General Description
The LVT2244 and LVTH2244 are 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 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
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.
