Product details
Overview
MAX4754AEBE+ 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 matching, 0.2Ω on-resistance flatness, and 0.035% THD at 20Hz–20kHz into 32Ω, enabling high-fidelity headset/speaker switching in cellular phones and notebook computers.
For engineers reviewing the MAX4754AEBE+ datasheet, MAX4754AEBE+ pinout, MAX4754AEBE+ application, or MAX4754AEBE+ equivalent, key selection criteria include rail-to-rail signal handling (0V to V+), dual logic control inputs (INA/INB), ultra-low leakage (±10nA off-leakage), and UCSP-16 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4754AEBE+ implements four independent SPDT switches using CMOS process technology, each with matched NO/NC paths and bidirectional signal capability. Its control architecture uses two non-rail-to-rail logic inputs (INA, INB) that accept +1.8V to +5.5V supplies while maintaining low quiescent current (6.5µA typical at V+ = 5.5V).
Signal integrity is preserved via 10MHz –3dB bandwidth, –65dB off-isolation, –90dB crosstalk, and <2ns break-before-make timing - all specified across –40°C to +85°C. The device supports true rail-to-rail analog operation and exhibits minimal on-resistance variation (<0.55Ω max ΔRON) over temperature and voltage.
Key Specifications

| Channel Matching (ΔRON) | 0.1Ω typ (maintains balanced stereo signal integrity) |
| THD + Noise | 0.035% typ at 20Hz–20kHz (meets high-fidelity earpiece/headphone requirements) |
| Supply Range | +1.8V to +5.5V (supports Li-ion battery, 3.3V, and 5V system rails) |
| Off-Leakage Current | ±10nA max (prevents DC offset and battery drain in standby) |
| Break-Before-Make Time | 2ns typ (eliminates audible click/pop during speaker/headset switching) |
| Operating Temperature | –40°C to +85°C (qualified for industrial and mobile end-equipment) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4754EBE+ | Non-A version: higher supply current (2µA vs. 6.5µA), no improved logic threshold specs | Limited to lower-power systems where ultra-low standby current is not required | Select MAX4754EBE+ only if cost sensitivity outweighs battery-life optimization needs |
| MAX4756AEBE+ | Quad SPDT with single control (INA) + enable (EN); lacks second control input (INB) | Better suited for simple ON/OFF audio path selection rather than dual-path routing | Choose MAX4756AEBE+ when routing logic is centralized and INB functionality is unnecessary |
Compared with MAX4754EBE+, the MAX4754AEBE+ delivers 3× lower supply current and tighter logic thresholds for mixed-voltage systems; versus MAX4756AEBE+, it provides independent dual-switch control essential for complex speaker/headset arbitration.

FAQ
What is the maximum analog signal voltage range supported by the MAX4754AEBE+?
The MAX4754AEBE+ supports rail-to-rail analog signals from 0V to V+, where V+ ranges from +1.8V to +5.5V. This allows full-swing audio signals (e.g., ±1.5V centered at V+/2) without clipping or distortion, making it ideal for 3V and 5V portable systems. The specification is guaranteed across –40°C to +85°C.
How does the MAX4754AEBE+ differ from the standard MAX4754EBE+?
The MAX4754AEBE+ features improved power-supply current (6.5µA typical vs. 2µA for MAX4754EBE+) and enhanced logic input thresholds optimized for non-rail-to-rail control signals. These refinements reduce system power consumption and improve noise immunity in mixed-voltage digital interfaces, directly benefiting battery-operated devices.
Can the MAX4754AEBE+ be used to drive an 8Ω speaker directly?
No - the MAX4754AEBE+ is a signal-routing switch, not a power amplifier. It can route audio signals to an 8Ω speaker path but requires an external amplifier stage. Its 300mA continuous current rating supports driving amplifier inputs or low-power transducers, but not direct 8Ω speaker loads at full volume.
What is the purpose of the exposed paddle (EP) on the MAX4754AEBE+ UCSP package?
The exposed paddle (EP) on the MAX4754AEBE+ must be soldered to a GND plane. It serves dual functions: improving thermal dissipation (derating 8.2mW/°C above +70°C) and reducing ground inductance to minimize switching noise coupling into sensitive analog paths - critical for THD and crosstalk performance.
Is the MAX4754AEBE+ pin-compatible with the MAX4755EBE+?
No - the MAX4754AEBE+ and MAX4755EBE+ share the same UCSP-16 package and pinout, but their internal switch configurations differ: MAX4754AEBE+ has four standard SPDTs, while MAX4755EBE+ adds 11.5Ω resistors in series with NC1/NC2 for 8Ω-to-32Ω speaker impedance transformation. Functionally, they are not drop-in replacements.
