Product details
Overview
The MAX4111CSA from Maxim Integrated is a single-pole, single-throw (SPST) buffered video switch optimized for broadcast-quality composite and RGB video routing. It delivers 330MHz -3dB bandwidth, 0.1dB gain flatness to 150MHz, 700V/µs slew rate, ±0.01° differential phase error, and ultra-low 13mVp-p switching glitch-enabling high-fidelity signal path selection in HDTV and NTSC/PAL video crosspoint arrays.
For engineers reviewing the MAX4111CSA datasheet, MAX4111CSA pinout, MAX4111CSA application, or MAX4111CSA equivalent, key selection criteria include its ±5V dual-supply operation, high-Z output disable state, 3pF input capacitance, 20Ω output resistance, and compatibility with 75Ω video termination schemes in multi-channel routing systems.
Technical Context
The MAX4111CSA employs an open-loop buffer architecture with make-before-break switching to minimize transient glitches while maintaining stability into capacitive loads up to 47pF. Its complementary bipolar process ensures low input capacitance (3pF) and constant high input impedance independent of channel state.
It operates as a transparent analog switch: digital control (EN pin) directly enables/disables the signal path without latching, and output impedance remains stable at ~20Ω across frequency (DC–330MHz), supporting direct drive into 5kΩ resistive or 75Ω coaxial loads without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 330MHz - supports full HD (1080i/p) baseband video without attenuation |
| Gain Flatness | 0.1dB to 150MHz - preserves color fidelity and luminance integrity in NTSC/PAL/SECAM signals |
| Slew Rate | 700V/µs - ensures distortion-free switching of fast-rising sync pulses and active video edges |
| Differential Phase/Gain | 0.01° / 0.01% - meets broadcast-grade timing accuracy for chroma/luma separation |
| Switching Glitch | 13mVp-p, positive polarity - avoids misinterpretation as negative sync pulse in composite video |
| Disabled Output State | High-impedance, 30MΩ || 5pF - prevents signal leakage and crosstalk in unselected paths |
| Supply Current | 5.5mA max operating / 250µA disabled - enables low-power array standby modes |
Pinout & Package
MAX4111CSA is housed in an 8-pin narrow SO package (SOIC-N, 150-mil width), compliant with JEDEC MS-012, with 1.27mm pitch and 4.9mm × 3.9mm body dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable Control Input | Active-high logic input; drives output to high-Z when low, reducing supply current to 250µA |
| 2 (VCC) | Positive Supply | +5V (±4.5V to ±5.5V range); requires local 0.1µF + 1000pF bypassing |
| 3 (OUT) | Analog Output | Buffered, low-impedance (20Ω) video output; DC-coupled, 75Ω-terminable |
| 4 (VEE) | Negative Supply | −5V (±4.5V to ±5.5V range); symmetric dual supply enables rail-to-rail video swing |
| 5 (N.C.) | No Connect | Not internally bonded; must remain unconnected per datasheet |
| 6 (GND) | Analog Ground | Noise-sensitive reference for input/output; requires dedicated low-impedance ground plane |
| 7 (IN) | Analog Input | High-impedance (100MΩ), low-capacitance (3pF) video input; accepts ±2.5V p-p signals |
| 8 (GND) | Analog Ground | Second ground pin for improved PSRR and reduced ground bounce in high-frequency operation |
Key Features
| Feature | Design Value |
|---|---|
| Make-before-break switching | Eliminates signal dropout during channel transitions in multi-switch arrays |
| Open-loop buffer architecture | Stable operation into 47pF capacitive loads without external compensation |
| Constant high input impedance | 100MΩ across temperature and switching states, preventing loading of upstream sources |
| Ultra-low crosstalk | −92dB at 30MHz ensures isolation between adjacent channels in dense PCB layouts |
| Positive-polarity switching glitch | 13mVp-p pulse avoids false triggering of sync detectors expecting negative-going sync edges |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST video switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8174ARZ | 4-channel, 500MHz bandwidth, ±15V supplies, higher power (12mA/channel) | Integrated quad architecture reduces board space but lacks per-channel disable | Prefer AD8174ARZ for compact multi-channel routing where disable function is not required |
| TS3V330PW | Single 3.3V SPST, 350MHz bandwidth, CMOS process, no dual supply support | Lower voltage operation suits portable video gear but cannot handle ±2.5V composite swing | Choose TS3V330PW only for 3.3V systems with DC-coupled low-voltage video signals |
Compared with MAX4111CSA, AD8174ARZ offers higher bandwidth and integration but sacrifices per-channel disable and dual-supply flexibility; TS3V330PW provides lower-voltage compatibility but lacks the ±5V headroom needed for broadcast-level signal integrity.

FAQ
What is the maximum video signal amplitude supported by the MAX4111CSA?
The MAX4111CSA supports analog input voltages from (VEE − 0.3V) to (VCC + 0.3V), with specified operation over ±2.5V p-p at ±5V supplies. This accommodates standard composite video (1V p-p), RGB (0.7V p-p), and YPbPr (0.7V p-p) signals while preserving linearity and minimizing distortion. The ±2.5V input range ensures headroom for sync tips and blanking intervals without clipping.
Does the MAX4111CSA require external termination resistors?
Yes-the MAX4111CSA output is designed to drive 75Ω coaxial video lines and requires external 75Ω termination at the load end to prevent reflections and maintain signal integrity above 100MHz. Its 20Ω output resistance is intentionally low to support this configuration without added series resistance, and the device itself does not integrate internal termination.
Can the MAX4111CSA operate from a single supply?
No-the MAX4111CSA requires dual ±5V supplies (±4.5V to ±5.5V range) to support rail-to-rail video signal swing and maintain specified differential phase/gain performance. Single-supply operation is not supported; attempting to bias inputs/outputs for single-rail use degrades AC specifications and violates absolute maximum ratings for analog input voltage.
What is the purpose of the two GND pins on the MAX4111CSA?
The MAX4111CSA features two separate GND pins (pins 6 and 8) to provide independent low-inductance return paths for input and output circuitry, reducing ground bounce and improving PSRR above 10MHz. Layout best practice requires connecting both pins to a solid, low-impedance analog ground plane-not daisy-chained-to preserve 330MHz bandwidth and minimize crosstalk.
How does the MAX4111CSA achieve ultra-low switching glitch?
The MAX4111CSA achieves 13mVp-p switching glitch through make-before-break switching topology combined with proprietary complementary bipolar process design that minimizes charge injection and clock feedthrough. The glitch is intentionally positive-polarity to avoid confusion with negative sync pulses in composite video, and its amplitude remains stable across temperature and supply voltage variations.
