Description

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. The output buffers of CY74FCT16841T and CY74FCT162841T are designed with a power-off disable feature to allow live insertion of boards.

The CY74FCT16841T is ideally suited for driving high-capacitance loads and low-impedance backplanes.

The CY74FCT162841T 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 CY74FCT162841T is ideal for driving transmission lines.
