onsemi MC74LVX4245DWG

The 74LVX4245 is a 24−pin dual−supply, octal translating transceiver that is designed to interface between a 5.0 V bus and a 3.0 V bus in a mixed 3.0 V / 5.0 V supply environment such as laptop computers using a 3.3 V CPU and 5.0 V LCD display. The A port interfaces with the 5V bus; the B port interfaces with the 3.0 V bus. The Transmit/Receive (T/R̅) 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 (OE̅) input, when High, disables both A and B ports by placing them in 3−State. The 74LVX4245 is a is a dual−supply device well capable of bidirectional signal voltage translation. This level shifting ability provides an excellent interface between low voltage CPU local bus and a standard 5.0 V I/O bus. The device control inputs can be controlled by either the low voltage CPU and core logic or a bus arbitrator with 5.0 V I/O levels. The LVX4245 is ideal for mixed voltage applications such as notebook computers using a 3.3 V CPU and 5.0 V peripheral devices.
