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:
