Functional Description
This device is a 16-bit, D-type latch, designed for use in bus
applications requiring high speed and low power. It can either
be used as two independent 8-bit latches, or as a single 16-bit
latch by connecting the Output Enable (OE) and Latch (LE)
inputs. The outputs are 24-mA balanced output drivers with
current limiting resistors to reduce the need for external
terminating resistors and provide for minimal undershoot and
reduced ground bounce. Flow-through pinout and small shrink
packaging aid in simplifying board layout.
The CY74FCT163373 is designed with inputs and outputs
capable of being driven by 5.0V buses, allowing its use in
mixed voltage systems as a translator. The outputs are also
designed with a power off disable feature enabling its use in
applications requiring live insertion.
