Low Voltage Octal Buffer/Line Driver
with 5V Tolerant Inputs and Outputs
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 pro-
viding flow-through architecture (inputs on opposite side
from outputs). This pinout arrangement makes this device
especially useful as an output port for microprocessors,
allowing ease of layout and greater PC board density.
The LCX541 is designed for low voltage (2.5V or 3.3V) V
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.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
