IDTQS3162214
DESCRIPTION:
The QS3162214 provides a set of twelve high-speed CMOS TTLcompatible buses switching between three separate ports. The device operates as a 12-bit bus-select switch through the data-select (S0-S2) terminals. The QS3162214 adds an internal 25 series termination resistor to reduce reflection noise in high speed applications. When closed, the switch acts as the source (series) termination for the driver connected to it. Mux/Demux devices provide an order of magnitude faster speed than equivalent logic devices. The QS3162214 is characterized for operation at -40°C to +85°C.
APPLICATIONS
- - - Video, audio, graphics switching, muxing Hot-swapping, hot-docking Voltage translation (5V to 3.3V)
