OCTAL BUS TRANSCEIVERS

WITH 3-STATE OUTPUTS



DESCRIPTION

The U74AHC245 octal bus transceivers is designed for

asynchronous two-way communication between data buses. The

control-function

implementation

minimizes

external

timing

requirements.

The device allows 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 VCC through a pullup resistor; the

minimum value of the resistor is determined by the current-sinking

capability of the driver.



FEATURES

* Operating range 2V to 5.5V VCC
