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
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
Ordering Code:
Devices also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
Pb-Free package per JEDEC J-STD-020B.
