IDT74LVC2245A
DESCRIPTION:
This bus transceiver is built using advanced dual metal CMOS technol-
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.
Inputs can be driven from either 3.3V or 5V devices. This feature allows
the use of this device as a translator in a mixed 3.3V/5V environment.
The LVC2245A has series resistors in the device output structure of the
"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.
