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

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.

Ordering Code:

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

Pb-Free package per JEDEC J-STD-020B.

Note 1: “_NL” indicates Pb-Free package (per JEDEC J-STD-020B). Device available in Tape and Reel only.
