Description

The 54LVX4245 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 of 54LVX4245(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 TRI-STATE condition. The A port interfaces of 54LVX4245 with the 5V bus; the B port interfaces with the 3V bus.

The 54LVX4245 is suitable for mixed voltage applications such as systems using 3.3V memories which must interface with existing buses or other components operating at 5.0V.
