1 / 8 page 1 INDUSTRIALTEMPERATURERANGE IDTQS3VH245 2.5V / 3.3V 8-BIT HIGH BANDWIDTH BUS SWITCH 2003 Integrated Device Technology, Inc. DSC-5775/6 c IDTQS3VH245 INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS 2.5V / 3.3V 8-BIT HIGH BANDWIDTH BUS SWITCH FUNCTIONAL BLOCK DIAGRAM DESCRIPTION: TheQS3VH245 HotSwitch8-bitbusswitchisahighbandwidthbusswitch. The QS3VH245 has very low ON resistance, resulting in under 250ps propagationdelaythroughtheswitch. TheswitchescanbeturnedONunder thecontroloftheLVTTL-compatibleOutputEnable signalforbidirectionaldata flowwithnoaddeddelayorgroundbounce. IntheONstate,theswitchescan passsignalsupto5V. IntheOFFstate,theswitchesofferveryhighimpedence attheterminals. Thecombinationofnear-zeropropagationdelay,highOFFimpedance,and over-voltage tolerance makes the QS3VH245 ideal forhigh performance communicationsapplications. The QS3VH245 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 • 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, SOIC, and TSSOP packages B0 OE A0 B1 A1 B2 A2 B3 A3 B4 A4 B5 A5 B6 A6 B7 A7 MARCH 2003 |
