MC74LVX4245  
Dual Supply Octal  
Translating Transceiver  
with 3−State Outputs  
The 74LVX4245 is a 24−pin dual−supply, octal translating  
transceiver that is designed to interface between a 5.0 V bus and a 3.0 V  
bus in a mixed 3.0 V / 5.0 V supply environment such as laptop  
computers using a 3.3 V CPU and 5.0 V LCD display. The A port  
interfaces with the 5V bus; the B port interfaces with the 3.0 V bus.  
The Transmit/Receive (T/R) input determines the direction of data  
flow. Transmit (active−High) enables data from the A port to the B  
port. Receive (active−Low) enables data from the B port to the A port.  
The Output Enable (OE) input, when High, disables both A and B  
ports by placing them in 3−State.
