Product details
Overview
MAX4314ESD-T from Maxim Integrated is a 4-channel video multiplexer-amplifier with fixed +2V/V gain, 127MHz -3dB bandwidth, 40ns channel switching time, and rail-to-rail output driving capability into 150Ω loads - designed for broadcast video crosspoint switching and back-terminated cable driving.
For engineers reviewing the MAX4314ESD-T datasheet, MAX4314ESD-T pinout, MAX4314ESD-T application, or MAX4314ESD-T equivalent, key selection criteria include differential gain/phase error (0.09%/0.03°), shutdown current (560µA), input common-mode range extending to VEE, and compatibility with single +4V to +10.5V supplies.
Technical Context
The MAX4314ESD-T integrates a 4:1 analog multiplexer with a fixed-gain +2V/V voltage-feedback amplifier optimized for driving 75Ω coaxial cables with back-termination. Its internal thin-film feedback resistors (500Ω each) set gain and contribute to low output impedance (0.025Ω open-loop).
It features 40ns channel switching with only 10mVp-p transient, rail-to-rail output swing (within 730mV of rails into 150Ω), and input common-mode range from VEE to VCC − 2.7V - enabling ground-sensing operation in single-supply video systems.

Pinout & Package
MAX4314ESD-T is housed in a 14-pin narrow SO package (SOIC-N14), with 1.27mm pitch, 8.65mm × 3.9mm body, and exposed pad not present. Pin functions are validated per Maxim's official datasheet revision 3 (19-1379).
| Pin/Terminal | Circuit Role | Design Meaning |

| OUT | Amplified output | Rail-to-rail output capable of ±95mA drive into 30Ω, swings to within 730mV of rails into 150Ω |
| GND | Ground reference | Return path for VEE and logic; requires low-impedance PCB ground plane per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Fixed +2V/V gain architecture | Internally trimmed 500Ω thin-film resistors eliminate external gain-setting components and ensure ±0.1dB gain matching across channels |
| Rail-to-rail output stage | Drives 150Ω loads to within 730mV of VCC and 30mV above VEE - critical for 75Ω video line driving with back-termination |
| Ultra-low switching transient | 10mVp-p glitch during channel change prevents visible artifacts in real-time video switching |
| Input common-mode to negative rail | Enables DC-coupled ground-referenced video signal routing without level-shifting circuitry |
| Low-power shutdown mode | Reduces ICC to 560µA and isolates output - allows parallel connection of multiple MAX4314ESD-T devices in large switch matrices |

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 core functionality but in 16-pin QSOP package (5.3mm × 10mm vs. SOIC-N14's 8.65mm × 3.9mm); identical electrical specs | Preferred for higher-density PCB layouts where thermal dissipation or board space permits larger footprint | Select MAX4314EEE+ when QSOP mounting infrastructure exists and board area allows larger package |
| THS4302DR | Single-channel, 1.8GHz bandwidth, no integrated mux; requires external 4:1 analog switch and gain stage | Suitable for ultra-wideband (>500MHz) applications where MAX4314ESD-T's 127MHz is insufficient | Choose THS4302DR only when bandwidth >200MHz is mandatory and discrete mux integration is acceptable |
Compared with MAX4314EEE+ and THS4302DR, the MAX4314ESD-T uniquely combines 4-channel multiplexing, fixed +2V/V gain, and broadcast-grade video performance in a compact narrow-SO package - offering optimal integration, layout simplicity, and cost efficiency for standard-definition to full-HD video routing.

FAQ
What supply voltage range does the MAX4314ESD-T support?
The MAX4314ESD-T operates from a single +4V to +10.5V supply (with VEE = GND) or dual supplies of ±2V to ±5.25V. This wide range enables flexibility in both portable and mains-powered video equipment. The device maintains specified performance - including 127MHz bandwidth and 0.09% differential gain error - across the entire operating voltage window. Internal biasing remains stable, and rail-to-rail output swing is preserved down to +4V.
Does the MAX4314ESD-T require external gain-setting resistors?
No, the MAX4314ESD-T does not require external gain-setting resistors. It incorporates internally trimmed 500Ω thin-film feedback resistors that fix the closed-loop gain at +2V/V (6dB). This eliminates component count, layout sensitivity, and resistor tolerance drift - ensuring consistent gain matching (±0.05dB) and flat frequency response. External resistors are neither needed nor recommended for basic operation.
How does the MAX4314ESD-T handle video cable driving with back-termination?
The MAX4314ESD-T is optimized for driving 75Ω coaxial cables with back-termination via its fixed +2V/V gain, low 0.025Ω open-loop output impedance, and rail-to-rail output stage. When paired with a 75Ω load to ground, it delivers full-swing output (within 730mV of rails) while maintaining <0.1dB gain flatness to 100MHz. Its 127MHz bandwidth and −76dBc THD ensure minimal distortion over typical broadcast cable lengths.
What is the function of the SHDN pin on the MAX4314ESD-T?
The SHDN pin on the MAX4314ESD-T is an active-low digital control that places the device in low-power shutdown mode when pulled ≤ VIL (VEE + 1V). In shutdown, quiescent current drops to 560µA and the output enters a high-impedance state (~35kΩ). This enables power gating in multi-device switch matrices and eliminates signal contention when paralleling outputs - a key feature for scalable video routing architectures.
Can the MAX4314ESD-T be used with ground-referenced video inputs?
Yes, the MAX4314ESD-T supports ground-referenced video inputs because its input common-mode voltage range extends to the negative supply rail (VEE), which is typically GND in single-supply configurations. This allows direct coupling of 0V-referenced CVBS, YPbPr, or RGB signals without level-shifting circuitry. Performance metrics - including 0.09% differential gain error and 40ns switching - are fully specified under this condition.
