2.5V/3.3V 20-BIT HIGH

BANDWIDTH BUS SWITCH

FEATURES:

DESCRIPTION:

• N channel FET switches with no parasitic diode to VCC

– Isolation under power-off conditions

– No DC path to VCC or GND

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 bidirec-

tional data flow with no added delay or ground bounce. In the ON state, the

switchescanpasssignalsupto5V. IntheOFFstate,theswitchesoffervery

high impedence at the terminals.

– 5V tolerant in OFF and ON state

• 5V tolerant I/Os

• Low RON - 4Ω typical

• Flat R^ONcharacteristics over operating range

• Rail-to-rail switching 0 - 5V

The combination of near-zero propagation delay, high OFF impedance,

and over-voltage tolerance makes the QS32XVH384 ideal for high perfor-

mance communications applications.

• Bidirectional dataflow with near-zero delay: no added ground

bounce

• Excellent R^ONmatching between channels

• VCC operation: 2.3V to 3.6V

The QS32XVH384 is characterized for operation from -40°C to +85°C.

• 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

APPLICATIONS:

• Hot-swapping

• 10/100 Base-T, Ethernet LAN switch

• Low distortion analog switch

• Replaces mechanical relay

• ATM 25/155 switching
