16-BIT UNIVERSAL BUS DRIVER
WITH 3-STATE OUTPUTS
SCES154G – DECEMBER 1998 – REVISED FEBRUARY 2000
description (continued)
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
The SN74AVC16334 is characterized for operation from –40°C to 85°C.
