Octal Buffer/Line Driver with 3-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). This pinout arrangement makes these

devices especially useful as output ports for microproces-

sors, allowing ease of layout and greater PC board density.

Ordering Code:

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.

Pb-Free package per JEDEC J-STD-020B.
