DESCRIPTION/ORDERING INFORMATION
This octal bus transceiver is designed for 1.65-V to
3.6-V V
CC
operation.
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.
