-3dB Bandwidth of 330MHz  
The MAX4111/MAX4121/MAX4221 wid e b a nd vid e o  
switches are optimized for high-definition, broadcast-  
quality, composite (HDTV, NTSC, PAL, SECAM, and  
RGB) video switching arrays. Their open-loop buffer  
amplifiers offer 0.1dB gain flatness to 150MHz. They  
op e ra te from ± 5V s up p lie s a nd fe a ture d iffe re ntia l  
phase and gain error of only 0.01°/0.01%, respectively.  
The ultra -low switc hing glitc h (13mV) is p ositive to  
avoid confusion with any sync pulse.  
0.1dB Gain Flatness of 150MHz  
700V/µs Slew Rate  
0.01°/0.01% Differential Phase/Gain  
Low Power: 5.5mA Max  
Ideal as building blocks in large arrays, these devices  
feature a constant, high input impedance and a disable  
function that puts the outputs into a high-impedance  
state and reduces the operating current to only 250µA.  
The open-loop architecture allows the outputs to drive  
capacitive loads without oscillation. Other key features  
include -92dB crosstalk and -78dB isolation (MAX4121).
