General Description
The LVT2244 and LVTH2244 are octal buffers and line drivers designed to be employed as memory address drivers, clock drivers and bus oriented transmitters or receivers which provides improved PC board density. The equivalent 25Ω-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
■ Input and output interface capability to systems at 5V VCC
■ Equivalent 25Ω-Series resistors on outputs
■ Bushold data inputs eliminate the need for external
   pull-up resistors to hold unused inputs (74LVTH2244),
   also available without bushold feature (74LVT2244)
■ Live insertion/extraction permitted
■ Power Up/Down high impedance provides glitch-free bus loading
■ Outputs source/sink –12mA/+12mA
■ Latch-up performance exceeds 500mA
■ ESD performance:
   – Human-body model > 2000V
   – Machine model > 200V
   – Charged-device model > 1000V
