General Description
The LVT244 and LVTH244 are octal buffers and line
drivers designed to be employed as memory address
drivers, clock drivers and bus oriented transmitters or
receivers which provide improved PC board density.
The LVTH244 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 LVT244
and LVTH244 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining low power dissipation.
