SN74AVC16245
16-BIT BUS TRANSCEIVER
WITH 3-STATE OUTPUTS
SCES142L – JULY 1998 – REVISED MAY 2005
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
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 partial-power-down applications using I
off
. The I
off
circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
The SN74AVC16245 is characterized for operation from –40°C to 85°C.
