description
The ’AC245 octal bus transceivers are designed
for
asynchronous
two-way
between data buses. The control-function
implementation
minimizes
requirements.
communication
external
timing
When the output-enable (OE) is low, the device
passes noninverted 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.
A high on
OE
disables the device so that the buses
are effectively isolated.
The SN54AC245 is characterized for operation
over the full military temperature range of –55
°
C
to 125
°
C. The SN74AC245 is characterized for
operation from –40
°
C to 85
°
