Bus Hold circuitry to retain last active state during Tri-state鈩?/div>
Available in SSOP and TSSOP packages
Description
Atmel鈥檚 AT16373 devices provide maximum speed in temporary data storage. They
can be operated as either two separate 8 bit latches or as a single 16-bit latch by use
of the output enable and the latch enable. The AT16373 has very low ground bounce
and excellent input noise rejection, giving the user stable signals in a high speed
environment. These devices can drive very large loads while operating in a high speed
transparent mode.
