16-Bit Latches
Functional Description
CY74FCT16373T and CY74FCT162373T are 16-bit D-type
latches designed for use in bus applications requiring high
speed and low power. These devices can 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.
Flow-through pinout and small shrink packaging aid in
simplifying board layout. The output buffers are designed with
power-off disable feature that allows live insertion of boards.
The CY74FCT16373T is ideally suited for driving
high-capacitance loads and low-impedance backplanes.
The CY74FCT162373T has 24-mA balanced output drivers
with current limiting resistors in the outputs. This reduces the
need for external terminating resistors and provides for
minimal undershoot and reduced ground bounce. The
CY74FCT162373T is ideal for driving transmission lines.
