74LVT2240 • 74LVTH2240
Low Voltage Inverting Octal Buffer/Line Driver
with 3-STATE Outputs
and 25
: Series Resistors in the Outputs
General Description
The LVT2240 and LVTH2240 are inverting octal buffers
and line drivers designed to be employed as memory
address drivers, clock drivers and bus oriented transmitters
or receivers which provides improved PC board density.
The equivalent 25
: Series resistors helps reduce output
overshoot and undershoot.
The LVTH2240 data inputs include bushold, eliminating the
need for external pull-up resistors to hold unused inputs.
These inverting octal buffers and line drivers are designed
for low-voltage (3.3V) VCC applications, but with the capa-
bility to provide a TTL interface to a 5V environment. The
LVT2240 and LVTH2240 are fabricated with an advanced
BiCMOS technology to achieve high speed operation simi-
lar to 5V ABT while maintaining low power dissipation.
Features
s Input and output interface capability to systems at
5V VCC
s Equivalent 25
: Series resistors on outputs
s Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs (74LVTH2240),
also available without bushold feature (74LVT2240)
s Live insertion/extraction permitted
s Power Up/Down high impedance provides glitch-free
bus loading
s Outputs source/sink
12 mA/12 mA
s Latch-up performance exceeds 500 mA
s ESD performance:
Human-body model
