16-BIT BUFFER/DRIVER

WITH 3-STATE OUTPUTS

SCAS567H – MARCH 1996 – REVISED MARCH 2005

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators

in a mixed 3.3-V/5-V system environment.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors

with the bus-hold circuitry is not recommended.

preventing damaging current backflow through the device when it is powered down.
