Product details
Overview
MAX4312GEE+TB5C from Maxim Integrated is an 8-channel, unity-gain-stable video multiplexer-amplifier optimized for broadcast-quality signal routing. It delivers 265MHz -3dB bandwidth, 345V/µs slew rate, 40ns channel switching time, and 0.06%/0.08° differential gain/phase error, enabling high-fidelity SD/HD video switching in professional AV equipment.
For engineers reviewing the MAX4312GEE+TB5C datasheet, MAX4312GEE+TB5C pinout, MAX4312GEE+TB5C application, or MAX4312GEE+TB5C equivalent, key selection criteria include rail-to-rail output swing into 150Ω, input common-mode range extending to VEE, low 10mVp-p switching transients, and shutdown current of 560µA - all critical for compact, low-power video matrix designs.
Technical Context
The MAX4312GEE+TB5C integrates an 8-input analog multiplexer with a unity-gain-stable voltage-feedback amplifier, supporting closed-loop gains ≥+1V/V via external feedback resistors. Its architecture enables simultaneous optimization of switching speed (40ns), transient suppression (10mVp-p), and video fidelity (0.06% DG/0.08° DP).
It operates from single +4V to +10.5V or dual ±2V to ±5.25V supplies, features rail-to-rail outputs driving 150Ω within 730mV of rails, and maintains 8Ω open-loop output impedance across full voltage range - minimizing load-dependent gain error and bandwidth variation.

Pinout & Package
MAX4312GEE+TB5C is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.635mm pitch), optimized for high-density video routing layouts with thermal efficiency and EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1, A2 | Channel address inputs | 3-bit binary select for 8 analog inputs; TTL/CMOS compatible with VIL ≤ VEE+1V, VIH ≥ VCC–1V |
| SHDN | Active-low shutdown control | Pulls output to high-impedance state and reduces ICC to 560µA when < VIL |
| VCC, VEE | Positive/negative supply pins | Support single-supply (4V–10.5V) or dual-supply (±2V–±5.25V) operation; VEE = GND in single-supply mode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video multiplexer-amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4312EEE+ | Same die, identical electrical specs, 16-pin QSOP package without tape-and-reel marking | No functional difference; differs only in packaging format and reel labeling | Select MAX4312EEE+ for manual prototyping or small-batch assembly where tape-and-reel is unnecessary |
| THS4521IDGKR | Single-channel, fully differential amplifier; no integrated multiplexer; 2GHz GBW vs. 265MHz | Requires external analog switches; suited for precision differential signaling, not multichannel video routing | Choose THS4521IDGKR only when differential I/O, ultra-high bandwidth, or DC-coupled operation is mandatory |
Compared with MAX4312EEE+, the MAX4312GEE+TB5C offers identical performance but includes tape-and-reel packaging for automated SMT placement; versus THS4521IDGKR, it provides integrated 8:1 switching and video-optimized distortion specs at lower cost and board area for broadcast routing applications.

FAQ
What is the maximum operating supply voltage for the MAX4312GEE+TB5C?
The MAX4312GEE+TB5C supports a single-supply range of +4V to +10.5V or dual supplies of ±2V to ±5.25V. Absolute maximum supply voltage is 12V (VCC to VEE). Exceeding this risks permanent damage. Operation at 10.5V enables full output swing into 150Ω loads while maintaining specified AC performance including 265MHz bandwidth and 0.06% differential gain error in the MAX4312GEE+TB5C.
Does the MAX4312GEE+TB5C require external gain-setting resistors?
Yes, the MAX4312GEE+TB5C uses external feedback (RF) and gain-setting (RG) resistors to configure closed-loop gains ≥+1V/V. Unlike the fixed +2V/V MAX4313–MAX4315 variants, the MAX4312GEE+TB5C's amplifier is unity-gain stable and relies on external resistors for gain control. Recommended values (e.g., 500Ω RF/RG for +2V/V) are documented in the MAX4312GEE+TB5C datasheet to optimize bandwidth and stability.
What is the input capacitance of the MAX4312GEE+TB5C multiplexer channels?
The MAX4312GEE+TB5C exhibits a constant 2pF input capacitance on all IN0–IN7 channels, whether selected or unselected. This design eliminates variable loading on source drivers and ensures predictable signal integrity across switching events - a critical feature for maintaining flat frequency response in multi-source video systems using the MAX4312GEE+TB5C.
Can the MAX4312GEE+TB5C drive 75Ω coaxial cables directly?
Yes, the MAX4312GEE+TB5C can drive 75Ω coaxial cables when used with proper back-termination. Its rail-to-rail output swings to within 730mV of VCC into 150Ω (equivalent to two 75Ω terminations), and its low 8Ω open-loop output impedance minimizes gain error under load. For optimal performance, use surface-mount 75Ω termination resistors placed adjacent to the MAX4312GEE+TB5C OUT pin as specified in the MAX4312GEE+TB5C evaluation guidelines.
How does the shutdown function affect output impedance in the MAX4312GEE+TB5C?
When SHDN is pulled low, the MAX4312GEE+TB5C places its output in a high-impedance state with typical disabled output resistance of 35kΩ, while reducing supply current to 560µA. This allows safe paralleling of multiple MAX4312GEE+TB5C outputs in large switch matrices - only the enabled device drives the bus, preventing contention. The high-Z state is fully specified and tested across temperature for reliable system-level implementation in the MAX4312GEE+TB5C.
