Product details
Overview
The MAX465CNG from Maxim Integrated is a triple-channel, 3P2T RGB video switch and buffer with 2V/V fixed-gain amplifiers, ±5V dual-supply operation, 90MHz bandwidth, 0.01%/0.03° differential gain/phase error, and 20ns channel switching time-designed for broadcast-quality RGB multiplexing in color video overlay editors and medical imaging systems.
For engineers reviewing the MAX465CNG datasheet, MAX465CNG pinout, MAX465CNG application, or MAX465CNG equivalent, this page delivers verified electrical specs, package-confirmed pin functions, real-world crosstalk and isolation performance at 10MHz, and validated alternatives for 75Ω back-terminated coaxial cable driving applications.
Technical Context
The MAX465CNG integrates three independent 2V/V gain amplifiers with high-speed SPDT analog switches, each featuring bipolar construction for 5pF input capacitance (on/off), 250kΩ disabled output resistance for MAX463/MAX464 variants but only 1kΩ for MAX465/MAX466 due to internal feedback resistor topology, and logic-controlled channel selection via CS/A0/EN/LE interface.
It operates across ±4.75V to ±5.25V supplies, supports ±2.5V output swing into 150Ω and ±2V into 75Ω, achieves 300V/µs slew rate at 2V/V gain, and maintains <60dB adjacent-channel crosstalk and >70dB off-isolation at 10MHz with all inputs driven-critical for maintaining RGB signal integrity in multi-source video routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Configuration | Fixed 2V/V amplifier gain-enables unity gain at coaxial cable output when driving 75Ω back-terminated lines. |
| −3dB Bandwidth | 90MHz at 2V/V gain-supports full HD RGB signals without high-frequency roll-off. |
| Differential Gain/Phase Error | 0.01% / 0.03°-meets broadcast-quality color fidelity requirements for RGB medical imaging and security systems. |
| Channel Switching Time | 20ns-ensures glitch-free source transitions in real-time video editing and overlay applications. |
| Input Capacitance | 5pF (on or off)-minimizes source impedance interaction and preserves signal bandwidth up to 100MHz. |
| Output Swing | ±2V into 75Ω, ±2.5V into 150Ω-drives standard video loads directly without external level-shifting. |
| Supply Voltage Range | ±4.75V to ±5.25V-compatible with standard ±5V analog video rails and tolerant of rail variation. |
Pinout & Package
MAX465CNG is housed in a 24-pin narrow plastic DIP (0°C to +70°C temperature range), with GND, V+, and V− pins distributed for low-noise analog layout and thermal dissipation. Pin spacing follows JEDEC MS-001 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0A, IN1A, IN2A | Analog Input Channel A (RGB) | Accepts R/G/B baseband signals for first switch path; AC-grounded by adjacent GND pins to suppress crosstalk. |
| IN0B, IN1B, IN2B | Analog Input Channel B (RGB) | Accepts alternate R/G/B source set; isolated via GND/V+/V− guard rings to maintain >60dB inter-channel rejection. |
| OUT0, OUT1, OUT2 | Buffered Analog Output (RGB) | 2V/V gain outputs drive 75Ω coax directly; output impedance ≤5Ω ensures minimal mismatch loss. |
| V+, V− | Positive/Negative Supply Rails | ±5V dual supplies power amplifiers and switches; multiple V− pins serve as thermal conduction paths from die. |
| GND (pins 1,3,5,11,13,19) | Analog Ground Reference | Distributed ground pins surround analog inputs to form low-inductance return paths and reduce parasitic coupling. |
| CS, A0, EN, LE | Digital Control Interface | TTL-compatible logic inputs configure channel select (A0), latch enable (LE), chip select (CS), and buffer enable (EN). |
Key Features
| Feature | Design Value |
|---|---|
| 2V/V Fixed-Gain Amplifiers | Enables unity gain at 75Ω cable end without external resistors-reducing component count and layout complexity in RGB line drivers. |
| 20ns Channel Switching | Minimizes visible artifacts during real-time RGB source switching in broadcast switchers and video editors. |
| 5pF Input Capacitance | Maintains flat frequency response up to 100MHz even with 250Ω source impedances-critical for preserving edge integrity in digital video timing. |
| Logic Disable Mode | Drives outputs to high-Z with 1kΩ typical disabled resistance-allows safe paralleling of up to two MAX465CNG devices in larger mux arrays. |
| AC-Grounded Input Structure | Adjacent GND/V+/V− pins around all analog inputs suppress >60dB crosstalk-essential for maintaining color fidelity in RGB overlay systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RGB video switch and buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX465CWG | Same electrical specs and 2V/V gain, but in 24-pin wide SO package with −40°C to +85°C operating range. | Suitable for industrial video encoders requiring extended temperature tolerance and surface-mount assembly. | Select MAX465CWG when board space constraints favor SOIC or ambient conditions exceed +70°C. |
| MAX466CWG | Quad-channel variant (4× 2V/V buffers) in same 24-pin wide SO package; shares identical gain, bandwidth, and error specs. | Used where fourth RGB+Sync or auxiliary video channel is required-e.g., RGB+HS/VS multiplexing. | Choose MAX466CWG only when four buffered outputs are needed; pinout differs and is not drop-in compatible. |
Compared with MAX465CNG, MAX465CWG offers identical performance in a surface-mount package with wider temperature range, while MAX466CWG adds a fourth channel at the cost of non-interchangeable pinout-neither is pin-compatible, but both share the same gain architecture and video fidelity metrics.

FAQ
What is the maximum load capacitance the MAX465CNG can drive without oscillation?
The MAX465CNG is internally compensated for stable operation with capacitive loads up to 50pF. For loads exceeding 50pF, an isolation resistor (e.g., 12Ω) must be placed in series between the output and the load, as documented in Figure 3a of the datasheet. This prevents phase-margin degradation and ensures reliable step response in RGB video line-driving applications using the MAX465CNG.
Does the MAX465CNG support TTL-level digital control inputs?
Yes, the MAX465CNG accepts TTL-compatible logic levels: VIH = 2V minimum and VIL = 0.8V maximum for CS, A0, EN, and LE inputs. These thresholds ensure reliable interfacing with standard microcontrollers and FPGA I/O banks without level-shifting circuitry-critical for clean digital control of RGB channel selection and buffer enable/disable states in the MAX465CNG.
Can multiple MAX465CNG devices be paralleled for higher-channel-count RGB muxing?
Up to two MAX465CNG devices may be safely paralleled due to their 1kΩ typical disabled output resistance, which limits loading effects when outputs are high-Z. For larger arrays, use MAX463/MAX464 (250kΩ disabled resistance) instead. Paralleling requires 22Ω isolation resistors per output and careful layout to avoid signal degradation-details are specified in the Applications Information section of the MAX465CNG datasheet.
What is the guaranteed output voltage swing of the MAX465CNG into a 75Ω load?
The MAX465CNG guarantees ±2.0V minimum output swing into a 75Ω load at ±5V supplies, with typical performance reaching ±2.4V. This meets SMPTE and EBU standards for RGB line driving and ensures sufficient headroom for sync pulses and blanking intervals-directly supporting compliant RGB video transmission without external amplification in the MAX465CNG design.
How does the MAX465CNG achieve low differential phase error in RGB applications?
The MAX465CNG achieves 0.03° differential phase error through bipolar amplifier design, 5pF input capacitance, and optimized internal feedback networks-all validated using Tektronix VM700 test methodology. This precision preserves chrominance timing relationships across R/G/B channels, preventing hue distortion in color-critical applications such as medical imaging and broadcast production where the MAX465CNG is deployed.
