General Description
The LCX541 is an octal buffer/line driver designed to be
employed as memory and address drivers, clock drivers
and bus oriented transmitter/receivers. The LCX541 is a
non inverting option of the LCX540.
This device is similar in function to the LCX244 while
providing flow-through architecture (inputs on opposite
side from outputs). This pinout arrangement makes this
device especially useful as an output port for micropro-
cessors, allowing ease of layout and greater PC board
density.
The LCX541 is designed for low voltage applications
with capability of interfacing to a 5V signal environment.
The LCX541 is fabricated with an advanced CMOS
technology to achieve high speed operation while
maintaining CMOS low power dissipation.
