1 / 8 page 1 INDUSTRIALTEMPERATURERANGE IDTQS3VH2245 2.5V / 3.3V 8-BIT HIGH BANDWIDTH BUS SWITCH 2003 Integrated Device Technology, Inc. DSC-5591/6 c INDUSTRIAL TEMPERATURE RANGE DESCRIPTION: The QS3VH2245 is a high bandwidth 8-bit bus switch. The QS3VH2245, with25 ΩONresistanceand1.35nspropagationdelay,isidealforlinematching andlownoiseenvironments. TheswitchescanbeturnedONunderthecontrol oftheLVTTL-compatibleOutputEnable signalforbidirectionaldataflowwith 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 impedence at theterminals. The combination of small propagation delay, high OFF impedance, and over-voltage tolerance makes the QS3VH2245 ideal for high performance communicationapplications. The QS3VH2245 is characterized for operation from -40 °C to +85°C. The IDT logo is a registered trademark of Integrated Device Technology, Inc. APPLICATIONS: • Hot-swapping • Low distortion analog switch • Replaces mechanical relay • ATM 25/155 switching FEATURES: • N channel FET switches with no parasitic diode to VCC – Isolationunderpower-offconditions – No DC path to VCC or GND – 5V tolerant in OFF and ON state • 5V tolerant I/Os • Flat RON characteristics over operating range • Rail-to-rail switching 0 - 5V • Bidirectional dataflow with near-zero delay: no added ground bounce • Excellent RON matching between channels •VCC operation: 2.3V to 3.6V • High bandwidth • LVTTL-compatible control Inputs • Undershoot Clamp Diodes on all switch and control Inputs • Low I/O capacitance, 4pF typical •25 Ω Ω Ω Ω Ω resistors for low noise and line matching • Available in QSOP and TSSOP packages IDTQS3VH2245 QUICKSWITCH® PRODUCTS 2.5V / 3.3V 8-BIT HIGH BANDWIDTH BUS SWITCH FUNCTIONAL BLOCK DIAGRAM B0 OE A0 B1 A1 B2 A2 B3 A3 B4 A4 B5 A5 B6 A6 B7 A7 MARCH 2003 |
