74LVX4245  
8-Bit Dual Supply Translating Transceiver  
with 3-STATE Outputs  
General Description  
Features  
Bidirectional interface between 5V and 3V buses  
The LVX4245 is a dual-supply, 8-bit translating transceiver  
that is designed to interface between a 5V bus and a 3V  
bus in a mixed 3V/5V supply environment. The Transmit/  
Receive (T/R) input determines the direction of data flow.  
Transmit (active-HIGH) enables data from A Ports to B  
Ports; Receive (active-LOW) enables data from B Ports to  
A Ports. The Output Enable input, when HIGH, disables  
both A and B Ports by placing them in a high impedance  
condition. The A Port interfaces with the 5V bus; the B Port  
interfaces with the 3V bus.  
Control inputs compatible with TTL level  
5V data flow at A Port and 3V data flow at B Port  
Outputs source/sink 24 mA at 5V bus; 12 mA at 3V bus  
Guaranteed simultaneous switching noise level and  
dynamic threshold performance  
Implements patented EMI reduction circuitry  
Functionally compatible with the 74 series 245  
The LVX4245 is suitable for mixed voltage applications  
such as laptop computers using 3.3V CPU’s and 5V LCD  
displays.
