IDTQS316292 HIGH-SPEED CMOS 12-BIT 2:1 MUX/DEMUX SWITCH WITH TERMINATION
INDUSTRIAL TEMPERATURE RANGE
QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS 12-BIT 2:1 MUX/ DEMUX SWITCH WITH RESISTOR TERMINATION ON THE DEMUX SIDE
FEATURES:
- - - - - - Enhanced N channel FET with no inherent diode to Vcc 5 bidirectional switches connect inputs to outputs Zero propagation delay, zero ground bounce TTL-compatible input and output levels Undershoot clamp diodes on all switch and control pins Available in 56-pin SSOP and TSSOP Packages
IDTQS316292
DESCRIPTION:
The QS316292 is a high-speed CMOS12-bit 2:1 multiplexer/demultiplexer switch with a 500 resistor termination to GND on the demultiplexer side to eliminate floating nodes. The low ON resistance of the QS316292 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The QS316292 is characterized for operation at -40°C to +85°C.
APPLICATIONS
- - - Resource sharing Hot-docking Voltage translation (5V to 3.3V)
