Product Summary
The 74LVX4245MTCX 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 Z condition. The A port interfaces with the 5V bus; the B port interfaces with the 3V bus. The LVX4245 is suitable for mixed voltage applications such as laptop computers using 3.3V CPU and 5V LCD displays.
