1 / 8 page 1 INDUSTRIALTEMPERATURERANGE IDTQS3VH244 2.5V / 3.3V 8-BIT HIGH BANDWIDTH BUS SWITCH AUGUST 2002 2002 Integrated Device Technology, Inc. DSC-5894/9 c IDTQS3VH244 INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS 2.5V / 3.3V 8-BIT HIGH BANDWIDTH BUS SWITCH FUNCTIONAL BLOCK DIAGRAM DESCRIPTION: The QS3VH244 HotSwitch is a high bandwidth, 8-bit bus switch. The QS3VH244 hasverylowONresistance,resultinginunder250pspropagation delay through the switch. The switches can be turned ON under the control oftheLVTTL-compatiblexGsignalforbidirectionaldataflowwithnoaddeddelay orgroundbounce. IntheONstate,theswitchescanpasssignalsupto5V. In theOFFstate,theswitchesofferveryhighimpedenceattheterminals. Thecombinationofnear-zeropropagationdelay,highOFFimpedence,and over-voltage tolerance makes the QS3VH244 ideal for high performance communicationsapplications. The QS3VH244 is characterized for operation from -40 °C to +85°C. 1G 1 Y1 1 Y2 1 Y3 1 Y4 1 A1 1 A2 1 A3 1 A4 2G 2 Y1 2 Y2 2 Y3 2 Y4 2 A1 2 A2 2 A3 2 A4 The IDT logo is a registered trademark of Integrated Device Technology, Inc. APPLICATIONS: • Hot-swapping • 10/100 Base-T, Ethernet LAN switch • Low distortion analog switch • Replaces mechanical relay • ATM 25/155 switching • Bus switching and isolation 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 • Low RON - 4 Ω Ω Ω Ω Ω typical • 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 - up to 500MHz • LVTTL-compatible control Inputs • Undershoot Clamp Diodes on all switch and control Inputs • Low I/O capacitance, 4pF typical • Available in QSOP and TSSOP packages |
