FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
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
switching noise.
TheQS3V245isspeciallydesignedfordirectinterfacebetween3.3Vand
2.5Vdeviceswithoutanyexternalcomponents.Whenoperatingfroma3.3V
supply, the logic high level at the switch output is clamped to 2.5V when the
switchinputsignalexceeds2.5V.Thisdevicecanbeusedforswitching2.5V
buseswithoutsignalattenuation.TheONresistanceat3.3VVCC islessthan
5
typical, providing near zero propagation delay through the switch.
Absence of DC path from switch I/O pins to VCC or ground makes QS3V245
an ideal device for hot swapping applications.
The QS3V245 is characterized for operation from -40
°C to +85°C.
