IDTQS32390

HIGH-SPEED CMOS QUICKSWITCH

16:8 MULTIPLEXER

DESCRIPTION:

The QS32390 provides a 16:8 multiplexer logic switch. The QS32390 has

an internal 25

Ω resistor to reduce reflection noise in high-speed applica-

tions. 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.
