General Description
The ’FCT240isan inverting octal bufferandline driverde-
signedtobe employedasa memory address driver, clock
driverand bus oriented transmitteror receiver which pro-
vides improvedPC board density.
FACTTM FCT utilizes NSC quiet series technologyto pro-
vide improved quiet output switchingand dynamic threshold
performance.
FACT FCT features GTOTM output control and undershoot
correctorin additiontoa split groundbusfor superior per-
formance.
