description
These octal bus transceivers are designed for
asynchronous two-way communication between
data buses. The control-function implementation
minimizes external timing requirements.
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
upon the logic level at the direction-control (DIR)
input. A high on OE disables the device so that the
buses are effectively isolated.
The SN54ACT245 is characterized for operation
over the full military temperature range of –55
°C
to 125
°C. The SN74ACT245 is characterized for
operation from –40
°C to 85°C.
