3.3ÄV ABT 16ÄBIT BUS TRANSCEIVER
WITH 3ÄSTATE OUTPUTS
SCAS772C â JUNE 2004 â REVISED JANUARY 2008
description/ordering information (continued)
When VCC is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 1.5 V, OE shall be tied to VCC through a pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the driver.
This device is fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry
disables the outputs, preventing damaging current backflow through the device when it is powered down. The
power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,
which prevents driver conflict.
