3.3V HIGH SPEED BUS SWITCH

FEATURES:

DESCRIPTION:

• 5Ω bi-directional switches connect inputs to outputs

• Pin compatibility with QS3245

The QS3V245 is an 8-bit high speed bus switch controlled by LVTTL-

compatibleactivelowenablesignal.Whenclosed,theswitchesexhibitnear

zero propagation delay without generating additional ground bounce or

switchingnoise.

• 250ps propagation delay

• Undershoot Clamp Diodes on all switch and control Inputs

• LVTTL-compatible control Inputs

TheQS3V245isspeciallydesignedfordirectinterfacebetween3.3Vand

2.5Vdeviceswithoutanyexternalcomponents.Whenoperatingfroma3.3V

buseswithoutsignalattenuation.TheONresistanceat3.3VVCC islessthan

5Ω typical, providing near zero propagation delay through the switch.

AbsenceofDCpathfromswitchI/OpinstoVCC orgroundmakesQS3V245

an ideal device for hot swapping applications.

• Available in SOIC and QSOP packages

APPLICATIONS:

• 3.3V to 2.5V voltage translation

• 2.5V to 1.8V voltage translation

• PCI bus isolation hot swap

The QS3V245 is characterized for operation from -40°C to +85°C.
