Description  
• Typical Propagation Delay (A to B, B to A) of 7ns at  
The CD74HCT242, ’HC243 and ’HCT243 silicon-gate  
CMOS three-state bidirectional inverting and non-inverting  
buffers are intended for two-way asynchronous communica-  
tion between data buses. They have high drive current out-  
puts which enable high-speed operation when driving large  
bus capacitances. These circuits possess the low power dis-  
sipation of CMOS circuits, and have speeds comparable to

The CD74HCT242 is an inverting buffer; the ’HC243 and  
’HCT243 are non-inverting buffers.
