Description  
• Typical Propagation Delay (A to B, B to A) of 7ns at  
The Harris CD74HCT242, CD74HC243 and CD74HCT243  
silicon-gate CMOS three-state bidirectional inverting and  
non-inverting buffers are intended for two-way asynchronous  
communication between data buses. They have high drive  
current outputs which enable high-speed operation when  
driving large bus capacitances. These circuits possess the  
low power dissipation of CMOS circuits, and have speeds
