IDTQS3L384 HIGH-SPEED LOW POWER 10-BIT BUS EXCHANGE SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH PRODUCTS IDTQS3L384 HIGH-SPEED LOW POWER CMOS 10-BIT BUS EXCHANGE SWITCH FEATURES: DESCRIPTION: Enhanced N channel FET with no inherent diode to Vcc The QS3L384 provides a set of ten high-speed CMOS TTL-compatible 5 bidirectional switches connect inputs to outputs bus switches. The low ON resistance of the QS3L384 allows inputs to be Zero propagation delay, zero added ground bounce connected to outputs without adding propagation delay and without gener- Ultra low power with 0.2A typical Icc ating additional ground bounce noise. The Bus Enable (BE) signals turn the Undershoot clamp diodes on all switch and control inputs switches on. Two bus enable signals are provided, one for each of the upper Two enables control five bits each and lower five bits of the two 10-bit buses. Available in QSOP and TSSOP packages The QS3L384 is characterized for operation at -40C to +85C. APPLICATIONS: Hot-swapping, hot-docking Voltage translation (5V to 3.3V) Power Conservation Capacitance reduction and isloation Bus Isolation Clock Gating FUNCTIONAL BLOCK DIAGRAM A0 B0 A4 B4 A5 B5 A9 B5 BEA BEB The IDT logo is a registered trademark of Integrated Device Technology, Inc.
