Product details
Overview
MAX4780ETE from Maxim Integrated is a low-voltage, quad 2:1 analog multiplexer IC with 0.7Ω on-resistance at +2.7V supply, 20ns turn-on time, and rail-to-rail signal handling from GND to V+. It operates from a single +1.6V to +4.2V supply and consumes less than 1µW quiescent power, making it suitable for battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4780ETE datasheet, MAX4780ETE pinout, MAX4780ETE application, or MAX4780ETE equivalent, this device supports precise analog signal selection in space-constrained portable electronics where low RON, fast switching, and +1.8V CMOS logic compatibility are critical design requirements.
Technical Context
The MAX4780ETE implements four independent 2:1 analog switches using CMOS process technology, each with a normally open (NO) and normally closed (NC) path controlled by a single address input A0. Its enable (EN) pin provides global shutdown capability, placing all COM outputs in high-impedance state when driven high.
Switching behavior is break-before-make, with guaranteed tBBM ≤ 1ns at +2.7V supply. Analog signal range spans full rail-to-rail (GND to V+), and bidirectional operation allows NO/NC/COM pins to serve as inputs or outputs depending on system topology.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.6V to +4.2V - enables direct integration into Li-ion, Li-poly, and single-cell alkaline/battery systems without level-shifting. |
| On-Resistance (RON) | 0.7Ω at +2.7V - minimizes voltage drop and power loss in high-current analog paths (e.g., speaker routing, sensor front-ends). |
| RON Flatness | 0.1Ω at +2.7V - ensures consistent gain and linearity across full analog signal swing (0V to V+). |
| Turn-On / Turn-Off Time | tON = 20ns, tOFF = 8ns - supports high-speed signal routing in audio codecs and burst-mode data acquisition. |
| Logic Compatibility | +1.8V CMOS - allows direct interface with low-voltage microcontrollers and baseband processors without external translators. |
| Off-Leakage Current | ±5nA max at +85°C - preserves signal integrity in high-impedance sensor and precision measurement circuits. |
| Bandwidth | 123MHz - supports wideband analog signals including audio, video, and IF frequencies up to ~100MHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4784ETE | Includes second address input A1 for independent 2-bit control of all four channels; lacks EN pin. | Preferred for systems requiring per-channel path selection (e.g., differential sensor pairs, independent audio sources). | Select MAX4784ETE when discrete control of each 2:1 switch is required; MAX4780ETE is optimal for synchronized quad selection with global enable. |
| TMUX1574RTER | 4-channel 2:1 mux with 0.5Ω RON at 3.3V, but requires minimum 1.08V logic supply and has higher 5.5µA I+. | Better suited for 3.3V-only systems with tighter RON tolerance; less ideal for sub-2V battery operation. | Choose TMUX1574RTER only if operating strictly at ≥3.0V with priority on lowest possible RON; MAX4780ETE offers broader voltage range and lower power. |
Compared with MAX4784ETE and TMUX1574RTER, the MAX4780ETE uniquely combines global enable (EN), single-address simplicity, ultra-low power (<2µA), and full 1.6V–4.2V operation-making it the optimal choice for cost-sensitive, battery-constrained designs requiring synchronized quad analog routing.

FAQ
What is the maximum continuous current rating for each switch in the MAX4780ETE?
The MAX4780ETE supports ±300mA continuous current through each COM, NO, and NC terminal. This rating applies across the full operating temperature range (–40°C to +85°C) and ensures reliable operation in speaker drivers, sensor interfaces, and power-path applications without thermal derating under typical PCB layout conditions.
Does the MAX4780ETE support rail-to-rail analog signal switching?
Yes, the MAX4780ETE supports rail-to-rail analog signal switching from GND to V+, with minimal variation in on-resistance across the full voltage range. At +2.7V supply, RON flatness is specified at 0.1Ω, ensuring consistent performance for audio, sensor, and communication signals spanning the entire supply rail.
Can the MAX4780ETE be used with a +1.8V supply voltage?
Yes, the MAX4780ETE operates down to +1.6V and is fully functional at +1.8V. At this supply, typical on-resistance is 2Ω (max 5Ω), logic thresholds are VIH = +1.0V and VIL = +0.4V, and switching times are tON = 25ns, tOFF = 10ns - making it suitable for ultra-low-voltage battery systems.
What is the function of the EN pin on the MAX4780ETE?
The EN (Enable) pin on the MAX4780ETE provides global shutdown control: driving EN high places all COM outputs in high-impedance state, disconnecting all analog paths regardless of A0 state. Driving EN low enables normal switching operation. This feature is essential for power gating and fault isolation in portable electronics.
Is the exposed pad (EP) on the MAX4780ETE electrically connected?
Yes, the exposed pad (EP) on the MAX4780ETE is internally connected to GND and must be soldered to a large PCB ground plane for optimal thermal performance. It is not intended as an electrical signal connection point, but proper thermal coupling reduces junction temperature rise and improves long-term reliability under sustained load conditions.
