SEMICONDUCTOR TECHNICAL DATA  
The MC74LVX245 is an advanced high speed CMOS octal bus  
transceiver.  
It is intended for two–way asynchronous communication between data  
buses. The direction of data transmission is determined by the level of the  
T/R input. The output enable pin (OE) can be used to disable the device,  
so that the buses are effectively isolated.  
All inputs are equipped with protection circuits against static discharge.

APPLICATION NOTES  
1. Do not force a signal on an I/O pin when it is an active output, damage may  
occur.  
2. All floating (high impedence) input or I/O pins must be fixed by means of  
pull up or pull down resistors or bus terminator ICs.
