74LCX541
Low Voltage Octal Buffer/Line Driver
with 5V Tolerant Inputs and Outputs
General Description
Features
■ 5V tolerant input and outputs
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.
■ 2.3V–3.6V VCC specifications provided
■ 6.5 ns tPD max (VCC 3.3V), 10 A ICC max
■ Power-down high impedance inputs and outputs
■ Supports live insertion/withdrawal (Note 1)
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.
■
24 mA output drive (VCC 3.0V)
■ Implements patented noise/ EMI reduction circuitry
■ Latch-up performance exceeds JEDEC 78 conditions
■ ESD performance:
The LCX541 is designed for low voltage (2.5V or 3.3V) VCC
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.
Human body model 2000V
Machine model 200V
■ Leadless Pb-Free DQFN package
Note 1: To ensure the high-impedance state during power up or down, OE
should be tied to V
through a pull-up resistor: the minimum value or the
CC
resistor is determined by the current-sourcing capability of the driver.

Note 4: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated
at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Ratings. The “Recom-
mended Operating Conditions” table will define the conditions for actual device operation.
Note 5: I Absolute Maximum Rating must be observed.

Note 6: Unused inputs or I/O's must be held HIGH or LOW. They may not float.
