Product details
Overview
MAX4619CSE 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.
For engineers reviewing the MAX4619CSE datasheet, MAX4619CSE pinout, MAX4619CSE application, or MAX4619CSE equivalent, this page provides verified functional specifications, validated package mapping (16-pin narrow SO), confirmed SPDT topology, and two rigorously cross-referenced alternative parts for system-level design continuity.
Technical Context
The MAX4619CSE implements three independent single-pole/double-throw (SPDT) switches using BiCMOS process technology, each with rail-to-rail analog signal handling and TTL/CMOS-compatible digital control inputs (A, B, C, ENABLE). Its logic thresholds scale with VCC: 2.4V min high / 0.8V max low at +5V, 2.0V / 0.5V at +3V.
Each SPDT channel features matched on-resistance (≤1Ω max difference between normally open and normally closed paths at +5V), low charge injection (3pC), and high off-isolation (–93dB at 100kHz), making it suitable for precision multiplexing where signal integrity and crosstalk suppression are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Triple SPDT analog switch - enables independent selection of two analog paths per channel (X/Y/Z) |
| Supply Range | +2V to +5.5V single supply - supports battery-powered and low-voltage embedded systems without dual-rail generation |
| tON/tOFF | 15ns / 10ns at +5V - ensures minimal signal disruption in high-speed sampling and real-time routing |
| RON (max) | 10Ω at +5V, 20Ω at +3V - maintains low insertion loss and preserves signal fidelity in 600Ω audio and sensor interfaces |
| Off-Leakage (25°C) | 1nA per channel - prevents DC error accumulation in high-impedance sensor front-ends and precision ADC multiplexers |
| Off-Isolation | –93dB at 100kHz - suppresses inter-channel coupling in multi-source A/V routing and communication signal switching |
| Crosstalk | –96dB at 100kHz - minimizes interference between active and inactive channels in dense PCB layouts |
Pinout & Package
MAX4619CSE is housed in a 16-pin narrow SO (Small Outline) package, RoHS-compliant, with 1.27mm pitch and standard JEDEC MO-153 footprint. Pin 1 is located at the top-left corner adjacent to the index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y1 | Y-channel normally open analog terminal - connects to Y output when selected |
| 2 | Y0 | Y-channel normally closed analog terminal - connects to Y output by default |
| 3 | Z1 | Z-channel normally open analog terminal - connects to Z output when selected |
| 4 | Z0 | Z-channel normally closed analog terminal - connects to Z output by default |
| 5 | X1 | X-channel normally open analog terminal - connects to X output when selected |
| 6 | ENABLE | Digital enable input - logic high disables all three SPDT switches; tied low for normal operation |
| 7 | N.C. | No internal connection - must remain unconnected; no routing or grounding required |
| 8 | GND | Analog and digital ground reference - common return for VCC, signals, and logic inputs |
| 9 | C | Address bit C - selects between Z0/Z1 and Y0/Y1 pairs in conjunction with A/B |
| 10 | B | Address bit B - determines channel pair selection with A and C for full 3-bit decoding |
| 11 | A | Address bit A - least-significant address input controlling SPDT state per truth table |
| 12 | X0 | X-channel normally closed analog terminal - connects to X output by default |
| 13 | Y | Y-channel common analog terminal - bidirectional I/O shared with Y0/Y1 |
| 14 | X | X-channel common analog terminal - bidirectional I/O shared with X0/X1 |
| 15 | Z | Z-channel common analog terminal - bidirectional I/O shared with Z0/Z1 |
| 16 | VCC | Positive supply input - powers analog switches and digital logic; must be decoupled near pin |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible replacement | Direct drop-in for 74HC4053 and MAX4583 - eliminates PCB redesign in legacy analog mux upgrades |

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, identical SPDT architecture, but higher RON (15Ω @ +5V) and slower tON/tOFF (25ns/15ns) | Acceptable where speed and on-resistance margins exceed 15ns/15Ω requirements | Select MAX4583CSE+ only if legacy stock exists or cost sensitivity outweighs performance needs |
| 74HC4053PW,118 | Industry-standard 74HC logic family; lower drive strength, no guaranteed RON match, wider VCC range (2–10V) | Suitable for non-critical digital-control analog routing where precision matching is unnecessary | Choose 74HC4053PW,118 for cost-sensitive consumer designs with relaxed THD and leakage specs |
Compared with MAX4583CSE+ and 74HC4053PW,118, the MAX4619CSE offers superior speed (15ns vs. 25ns/35ns), tighter RON matching (≤1Ω vs. unspecified), and lower THD (<0.017% vs. >0.1%), making it optimal for precision instrumentation and high-fidelity audio routing.

FAQ
What is the maximum operating voltage for MAX4619CSE?
The MAX4619CSE supports a single-supply operating range from +2V to +5.5V. Absolute maximum ratings specify –0.3V to +6V on VCC and digital inputs, but continuous operation above +5.5V risks permanent damage. Operation at +2.5V is functional but increases on-resistance significantly (up to 60Ω), so +3V or higher is recommended for most applications.
Does MAX4619CSE support bidirectional signal flow?
Yes, the MAX4619CSE supports fully bidirectional analog signal routing. Each SPDT channel (X, Y, Z) has interchangeable common (X/Y/Z), normally closed (X0/Y0/Z0), and normally open (X1/Y1/Z1) terminals - all pins are electrically symmetric with identical RON, leakage, and capacitance characteristics regardless of signal direction.
How does the ENABLE pin function on MAX4619CSE?
The ENABLE pin (Pin 6) is an active-high digital control input. When driven logic high, it forces all three SPDT switches into the high-impedance off-state regardless of address inputs A/B/C. When held low (or grounded), the switches respond to A/B/C address states per the truth table. No external pull-down is required, but tying to GND ensures default enabled operation.
What is the thermal performance of MAX4619CSE in narrow SO package?
In its 16-pin narrow SO package, the MAX4619CSE has a thermal resistance θJA of 115°C/W and a maximum continuous power dissipation of 696mW at +70°C ambient. Derating is 8.70mW/°C above +70°C. For sustained +85°C operation, power dissipation must remain below ~550mW to avoid exceeding the +150°C storage limit.
Can MAX4619CSE replace MAX4619CPE+T in the same PCB layout?
Yes - MAX4619CSE and MAX4619CPE+T share identical pinout, electrical specifications, and logic behavior. The only difference is package type: narrow SO (S16+3) versus plastic DIP (P16+1). Footprint and soldering processes differ, but signal routing, bypassing, and control logic remain fully compatible across both variants.
