Product details
Overview
MAX4783ETE+T 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 RON 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+T datasheet, MAX4783ETE+T pinout, MAX4783ETE+T application, or MAX4783ETE+T equivalent, this page provides verified electrical parameters, thin QFN package details, truth-table–driven SPDT control logic, and validated alternatives for battery-powered and space-constrained analog signal path designs.
Technical Context
The MAX4783ETE+T implements three independent single-pole/double-throw (SPDT) switches using CMOS transmission-gate architecture with matched P/N transistor pairs. Each switch features break-before-make timing (1–2ns), <110pC charge injection, and rail-to-rail analog signal handling across its full ±0.3V to VCC+0.3V input range.
Control is implemented via three address inputs (A, B, C) and a global ENABLE pin, supporting eight discrete switch states per SPDT section. The device uses +1.8V CMOS-compatible logic thresholds (VIH = 1.4V min at +3V supply) and draws only 1µA quiescent supply current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.7Ω at +3V supply - ensures minimal voltage drop and power loss in 150mA signal paths |
| RON Matching | 0.3Ω max between channels - preserves gain/phase balance in differential or multi-path routing |
| Turn-On/Off Time | tON = 11ns, tOFF = 4ns - enables clean switching in >50MHz analog systems |
| Analog Signal Range | Rail-to-rail (0V to VCC) - supports full-scale signals without clipping in single-supply systems |
| Supply Voltage Range | +1.6V to +3.6V - compatible with Li-ion, coin-cell, and low-power MCU I/O domains |
| Charge Injection | −110pC - limits glitch-induced error in precision sample-and-hold or ADC front-end applications |
| Off-Isolation | −90dB at 1MHz - suppresses crosstalk between active and inactive SPDT paths |
Pinout & Package
MAX4783ETE+T is housed in a 3mm × 3mm, 16-pin thin QFN package with exposed thermal pad (EP) connected to GND. The package supports reflow soldering and provides low-inductance grounding for high-frequency analog integrity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4619ESE+ | Same 3×SPDT topology, but 16-pin SO package; RON = 1.5Ω at +3V (vs. 0.7Ω); tON/tOFF = 25ns/15ns | Higher RON and slower switching limit use in high-fidelity audio or >10MSPS DAQ | Select when board layout requires SOIC footprint or thermal constraints preclude QFN |
| TMUX1574RTER | 3×SPDT, 0.5Ω RON, but requires ≥1.8V logic and has no ENABLE pin; different pinout (non-pin-compatible) | Lacks global disable function and differs in address decoding - requires firmware adaptation | Select for lowest RON in new designs where ENABLE is not required and layout can accommodate revised pin mapping |
Compared with MAX4783ETE+T, MAX4619ESE+ trades performance for legacy package compatibility, while TMUX1574RTER improves conduction loss but removes system-level control flexibility - choice depends on whether PCB footprint, switching speed, or functional completeness dominates the design priority.

FAQ
What is the maximum continuous current rating per channel of the MAX4783ETE+T?
The MAX4783ETE+T supports 150mA continuous current per SPDT channel, verified across the full operating temperature range (−40°C to +85°C) and supply voltage range (+1.6V to +3.6V). This rating applies to both normally open (X1/Y1/Z1) and normally closed (X0/Y0/Z0) terminals when used within absolute maximum voltage limits.
Does the MAX4783ETE+T support rail-to-rail analog signal operation?
Yes, the MAX4783ETE+T supports true rail-to-rail analog signal operation - inputs and outputs can swing from 0V to VCC with no degradation in on-resistance or distortion. This capability is maintained across its entire +1.6V to +3.6V supply range and is confirmed in the Electrical Characteristics table under "Analog Signal Range".
How does the ENABLE pin function on the MAX4783ETE+T?
The ENABLE pin on the MAX4783ETE+T is an active-high global control: when driven logic high, it forces all three SPDT sections into the open (high-impedance) state regardless of address inputs A/B/C. When held low or grounded, normal address-controlled switching resumes. Its VIH threshold is 1.4V min at +3V supply, ensuring compatibility with +1.8V CMOS logic.
Is the MAX4783ETE+T pin-compatible with industry-standard analog switches?
The MAX4783ETE+T is pin-compatible with the 74HC4053 and MAX4619 in TSSOP-16, but not in its thin QFN-16 package. The MAX4783ETE+T QFN pinout differs from those legacy packages - users migrating from TSSOP must redesign the footprint. Pin compatibility applies only to the MAX4783EUE (TSSOP) variant, not the MAX4783ETE+T.
What is the typical charge injection value for the MAX4783ETE+T, and why does it matter?
The MAX4783ETE+T exhibits −110pC typical charge injection at +3V supply. This parameter directly impacts accuracy in sample-and-hold circuits and switched-capacitor filters: uncancelled charge injection causes voltage glitches and settling errors. Its low value - combined with 0.1Ω RON flatness - makes the MAX4783ETE+T suitable for 16-bit+ precision data acquisition front-ends.
