U74LVC4245
U74LVC4245 is OCTAL BUS TRANSCEIVER AND 3.3V TO 5V SHIFTER manufactured by Unisonic Technologies.
DESCRIPTION
This 8-bit (octal) noninverting bus transceiver contains two separate supply rails; B port has VCCB, which is set at 3.3V, and A port has VCCA, which is set at 5V. This allows for translation from a 3.3V to a 5V environment, and vice versa.
The U74LVC4245 device is designed for asynchronous munication between data buses.
The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input.
The output-enable ( OE ) input can be used to disable the device so the buses are effectively isolated. The control circuitry (DIR, OE ) is powered by VCCA.
The U74LVC4245 device terminal out allows the designer to switch to a normal all-3.3V or all-5V 20-terminal U74LVC4245 device without board relay out.
