74LVT2244
74LVTH2244
Low Voltage Octal Buffer/Line Driver
with 3-STATE Outputs
and 25 Series Resistors in the Outputs
General Description
The LVT2244 and LVTH2244 are octal buffers and line
drivers designed to be employed as memory address driv-
ers, 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 LVTH2244 data inputs include bushold, eliminating the
need for external pull-up resistors to hold unused inputs.
These octal buffers and line drivers are designed for low-
voltage (3.3V) V
CC
applications, but with the capability to
provide a TTL interface to a 5V environment. The LVT2244
and LVTH2244 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining low power dissipation.
