description  
The ’ACT16825 18-bit buffers/drivers are  
designed specifically to improve both the  
performance and density of 3-state memory  
address drivers, clock drivers, and bus-oriented  
receivers and transmitters.

The ’ACT16825 can be used as two 9-bit buffers  
or one 18-bit buffer. They provide true data from  
A to Y.  
The 3-state control gate is a 2-input NOR gate;  
therefore, if either output-enable (OE1 or OE2)  
input is high, all nine affected outputs are in the  
high-impedance state.  
2OE1  
2OE2  
The 74ACT16825 is packaged in TI’s shrink small-outline package, which provides twice the I/O pin count and  
functionality of standard small-outline packages in the same printed-circuit-board area.  
The 54ACT16825 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
74ACT16825 is characterized for operation from –40°C to 85°C.
