description/ordering information

The ’AHC245 octal bus transceivers are designed

for asynchronous two-way communication

between data buses. The control-function

implementation minimizes external timing

requirements.

These devices 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.

To ensure the high-impedance state during power

up or power down, OE should be tied to V

1 20 19

through a pullup resistor; the minimum value of

the resistor is determined by the current-sinking

capability of the driver.
