Product details
Overview
The MAX4314EEE+ from Maxim Integrated is a 4-channel, fixed-gain (+2V/V) high-speed video multiplexer-amplifier optimized for back-terminated 75Ω cable driving. It delivers 127MHz -3dB bandwidth, 430V/µs slew rate, 40ns channel switching time, and 0.09% differential gain error-enabling broadcast-grade video signal routing in SD/HD systems.
For engineers reviewing the MAX4314EEE+ datasheet, MAX4314EEE+ pinout, MAX4314EEE+ application, or MAX4314EEE+ equivalent, key selection criteria include its rail-to-rail output swing into 150Ω (±730mV from rails), input common-mode range extending to VEE, low 6.9mA quiescent current, and 16-pin QSOP package compatibility with video crosspoint switch matrices.
Technical Context
The MAX4314EEE+ integrates a 4:1 analog multiplexer with a voltage-feedback amplifier featuring internally trimmed 500Ω thin-film feedback resistors to fix gain at +2V/V. Its architecture supports single-supply operation from +4V to +10.5V (or ±2V to ±5.25V dual supply) and maintains open-loop output impedance of only 0.025Ω across the full output voltage range.
Channel selection uses three logic inputs (A0–A2) with TTL-compatible thresholds (VIL ≤ VEE + 1V, VIH ≥ VCC – 1V), while shutdown control (SHDN) reduces supply current to 560µA and places the output in high-impedance state. Input capacitance remains constant at 2pF regardless of channel state, ensuring predictable source loading.

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+ | 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 thermal pad | Select for legacy SO-based designs where board space permits larger body size and lower thermal performance |
| MAX4311EEE+ | 4-channel like MAX4314EEE+, but adjustable-gain (+1V/V min); 345MHz bandwidth, higher power (6.9mA vs 6.9mA same, but higher slew-induced dissipation) | Used where variable gain or wider bandwidth is needed; less optimized for fixed 75Ω cable driving | Select when system requires programmable gain or >127MHz signal path - not drop-in replacement |
Compared with MAX4314ESD+ and MAX4311EEE+, the MAX4314EEE+ offers superior thermal performance via QSOP exposed pad, guaranteed +2V/V gain stability for cable driving, and identical quiescent current - making it the preferred choice for space-constrained, thermally demanding broadcast video routing.

FAQ
What is the operating supply voltage range for the MAX4314EEE+?
The MAX4314EEE+ operates from a single +4V to +10.5V supply or dual supplies of ±2V to ±5.25V. This wide range supports both low-voltage portable video systems and standard 5V/±5V industrial video equipment. The device maintains specified AC performance across this entire range, including 127MHz bandwidth and 430V/µs slew rate at minimum +4V supply.
Does the MAX4314EEE+ support rail-to-rail input common-mode voltage?
Yes, the MAX4314EEE+ input common-mode voltage range extends to the negative supply rail (VEE), enabling true ground-sensing operation in single-supply configurations. At VCC = +5V, the input range is 0V to +2.3V. This allows direct interfacing with baseband video signals referenced to ground without level-shifting circuitry - critical for preserving DC-coupled video integrity.
How does the MAX4314EEE+ achieve low switching transients during channel selection?
The MAX4314EEE+ achieves ultra-low 10mVp-p switching transients through matched internal transistor pairs in its 4:1 multiplexer and charge-balanced switching architecture. Combined with 40ns channel switching time and internal +2V/V gain stabilization, this minimizes visible glitches during real-time video source changes - a requirement verified in broadcast-grade test conditions per EIA-708 and SMPTE standards.
Can the MAX4314EEE+ drive 75Ω coaxial cables directly?
Yes, the MAX4314EEE+ is explicitly optimized for driving back-terminated 75Ω coaxial cables. Its fixed +2V/V gain, rail-to-rail output swing into 150Ω (equivalent to two 75Ω loads in parallel), and low 0.025Ω open-loop output impedance ensure minimal gain error and flat frequency response up to 127MHz - meeting the requirements for SD and HD video transmission without external gain-setting components.
What is the function of the SHDN pin on the MAX4314EEE+?
The SHDN pin on the MAX4314EEE+ is an active-low shutdown control that reduces quiescent supply current from 6.9mA to 560µA and places the output in a high-impedance state (typically 35kΩ). This enables power gating in multi-channel video systems and allows paralleling of multiple MAX4314EEE+ outputs to construct larger switch matrices - with only the active device driving the shared bus.
