IDTQS32X384

IDTQS32X384 HIGH-SPEED CMOS 20-BIT BUS SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS 20-BIT BUS SWITCH IDTQS32X384 FEATURES: Enhanced N channel FET with no inherent diode to VCC 5Ω bidirectional switches connect inputs to outputs Zero propagation delay Zero ground bounce Undershoot clamp diodes on all switch and control pins Four enables control five bits each TTL-compatible input and output levels Available in 48-pin QVSOP package DESCRIPTION: The QS32X384 provides a set of twenty high-speed CMOS TTLcompatible bus switches. The low ON resistance of the QS32X384 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The Bus Enable (BE) signals turn the switches on. Four Bus Enable signals are provided, one for each of five bits of the 20-bit bus. The ‘384 family of QuickSwitch products is ideal for switching wide digital buses, as well as hotplug buffering, and 5V to 3V conversion. The QS32X384 is characterized for operation at -40°C to +85°C. APPLICATIONS: Hot-swapping, hot-docking Voltage translation (5V to 3.3V) Power conservation Capacitance reduction and isolation Bus isolation Clock gating FUNCTIONAL BLOCK DIAGRAM A0 B0 A10 B10 A4 A5 B4 B5 A14 A15 B14 B15 A9 B9 A19 B19 BEA BEC BED BEB The IDT logo is a registered trademark of Integrated Device Technology, Inc.
