IDTQS3383 HIGH-SPEED CMOS 10-BIT BUS EXCHANGE SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH PRODUCTS IDTQS3383 HIGH-SPEED CMOS 10-BIT BUS EXCHANGE SWITCH DESCRIPTION: FEATURES: Enhanced N channel FET with no inherent diode to Vcc The QS3383 provides ten high-speed CMOS TTL-compatible bus 5 bidirectional switches connect inputs to outputs switches. The low ON resistance of the QS3383 allows inputs to be Zero propagation delay, zero added ground bounce connected to outputs without adding propagation delay and without gener- Undershoot clamp diodes on all switch and control inputs ating additional ground bounce noise. The Bus Enable (BE) signal turns Bus exchange allows nibble swap the switches on. The Bus Exchange (BX) signal provides nibble swap of Available in QSOP package the AB and CD pairs of signals. This exchange configuration allows byte swapping of buses in systems. It can also be used as a 5-wide 2-to-1 multiplexer and to create low delay barrel shifters, etc. The QS3383 is characterized for operation at -40C to +85C. APPLICATIONS: Hot-swapping, hot-docking Voltage translation (5V to 3.3V) Resource sharing Crossbar switching FUNCTIONAL BLOCK DIAGRAM A0 C0 D0 B0 A4 C4 D4 B4 BX BE INDUSTRIAL TEMPERATURE RANGE OCTOBER 2011 1 c 2011 Integrated Device Technology, Inc.
