Product details
Overview
The MAX4311ESD+T from Maxim Integrated is a 4-channel, unity-gain-stable video multiplexer-amplifier with rail-to-rail output, 345MHz -3dB bandwidth, 430V/µs slew rate, and 40ns channel switching time-designed for high-fidelity broadcast video signal routing in single-supply +4V to +10.5V systems.
For engineers reviewing the MAX4311ESD+T datasheet, MAX4311ESD+T pinout, MAX4311ESD+T application, or MAX4311ESD+T equivalent, key selection criteria include differential gain/phase error (0.06%/0.08°), low 10mVp-p switching transient, shutdown current (560µA), input common-mode range extending to VEE, and compatibility with 75Ω back-terminated video cables.
Technical Context
This device integrates a 4-input analog multiplexer with an adjustable-gain voltage-feedback amplifier optimized for closed-loop gains ≥+1V/V. Its architecture delivers rail-to-rail output swing (within 730mV of rails into 150Ω) while maintaining open-loop output impedance of only 8Ω across full output voltage range-minimizing load-induced gain error and bandwidth variation.
It supports single-supply operation (4V–10.5V) or dual supplies (±2V–±5.25V), features logic-compatible SHDN control, and achieves 0.05dB gain matching between channels over its -3dB bandwidth-enabling precise multichannel video switching without visible artifacts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 345MHz - supports full HD (1080p60) baseband video without attenuation in the luminance band |
| Slew Rate | 430V/µs - ensures distortion-free reproduction of fast video transitions (e.g., sync pulses, sharp edges) |
| Channel Switching Time | 40ns - enables glitch-free source switching during active video lines |
| Differential Gain/Phase Error | 0.06% / 0.08° - meets SMPTE RP-168 broadcast video fidelity requirements |

Pinout & Package
MAX4311ESD+T is housed in a 14-pin narrow SO package (SOIC-N14), with exposed pad for thermal enhancement and industry-standard footprint.
| Pin/Terminal | Circuit Role | Design Meaning |

| 5 | A0 | LSB address input for 4-channel selection (00–11 binary); TTL/CMOS compatible |
| 6 | A1 | MSB address input for 4-channel selection; enables deterministic channel routing under microcontroller control |
| 7 | SHDN | Active-low shutdown control; reduces supply current to 560µA and places output in high-Z state |
| 8, 9, 10, 11 | OUT | Single amplified output; rail-to-rail capable with 8Ω open-loop output impedance for stable gain into variable loads |
| 12 | VCC | Positive supply pin; accepts +4V to +10.5V single supply or +5.25V in dual-supply mode |
| 13 | VEE | Negative supply or ground reference; input common-mode extends to this rail |
| 14 | GND | Power ground connection; requires low-inductance path to minimize switching noise coupling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video multiplexer-amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4311EEE+ | 16-pin QSOP package; identical electrical specs but larger footprint and higher thermal resistance | Preferred for high-density PCBs where 14-pin SO layout is constrained; less suitable for automated optical inspection due to pitch | Select MAX4311ESD+T for space-constrained designs requiring narrow SO footprint and optimal thermal performance via exposed pad |
| THS4302DR | Single-channel, 1.8GHz bandwidth, no integrated multiplexer; requires external 4:1 analog switch | Used when ultra-wideband signal integrity (>1GHz) is prioritized over integration; adds board area and timing skew risk | Choose MAX4311ESD+T when system-level integration, low-glitch switching, and broadcast-grade video fidelity are required over raw bandwidth |
Compared with MAX4311EEE+, the MAX4311ESD+T offers superior thermal dissipation in a smaller 14-pin SO package; compared with THS4302DR, it provides monolithic 4-channel switching with guaranteed 40ns timing and 0.06% differential gain error-reducing BOM count and layout complexity for video routing applications.

FAQ
What is the maximum operating supply voltage for the MAX4311ESD+T?
The MAX4311ESD+T operates from a single supply of +4V to +10.5V or dual supplies of ±2V to ±5.25V. Absolute maximum supply voltage (VCC to VEE) is 12V. Exceeding +10.5V on VCC or applying more than ±5.25V in dual mode risks permanent damage and violates the specified operating conditions in the MAX4311ESD+T datasheet.
Does the MAX4311ESD+T support DC-coupled video inputs?
Yes, the MAX4311ESD+T supports DC-coupled video inputs because its input common-mode voltage range extends to the negative supply rail (VEE). This allows direct connection of baseband video signals without clamping diodes or AC-coupling capacitors-preserving low-frequency content critical for medical imaging and studio monitoring applications using the MAX4311ESD+T.
How does the MAX4311ESD+T achieve low switching transients?
The MAX4311ESD+T achieves 10mVp-p switching transients through matched internal switch timing, charge cancellation circuitry, and optimized amplifier settling behavior. Its 40ns channel switching time is tightly controlled, and the output amplifier's unity-gain stability ensures minimal overshoot-key to maintaining signal integrity during live video source changes using the MAX4311ESD+T.
Can the MAX4311ESD+T drive 75Ω coaxial cables directly?
Yes, the MAX4311ESD+T can drive 75Ω coaxial cables directly when used in back-terminated configurations. Its rail-to-rail output delivers sufficient voltage swing (within 730mV of rails into 150Ω) and low 8Ω open-loop output impedance ensures stable gain. For optimal performance with long cables, pair the MAX4311ESD+T with 75Ω series termination at the driver and 75Ω parallel termination at the load.
What is the function of the FB pin on the MAX4311ESD+T?
The MAX4311ESD+T does not have an FB (feedback) pin. Unlike the MAX4310/MAX4312 variants, the MAX4311ESD+T uses an internally compensated, unity-gain-stable amplifier architecture with no external feedback connections. Pin 7 is SHDN, pins 1–4 are IN0–IN3, and pins 8–11 are the output-confirming that FB is absent in this 14-pin SO variant per the MAX4311ESD+T pin configuration table.
