Product details
Overview
The MAX4314ESD+ from Maxim Integrated is a 4-channel, fixed-gain (+2V/V) video multiplexer-amplifier optimized for back-terminated 75Ω cable driving in broadcast and multimedia 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+ datasheet, MAX4314ESD+ pinout, MAX4314ESD+ application, or MAX4314ESD+ equivalent, key selection criteria include its rail-to-rail output swing (within 730mV of rails into 150Ω), differential gain/phase error of 0.09%/0.03°, shutdown current of 560µA, and compatibility with 14-pin narrow SO package layouts.
Technical Context
The MAX4314ESD+ integrates a 4-input analog multiplexer with a voltage-feedback amplifier featuring internally trimmed 500Ω thin-film feedback resistors to fix gain at +2V/V. Its architecture enables stable operation into 75Ω back-terminated coaxial cables without external gain-setting components.
Channel selection is controlled via three logic inputs (A0–A2), supporting full 4-channel addressing. The SHDN pin places outputs in high-impedance state and reduces supply current to 560µA, enabling power-aware matrix switching in multi-device configurations.

Pinout & Package
MAX4314ESD+ is housed in a 14-pin narrow SO package (SOIC-N14), with exposed pad not present and no thermal slug. Pin pitch is 1.27mm; body width is 3.9mm.
| Pin | Circuit Role | Design Meaning |
|---|---|---|

| 2 | A1 | MSB channel address input - completes 2-bit binary encoding for 4-channel selection |
| 3 | SHDN | Active-low shutdown control - pulls output to high-Z and cuts supply current to 560µA |

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 (5.3mm width vs. 3.9mm SO); different pinout and footprint | Preferred for space-constrained PCBs where QSOP layout is already standardized | Select MAX4314ESD+ for narrow SO footprint compatibility; choose MAX4314EEE+ only if QSOP is required for board reuse |
| THS7314DR | 4-channel, +2V/V gain, 150MHz bandwidth, but requires external gain resistors and has higher 1.2mA quiescent current | Used in cost-sensitive consumer AV receivers where external resistor tolerance is acceptable | MAX4314ESD+ offers superior integration and lower power; THS7314DR may be chosen only if TI supply chain preference applies |
Compared with MAX4314EEE+ and THS7314DR, the MAX4314ESD+ provides the narrowest SO footprint, lowest shutdown current (560µA), and fully integrated fixed-gain architecture-making it optimal for compact, low-power broadcast and professional video equipment.

FAQ
What is the operating supply voltage range for the MAX4314ESD+?
The MAX4314ESD+ operates from a single +4V to +10.5V supply or dual ±2V to ±5.25V supplies. In single-supply mode, VEE is connected to ground. This wide range supports both 5V and 9V systems without level-shifting, and the rail-to-rail output stage maintains full swing across the entire voltage window. The MAX4314ESD+ remains functional down to 4.0V, making it suitable for brownout-tolerant video equipment.
Does the MAX4314ESD+ require external gain-setting resistors?
No, the MAX4314ESD+ 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 due to external resistor tolerance or temperature coefficient-ensuring consistent 2.0V/V gain (±0.05dB) across process, voltage, and temperature for the MAX4314ESD+.
What is the maximum capacitive load the MAX4314ESD+ can drive stably?
The MAX4314ESD+ can drive up to 47pF directly with minimal peaking, as verified in typical operating characteristics. For heavier capacitive loads (e.g., >60pF), an external 27Ω series isolation resistor is recommended at the output to maintain phase margin and prevent oscillation. This design guidance is explicitly validated in Figure 9 of the MAX4314ESD+ datasheet and applies to PCB trace capacitance and connector parasitics in real-world video routing layouts.
How does the MAX4314ESD+ handle input common-mode voltage near the negative rail?
Unlike many amplifiers, the MAX4314ESD+ supports input common-mode voltages extending to the negative rail (VEE), including 0V in single-supply operation. This rail-to-rail input capability enables direct coupling of baseband video signals without level-shifting circuitry. Performance remains specified down to VEE, with no phase reversal or latch-up-critical for maintaining sync pulse integrity in composite video applications using the MAX4314ESD+.
Can multiple MAX4314ESD+ devices be connected in parallel for larger switch matrices?
Yes, multiple MAX4314ESD+ devices can be safely paralleled by tying their outputs together and controlling each device's SHDN pin independently. When disabled, the MAX4314ESD+ output enters a high-impedance state (typical 35kΩ), preventing contention. This architecture enables scalable 8:1, 12:1, or N:1 video switching matrices without external isolation diodes or buffers-leveraging the inherent shutdown behavior of the MAX4314ESD+.
