Dual Supply Octal
Translating Transceiver
with 3State Outputs
The 74LVX4245 is a 24pin dualsupply, 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 (activeHigh) enables data from the A port to the B
port. Receive (activeLow) 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 3State.
Features
