IDT74LVC2245A

NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

This bus transceiver of the IDT74LVC2245A is built using advanced dual metal CMOS technology. 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 directioncontrol (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 IDT74LVC2245A 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.
