IDTQS32390
DESCRIPTION:
The QS32390 provides a 16:8 multiplexer logic switch. The QS32390 has an internal 25 resistor to reduce reflection noise in high-speed applications. The enable inputs connect one of two inputs to the common I/O pin, respectively. The multiplexer function can be used to select and route logic signals for zero delay, isolate bus capacitance, form crossbar switches, etc. Mux/Demux devices provide an order of magnitude faster speed than equivalent logic devices. The QS32390 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)
