74LVT244, 74LVTH244 Rev. 1.5.0
January 2008
74LVT244, 74LVTH244
Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs
Features
Input and output interface capability to systems at
5V VCC
Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs (74LVTH244),
also available without bushold feature (74LVT244)
Live insertion/extraction permitted
Power Up/Down high impedance provides glitch-free
bus loading
Outputs source/sink –32mA/+64mA
Functionally compatible with the 74 series 244
Latch-up performance exceeds 500mA
ESD performance:
– Human-body model
> 2000V
– Machine model
> 200V
– Charged-device model
> 1000V
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) VCC applications, but with the capability to
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.
All packages are lead free per JEDEC: J-STD-020B standard.
