3.3V QUAD ACTIVE LOW SWITCH

FOR HOT SWAP APPLICATIONS

(HOTSWITCH™)

DESCRIPTION:

FEATURES:

The QS3VH125 HotSwitchQuadbus switchis speciallydesignedfora

hot-swappingenvironment. The QS3VH125has verylowONresistance,

resulting in under 250ps propagation delay through the switch. The

switches can be turned ON under the control of individual LVTTL-

compatibleactivelowOutputEnablesignalsforbidirectionaldataflowwith

noaddeddelayorgroundbounce. IntheOFFandONstates,theswitches

are 5V-tolerant. Inthe OFFstate,the switches offerveryhighimpedence

attheterminals.

NOTES:

1. This parameter is guaranteed but not production tested.

2. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time

constant for the switch alone is of the order of 0.25ns at CL = 50pF. Since this time constant is much smaller than the rise and fall times of typical

driving signals, it adds very little propagation delay to the system. Propagation delay of the bus switch, when used in a system, is determined by the

driving circuit on the driving side of the switch and its interaction with the load on the driven side.

3. Minimums are guaranteed but not production tested.

4. Maximum toggle frequency for OE control input.
