74LVT2244 • 74LVTH2244  
Low Voltage Octal Buffer/Line Driver  
with 3-STATE Outputs  
and 25: Series Resistors in the Outputs  
General Description  
Features  
■ Input and output interface capability to systems at  
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.  
5V VCC  
■ Equivalent 25 -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).  
The LVTH2244 data inputs include bushold, eliminating the  
need for external pull-up resistors to hold unused inputs.  
■ Live insertion/extraction permitted  
■ Power Up/Down high impedance provides glitch-free  
bus loading  
These octal buffers and line drivers are designed for low-  
voltage (3.3V) VCC applications, but with the capability to  
■ Outputs source/sink 12 mA/ 12 mA  
■ Latch-up performance exceeds 500 mA  
■ ESD performance:  
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.  
Human-body model 2000V  
Machine model 200V
