ZXFV301N16TA

DEVICE DESCRIPTION
The ZXFV301 is a 4:1 high speed analog switch
designed for use as a buffered video multiplexer and
other high-speed applications.
It features low different gain and phase distortion. The
highspeedhighoutputcurrentcapabilityprovides75
cable drive for use in high performance video
applications.
The input channel is selected by means of four logic
lines. An output enable line allows expansion to eight
channels using two devices ZXFV301 as shown in the
example application figure 1.
An alternative device, ZXFV302 has a seperate
datasheet and provides the same functionality and
pin-out as the ZXFV301 but with only two logic lines
controlling the switch via a decoder.
