The control-function implementation GND 21 1B8 22 2B8 23 2DIR 24 28 GND 27 1A8 26 2A8 25 OE minimizes external timing requirements.
These devices can be used as two 8-bit transceivers or one 16-bit transceiver.
They allow data transmission 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 that the buses are effectively isolated.
When OE is low, the device is active.
The B port has an equivalent 25-Ω series output resistor to reduce ringing.
Active bus-hold inputs also are on the B port to hold unused or floating inputs at a valid logic level.
The A port provides for the prech...
