Description

Atmel’s 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.

Note: 1. This 8-bit latch function is repeated a second time on each device.
