DESCRIPTION:
ogy. The LVC2245A device is designed for asynchronous communication
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 use of this device as a translator in a mixed 3.3V/5V environment.
"B" port which will significantly reduce line noise when used with light loads.
The driver has been designed to drive ±12mA at the designated threshold
levels.
This bus transceiver is built using advanced dual metal CMOS technol-
Inputs can be driven from either 3.3V or 5V devices. This feature allows
