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 micro-
processors, allowing ease of layout and greater PC
board density.
The 74ACTQ541 utilizes FACT Quiet Series™ technol-
ogy to guarantee quiet output switching and improved
dynamic threshold performance. FACT Quiet Series
features GTO™ output control and undershoot corrector
in addition to split ground bus for superior performance.
