IDTQS32XVH384 2.5V/3.3V 20-BIT HIGH BANDWIDTH BUS SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS 2.5V/3.3V 20-BIT HIGH BANDWIDTH BUS SWITCH FEATURES: IDTQS32XVH384 DESCRIPTION: • N channel FET switches with no parasitic diode to VCC – Isolation under power-off conditions – No DC path to VCC or GND – 5V tolerant in OFF and ON state • 5V tolerant I/Os Ω typical • Low RON - 4Ω • 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 48-pin QVSOP (S1) package The QS32XVH384 HotSwitch is a high bandwidth, 20-bit bus switch. The QS32XVH384 has very low ON resistance, resulting in under 250ps propagation delay through the switch. Four banks of five switches are controlled by independent (xOE), LVTTL compatible signals for bidirectional data flow with no added delay or ground bounce. In the ON state, the switches can pass signals up to 5V. In the OFF state, the switches offer very high impedence at the terminals. The combination of near-zero propagation delay, high OFF impedance, and over-voltage tolerance makes the QS32XVH384 ideal for high performance communications applications. The QS32XVH384 is characterized for operation from -40°C to +85°C. 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 A4 B4 A14 B14 A5 B5 A15 B15 A9 B9 A19 B19 1OE 4OE 3OE 2OE The IDT logo is a registered trademark of Integrated Device Technology, Inc.

This parameter is guaranteed but not production tested. 3. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.2ns at CL = 50pF. Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the system. Propagation delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. 4. Minimums are guaranteed but not production tested. 5.
