1 / 8 page 1 INDUSTRIAL TEMPERATURE RANGE IDTQS34XVH2245 2.5V / 3.3V 32-BIT HIGH BANDWIDTH BUS SWITCH 2012 Integrated Device Technology, Inc. DSC-5592/14 c INDUSTRIAL TEMPERATURE RANGE DESCRIPTION: The QS34XVH2245 is a high bandwidth, 32-bit bus switch. The QS34XVH2245 with 25 Ω resistance and 1.35ns propagation delay is ideal for line matching and low noise environments. The switches can be turned ON under the control of individual LVTTL-compatible Output Enable (OEx) signals for bidirectional data flow with no added delay or ground bounce. In the ON state, the switches can pass signals up to 5V. In the OFF state, the switches offer very high impedance at the terminals. The combination of small propagation delay, high OFF impedance, and over-voltage tolerance makes the QS34XVH2245 ideal for high performance communications applications. The QS34XVH2245 is characterized for operation from -40 °C to +85 °C. The IDT logo is a registered trademark of Integrated Device Technology, Inc.
