Product details
Overview
MAX4783EUE+ from Maxim Integrated is a high-speed, low-voltage, triple SPDT CMOS analog switch configured for bidirectional rail-to-rail signal routing. It operates from +1.6V to +3.6V, delivers 0.7Ω on-resistance at +3V, 11ns turn-on time, and supports ±150mA continuous channel current in a 16-pin TSSOP package - ideal for battery-powered audio multiplexing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4783EUE+ datasheet, MAX4783EUE+ pinout, MAX4783EUE+ application, or MAX4783EUE+ equivalent, this page provides verified functional specifications, validated TSSOP pin mapping, confirmed SPDT switching behavior, and direct alternatives for space-constrained, low-RON, fast-switching analog signal path designs.
Technical Context
The MAX4783EUE+ implements three independent single-pole/double-throw (SPDT) switches using CMOS transmission-gate architecture, each controlled by a 3-bit binary address (A/B/C) and global ENABLE input. All switches share a common VCC/GND supply and support bidirectional analog signal flow with no polarity restriction.
Its logic interface is +1.8V CMOS-compatible (VIH = 1.4V min, VIL = 0.5V max at +3V supply), and internal ESD protection diodes clamp analog inputs to VCC and GND. Break-before-make timing is guaranteed at 2ns (typ) to prevent signal shorting during channel transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.7Ω at +3V supply - enables minimal voltage drop and power loss in precision analog paths carrying up to 150mA. |
| On-Resistance Match | 0.3Ω max between channels - ensures consistent gain/attenuation across multiple SPDT paths in differential or multi-channel systems. |
| Turn-On Time (tON) | 11ns typical - supports high-speed signal routing in sampling systems and digital audio switching applications. |
| Analog Signal Range | Rail-to-rail (0V to VCC) - allows full utilization of supply headroom for unipolar sensor or audio signals without level-shifting. |
| Supply Voltage Range | +1.6V to +3.6V - compatible with Li-ion, coin-cell, and low-power MCU I/O domains without external regulators. |
| Off-Isolation | -90dB at 1MHz - suppresses crosstalk between active and inactive SPDT paths in sensitive measurement or communication circuits. |
| Charge Injection | -110pC - limits voltage glitch on sampled-hold nodes, critical for ADC front-end multiplexing accuracy. |
Pinout & Package
MAX4783EUE+ uses a 16-pin TSSOP package (4.4mm × 5.0mm body, 0.65mm pitch) with exposed pad not connected internally. Pin numbering follows JEDEC MS-013AA standard, with Pin 1 marked by dot or bevel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Z1 | Normally open terminal of third SPDT switch - connects to Z when A/B/C select Z1 path. |
| 2 | Z0 | Normally closed terminal of third SPDT switch - connects to Z when A/B/C deselect Z1 path. |
| 3 | Z | Common output terminal of third SPDT switch - bidirectional signal path shared with Z0/Z1. |
| 4 | ENABLE | Global enable/disable control - logic high forces all three SPDT switches into high-impedance open state. |
| 5 | N.C. | No internal connection - must be left floating or tied to GND; no electrical function. |
| 6 | GND | Ground reference for analog and digital circuitry - requires low-impedance PCB connection for noise immunity. |
| 7 | C | MSB address input for SPDT selection - determines Z1/Z0 routing along with A and B. |
| 8 | B | Address bit for SPDT selection - used with A and C to decode one of eight possible switch states per SPDT. |
| 9 | A | LSB address input for SPDT selection - completes 3-bit binary decoding for channel selection. |
| 10 | X0 | Normally closed terminal of first SPDT switch - connects to X when address selects X0 path. |
| 11 | X1 | Normally open terminal of first SPDT switch - connects to X when address selects X1 path. |
| 12 | X | Common output terminal of first SPDT switch - bidirectional signal path shared with X0/X1. |
| 13 | Y | Common output terminal of second SPDT switch - bidirectional signal path shared with Y0/Y1. |
| 14 | Y0 | Normally closed terminal of second SPDT switch - connects to Y when address selects Y0 path. |
| 15 | Y1 | Normally open terminal of second SPDT switch - connects to Y when address selects Y1 path. |
| 16 | VCC | Positive supply for analog switches and logic - must be decoupled with 0.1µF ceramic capacitor near pin. |
Key Features
| Feature | Design Value |

| +1.8V CMOS logic compatibility | Direct interfacing with low-voltage microcontrollers (e.g., ARM Cortex-M0+, MSP430) without level shifters. |
| 0.1Ω RON flatness | Maintains linear transfer characteristics across full analog input range - essential for precision instrumentation and audio fidelity. |
| Break-before-make timing | 2ns guaranteed interval prevents momentary short-circuit between X0/X1, Y0/Y1, or Z0/Z1 during switching transitions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4783ETE+ | Identical electrical specs but in 3mm × 3mm thin QFN package - 60% smaller footprint, better thermal performance, no leaded pins. | Suitable for ultra-compact PCBs where TSSOP height or solder joint reliability is a concern. | Select MAX4783ETE+ when board space or thermal management outweighs hand-soldering convenience. |
| ADG783BRUZ | 0.8Ω RON, 13ns tON, +1.8V to +5.5V supply - wider voltage range but slightly higher RON and slower switching. | Preferred in mixed-supply systems (e.g., +3.3V logic with +5V analog rails) where MAX4783EUE+ cannot operate above +3.6V. | Choose ADG783BRUZ only if system requires >+3.6V operation or dual-supply flexibility; otherwise MAX4783EUE+ offers superior speed and RON. |
Compared with MAX4783ETE+ and ADG783BRUZ, MAX4783EUE+ provides the fastest switching (11ns), lowest on-resistance (0.7Ω), and lowest supply voltage floor (1.6V), making it optimal for compact, battery-powered, high-fidelity analog routing where TSSOP assembly is acceptable.

FAQ
What is the maximum analog signal voltage range supported by the MAX4783EUE+?
The MAX4783EUE+ supports rail-to-rail analog signals from 0V to VCC. With a +3.6V maximum supply, this means signals up to +3.6V can pass through any channel without clipping or distortion - critical for preserving dynamic range in audio and sensor interfaces where level-shifting is undesirable.
Does the MAX4783EUE+ require external pull-up or pull-down resistors on its address pins (A, B, C)?
No. The MAX4783EUE+ has CMOS-compatible digital inputs with defined VIH (≥1.4V) and VIL (≤0.5V) thresholds at +3V supply. Address pins A, B, and C may be driven directly from microcontroller GPIOs without external biasing - provided the driving source meets voltage and current specs outlined in the MAX4783EUE+ datasheet.
Can the MAX4783EUE+ be used with a +1.8V supply, and how does performance change?
Yes, the MAX4783EUE+ operates down to +1.6V. At +1.8V, on-resistance increases to 1.6Ω (typ), turn-on time extends to 17ns (typ), and logic thresholds adjust to VIH ≥1.0V/VIL ≤0.4V. These shifts are fully characterized and guaranteed - enabling reliable use in ultra-low-power modes where +3V operation is unavailable.
Is the ENABLE pin active-high or active-low, and what happens when it is left unconnected?
The ENABLE pin on the MAX4783EUE+ is active-high: logic high disables all three SPDT switches (open state), logic low enables normal address-controlled switching. If left unconnected, ENABLE floats near VCC due to internal leakage and may cause unpredictable behavior - it must be actively driven or pulled low via a resistor to ensure reliable operation.
How does the MAX4783EUE+ compare to the MAX4781EUE+ in terms of channel configuration and use cases?
The MAX4783EUE+ integrates three independent SPDT switches, whereas the MAX4781EUE+ is an 8:1 analog multiplexer. This makes MAX4783EUE+ ideal for parallel signal routing (e.g., stereo audio + auxiliary path), while MAX4781EUE+ suits sequential sampling of multiple sensors. Their pinouts differ significantly - they are not functionally interchangeable despite shared package and voltage specs.
