MAX4221EVKIT-SO

P1-P3P4-P6P7-P9P10-P12
_______________General Description
The MAX4111/MAX4121/MAX4221 wideband video
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
operate from ±5V supplies and feature differential
phase and gain error of only 0.01°/0.01%, respectively.
The ultra-low switching glitch (13mV) is positive to
avoid confusion with any sync pulse.
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).
The MAX4111/MAX4121/MAX4221 are offered in nar-
row plastic DIP and SO packages. See the table below
for key features:

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
