Technical content
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/H9024 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 power dissipation of the device when loaded must be designed to keep the device junction temperature below T JMAX. *During power-up and power-down, these voltage ratings require an appropriate sequence of applying and removing signals and power supplies.
