74ACTQ541
Quiet Series Octal Buffer/Line Driver
with 3-STATE Outputs
General Description
The 74ACTQ541 is an octal buffer/line driver designed to
be employed as memory and address drivers, clock drivers
and bus oriented transmitter/receivers.
This device is similar in function to the 74ACTQ244 while
providing flow-through architecture (inputs on opposite side
from outputs). This pinout arrangement makes this device
especially useful as an output port for microprocessors,
allowing ease of layout and greater PC board density.
The 74ACTQ541 utilizes FACT Quiet Series錚?technology
to guarantee quiet output switching and improved dynamic
threshold performance. FACT Quiet Series features GTO錚?/div>
output control and undershoot corrector in addition to split
ground bus for superior performance.
