IDTQS34XV245

MULTIWIDTH™ BUS SWITCH

FEATURES:

DESCRIPTION:

• 5Ω bidirectional switches connect inputs to outputs

• Pin compatibility with QS3245

The QS34XV245 is a set of 32-bit high speed bus switches controlled by

LVTTL-compatibleactivelowenablesignal.Whenclosed,theswitchesexhibit

nearzeropropagationdelaywithoutgeneratingadditionalgroundbounceor

switchingnoise.

• 250ps propagation delay

• Undershoot clamp diodes on all switch and control inputs

• LVTTL-compatible control inputs

• Available in 80-pin QVSOP package

APPLICATIONS:

• 3.3V to 2.5V Voltage translation

• 2.5V to 1.8V Voltage translation

• PCI bus isolation hot swap

TheQS34XV245ischaracterizedforoperationfrom-40°Cto+85°C.
