74LVT244, 74LVTH244  
Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs  
Features  
General Description  
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 V  
CC  
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  
Power Up/Down high impedance provides glitch-free  
bus loading  
These octal buffers and line drivers are designed for low-  
Outputs source/sink –32mA/+64mA  
Functionally compatible with the 74 series 244  
Latch-up performance exceeds 500mA  
ESD performance:  
voltage (3.3V) V applications, but with the capability to  
CC  
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.
