Product details
Overview
MAX4221CSE from Maxim Integrated is a dual, 2-input, single-output buffered video switch optimized for broadcast-quality composite and RGB video routing. It delivers -3dB bandwidth of 330MHz, 0.1dB gain flatness to 150MHz, and ultra-low switching glitch of 13mVp-p (positive polarity), enabling high-fidelity signal path selection in HDTV crosspoint arrays.
For engineers reviewing the MAX4221CSE datasheet, MAX4221CSE pinout, MAX4221CSE application, or MAX4221CSE equivalent, this device supports precise analog video multiplexing with differential phase/gain error of only 0.01°/0.01%, high-Z outputs when disabled, and robust crosstalk rejection (-92dB at 30MHz) - critical for multi-channel broadcast infrastructure design.
Technical Context
The MAX4221CSE implements a make-before-break switching architecture with open-loop unity-gain buffer amplifiers, enabling stable operation into capacitive loads without oscillation. Its complementary bipolar process yields low input capacitance (3pF) and dynamic output resistance (~20Ω), supporting wideband video signals up to 330MHz.
It features two independent SPDT switch channels (OUT0/OUT1), each controlled by dedicated 2-bit logic inputs (SEL0/SEL1 for OUT0; SEL2/SEL3 for OUT1), with no internal latches - all digital inputs are transparent. Supply operation is specified across ±4.5V to ±5.5V, with rail-to-rail analog input range of ±2.5V.
Key Specifications

| 12, 14 | SEL0, SEL1 | Channel select bits for OUT0 (00=IN0, 01=IN1, 1X=high-Z) |
| 15, 16 | SEL2, SEL3 | Channel select bits for OUT1 (00=IN2, 01=IN3, 1X=high-Z) |
| 13 | VCC | +5V analog supply; requires local 0.1µF + 1000pF bypassing |
| 7 | VEE | -5V analog supply; symmetric dual-rail operation essential for AC-coupled video swing |
Key Features
| Feature | Design Value |
|---|---|
| Make-before-break switching | Reduces inter-channel switching noise and prevents momentary signal dropout in live video arrays |
| Constant high input impedance | 30MΩ input resistance with 3pF capacitance minimizes loading on upstream drivers and preserves source integrity |
| High-Z output disable | Outputs enter tri-state mode with <250µA quiescent current, enabling modular expansion of crosspoint matrices |
| Glitch polarity control | Positive-only 13mVp-p transient avoids false triggering of sync detection circuits in NTSC/PAL receivers |
| Open-loop buffer architecture | Drives ≥5pF load capacitance without compensation or instability - simplifies layout in high-speed video paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffered video switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4222CSE | Same pinout and electrical specs, but rated for -40°C to +85°C industrial temperature range | Required for outdoor broadcast enclosures or industrial video processing where extended thermal margin is needed | Select MAX4222CSE when operating ambient exceeds +70°C or requires AEC-Q200-aligned reliability testing |
| AD8170ARUZ | Single 2:1 video switch (8-pin), 320MHz bandwidth, 0.02°/0.02% differential phase/gain, ±5V supplies | Lacks dual-channel integration; requires two devices to match MAX4221CSE's functionality | Choose AD8170ARUZ for space-constrained designs where board area permits discrete channel replication |
Compared with MAX4221CSE, MAX4222CSE offers identical performance with extended temperature support, while AD8170ARUZ provides comparable bandwidth and accuracy in a smaller footprint but requires duplication for dual-channel use - impacting BOM count, layout complexity, and inter-channel matching.

FAQ
What is the operating temperature range for MAX4221CSE?
The MAX4221CSE is specified for operation from 0°C to +70°C. This commercial-grade temperature range aligns with standard studio equipment and indoor broadcast infrastructure environments. The 'C' suffix in MAX4221CSE explicitly denotes this 0°C to +70°C rating, distinct from industrial variants like MAX4222CSE (-40°C to +85°C). Thermal derating begins above +70°C, with 8.70mW/°C reduction in power dissipation for the 16-pin narrow SO package.
Does MAX4221CSE support DC-coupled video signals?
Yes, MAX4221CSE supports DC-coupled video signals within its specified analog input voltage range of ±2.5V. Its ±5V dual-supply architecture and rail-to-rail input stage enable accurate transmission of sync-on-green, RGBHV, or other DC-balanced video formats without clamping or level-shifting circuitry. Input common-mode range extends to VEE − 0.3V and VCC + 0.3V, ensuring robustness against transient overdrive conditions typical in professional video interfaces.
How does the make-before-break switching in MAX4221CSE reduce video artifacts?
The make-before-break switching in MAX4221CSE briefly connects both inputs before disconnecting the previous one, eliminating momentary open-circuit gaps that cause visible "glitch bars" or "dropout" in live video. This architecture, combined with ultra-low 13mVp-p positive-polarity transient, prevents sync pulse interference and maintains continuous signal flow - critical for frame-accurate switching in broadcast production switchers and real-time video processors using MAX4221CSE.
Can MAX4221CSE drive 75Ω coaxial cables directly?
MAX4221CSE is not designed for direct 75Ω cable driving; it specifies a 5kΩ load for full AC performance. Driving 75Ω requires external series termination or a dedicated line driver (e.g., MAX4352) to prevent bandwidth degradation and reflections. However, its 20Ω dynamic output resistance and 330MHz bandwidth allow clean interfacing with properly terminated 75Ω paths when used with appropriate output buffering - a configuration validated in Maxim's Figure 6 8×2 multiplexer reference design using MAX4221CSE.
What is the function of the multiple GND pins on MAX4221CSE?
MAX4221CSE features seven dedicated GND pins (pins 1, 3, 5, 7, 11, 13, and the exposed pad in some variants) to minimize ground impedance and isolate analog return currents. This multi-pin grounding strategy reduces shared-impedance coupling between input, output, and power sections - essential for maintaining -92dB crosstalk and preventing ground-bounce-induced distortion in high-density video routing arrays built with MAX4221CSE.
