IDTQS3VH16861 INDUSTRIAL TEMPERATURE RANGE 2.5V / 3.3V 20-BIT FLOW-THROUGH PIN OUT, HIGH BANDWIDTH BUS SWITCH QUICKSWITCH PRODUCTS 2.5V/ IDTQS3VH16861 3.3V 20-BIT FLOW-THROUGH PIN OUT, HIGH BANDWIDTH BUS SWITCH FEATURES: DESCRIPTION: N channel FET switches with no parasitic diode to Vcc The QS3VH16861 HotSwitch with 20-bit flow-though pin out is a high Isolation under power-off conditions bandwidth bus switch. The QS3VH16861 has very low ON resistance, No DC path to Vcc or GND resulting in under 250ps propagation delay through the switch. The switches 5V tolerant in OFF and ON state are controlled by active low enable (BEx) controls. In the ON state, the 5V tolerant I/Os switches can pass signals up to 5V. In the OFF state, the switches offer very Low RON - 4 typical high impedence at the terminals. Flat RON characteristics over operating range The combination of near-zero propagation delay, high OFF impedance, Rail-to-rail switching 0 - 5V and over-voltage tolerance makes the QS3VH16861 ideal for high perfor- Bidirectional dataflow with near-zero delay: no added ground mance communications applications. bounce The QS3VH16861 is characterized for operation from -40C to +85C. Excellent RON matching between channels Vcc operation: 2.3V to 3.6V High bandwidth - up to 500 MHz LVTTL-compatible control Inputs Undershoot Clamp Diodes on all switch and control Inputs Low I/O capacitance, 4pF typical Available in TSSOP 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 A10 B10 A9 B9 A19 B19 BE1 BE2 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
