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) VCC 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.
Features
s Input and output interface capability to systems at
5V VCC
s Equivalent 25
:-Series resistors on outputs
s Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs (74LVTH2244),
also available without bushold feature (74LVT2244).
s Live insertion/extraction permitted
s Power Up/Down high impedance provides glitch-free
bus loading
s Outputs source/sink
12 mA/12 mA
s Latch-up performance exceeds 500 mA
s ESD performance:
Human-body model
! 2000V
Machine model
! 200V
Charged-device model
! 1000V
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.
