B | Address bit - used with A and C to decode which SPDT channel pair is activated. |
| 11 | A | LSB address input - completes 3-bit selection for X/Y/Z switch configuration per truth table. |
| 12 | X0 | "X" switch normally closed analog terminal - default path for X channel. |
| 13 | X1 | "X" switch normally open analog terminal - alternate path for X channel under address control. |
| 14 | X | "X" common analog terminal - bidirectional I/O node for X SPDT switch. |
| 15 | Y | "Y" common analog terminal - bidirectional I/O node for Y SPDT switch. |
| 16 | VCC | Positive supply - powers internal logic and analog switches; also sets analog signal ceiling (0V to VCC). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4583CSE+ | Same pinout, but higher RON (15Ω max @ +5V) and slower switching (tON = 25ns); no guaranteed RON match spec. | Acceptable where 5Ω higher on-resistance and 10ns slower speed are tolerable in non-critical signal paths. | Choose MAX4583CSE+ only if legacy design uses it and MAX4619CSE+T's tighter RON match is unnecessary. |
| 74HC4053D,653 | Industry-standard 16-pin SO, but higher RON (120Ω @ +4.5V), no guaranteed RON match, and no 2V operation support. | Suitable for digital-control analog routing in cost-sensitive consumer gear where precision is secondary. | Select 74HC4053D,653 only for non-precision, high-volume applications requiring lowest BOM cost over performance. |
Compared with MAX4583CSE+ and 74HC4053D,653, the MAX4619CSE+T delivers superior on-resistance matching (≤1Ω vs. unspecified), lower leakage (1nA vs. 100nA), and wider supply range (+2V to +5.5V), making it optimal for precision portable instrumentation where signal fidelity and battery efficiency are prioritized.

FAQ
What is the maximum operating supply voltage for MAX4619CSE+T?
The MAX4619CSE+T supports a single-supply range from +2V to +5.5V. Operation beyond +5.5V violates absolute maximum ratings and risks permanent damage. At +5.5V, analog signal range remains rail-to-rail (0V to +5.5V), and all electrical specifications - including on-resistance and leakage - are guaranteed per datasheet conditions.
Does MAX4619CSE+T support bidirectional signal flow?
Yes, the MAX4619CSE+T supports fully bidirectional analog signal routing. All analog terminals (X, Y, Z, X0/X1, Y0/Y1, Z0/Z1) are interchangeable as inputs or outputs. This is explicitly confirmed in the Applications Information section: "Input and output pins are identical and interchangeable. Any may be considered an input or output; signals pass equally well in both directions."
What is the guaranteed on-resistance match between channels for MAX4619CSE+T?
The MAX4619CSE+T guarantees ≤1Ω on-resistance match (ΔRON) between any two channels when operated at +5V supply and TA = +25°C, as specified in the Electrical Characteristics table. This match holds across the full analog signal range (0V to VCC) and is critical for applications requiring amplitude consistency, such as differential signal switching or ratiometric sensor readouts.
Can MAX4619CSE+T operate from a +3.3V supply?
Yes, the MAX4619CSE+T is fully specified for +3.3V operation. At VCC = +3V to +3.6V, it delivers ≤20Ω max on-resistance, 1nA max off-leakage at +25°C, and switching times of 20ns tON / 15ns tOFF. Logic thresholds automatically scale to 2.0V (VIH min) and 0.5V (VIL max), ensuring reliable interface with 3.3V microcontrollers without level shifters.
Is MAX4619CSE+T pin-compatible with the 74HC4053?
Yes, the MAX4619CSE+T is pin-compatible with the industry-standard 74HC4053 in 16-pin narrow SO packages. Pin functions, layout, and truth table behavior match exactly - though MAX4619CSE+T offers superior performance: 10× lower on-resistance, 100× lower leakage, and 5× faster switching. No PCB changes are required for drop-in replacement where enhanced specs are beneficial.
