DESCRIPTION/ORDERING INFORMATION

This octal bus transceiver is designed for 1.65-V to

3.6-V V_CCoperation.

The SN74LVC245A 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 effectively are isolated.
