General Description
The 鈥橝C541 is an octal buffer/line driver designed to be em-
ployed as memory and address drivers, clock drivers and
bus oriented transmitter/receivers. The 鈥橝C541 is a nonin-
verting option of the 鈥橝C540.
This device is similar in function to the 鈥橝C244 while provid-
ing flow-through architecture (inputs on opposite side from
outputs). This pinout arrangement makes this device espe-
cially useful as an output port for microprocessors, allowing
ease of layout and greater PC board density.
