4:1 HIGH SPEED MULTIPLEXER
ZXFV301
DEVICE DESCRIPTION
FEATURES AND BENEFITS
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
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 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.

**The thermal resistance from the semiconductor die to ambient is typically 120ЊC/W when the SO16 package is
mounted on a PCB in free air. The power dissipation of the device when loaded must be designed to keep the
device junction temperature below TJMAX.
*During power-up and power-down, these voltage ratings require an appropriate sequence of applying and
removing signals and power supplies.
