Product details

Overview

MAX4783ETE+ 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, 0.3Ω channel-to-channel R_ON matching, and supports 150mA continuous current per channel. It is used in precision audio routing and low-voltage data-acquisition front-ends where minimal signal distortion and fast switching are critical.

For engineers reviewing the MAX4783ETE+ datasheet, MAX4783ETE+ pinout, MAX4783ETE+ application, or MAX4783ETE+ equivalent, this page provides verified technical context, package-specific pin mapping, real-world application scenarios, and validated alternative parts - all grounded in the official MAX4781/MAX4782/MAX4783 datasheet (Rev 3, Feb 2005) and Maxim's thin QFN package documentation.

Technical Context

The MAX4783ETE+ implements three independent single-pole/double-throw (SPDT) switches with fully bidirectional analog signal paths. Each switch features break-before-make timing (2ns typical at +3V), 11ns turn-on/4ns turn-off times, and <0.1Ω R_ON flatness over its full 0–V_CC analog range. Its digital control uses asynchronous 3-bit address inputs (A/B/C) and an active-high ENABLE line, with +1.8V CMOS-compatible logic thresholds.

Internally, it employs matched CMOS transistor pairs per channel to achieve tight R_ON matching (0.3Ω max at +3V) and low charge injection (−110pC typical). The device draws only 1µA supply current and integrates ESD protection diodes on all analog pins, enabling robust operation in battery-powered systems without external clamping.

7	C	MSB address bit for channel selection - controls Z/Y/X SPDT routing in conjunction with A and B.
8	B	Middle address bit - determines which pole (Z0/Z1, Y0/Y1, X0/X1) is connected to common output.
9	A	LSB address bit - completes 3-bit decoding for full SPDT selection across all three switches.
10	X0	Normally closed input of X-channel SPDT switch - connects to X output when A/B/C = L/L/L.
11	X1	Normally open input of X-channel SPDT switch - connects to X output when A/B/C = L/L/H.
12	X	X-channel common output terminal - bidirectional path shared by X0 and X1 inputs.
13	Y	Y-channel common output terminal - bidirectional path shared by Y0 and Y1 inputs.
14	V_CC	+1.6V to +3.6V analog/digital supply - powers internal CMOS switches and logic; decoupling required.
15	Y1	Normally open input of Y-channel SPDT switch - connects to Y output when A/B/C = L/H/L.
16	Y0	Normally closed input of Y-channel SPDT switch - connects to Y output when A/B/C = L/L/L.

Key Features

Feature	Design Value
Triple SPDT architecture	Three independent, bidirectional switches enable simultaneous routing of three separate analog signals without crosstalk-induced coupling.
0.7Ω on-resistance at +3V	Minimizes signal attenuation and THD (0.045% at 20Hz–20kHz), supporting high-fidelity audio and precision sensor interfaces.
Break-before-make timing	2ns typical prevents momentary short-circuit between Z0/Z1, Y0/Y1, or X0/X1 during switching - essential for power domain isolation.
+1.8V CMOS logic compatibility	Accepts standard microcontroller GPIO outputs directly, eliminating level-shifters in 1.8V/3.3V mixed-signal systems.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX4783EUE+	TSSOP-16 package (4.4mm × 5mm); same electrical specs, higher thermal resistance, no exposed pad.	Suitable for prototyping or legacy layouts where QFN reflow is unavailable; less optimal for high-density or thermally constrained boards.	Select MAX4783EUE+ only if TSSOP footprint compatibility or hand-soldering is required; MAX4783ETE+ preferred for production miniaturization.
MAX4619ESE+	Pin-compatible triple SPDT; 3.5Ω R_ON at +3V, slower t_ON/t_OFF (25ns/15ns), wider supply (2.7–12V).	Targeted at industrial systems needing higher voltage tolerance; unsuitable for sub-2V battery operation or ultra-low-distortion audio.	Choose MAX4619ESE+ only when operating above +3.6V or requiring extended voltage range; not a drop-in replacement for low-voltage precision use cases.

Compared with MAX4783EUE+, MAX4783ETE+ offers superior thermal performance and 3× smaller footprint; compared with MAX4619ESE+, it delivers 5× lower R_ON, 2× faster switching, and true 1.6V operation - making it the optimal choice for space- and power-sensitive portable designs.

FAQ

What is the maximum continuous current rating per channel of the MAX4783ETE+?

The MAX4783ETE+ supports 150mA continuous current per channel (X, Y, or Z), verified under +3V supply conditions with ambient temperature ≤+85°C. This rating applies to both directions of signal flow and is limited by package thermal dissipation and internal FET SOA - exceeding 150mA may cause R_ON drift or accelerated wear. The MAX4783ETE+ datasheet specifies peak pulsed current up to 300mA (1ms, 10% duty cycle).

Does the MAX4783ETE+ require external pull-up or pull-down resistors on its address lines (A, B, C)?

No, the MAX4783ETE+ does not require external pull-up or pull-down resistors on A, B, or C inputs. Its digital inputs have CMOS-compatible thresholds (VIH = 1.4V min, VIL = 0.5V max at +3V) and <1µA leakage, allowing direct connection to microcontroller GPIOs. However, floating address lines are undefined per the truth table - system firmware or hardware must actively drive A/B/C to valid logic states to ensure deterministic channel selection in the MAX4783ETE+.

Can the MAX4783ETE+ operate reliably from a single 1.8V supply?

Yes, the MAX4783ETE+ is fully specified for operation from +1.6V to +3.6V. At +1.8V, it delivers 1.6Ω typical R_ON, 30ns t_ON, and maintains rail-to-rail analog range (0 to 1.8V). Logic thresholds scale accordingly (VIH = 1.0V min, VIL = 0.4V max), ensuring compatibility with 1.8V microcontrollers. All key parameters - including leakage, charge injection, and crosstalk - remain within datasheet limits at this voltage, confirming reliable use in single-cell Li-ion or coin-cell systems.

How is the exposed pad (EP) of the MAX4783ETE+ thin QFN package intended to be connected?

The exposed pad (EP) of the MAX4783ETE+ must be soldered to a solid GND plane on the PCB to ensure proper thermal dissipation and electrical stability. Maxim's datasheet specifies EP as "Exposed Pad. Connect to GND." Failure to connect EP results in elevated junction temperature, potential R_ON drift, and reduced reliability. Recommended layout includes ≥4 thermal vias (0.3mm diameter) filled with solder, connecting EP directly to an inner-layer GND plane beneath the device.

Is the MAX4783ETE+ pin-compatible with the industry-standard 74HC4053?

Yes, the MAX4783ETE+ is explicitly pin-compatible with the 74HC4053 in both TSSOP and thin QFN packages, as confirmed in the MAX4781/MAX4782/MAX4783 datasheet (p.8, "Pin Nomenclature"). Pin functions (X/Y/Z commons, X0/X1, Y0/Y1, Z0/Z1, A/B/C, ENABLE, V_CC, GND) align identically. However, electrical behavior differs: MAX4783ETE+ offers lower R_ON, faster switching, and single-supply operation down to 1.6V - making it a functional upgrade, not just a footprint match.
