4:1 HIGH SPEED MULTIPLEXER
ZXFV302
DEVICE DESCRIPTION
FEATURES AND BENEFITS
The ZXFV302 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
high speed high output current capability provides 75⍀
cable drive for use in high performance video
applications.
The input channel is selected by means of two logic
lines using an internal decoder. An output enable line
allows expansion to eight channels using two devices
ZXFV302 as shown in the example application figure 1.
An alternative device, ZXFV301 provides the same
functionality and pin-out as the ZXFV302 but with four
separate logic lines controlling the switch channels
directly.
