74LVT244 • 74LVTH244
Low Voltage Octal Buffer/Line Driver
with 3-STATE Outputs
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_CC 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.
Features
s Input and output interface capability to systems at
5V V_CC
s Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs (74LVTH244),
also available without bushold feature (74LVT244)
s Live insertion/extraction permitted
s Power Up/Down high impedance provides glitch-free
bus loading
s Outputs source/sink 32 mA/64 mA
s Functionally compatible with the 74 series 244
s Latch-up performance exceeds 500 mA
s ESD performance:
Human-body model ! 2000V
Machine model ! 200V
Charged-device model ! 1000V
