Octal Buffer/Line Driver with TRI-STATE

Outputs

General Description

The ’AC540 is an octal buffer/line drivers designed to be em­ployed as memory and address drivers, clock drivers and
bus oriented transmitter/receivers.

These devices are similar in function to the ’AC240 while
providing flow-through architecture (inputs on opposite side
from outputs).Thispinoutarrangementmakes these devices
especially useful as output ports for microprocessors, allow­ing ease of layout and greater PC board density.
