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-

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.

Ordering Information

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
