MC74LVX245  
Octal Bus Transceiver  
With 5 V−Tolerant Inputs  
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.
