IDTQS3VH861 2.5V / 3.3V 10-BIT FLOW-THROUGH PIN OUT, HIGH BANDWIDTH BUS SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH PRODUCTS IDTQS3VH861 2.5V / 3.3V 10-BIT FLOW-THROUGH PIN OUT, HIGH BANDWIDTH BUS SWITCH FEATURES: DESCRIPTION: N channel FET switches with no parasitic diode to VCC The QS3VH861 HotSwitch with 10-bit flow-through pin out is a high Isolation under power-off conditions bandwidth bus switch. The QS3VH861 has very low ON resistance, No DC path to VCC or GND resulting in under 250ps propagation delay through the switch. The 5V tolerant in OFF and ON state switches are controlled by active low enable (BE) control. In the ON 5V tolerant I/Os state, the switches can pass signals up to 5V. In the OFF state, the Low RON - 4 typical switches offer very high impedence at the terminals. Flat RON characteristics over operating range The combination of near-zero propagation delay, high OFF imped- Rail-to-rail switching 0 - 5V ance, and over-voltage tolerance makes the QS3VH861 ideal for high Bidirectional dataflow with near-zero delay: no added ground performance communications applications. bounce The QS3VH861 is characterized for operation from -40C to +85C. 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 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 B0 A9 B9 BE The IDT logo is a registered trademark of Integrated Device Technology, Inc.
