Description

The 74LVX4245 is a 24pin dualsupply, octal translating transceiver MC74LVX4245 is  designed to interface between a 5V bus and a 3V bus in a mixed 3V/5V supply environment such as laptop computers using a 3.3V CPU and 5V LCD display. The A port interfaces with the 5V bus; the B port interfaces with the 3V bus.

The Transmit/Receive (T/R) input MC74LVX4245 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.
