intended for two-way transmission from “A” bus to “B” bus or  
“B” bus to “A”. The logic level present on the direction input  
(DIR) determines the data direction. When the output enable  
input (OE) is HIGH, the outputs are in the high-impedance  
state.  
• Exceeds 2kV ESD Protection per MIL-STD-883,  
Method 3015
