Description

The PI74AUC164245 is a 16-bit (dual-octal) noninverting bus

transceiver that contains two separate supply rails. B port (V

set to operate at 0.8 to 2.5V and A port (V

at 0.8 to 2.5V. This arrangement permits universal bidirectional

translation over the voltage ranges.

The PI74AUC164245 is designed for asynchronous communication

between data buses. Data is transmitted from the A bus to the B bus

or vice versa, depending on the logic level at the direction control

(DIR)input. The output-enable (OE) input is used to disable outputs

so buses are isolated.

The control pins,

The device is fully specified for partial-power-down applications

using I

damaging current backflow through the device when it is powered

down.

To ensure the high impedance state during power up or power

down, the output-enable (OE) input should be tied to V

a pullup resistor, the minimum value of the resistor is determined

by the current-sinking capability of the driver.
