74LVX240 Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs
74LVX240
Low Voltage Octal Buffer/Line Driver with
3-STATE Outputs
General Description
The LVX240 is an octal 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
Input voltage translation from 5V to 3V
Ideal for low power/low noise 3.3V applications
Guaranteed simultaneous switching noise level and
dynamic threshold performance
Ordering Code:
Devices also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
(Note 2)
Note 1: Absolute Maximum Ratings are those values beyond which the
safety to the device cannot be guaranteed. The device should not be oper-
ated at these limits. The parametric values defined in the Electrical Charac-
teristics 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.
