4-BIT BUS SWITCH

IDT74FST3125

FEATURES:

DESCRIPTION:

−

Bus switches provide zero delay paths

TheFST3125belongtoIDT'sfamilyofBusswitches. Busswitchdevices

performthe functionofconnectingorisolatingtwoports withoutproviding

anyinherentcurrentsinkorsource capability. Thus theygenerate little or

nonoise oftheirownwhile providinga lowresistance pathforanexternal

driver. Thesedevicesconnectinputandoutputportsthroughann-channel

FET. Whenthegate-to-sourcejunctionofthis FETis adequatelyforward-

biasedthe device conducts andthe resistance betweeninputandoutput

ports is small. Withoutadequatebias onthegate-to-sourcejunctionofthe

FET, the FETis turnedoff, therefore withnoVCC applied, the device has

hotinsertioncapability.

Extended commercial range of –40°C to +85°C

Low switch on-resistance: FST3xxx – 5Ω

TTL-compatible input and output levels

ESD > 2000V per MIL-STD-883, Method 3015; > 200V using

machine model (C = 200pF, R = 0)

−

Available in QSOP, SOIC, and TSSOP Packages

Thelowon-resistanceandsimplicityoftheconnectionbetweeninputand

outputports reduces the delayinthis pathtoclose tozero.

The FST3125 is a 4-bit TTL-compatible bus switch. The xOE pins

provide individualenable controlfor eachof the four bits.
