MC74VHC245  
Octal Bus Buffer/Line Driver  
The MC74VHC245 is an advanced high speed CMOS octal bus  
transceiver fabricated with silicon gate CMOS technology. It achieves  
high speed operation similar to equivalent Bipolar Schottky TTL  
while maintaining CMOS low power dissipation.  
It is intended for twoway asynchronous communication between  
data buses. The direction of data transmission is determined by the  
level of the DIR 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.

= PbFree Package  
Do not force a signal on an I/O pin when it is an active output,  
damage may occur.  
All floating (high impedance) input or I/O pins must be fixed by  
means of pull up or pull down resistors or bus terminator ICs.  
(Note: Microdot may be in either location)  
A parasitic diode is formed between the bus and V terminals.

ORDERING INFORMATION  
Therefore, the VHC245 cannot be used to interface 5 V to 3 V  
systems directly.
