Product details
Overview
MAX4754AEBE+T from Maxim Integrated is a quad single-pole double-throw (SPDT) analog switch IC designed for low-distortion audio-signal routing in portable electronics. It features 0.5Ω typical on-resistance, 0.1Ω channel-to-channel on-resistance matching, and rail-to-rail signal handling from +1.8V to +5.5V supply, enabling high-fidelity headset/speaker switching in cellular phones and notebook computers.
For engineers reviewing the MAX4754AEBE+T datasheet, MAX4754AEBE+T pinout, MAX4754AEBE+T application, or MAX4754AEBE+T equivalent, key selection criteria include its ultra-low RON flatness (0.2Ω typ), 0.035% THD at 20Hz–20kHz, break-before-make timing (2ns), and UCSP-16 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4754AEBE+T implements four independent SPDT switches controlled by two logic inputs (INA, INB), each driving two switches with complementary states. Its CMOS process delivers rail-to-rail analog signal support and logic-level tolerance up to +5.5V regardless of V+, enabling mixed-voltage system interfacing.
Unlike the MAX4755 (which adds 11.5Ω series resistors on NC paths) or MAX4756A (single control + EN), the MAX4754AEBE+T uses dual independent control lines without enable functionality-optimized for discrete audio path selection rather than global shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 0.5Ω typical at V+ = 2.7V, 10mA - ensures minimal insertion loss and voltage drop in audio paths. |
| On-resistance matching | 0.1Ω typical - maintains balanced signal integrity across stereo or multi-channel audio routing. |
| Total harmonic distortion | 0.035% typical at 1VP-P, 20Hz–20kHz - preserves audio fidelity in headset and speaker outputs. |
| Supply voltage range | +1.8V to +5.5V - supports direct integration with Li-ion battery rails and 3.3V/5V system logic. |
| Break-before-make time | 2ns guaranteed - prevents momentary short-circuits during audio path reconfiguration. |
| Off-isolation | -65dB at 100kHz - suppresses crosstalk between active and inactive audio channels. |
| Logic input voltage range | 0.5V to +5.5V regardless of V+ - enables robust interfacing with diverse microcontroller I/O levels. |
Pinout & Package
MAX4754AEBE+T is housed in a 16-bump, 2mm × 2mm chip-scale package (UCSP™) with exposed paddle (EP) connected to GND for thermal and electrical stability. The package footprint minimizes board area while maintaining signal integrity for high-frequency audio signals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| NO1–NO4 | Normally open analog terminals | Four independent output paths activated when corresponding switch closes to COMx. |
| NC1–NC4 | Normally closed analog terminals | Four alternate output paths active when switch is unasserted; no series resistor (unlike MAX4755). |
| COM1–COM4 | Common analog terminals | Input nodes shared across NO/NC pairs; bidirectional signal routing capability. |
| INA, INB | Digital control inputs | INA controls NO1/NC1/NO2/NC2; INB controls NO3/NC3/NO4/NC4 - dual independent switching. |
| V+ | Positive supply | +1.8V to +5.5V analog/digital supply; bypassing with 0.1µF to GND required for noise immunity. |
| GND | Ground reference | Return path for analog signals and digital logic; EP must be soldered to GND plane. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low on-resistance | 0.5Ω typical enables <0.1dB insertion loss in 32Ω headphone loads, preserving loudness and SNR. |
| Channel-to-channel RON matching | 0.1Ω typical ensures amplitude balance in stereo audio paths, critical for L/R channel consistency. |
| Rail-to-rail signal handling | Supports full 0V to V+ analog swing - eliminates clipping in 3.3V or 5V audio systems without level-shifting. |
| Low THD + noise | 0.035% THD at 20Hz–20kHz meets high-fidelity requirements for earpiece and headset applications. |
| Mixed-voltage logic interface | IN_ accepts up to +5.5V regardless of V+ - simplifies connection to 5V microcontrollers in 3.3V systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4754ETE+T | Same electrical specs but in 16-pin TQFN-EP (4mm × 4mm); higher thermal dissipation (1349mW vs. 660mW). | Preferred for thermally demanding environments or where reflow compatibility with larger QFN footprints exists. | Select MAX4754ETE+T when board layout accommodates 4mm × 4mm and thermal management requires higher PD. |
| MAX4754AETE+T | Identical functionality and specs to MAX4754AEBE+T, differing only in TQFN-EP packaging (same pinout, same UCSP die). | No functional difference; used where TQFN assembly infrastructure is standardized and UCSP rework is avoided. | Choose MAX4754AETE+T for production lines optimized for QFN placement and inspection, not size-constrained designs. |
Compared with MAX4754AEBE+T, the MAX4754ETE+T offers better thermal performance in high-power audio routing, while MAX4754AETE+T provides identical functionality in a more manufacturable package-neither is pin-compatible with MAX4755 or MAX4756A due to differing control architectures and NC-path resistors.

FAQ
What is the maximum analog signal voltage range supported by the MAX4754AEBE+T?
The MAX4754AEBE+T supports rail-to-rail analog signals from 0V to V+, where V+ ranges from +1.8V to +5.5V. This means the device passes full-swing audio signals without clipping-for example, a 0V to 3.3V signal with V+ = 3.3V or 0V to 5.0V with V+ = 5.0V. Internal ESD clamps limit absolute max to (V+ + 0.3V) on analog pins, so operation within V+ ensures safe, linear conduction.
Does the MAX4754AEBE+T include an enable pin like the MAX4756A?
No, the MAX4754AEBE+T does not have an enable (EN) pin. It uses two dedicated logic inputs-INA and INB-to independently control two pairs of SPDT switches (switches 1–2 and 3–4). In contrast, the MAX4756A uses INA for selection and EN for global on/off control. This makes MAX4754AEBE+T ideal for discrete path selection, while MAX4756A suits applications needing simultaneous disable of all switches.
Can the MAX4754AEBE+T be used to drive an 8Ω speaker directly?
No-the MAX4754AEBE+T is not rated for direct 8Ω speaker drive. Its continuous current rating per terminal is ±300mA, but sustained 8Ω loading at typical audio voltages exceeds safe power dissipation limits. It is intended for signal routing *to* amplifier inputs or headset jacks-not as a power output stage. For 8Ω speaker switching, use the MAX4755 (which includes 11.5Ω NC-path resistors) or add external amplification.
What is the thermal performance difference between the UCSP and TQFN packages of the MAX4754A?
The MAX4754AEBE+T (UCSP-16) has a continuous power dissipation of 660mW at +70°C, derating at 8.2mW/°C above that temperature. The TQFN version (MAX4754AETE+T) supports 1349mW at +70°C, derating at 16.9mW/°C. The larger thermal mass and exposed paddle of the TQFN allow ~2× higher power handling-critical in high-duty-cycle audio switching or ambient temperatures exceeding 85°C.
Is the MAX4754AEBE+T compatible with 1.8V logic control inputs?
Yes-the MAX4754AEBE+T accepts logic inputs down to 0.5V (VIL) and up to +5.5V regardless of V+, making it fully compatible with 1.8V GPIOs. When V+ = 1.8V, the input thresholds remain valid: VIL ≤ 0.5V and VIH ≥ 1.4V. This allows direct interfacing with low-voltage microcontrollers without level shifters, reducing BOM count and layout complexity.
