description

These octal bus transceivers are designed for

asynchronous two-way communication between

data buses. The control-function implementation

minimizes external timing requirements.

(TOP VIEW)

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.
