IDTQS34XVH2245 INDUSTRIAL TEMPERATURE RANGE 2.5V / 3.3V 32-BIT HIGH BANDWIDTH BUS SWITCH IDTQS34XVH2245 QUICKSWITCH PRODUCTS 2.5V / 3.3V 32-BIT HIGH BANDWIDTH BUS SWITCH FEATURES: DESCRIPTION: N channel FET switches with no parasitic diode to VCC The QS34XVH2245 is a high bandwidth, 32-bit bus switch. The Isolation under power-off conditions QS34XVH2245 with 25 resistance and 1.35ns propagation delay is No DC path to VCC or GND ideal for line matching and low noise environments. The switches can 5V tolerant in OFF and ON state be turned ON under the control of individual LVTTL-compatible Output 5V tolerant I/Os Enable (OEx) signals for bidirectional data flow with no added delay or Flat RON characteristics over operating range ground bounce. In the ON state, the switches can pass signals up to 5V. Rail-to-rail switching 0 - 5V In the OFF state, the switches offer very high impedance at the Bidirectional dataflow with near-zero delay: no added ground terminals. bounce The combination of small propagation delay, high OFF impedance, Excellent RON matching between channels and over-voltage tolerance makes the QS34XVH2245 ideal for high VCC operation: 2.3V to 3.6V performance communications applications. High bandwidth The QS34XVH2245 is characterized for operation from -40C to LVTTL-compatible control Inputs +85C. Undershoot Clamp Diodes on all switch and control Inputs Low I/O capacitance, 4pF typical 25 resistors for low noise and line matching Available in 80-pin QVSOP package APPLICATIONS: Hot-swapping Low distortion analog switch Replaces mechanical relay ATM 25/155 switching FUNCTIONAL BLOCK DIAGRAM A0 A1 A2 A3 A4 A5 A6 A7 A16 A17 A18 A19 A20 A21 A22 A23 OE1 OE3 B16 B17 B18 B19 B20 B21 B22 B23 B0 B1 B2 B3 B4 B5 B6 B7 A8 A9 A10 A11 A12 A13 A14 A15 A24 A25 A26 A27 A28 A29 A30 A31 OE2 OE4 B24 B25 B26 B27 B28 B29 B30 B31 B8 B9 B10 B11 B12 B13 B14 B15 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
