MC74LVX4245

双电源八路翻译收发器，具有三态输出 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 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/Rbar 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 OEbar input, when High, disables both A and B ports by placing them in 3-State.
