General Description
The ’ACTQ541isan octal buffer/line driver designedtobe
employed asmemoryand addressdrivers, clock driversand
bus oriented transmitter/receivers.
This deviceis similarin functiontothe ’ACTQ244 whilepro-
viding flow-through architecture (inputson opposite side
from outputs). This pinout arrangement makesthis device
especially usefulasan output portfor microprocessors,al-
lowing easeof layoutand greaterPC board density.
The ’ACTQ541utilizesNSC’s FACTTM Quiet Series technol-
ogyto guarantee quiet output switchingand improveddy-
namic threshold performance. FACT Quiet Series features
GTO output controland undershoot correctorin additionto
split groundbusfor superior performance.
Features ICCandIOZ reducedby 50% Guaranteed simultaneous switching noise leveland
dynamic threshold performance Guaranteed pin-to-pin skewAC performance Inputs and outputson opposite sidesof packagefor
easy board layout Non-inverting TRI-STATE outputs Guaranteed4kV minimum ESD immunity TTL compatible inputs Outputs source/sink24mA
