IDTQS3VH125 INDUSTRIAL TEMPERATURE RANGE 2.5V / 3.3V QUAD ACTIVE LOW, HIGH BANDWIDTH SWITCH IDTQS3VH125 QUICKSWITCH PRODUCTS 2.5V / 3.3V QUAD ACTIVE LOW, HIGH BANDWIDTH BUS SWITCH FEATURES: DESCRIPTION: N channel FET switches with no parasitic diode to VCC The QS3VH125 is a high bandwidth, Quad bus switch. The QS3VH125 Isolation under power-off conditions has very low ON resistance, resulting in under 250ps propagation delay No DC path to VCC or GND through the switch. The switches can be turned ON under the control 5V tolerant in OFF and ON state of individual LVTTL-compatible active low Output Enable signals for 5V tolerant I/Os bidirectional data flow with no added delay or ground bounce. In the ON Low RON - 4 typical state, the switches can pass signals up to 5V. In the OFF state, the Flat RON characteristics over operating range switches offer very high impedence at the terminals. Rail-to-rail switching 0 - 5V The combination of near-zero propagation delay, high OFF imped- Bidirectional dataflow with near-zero delay: no added ground ance, and over-voltage tolerance makes the QS3VH125 ideal for high bounce performance communications applications. Excellent RON matching between channels The QS3VH125 is characterized for operation from -40C to +85C. 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 SOIC packages APPLICATIONS: Hot-swapping 10/100 Base-T, Ethernet LAN switch Low distortion analog switch Replaces mechanical relay ATM 25/155 switching FUNCTIONAL BLOCK DIAGRAM 1A 2A 3A 4A 1OE 2OE 3OE 4OE 1Y 2Y 3Y 4Y The IDT logo is a registered trademark of Integrated Device Technology, Inc.
