74LVX541
Low Voltage Octal Buffer/Line Driver with
3-STATE Outputs
General Description
The LVX541 is an octal non-inverting buffer and line driver
designed to be employed as a memory address driver,
clock driver and bus oriented transmitter or receiver which
provides improved PC board density. The inputs tolerate
up to 7V allowing interface of 5V systems to 3V systems.
Features
s Input voltage translation from 5V to 3V
s Ideal for low power/low noise 3.3V applications
s Guaranteed simultaneous switching noise level and
dynamic threshold performance

Note 1: 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 “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Note 2: Unused inputs must be held HIGH or LOW. They may not float
