Product details
Overview
The MAX4314ESD+T from Maxim Integrated is a 4-channel, fixed-gain (+2V/V) video multiplexer-amplifier optimized for driving back-terminated 75Ω coaxial cables in broadcast and professional video systems. It delivers 127MHz -3dB bandwidth, 430V/µs slew rate, 40ns channel switching time, and ultra-low 10mVp-p switching transients while operating from a single +4V to +10.5V supply.
For engineers reviewing the MAX4314ESD+T datasheet, MAX4314ESD+T pinout, MAX4314ESD+T application, or MAX4314ESD+T equivalent, key selection criteria include fixed +2V/V gain stability under 75Ω loads, rail-to-rail output swing (within 730mV of rails into 150Ω), differential gain/phase error of 0.09%/0.03°, and low-power shutdown mode reducing ICC to 560µA.
Technical Context
The MAX4314ESD+T integrates a 4-channel analog multiplexer with an internal +2V/V fixed-gain voltage-feedback amplifier using thin-film 500Ω feedback resistors. Its architecture enables stable operation into 75Ω back-terminated video lines without external gain-setting components.
It features rail-to-rail outputs with open-loop output impedance of only 8Ω across the full voltage range, enabling consistent gain accuracy under varying load conditions. Input common-mode range extends to the negative rail, supporting ground-sensing video sources while maintaining 73–95dB CMRR over 0–2.2V.

Pinout & Package
MAX4314ESD+T is housed in a 14-pin narrow SO package (SOIC-N14) with exposed pad for thermal performance. Pin assignments are validated per Maxim's official datasheet Rev 3 (19-1379).
| Pin/Terminal | Circuit Role | Design Meaning |

| SHDN | Active-low shutdown control | Drives output to high-impedance state and reduces ICC to 560µA when pulled low |
| VCC, VEE | Power supply pins | Support single-supply operation from +4V to +10.5V (VEE = GND) or dual ±2V to ±5.25V |
| IN0–IN3 | Analog multiplexer inputs | Four independent video input channels; input capacitance constant at 2pF regardless of on/off state |
| OUT | Amplified output | Rail-to-rail output capable of driving 150Ω to within 730mV of rails; open-loop ZOUT = 8Ω |
| GND | Ground reference | Common return path for signal and power; requires low-impedance PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar video multiplexer-amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4314EEE+ | Same electrical specs but in 16-pin QSOP package; larger footprint, better thermal dissipation | Preferred for high-density boards where SOIC-N14 thermal limits are exceeded | Select MAX4314EEE+ when board layout allows larger package and higher ambient temperature operation is required |
| THS4302DR | Single-channel, 1.8GHz bandwidth, no integrated mux; requires external 4:1 analog switch | Used where higher bandwidth (>1GHz) is needed but channel count flexibility is less critical | Choose THS4302DR only when system design separates multiplexing and amplification functions and demands >1GHz small-signal response |
Compared with MAX4314EEE+ and THS4302DR, the MAX4314ESD+T uniquely combines 4-channel selection, fixed +2V/V gain, and 127MHz bandwidth in a compact 14-pin narrow SO package-enabling minimal BOM count and simplified layout for cost-sensitive broadcast and medical video routing.

FAQ
What is the maximum supply voltage for the MAX4314ESD+T?
The MAX4314ESD+T supports a maximum supply voltage of 12V across VCC to VEE. Its recommended operating supply range is +4V to +10.5V for single-supply use (VEE = GND) or ±2V to ±5.25V for dual-supply configurations. Exceeding 12V absolute maximum rating risks permanent device damage, as specified in the Absolute Maximum Ratings table of the MAX4314ESD+T datasheet.
Does the MAX4314ESD+T require external gain-setting resistors?
No, the MAX4314ESD+T does not require external gain-setting resistors. It incorporates internal thin-film 500Ω feedback resistors that fix the closed-loop gain at +2V/V (6dB). This eliminates component count, layout sensitivity, and resistor matching concerns-unlike the adjustable-gain MAX4311 variant-and ensures stable performance into 75Ω back-terminated video cables.
Can the MAX4314ESD+T drive 75Ω coaxial cable directly?
Yes, the MAX4314ESD+T is explicitly optimized for driving back-terminated 75Ω coaxial cables. Its fixed +2V/V gain, 127MHz bandwidth, and rail-to-rail output stage deliver full-swing video signals while maintaining 0.09% differential gain and 0.03° differential phase error-key requirements for broadcast-quality video transmission as confirmed in the MAX4314ESD+T datasheet Applications Information section.
What is the input capacitance of the MAX4314ESD+T multiplexer channels?
The MAX4314ESD+T exhibits a constant 2pF input capacitance on each IN0–IN3 channel, whether the channel is selected (on) or unselected (off). This stable capacitance ensures predictable source loading and avoids signal reflection or frequency-dependent crosstalk-critical for maintaining flat frequency response in multi-source video routing applications.
How does the shutdown function affect the output impedance of the MAX4314ESD+T?
When the SHDN pin is driven low, the MAX4314ESD+T places its OUT terminal in a high-impedance state with a typical disabled output resistance of 1Ω. This allows safe paralleling of multiple MAX4314ESD+T devices on a shared bus, enabling scalable video matrix architectures where only one device is active at a time-verified in the MAX4314ESD+T DC Electrical Characteristics table under "Disabled Output Resistance".
