Product details
Overview
The MAX463CWG from Maxim Integrated is a triple-channel RGB video switch and buffer with unity-gain amplifiers, ±5V dual-supply operation, 100MHz bandwidth, 20ns channel switching time, and ±2V output swing into 75Ω - designed for broadcast-quality RGB multiplexing in professional video routing systems.
For engineers reviewing the MAX463CWG datasheet, MAX463CWG pinout, MAX463CWG application, or MAX463CWG equivalent, this page delivers verified specifications, exact pin functions, real-world video system use cases, and validated alternative options for RGB signal path design and component sourcing.
Technical Context
The MAX463CWG integrates three independent analog channels, each with a unity-gain-stable amplifier and high-speed SPDT switch controlled via TTL-compatible digital inputs (CS, A0, EN, LE). Its bipolar construction yields only 5pF input capacitance-on or off-minimizing source loading and switching transients across RGB signal paths.
It supports logic-controlled channel selection and amplifier enable/disable with high-Z outputs in disabled mode, achieving >60dB adjacent-channel crosstalk and 70dB off-isolation at 10MHz. All analog inputs are surrounded by AC-ground pins (GND/V+/V−) to suppress parasitic coupling critical for color fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 100MHz at unity gain - preserves full RGB video bandwidth up to 1080p/60 without attenuation. |
| Channel Switching Time | 20ns - enables fast frame-accurate RGB source switching in broadcast switchers. |
| Differential Gain/Phase Error | 0.01%/0.03° - meets broadcast-quality color fidelity requirements for NTSC/PAL composite overlays. |
| Output Swing | ±2V into 75Ω - drives back-terminated coaxial cable directly without external level-shifting. |
| Input Capacitance | 5pF (channel on or off) - eliminates impedance discontinuity during switching, preventing ghosting or timing skew. |
| Supply Voltage Range | ±4.75V to ±5.25V - compatible with standard ±5V video system rails and tolerant of rail variation. |
| Disabled Output Resistance | 250kΩ typical - allows safe paralleling of multiple MAX463CWG devices for larger RGB mux arrays. |
Pinout & Package
MAX463CWG is housed in a 24-pin wide SOIC (SO) package with exposed thermal pad on V− pins for enhanced power dissipation in continuous video buffering applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0A, IN1A, IN2A | Analog Input Channel A (RGB) | Accepts R/G/B signals for first input set; isolated by GND/V+/V− pins to minimize crosstalk. |
| IN0B, IN1B, IN2B | Analog Input Channel B (RGB) | Accepts alternate R/G/B sources; identical layout symmetry ensures matched phase response across RGB paths. |
| OUT0, OUT1, OUT2 | Buffered Analog Output (R/G/B) | Unity-gain buffered outputs drive 75Ω coax directly; ±2V swing supports 1VP–P video with headroom. |
| V+, V− | Positive/Negative Supply Rails | ±5V dual supplies; V− pins serve as thermal conduction path - must connect to large copper plane. |
| GND (pins 1,3,5,11,13,19) | Analog Ground Reference | Multiple dedicated GND pins surround analog inputs to form low-inductance AC ground shield. |
| CS, A0, EN, LE | Digital Control Inputs | TTL-compatible; CS/A0 select channel (A/B), EN enables/disables buffers, LE configures latch behavior. |
Key Features
| Feature | Design Value |
|---|---|
| Triple RGB channel integration | Single-package solution for full R+G+B signal routing - eliminates inter-channel skew and board layout mismatch. |
| 5pF input capacitance (on/off) | Eliminates transient glitches during switching; maintains constant source load for stable driver stage operation. |
| 20ns channel switching time | Enables sub-line switching in high-frame-rate video - suitable for frame-synchronized RGB routing in broadcast infrastructure. |
| High-Z disable mode with 250kΩ output resistance | Permits parallel connection of multiple MAX463CWG units without signal degradation or termination conflicts. |
| AC-grounded analog input layout | Reduces crosstalk to <−60dB - preserves color separation integrity in RGB overlay and medical imaging systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RGB video switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX465CWG | Gain-of-two internal amplifiers (vs. unity gain); same pinout and package. | Designed for driving back-terminated coax where unity gain at cable end is required (e.g., long-haul RGB distribution). | Select MAX465CWG when system uses 75Ω back-termination and requires 2× amplifier gain to compensate for 6dB cable loss. |
| MAX464CWI | Quad-channel (4× RGB) version in 28-pin wide SO; higher channel count, different pinout and footprint. | Used where four independent RGB sources must be routed - not drop-in replaceable due to pin count and layout change. | Choose MAX464CWI only when expanding from triple to quad RGB routing; requires PCB redesign and firmware update for fourth channel. |
Compared with MAX465CWG, the MAX463CWG provides lower gain but superior DC accuracy and simpler gain-setting for direct-drive applications; versus MAX464CWI, it offers identical per-channel performance in a smaller footprint but lacks the fourth channel needed for quad-source systems.

FAQ
What is the operating temperature range for the MAX463CWG?
The MAX463CWG is specified for commercial temperature operation from 0°C to +70°C. This range aligns with controlled-environment video equipment such as studio monitors, broadcast switchers, and medical display controllers where ambient thermal management is assured. The device's electrical characteristics - including 100MHz bandwidth and 0.01% differential gain error - are guaranteed across this full range.
Does the MAX463CWG support back-terminated 75Ω coaxial cable driving?
Yes, the MAX463CWG directly drives 75Ω back-terminated coaxial cable with a guaranteed ±2V output swing. Its unity-gain architecture and 200V/µs slew rate ensure minimal distortion and settling time under 50ns to 0.1%, making it suitable for RGBHV and VGA-level video signals without external level-shifting or gain compensation circuitry.
How does the MAX463CWG achieve low crosstalk in RGB applications?
The MAX463CWG achieves <−60dB adjacent-channel crosstalk by surrounding all analog input pins (IN0A–IN2B) with AC-ground pins - GND, V+, and V− - forming a distributed guard ring. This layout minimizes parasitic coupling between R, G, and B paths, preserving color fidelity in overlay and multiplexing applications where channel isolation is critical.
Can multiple MAX463CWG devices be paralleled for larger RGB multiplexing?
Yes, the MAX463CWG supports safe paralleling in disabled mode due to its 250kΩ typical output resistance. When EN is high, outputs enter high-Z state with negligible loading - enabling scalable RGB mux arrays. Series isolation resistors (e.g., 22Ω) are recommended at each output to dampen capacitive interaction between paralleled units.
What digital interface protocol does the MAX463CWG use for channel selection?
The MAX463CWG uses a simple 3-wire TTL-compatible digital interface: CS (chip select), A0 (channel address), and EN (enable). With LE tied to V+, CS latches both A0 and EN on its rising edge - allowing synchronous, glitch-free channel switching. No clock or serial protocol is required, simplifying FPGA or microcontroller integration in real-time video systems.
