The 74LVX3245MTCX is a dual-supply, 8-bit translating transceiver that is designed to interface between a 3V bus and a 5V 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 3V bus; the B Port interfaces with the 5V bus. The 74LVX3245MTCX is suitable for mixed voltage applications such as notebook computers using 3.3V CPU and 5V peripheral components.
