Product details
Overview
MAX4314EEE+T from Maxim Integrated is a 4-channel, fixed-gain (+2V/V) video multiplexer-amplifier with rail-to-rail output, 127MHz −3dB bandwidth, 430V/µs slew rate, and 40ns channel switching time. It operates from a single +4V to +10.5V supply and delivers broadcast-grade video performance with 0.09% differential gain error and 0.03° differential phase error, ideal for 75Ω video cable driving in professional video routing systems.
For engineers reviewing the MAX4314EEE+T datasheet, MAX4314EEE+T pinout, MAX4314EEE+T application, or MAX4314EEE+T equivalent, key selection criteria include fixed +2V/V gain stability under 150Ω back-termination, ultra-low 10mVp-p switching transient, shutdown current of 560µA, and QSOP-16 package compatibility with high-density video switch matrix layouts.
Technical Context
The MAX4314EEE+T integrates a 4-input analog multiplexer with a voltage-feedback amplifier featuring internally trimmed 500Ω thin-film feedback resistors that set a precise +2V/V gain. Its architecture supports single-supply operation down to +4V while maintaining input common-mode range extending to the negative rail and rail-to-rail output swing within 730mV of VCC into 150Ω.
Channel selection is controlled via three logic inputs (A0–A2), enabling full 4-channel addressing. The device achieves low crosstalk (−60dB at 10MHz) and high off-isolation (−82dB), with an open-loop output impedance of 0.025Ω ensuring minimal gain error across varying loads typical in video distribution systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar video multiplexer-amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4314ESD+T | Same electrical specs; packaged in 14-pin narrow SO instead of 16-pin QSOP | Requires PCB layout change due to different footprint and pinout; no pin compatibility | Select for legacy SO-based designs where board space permits larger package |

FAQ
What is the operating supply voltage range for the MAX4314EEE+T?
The MAX4314EEE+T operates from a single +4V to +10.5V supply or dual supplies of ±2V to ±5.25V. This wide range supports both portable battery-powered video gear and standard 5V/±5V industrial systems. The device maintains specified performance-including 127MHz bandwidth and 0.09% differential gain error-across the full voltage range, with quiescent current scaling linearly from 6.9mA at +5V to 7.8mA at +10.5V.
Does the MAX4314EEE+T require external gain-setting resistors?
No, the MAX4314EEE+T does not require external gain-setting resistors. It features an internally trimmed +2V/V fixed-gain amplifier using matched 500Ω thin-film resistors. This eliminates component count, layout sensitivity, and gain drift associated with external networks-ensuring consistent 0.09% differential gain error and stable performance across temperature and production lots. External resistors are only needed for the MAX4310–MAX4312 variants.
What is the maximum capacitive load the MAX4314EEE+T can drive stably?
The MAX4314EEE+T can drive up to 47pF capacitive load without isolation resistance while maintaining stability and flat frequency response. For heavier loads (e.g., >47pF), a series isolation resistor (e.g., 27Ω) between OUT and the load restores phase margin and suppresses ringing-as verified in Figure 9 of the datasheet. This design flexibility supports direct connection to PCB traces, connectors, and moderate-length cables without compromising video signal integrity.
How does the shutdown function affect the output state of the MAX4314EEE+T?
When SHDN is driven low, the MAX4314EEE+T enters low-power shutdown mode: quiescent supply current drops to 560µA, and the output is placed in a high-impedance state with typical resistance of 35kΩ. This allows multiple MAX4314EEE+T outputs to be wired-OR'd on a shared bus-only the active device drives the line, eliminating contention and enabling scalable video matrix architectures without external analog switches.
Is the MAX4314EEE+T pin-compatible with other devices in the MAX4310–MAX4315 family?
No, the MAX4314EEE+T is not pin-compatible with other members of the MAX4310–MAX4315 family. While it shares the same 16-pin QSOP footprint with MAX4311EEE+T and MAX4312EEE+T, its pin mapping differs significantly: MAX4314EEE+T uses pins 3, 6, 8, 9, and 11 for OUT (multiplexed), whereas MAX4311EEE+T uses pins 3, 6, and 9 only-and MAX4312EEE+T uses pins 3, 6, 8, 9, 11, and 12. Always consult the Pin Description table (page 11) before substituting.
