IDTQS34XVH245 INDUSTRIAL TEMPERATURE RANGE 2.5V / 3.3V 32-BIT HIGH BANDWIDTH BUS SWITCH QUICKSWITCH PRODUCTS IDTQS34XVH245 2.5V / 3.3V 32-BIT HIGH BANDWIDTH BUS SWITCH FEATURES: DESCRIPTION: N channel FET switches with no parasitic diode to VCC The QS34XVH245 HotSwitch is a high bandwidth 32-bit bus switch. The Isolation under power-off conditions QS34XVH245 has very low ON resistance, resulting in under 250ps No DC path to VCC or GND propagation delay through the switch. The switches can be turned ON 5V tolerant in OFF and ON state under the control of individual LVTTL-compatible Output Enable (OEx) 5V tolerant I/Os signals for bidirectional data flow with no added delay or ground bounce. In Low RON , 4 typical the ON state, the switches can pass up to 5V. In the OFF state, the switches Flat RON characteristics over operating range offer very high impedence at the terminals. Rail-to-rail switching 0 - 5V The combination of near-zero propagation delay, high OFF impedance, Bidirectional dataflow with near-zero delay: no added ground and over-voltage tolerance makes the QS34XVH245 ideal for high perfor- bounce mance communications applications. Excellent RON matching between channels The QS34XVH245 is characterized for operation from -40C to +85C. VCC operation: 2.3V to 3.6V High bandwidth - up to 500MHz LVTTL-compatible control Inputs Undershoot Clamp Diodes on all switch and control Inputs Low I/O capacitance, 4pF typical Available in 80-pin QVSOP package APPLICATIONS: Hot-swapping 10/100 Base-T, Ethernet LAN switch Low distortion analog switch Replaces mechanical relay ATM 25/155 switching FUNCTIONAL BLOCK DIAGRAM A0 A1 A2 A3 A4 A5 A6 A7 A1 A17 A18 A19 A20 A21 A22 A23 6 OE1 OE3 B1 B17 B18 B19 B20 B21 B22 B23 B0 B1 B2 B3 B4 B5 B6 B7 6 A8 A9 A10 A11 A12 A13 A14 A15 A2 A25 A26 A27 A28 A29 A30 A31 4 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.
