IDTQS32XVH245

2.5V / 3.3V 16-BIT HIGH

BANDWIDTH BUS SWITCH

FEATURES:

DESCRIPTION:

• N channel FET switches with no parasitic diode to VCC

– Isolationunderpower-offconditions

– No DC path to VCC or GND

TheQS32XVH245HotSwitchisahighbandwidth,16-bitbusswitch. The

QS32XVH245 has very low ON resistance, resulting in under 250ps propa-

gation delay through the switch. The switches can be turned ON under the

controloftheLVTTL-compatibleOutputEnable(OEx)signalforbidirectional

dataflowwithnoaddeddelayorgroundbounce. IntheONstate,theswitches

can pass signals up to 5V. In the OFF state, the switches offer very high

impedenceattheterminals.

– 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

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

bounce

Thecombinationofnear-zeropropagationdelay,highOFFimpedance,and

over-voltagetolerancemakestheQS32XVH245idealforhighperformance

communicationsapplications.

• Excellent RON matching between channels

• VCC operation: 2.3V to 3.6V

TheQS32XVH245ischaracterizedforoperationfrom-40°Cto+85°C.5°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 40-pin QVSOP package

APPLICATIONS:

• Hot-swapping

• 10/100 Base-T, Ethernet LAN switch

• Low distortion analog switch

• Replaces mechanical relay

• ATM 25/155 switching
