74LVT244 •74LVTH244  
Low Voltage Octal Buffer/Line Driver  
with 3-STATE Outputs  
General Description  
Features  
Input and output interface capability to systems at  
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.  
5V VCC  
Bushold data inputs eliminate the need for external  
pull-up resistors to hold unused inputs (74LVTH244),  
also available without bushold feature (74LVT244)  
The LVTH244 data inputs include bushold, eliminating the  
need for external pull-up resistors to hold unused inputs.  
Live insertion/extraction permitted  
These octal buffers and line drivers are designed for low-  
voltage (3.3V) VCC applications, but with the capability to  
Power Up/Down high impedance provides glitch-free  
bus loading  
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.  
Outputs source/sink 32 mA/+64 mA  
Functionally compatible with the 74 series 244  
Latch-up performance exceeds 500 mA
