INDUSTRIAL TEMPERATURE RANGE
QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS 12-BIT 3-TO-1 BUS-SELECT SWITCH
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 inputs Available in SSOP and TSSOP packages
IDTQS316214
DESCRIPTION:
APPLICATIONS:
· Video, audio, graphics switching, muxing · Hot-swapping, hot-docking · Voltage translation (5V to 3.3V)
The QS316214 provides a set of twelve high-speed CMOS TTLcompatible buses switching between three separate ports. The low ON resistance of the QS316214 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The device operates as a 12-bit bus-select through the data-select (S0-S2) terminals. Mux/Demux devices provide an order of magnitude faster speed than equivalent logic devices. The QS316214 is characterized for operation at -40°C to +85°C.
