The CY74FCT16841T and CY74FCT162841T are 20-bit D-type latches designed for use in bus applications requiring high speed and low power. These devices can be used as two independent 10-bit latches, or as a single 10-bit latch, or as a single 20-bit latch by connecting the Output Enable (OE) and Latch (LE) inputs. Flow-through pinout and small shrink packaging aid in simplifying board layout. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
